Q41) A user reports that their laptop battery is draining unusually fast, even when the device is idle. Which of the following is the MOST likely cause?

A) Background applications consuming CPU resources
B) Outdated BIOS
C) Defective RAM
D) Incorrect date and time settings

Answer: A) Background applications consuming CPU resources

Explanation:

When a laptop battery drains quickly while idle, the most common cause is that applications or processes are running in the background, consuming CPU cycles and preventing the system from entering low-power states. Background applications can include system updates, antivirus scans, or poorly optimized software that continuously uses CPU or disk resources. This constant activity requires energy, which leads to faster battery depletion.

Option A) is correct because background applications can significantly increase power consumption. Modern laptops rely on CPU throttling and sleep states to conserve battery, but active background processes prevent these mechanisms from functioning efficiently. Users can verify this by checking the Task Manager on Windows or Activity Monitor on macOS to see which applications are consuming the most CPU. Power-saving settings like adjusting screen brightness, disabling unused peripherals, or using battery saver modes can also help reduce drain caused by background tasks.

Option B) Outdated BIOS can impact system stability, hardware compatibility, and sometimes power management, but it rarely causes sudden or unusual battery drain during normal idle operation. While a BIOS update may improve battery efficiency in some cases, it is not typically the primary cause of fast drain compared to background processes.

Option C) Defective RAM usually manifests as system instability, crashes, or failure to boot rather than excessive battery drain. RAM errors do not directly cause high CPU usage; therefore, it is unlikely to be the reason for rapid battery depletion.

Option D) Incorrect date and time settings may cause issues with scheduled tasks or certificate errors in applications but do not directly lead to high battery usage. While misconfigured time settings can indirectly trigger some background processes like repeated sync attempts, the effect on battery is minor compared to CPU-intensive applications running continuously.

In troubleshooting battery issues, the correct approach involves first examining which processes are consuming the most resources. Users can disable unnecessary startup programs, schedule intensive tasks like antivirus scans when plugged in, and keep the operating system and drivers updated to ensure optimal power management. Power plan configurations, such as enabling the balanced or battery saver mode, also influence how aggressively the CPU and peripherals conserve energy. Monitoring battery health is important because even with proper optimization, aging batteries lose their maximum capacity over time, which exacerbates drain caused by background applications. Overall, identifying and limiting unnecessary background processes provides the fastest and most effective improvement in battery life.

Q42) A technician needs to deploy multiple Windows 10 devices with the same configuration and applications across the company. Which deployment method is the MOST efficient?

A) Unattended installation using an answer file
B) Manual installation on each device
C) PXE boot installation for each device individually
D) Using System Restore on each device

Answer: A) Unattended installation using an answer file

Explanation:

Deploying multiple Windows 10 devices with identical configuration and applications is a scenario where efficiency is critical. An unattended installation using an answer file allows the technician to automate the installation process, providing pre-configured settings for user accounts, network configuration, time zones, applications, and other system parameters. This eliminates the need for manual intervention during each setup, saving time and reducing errors.

Option A) is correct because answer files, typically created using Windows System Image Manager (SIM), automate all responses that would otherwise be manually entered during the installation process. This ensures consistency across all deployed devices and can include installation of drivers, joining devices to a domain, and configuring security settings. IT administrators can also combine unattended installations with deployment tools such as Microsoft Deployment Toolkit (MDT) or Windows Deployment Services (WDS) for even greater efficiency in large-scale rollouts.

Option B) Manual installation on each device is inefficient for multiple systems because it requires individual attention for every device. Each installation takes significant time and introduces the risk of configuration errors, inconsistent software versions, and missing drivers. This method may only be feasible for very small deployments or ad hoc setups.

Option C) PXE boot installation allows network-based deployment but performing PXE boot for each device individually still requires manual steps unless combined with automation tools. While PXE itself is a deployment method, without unattended configuration, it does not achieve maximum efficiency for large-scale, identical installations.

Option D) Using System Restore is not suitable for deploying new devices. System Restore restores a system to a previous state on the same device, rather than creating a standardized setup across multiple new devices. It is primarily a recovery tool for troubleshooting rather than deployment.

For efficient deployment, organizations often use a combination of tools: first creating a master reference image configured with desired applications and settings, then automating installations using unattended answer files and deployment servers. This approach minimizes downtime, ensures uniformity, and reduces repetitive manual work, especially in enterprise environments where dozens or hundreds of devices need to be configured identically.

Q43) A user reports that their desktop computer is producing a loud clicking noise from the hard drive area. Which of the following actions should the technician perform FIRST?

A) Backup the user’s data immediately
B) Replace the motherboard
C) Update the hard drive firmware
D) Run disk cleanup

Answer: A) Backup the user’s data immediately

Explanation

A loud clicking noise from a hard drive is a strong indicator of impending mechanical failure, often referred to as the “click of death.” In these cases, the first priority is to protect the user’s data because the drive may fail completely at any moment. Mechanical hard drives have moving components such as platters, read/write heads, and actuators, which can wear out or become misaligned. Clicking usually occurs when the read/write heads repeatedly attempt to locate data but cannot, which is symptomatic of serious hardware failure.

Option A) is correct because data backup is the immediate priority to prevent data loss. The technician should copy essential files to an external drive, network storage, or cloud service before any further troubleshooting or repairs. Ensuring data integrity takes precedence over hardware repair in situations where drive failure is imminent.

Option B) Replacing the motherboard is unnecessary in this scenario because a clicking hard drive typically indicates a mechanical issue within the drive itself, not the motherboard or system electronics. Swapping the motherboard would not resolve the clicking or prevent potential data loss.

Option C) Updating the hard drive firmware is generally not a solution for mechanical failures. Firmware updates can fix logical or interface issues but will not prevent physical components from failing or resolve clicking noises caused by failing heads or motors.

Option D) Running disk cleanup has no effect on mechanical hardware issues. Disk cleanup only removes temporary files, caches, and other non-essential data from the storage device and does not address mechanical failure, clicking, or potential data loss.

After backing up the data, the technician can then replace the hard drive with a new unit, restore data from the backup, and verify that the system operates correctly. Some technicians may attempt data recovery from a failing drive if backups are incomplete, but this process can be expensive and time-consuming. Preventive maintenance, monitoring drive health using SMART attributes, and regular backups are essential to avoid situations where mechanical failure causes catastrophic data loss.

Q44) A user reports that their wireless laptop loses connectivity when moving between different rooms in the office. Which of the following is the MOST likely cause?

A) Weak signal strength from the wireless access points
B) Outdated network drivers
C) Incorrect IP address configuration
D) Faulty network cable

Answer: A) Weak signal strength from the wireless access points

Explanation:

When a wireless laptop loses connectivity while moving around an office, the most common cause is weak signal strength. Wireless signals degrade over distance, and obstacles such as walls, metal partitions, and electronic interference can further reduce signal quality. If the access points are not strategically placed or if their coverage does not overlap sufficiently, devices may lose connectivity when moving out of range.

Option A) is correct because weak signal strength directly correlates with connection drops during mobility. Users can verify signal strength using the Wi-Fi icon on the taskbar or advanced utilities like wireless analyzers. Solutions include repositioning access points, adding additional access points to improve coverage, or enabling seamless roaming protocols such as 802.11r to allow smooth transitions between APs.

Option B) Outdated network drivers can cause performance issues, connection drops, or instability, but the problem described is location-specific. If connectivity drops only occur when moving between rooms, driver issues are less likely the primary cause. Updating drivers is still recommended but will not fully resolve signal coverage problems.

Option C) Incorrect IP address configuration can prevent devices from connecting to the network entirely, but it does not typically cause connectivity loss that depends on physical location. Devices with improper IP addresses either fail to connect or experience consistent network issues, independent of movement.

Option D) Faulty network cable is irrelevant for wireless connectivity, as no wired connection is involved. A defective cable could affect wired connections but will not influence Wi-Fi performance or signal loss when moving around.

To address weak signal strength, network administrators may conduct a site survey to map wireless coverage, measure signal-to-noise ratios, and optimize access point placement. Channel overlap and interference from other devices can also be managed to improve connectivity. Proper planning ensures users can roam seamlessly without losing connection, which is especially important in large offices or multi-floor buildings where wireless coverage must be robust and consistent.

Q45) A technician receives a support ticket indicating that a user cannot log in to their Windows workstation. The error states “Account locked due to multiple failed login attempts.” Which of the following actions should the technician perform FIRST?

A) Unlock the user’s account in Active Directory
B) Reinstall the operating system
C) Replace the keyboard
D) Reset the BIOS password

Answer: A) Unlock the user’s account in Active Directory

Explanation:

The error message “Account locked due to multiple failed login attempts” indicates that the user’s account has been temporarily locked by security policies, which is common in enterprise environments to prevent unauthorized access. The first action should be to unlock the account in the directory service managing user accounts, typically Active Directory in Windows domains. This restores the user’s ability to log in while maintaining security controls and audit trails.

Option A) is correct because unlocking the account directly addresses the problem without unnecessary hardware replacement or system reinstallation. Administrators can unlock accounts using tools like the Active Directory Users and Computers console or PowerShell commands. It is important to verify the identity of the user before unlocking the account to ensure proper security procedures are followed.

Option B) Reinstalling the operating system is extreme and unnecessary in this situation. The problem is related to account lockout, not corruption or OS failure. Reinstallation would waste time, disrupt the user’s environment, and offer no additional security benefit.

Option C) Replacing the keyboard is irrelevant because the user’s credentials are correct, and the system is merely enforcing a lockout policy. Hardware issues are not implicated in an account lockout scenario.

Option D) Resetting the BIOS password is also unrelated. BIOS security protects hardware settings and startup processes, not user login credentials within Windows or Active Directory. It will not resolve account lockout issues.

After unlocking the account, it is advisable to investigate the cause of the failed login attempts. Common causes include forgotten passwords, malware attempting unauthorized logins, cached credentials, or other devices attempting to authenticate with old credentials. Educating users on password management and enabling multi-factor authentication can reduce account lockout frequency and improve overall security posture in enterprise environments.

Q46) A user complains that their desktop PC is extremely slow when opening applications, and the hard drive LED is constantly active. Which of the following should the technician check FIRST?

A) Available free space on the hard drive
B) Operating system version
C) Installed RAM capacity
D) Monitor resolution

Answer: A) Available free space on the hard drive

Explanation:

 When a desktop PC becomes extremely slow, and the hard drive LED is constantly active, the primary suspect is high disk usage, often caused by insufficient free space. Hard drives need a certain amount of free space to function efficiently, especially for virtual memory, paging files, and temporary file storage. If the drive is nearly full, the operating system struggles to manage read/write operations, which can drastically reduce system performance and cause applications to open very slowly.

Option A) is correct because free disk space is critical for system performance. When a drive is nearly full, file fragmentation increases, and the operating system has difficulty creating temporary files needed for multitasking. Users can check available free space through File Explorer or the Disk Management utility in Windows. If free space is low, the technician should advise the user to remove unnecessary files, uninstall unused applications, or expand storage capacity. In some cases, moving data to an external drive or cloud storage can alleviate the issue.

Option B) Operating system version affects compatibility and features but does not directly explain constant hard drive activity or overall system slowness unless it is outdated and incompatible with installed applications. Upgrading the OS may help in long-term performance, but checking disk space provides a more immediate diagnostic step.

Option C) Installed RAM capacity influences system responsiveness, but the question indicates heavy disk activity rather than memory paging alone. While low RAM can cause paging to the disk, the initial step should be to check if the hard drive itself is running out of space before assuming memory is the bottleneck. Additional RAM may improve performance, but it does not solve a nearly full hard drive.

Option D) Monitor resolution affects graphics display and screen clarity, not general system performance or hard drive activity. Changing resolution will not resolve slow application loading or constant disk usage.

To diagnose such performance issues systematically, the technician should first analyze disk usage and free space, then examine background processes that may be causing high I/O, and finally consider hardware upgrades or configuration changes. Utilities such as Resource Monitor, Task Manager, and disk cleanup tools help identify excessive disk usage and improve overall system responsiveness. Addressing disk space constraints is often the quickest and most effective solution for a slow PC exhibiting constant hard drive activity.

Q47) A user reports that their smartphone battery drains unusually fast. The device is also getting warm even when not in use. Which of the following is the MOST likely cause?

A) Applications running in the background
B) Faulty battery connector
C) Cracked screen
D) Incorrect time settings

Answer: A) Applications running in the background

Explanation

Smartphones rely on battery conservation mechanisms such as low-power states, screen dimming, and CPU throttling. When a device drains battery rapidly and becomes warm even while idle, it indicates that applications or processes are consuming resources continuously. Background apps may include social media apps, location services, push notifications, or automatic updates. Continuous CPU activity generates heat and draws more current from the battery, resulting in both rapid drain and a warm device.

Option A) is correct because background applications are the most common reason for unexpected battery drain. Users can check battery usage statistics in the smartphone’s settings to identify which apps are consuming the most power. Techniques to mitigate drain include restricting background activity, disabling location services, uninstalling unnecessary apps, or enabling battery saver modes that limit background processing. Regular monitoring ensures that rogue or poorly optimized applications do not impact battery longevity.

Option B) Faulty battery connectors could prevent charging or cause intermittent power loss, but they do not usually lead to continuous heat generation while the device is in use. A connector issue may manifest as device shutdowns or failure to charge rather than constant drain when idle.

Option C) Cracked screens do not affect battery drain unless the screen is causing touch input errors that trigger continuous processing. However, the question mentions battery and heat issues, which are independent of physical screen damage. Cracks primarily compromise display functionality and durability, not power consumption.

Option D) Incorrect time settings do not directly affect battery usage. Although some applications rely on time and may attempt synchronization repeatedly, this effect is minimal compared to the significant drain caused by active background apps.

The proper troubleshooting approach includes identifying resource-intensive applications, optimizing settings, and ensuring the operating system and apps are updated. Users can also clear cache files, reduce notifications, and disable features like always-on GPS or push email to preserve battery life. In enterprise environments, mobile device management policies can enforce restrictions on background activity, ensuring consistent performance across devices. By addressing background processes, the smartphone can return to expected performance levels, extending both battery runtime and device longevity.

Q48) A company wants to allow employees to connect personal devices to the corporate Wi-Fi while keeping internal resources secure. Which of the following network configurations BEST meets this requirement?

A) Implementing a guest wireless network with VLAN segmentation
B) Enabling WPA2 on the corporate SSID
C) Using MAC address filtering
D) Configuring static IP addresses for all devices

Answer: A) Implementing a guest wireless network with VLAN segmentation

Explanation:

 Allowing personal devices to connect to corporate Wi-Fi without compromising security requires isolating these devices from sensitive internal resources. Implementing a guest network with VLAN (Virtual Local Area Network) segmentation achieves this goal by separating traffic from personal devices and corporate systems. VLANs logically divide a network into multiple subnets, controlling which devices can access specific resources. Employees can use the guest network for internet access, while corporate servers and internal systems remain on a separate VLAN protected from potential threats.

Option A) is correct because guest networks with VLAN segmentation provide both usability and security. IT administrators can configure access controls, firewall rules, and bandwidth limitations for the guest VLAN. This setup prevents unauthorized access to sensitive data and reduces risk from malware-infected personal devices. VLANs are commonly used in enterprise environments to create logical boundaries without requiring additional physical infrastructure.

Option B) Enabling WPA2 on the corporate SSID secures the wireless network by encrypting traffic and requiring authentication. While this protects against unauthorized access, it does not segregate personal devices from internal resources. Employees with credentials could still access corporate systems if VLAN segmentation or other access controls are not in place.

Option C) Using MAC address filtering restricts network access to specific devices but is not scalable in environments with numerous personal devices. MAC addresses can also be spoofed, making this method less secure than proper VLAN segmentation.

Option D) Configuring static IP addresses does not inherently isolate personal devices or control access to internal resources. While static IPs may be useful for network management, they do not provide the logical separation needed to secure corporate systems from guest devices.

In practice, the implementation would involve creating a separate SSID for the guest network, assigning it to a different VLAN, and configuring firewall and access control rules to restrict traffic. This approach balances user convenience and security, enabling employees to use their devices while minimizing potential exposure to corporate resources. VLAN segmentation also allows IT to monitor traffic and enforce security policies more effectively across large networks.

Q49) A user reports that their desktop computer displays random blue screens of death (BSODs) after installing a new graphics card. Which of the following is the MOST likely cause?

A) Incompatible or outdated drivers
B) Low system RAM
C) Malfunctioning keyboard
D) Full hard drive

Answer: A) Incompatible or outdated drivers

Explanation:

 Random blue screen errors after hardware installation often indicate driver conflicts or incompatibility. When a new graphics card is installed, the operating system requires the correct device driver to communicate with the hardware. Outdated, missing, or incompatible drivers can cause system instability, kernel crashes, and BSOD errors. Installing the manufacturer-provided driver or updating to the latest version usually resolves the issue.

Option A) is correct because driver incompatibility is the most common cause of post-installation BSODs. The operating system relies on drivers to interact with hardware; if the driver fails to handle requests correctly, memory access violations or hardware conflicts can occur. Troubleshooting steps include booting into safe mode, uninstalling existing drivers, and installing the correct driver version from the manufacturer’s website. Some advanced graphics cards may also require BIOS updates or additional system configuration.

Option B) Low system RAM can cause performance degradation or application crashes but is unlikely to cause consistent BSODs triggered by new hardware installation. While insufficient RAM can stress the system, the timing of the BSODs immediately after installing a graphics card points to a driver-related issue rather than memory shortages.

Option C) Malfunctioning keyboard does not cause BSODs. Keyboard issues might result in input errors or unresponsive keys but are unrelated to system crashes or memory access violations.

Option D) A full hard drive can lead to slow performance, paging issues, or system instability, but it does not typically cause immediate BSODs triggered by new hardware installation. Disk space may exacerbate other issues but is not the root cause in this scenario.

Proper troubleshooting involves verifying driver compatibility, checking for system updates, ensuring sufficient power delivery to the graphics card, and testing the card in another system if needed. Drivers should be uninstalled cleanly before installing new ones, and utilities such as Display Driver Uninstaller (DDU) can help prevent conflicts. Monitoring system logs and BSOD error codes can further help pinpoint the cause. Resolving driver issues ensures stable operation, prevents repeated crashes, and maximizes hardware performance.

Q50) A user reports that their laptop is unable to connect to a corporate VPN. Other users on the same network can connect without issues. Which of the following should the technician check FIRST?

A) Local firewall or antivirus software
B) Corporate VPN server status
C) Physical network cables
D) Hard drive fragmentation

Answer: A) Local firewall or antivirus software

Explanation:

When a single laptop cannot connect to a VPN while others on the same network can, the issue is likely local to the device. Local firewalls or antivirus software may block VPN connections by preventing the VPN client from establishing outbound ports or filtering encrypted traffic. Security software often has default rules that restrict tunneling protocols such as IPsec, L2TP, or SSL VPNs. Temporarily disabling or configuring the firewall/antivirus to allow VPN traffic often resolves the connectivity issue.

Option A) is correct because local security configurations are the most common reason why one device cannot connect to a VPN while others succeed. The technician should check firewall rules, antivirus network filtering, and VPN client settings. Ensuring the client software is up to date and verifying credentials also help troubleshoot connectivity issues without affecting other users.

Option B) Corporate VPN server status is less likely the cause since other users can connect successfully. While server issues can prevent VPN access entirely, the scenario specifies that only one device experiences the problem, pointing to a local issue.

Option C) Physical network cables do not affect VPN connectivity if other network functions on the laptop work properly. If the device can browse the internet, ping servers, or communicate on the local network, the physical connection is functioning correctly.

Option D) Hard drive fragmentation affects performance but does not prevent VPN connectivity. Fragmentation slows file access and program launch times but does not interfere with network communication or VPN tunneling protocols.

After verifying the firewall and antivirus settings, the technician may also check VPN client logs for error messages, ensure proper authentication, and confirm that any split tunneling or security policies are correctly configured. By addressing local security software settings first, the technician can often restore VPN connectivity without unnecessary changes to server infrastructure or hardware.

Q51) A user reports that their laptop is overheating and frequently shutting down while running multiple applications. Which of the following is the MOST likely cause?

A) Dust accumulation in cooling vents and fans
B) Low battery charge
C) Incorrect screen resolution
D) Outdated keyboard drivers

Answer: A) Dust accumulation in cooling vents and fans

Explanation:

 Laptop overheating and unexpected shutdowns are typically caused by insufficient cooling. Dust accumulation in vents, fans, and heat sinks restricts airflow, preventing heat generated by the CPU, GPU, and other components from dissipating efficiently. When internal temperatures rise above safe thresholds, modern laptops implement thermal throttling or automatic shutdowns to prevent hardware damage.

Option A) is correct because physical obstructions in the cooling system are a common cause of overheating. Dust and debris block airflow and reduce the efficiency of cooling fans and heat sinks. The technician should inspect the laptop vents and fans, clean dust with compressed air, and ensure that the device is placed on a flat, hard surface to allow proper ventilation. In some cases, replacing thermal paste between the CPU/GPU and heat sinks can further improve heat transfer.

Option B) Low battery charge does not directly cause overheating. While some power-saving modes reduce CPU performance, insufficient battery will only prevent operation if the laptop cannot draw power from the battery or adapter. The described symptoms involve high temperature, not power limitations.

Option C) Incorrect screen resolution affects display clarity but has no impact on internal temperatures or system shutdowns. Higher resolutions may increase GPU workload slightly, but this alone rarely causes critical overheating unless paired with other issues.

Option D) Outdated keyboard drivers do not influence CPU, GPU, or fan operation. Driver issues related to peripherals may cause input lag or unresponsiveness but are unrelated to thermal events or automatic shutdowns.

Addressing overheating requires a combination of hardware maintenance and monitoring. Technicians should verify that cooling fans spin correctly, clean or replace clogged vents, and check system temperature using software utilities. Educating users about proper laptop placement and avoiding obstructed surfaces also helps prevent future thermal issues. Overheating, if left unresolved, can reduce hardware lifespan and cause permanent component failure, making prompt intervention critical.

Q52) A technician is deploying a new group of Windows 10 computers using a preconfigured system image. After deployment, some devices show missing device drivers. Which of the following is the BEST course of action?

A) Install the missing drivers from the manufacturer’s website
B) Reinstall the operating system manually on each device
C) Ignore the issue as Windows will auto-correct it later
D) Replace the motherboard on affected devices

Answer: A) Install the missing drivers from the manufacturer’s website

Explanation

When deploying a system image, it is common to encounter missing device drivers if the image does not include drivers for specific hardware components. Drivers are essential for proper communication between the operating system and hardware such as network adapters, graphics cards, and audio devices. Without correct drivers, devices may not function optimally or at all.

Option A) is correct because installing the missing drivers from the manufacturer’s website ensures that each component works properly. Technicians can either download drivers manually or use driver management tools to streamline the process. Updating drivers after deployment is standard practice to address hardware variations between different models or batches of devices. This approach resolves the issue efficiently without requiring full OS reinstallation.

Option B) Reinstalling the operating system manually is unnecessary and inefficient. The OS is already installed, and the only missing element is specific device drivers. Reinstallation would be time-consuming and redundant.

Option C) Ignoring the issue is unprofessional and may lead to nonfunctional hardware, reduced system performance, and user dissatisfaction. While Windows Update may automatically install some drivers over time, critical components like network adapters or proprietary graphics cards may remain unusable without manual intervention.

Option D) Replacing the motherboard is extreme and unwarranted. Missing drivers do not indicate hardware failure but rather a software configuration issue. Hardware replacement would not resolve missing driver problems and is a waste of resources.

The recommended workflow includes identifying all missing devices in Device Manager, downloading the appropriate drivers, and installing them. Automated deployment solutions can include driver packages within images or post-deployment scripts to streamline driver installation. Maintaining an updated driver repository ensures that new deployments have minimal post-installation issues, increasing efficiency and user satisfaction.

Q53) A user reports that their Windows PC frequently displays pop-up ads, even when the browser is closed. Which of the following is the MOST likely cause?

A) Malware infection
B) Full hard drive
C) Outdated monitor drivers
D) Incorrect system date and time

Answer: A) Malware infection

Explanation:

 Pop-up ads appearing outside of the browser context are strong indicators of malware or adware infection. Malware can inject scripts or run background processes that generate unsolicited advertisements, redirect users to malicious websites, or install additional unwanted software. These behaviors compromise system security and performance.

Option A) is correct because adware and certain malware variants are designed specifically to display pop-up ads, regardless of whether the browser is active. Technicians should run a full malware scan using trusted antivirus or anti-malware tools, remove identified threats, and ensure that the system is updated with security patches. Educating the user on safe browsing practices and avoiding suspicious downloads can prevent reinfection.

Option B) A full hard drive may cause slow performance or prevent new files from being saved but does not generate pop-up ads. Disk space issues affect storage capacity, not intrusive advertising behavior.

Option C) Outdated monitor drivers can cause display resolution or refresh rate issues, but they do not produce pop-up advertisements. Driver problems may affect visuals but are unrelated to software-generated adware.

Option D) Incorrect system date and time may cause certificate errors or prevent secure connections to websites, but it does not trigger pop-up ads. Time misconfiguration has minimal effect on malware behavior.

The appropriate response involves scanning the system, removing malicious programs, and possibly restoring the system to a clean state using tools like System Restore or recovery partitions. Technicians may also review installed programs for suspicious applications and browser extensions. Ongoing preventive measures, including anti-malware software and user education, help maintain a secure environment.

Q54) A user reports that their Wi-Fi connection frequently disconnects when moving around the office. Other devices connected to the same network do not experience this issue. Which of the following is the MOST likely cause?

A) Weak wireless adapter signal or driver issues
B) Network switch failure
C) ISP service outage
D) Incorrect DNS settings

Answer: A) Weak wireless adapter signal or driver issues

Explanation:

 When a single device experiences frequent Wi-Fi disconnections while others remain stable, the issue is typically local to the device. Wireless adapters may have weak signal reception due to poor placement, outdated drivers, or hardware degradation. Movement around the office can exacerbate weak signals, causing drops when the device moves out of range or encounters interference.

Option A) is correct because weak signal strength or driver problems directly impact wireless connectivity. Users can verify the signal strength, update drivers, and ensure that the adapter’s settings support roaming between access points. Adjusting power management settings or using external antennas (if supported) can also improve reception. Driver updates often resolve compatibility and stability issues, reducing connection drops.

Option B) Network switch failure would affect all devices connected to that switch, not just a single laptop. If the issue were switch-related, multiple users would experience connectivity problems simultaneously.

Option C) ISP service outage affects all devices attempting to access external networks. Since other users maintain connectivity, the ISP is unlikely to be the root cause.

Option D) Incorrect DNS settings may prevent websites from resolving correctly but do not typically cause frequent wireless disconnections. DNS issues affect name resolution rather than physical connectivity.

Technicians should start by checking the wireless adapter’s signal quality, updating drivers, and ensuring proper roaming and power management configurations. If necessary, moving closer to the access point or testing with a different network can isolate hardware or driver issues. Resolving adapter-specific problems restores stable connectivity while avoiding unnecessary network-wide troubleshooting.

Q55) A technician needs to install a new printer on a Windows 10 workstation. The printer supports both USB and network connections. Which of the following steps should the technician perform FIRST?

A) Connect the printer and install the appropriate driver
B) Configure the firewall to allow printer communication
C) Set the printer as the default device in Windows
D) Replace the printer toner cartridge

Answer: A) Connect the printer and install the appropriate driver

Explanation:

Installing a new printer on a Windows 10 workstation requires first establishing a communication link between the computer and the printer. This is accomplished by physically connecting the printer via USB or configuring it for network access and then installing the appropriate driver. The driver allows the operating system to understand the printer’s capabilities, manage print jobs, and enable additional features such as duplex printing, scanning, or advanced color settings.

Option A) is correct because connection and driver installation are prerequisites for any further configuration. Windows may automatically detect and install generic drivers, but manufacturer-provided drivers ensure full functionality and performance. The technician should follow the installation wizard or use the printer’s installation software to ensure proper setup.

Option B) Configuring the firewall may be necessary for network printers, but this step comes after the printer is connected and the system recognizes it. Configuring firewalls prematurely is unnecessary until the device attempts to communicate over the network.

Option C) Setting the printer as the default device is a post-installation step. The default printer determines where print jobs are sent by default, but this cannot be done until the system recognizes the new printer.

Option D) Replacing the toner cartridge is only relevant for printers that are out of toner or ink. For a brand-new printer, the installation process begins with connecting the device and installing drivers, not managing consumables.

Proper printer installation ensures compatibility, accessibility, and user satisfaction. Once drivers are installed, the technician can configure network settings, assign a default printer, and perform test prints to verify proper operation. This systematic approach prevents common errors, such as unrecognized devices or incomplete installation, and ensures that users can print reliably.

Q56) A user reports that their Windows 10 workstation is unable to print to a shared network printer. Other users can print successfully to the same printer. Which of the following should the technician check FIRST?

A) User’s network permissions on the shared printer
B) Printer toner levels
C) Hard drive free space on the workstation
D) BIOS version

Answer: A) User’s network permissions on the shared printer

Explanation:

When a single user cannot print to a shared network printer while others can, the issue is most likely related to access permissions. In Windows environments, printers can be shared with specific users or groups, and permissions control who can print, manage the printer, or see it in the network list. Without the proper permissions, the workstation may be able to see the printer but fail to send print jobs, resulting in errors.

Option A) is correct because verifying and adjusting the user’s network permissions on the shared printer is the first step. The technician should check the printer properties under the Sharing and Security tabs, ensuring that the user or their Active Directory group has the “Print” permission. If permissions are missing, adding the user restores access.

Option B) Printer toner levels do not affect the ability of a specific user to print if other users can print successfully. Low toner would impact print quality for everyone, not just one workstation.

Option C) Hard drive free space on the workstation affects local document storage and spool file creation, but typical user workloads rarely exhaust space completely. Since other users can print, local storage is unlikely to be the root cause.

Option D) BIOS version does not affect the ability to send print jobs to a network printer. BIOS controls hardware initialization, not operating system-level network or printer permissions.

After confirming permissions, the technician can check for other issues such as driver conflicts, cached print jobs, or network connectivity problems. Proper troubleshooting ensures the user can print without disrupting the network printer for others.

Q57) A technician is configuring a Windows 10 laptop to automatically install updates during off-hours. Which of the following settings should the technician modify?

A) Active hours and automatic update schedule
B) Power plan settings
C) Screen saver timeout
D) Device encryption settings

Answer: A) Active hours and automatic update schedule

Explanation:

Windows 10 includes an update management system that allows administrators and users to control when updates are installed. Configuring updates to occur during off-hours prevents interruptions during working periods and ensures the system remains secure with the latest patches. “Active hours” specify when the system is typically in use, and the automatic update schedule determines when Windows downloads and installs updates.

Option A) is correct because modifying active hours and the automatic update schedule directly controls when updates are applied. The technician can set active hours to match the user’s typical working schedule, ensuring that updates do not trigger reboots during important tasks. The system will then schedule updates outside of those hours, typically during the night or other downtime.

Option B) Power plan settings manage how the computer consumes energy, such as sleep timers or CPU performance, but they do not control update scheduling. Incorrect power plan settings may prevent the system from waking for updates, but this is secondary to setting the update schedule.

Option C) Screen saver timeout controls when the display turns off during inactivity and is unrelated to updates. Modifying screen saver settings will not affect the timing of Windows Update installations.

Option D) Device encryption settings protect data on the system but do not affect update scheduling. Encryption ensures security, but scheduling updates remains independent of encryption policies.

Proper configuration of active hours and automatic updates ensures that critical patches are applied without disrupting productivity. Administrators can also leverage Group Policy or Windows Update for Business policies to enforce consistent update schedules across multiple devices in enterprise environments. Monitoring update history ensures that patches are installed successfully and mitigates security vulnerabilities.

Q58) A user reports that their laptop is connecting to a Wi-Fi network but cannot access the internet. Other devices on the same network have no issues. Which of the following is the MOST likely cause?

A) Incorrect IP configuration on the laptop
B) ISP outage
C) Damaged Ethernet cable
D) Outdated display drivers

Answer: A) Incorrect IP configuration on the laptop

Explanation:

When a laptop connects to a Wi-Fi network but cannot access the internet while other devices function normally, the problem is usually local to that device. Incorrect IP configuration, such as an invalid IP address, subnet mask, or gateway, prevents proper routing of network traffic. If the laptop is set with a static IP that conflicts with another device or is outside the network’s range, it may appear connected but cannot communicate with the internet.

Option A) is correct because IP configuration issues are a common cause of this scenario. The technician should check the network adapter settings, ensure the laptop is set to obtain an IP address automatically via DHCP, or verify that manually assigned static IP addresses are correct. Running diagnostic commands like “ipconfig” and “ping” helps confirm connectivity to the gateway and external servers.

Option B) ISP outage affects all devices attempting to reach the internet. Since other devices work normally, the ISP is unlikely the cause.

Option C) Damaged Ethernet cable is irrelevant for Wi-Fi connections. The laptop uses wireless connectivity, so a physical cable would not affect network access unless the user is connected via wired Ethernet.

Option D) Outdated display drivers affect visual performance but have no impact on network communication. Issues like slow rendering or screen artifacts do not cause network connectivity problems.

After verifying IP settings, the technician may also check for firewall restrictions, proxy configurations, or security software blocking network access. Correcting misconfigured IP parameters restores internet connectivity while maintaining proper network security and functionality.

Q59) A company wants to secure all laptops in the organization in case of theft. Which of the following solutions BEST meets this requirement?

A) Implement full disk encryption and enable BitLocker
B) Set complex BIOS passwords
C) Disable wireless adapters
D) Install screen savers with passwords

Answer: A) Implement full disk encryption and enable BitLocker

Explanation:

Laptop theft is a serious security concern, and sensitive data must be protected even if the device falls into the wrong hands. Full disk encryption ensures that all data stored on the hard drive is encrypted and inaccessible without proper authentication. BitLocker, included in Windows 10 Pro and Enterprise editions, provides strong encryption and integrates with TPM (Trusted Platform Module) chips to enhance security.

Option A) is correct because full disk encryption prevents unauthorized access to data even if the laptop is stolen. BitLocker encrypts the entire drive, requiring a password, PIN, or key to unlock the system. This approach protects confidential information and meets regulatory compliance requirements for data security. Enabling recovery keys ensures that legitimate users can regain access if authentication fails.

Option B) Setting complex BIOS passwords helps protect hardware settings and prevents unauthorized booting from alternative devices but does not encrypt data. A thief could still remove the drive and access data on another system unless encryption is applied.

Option C) Disabling wireless adapters reduces remote attack surfaces but does not protect the data already stored on the laptop. Physical theft would still expose sensitive information.

Option D) Installing screen savers with passwords prevents casual access while the laptop is unattended but is ineffective against determined attackers. Screen lock only secures the logged-in session, not the underlying disk contents.

Comprehensive laptop security combines full disk encryption, strong authentication, and physical security measures. Organizations may also implement remote device tracking and wipe capabilities, ensuring that lost or stolen devices cannot be exploited. By prioritizing encryption, companies mitigate the primary risk of data exposure due to theft.

Q60) A user reports that their Windows 10 system is running slowly and consuming excessive CPU resources. Task Manager shows a process labeled “Windows Modules Installer Worker” using high CPU. Which of the following BEST describes the cause?

A) The process is installing or checking for Windows updates
B) The system is infected with malware
C) The hard drive is failing
D) The display driver is outdated

Answer: A) The process is installing or checking for Windows updates

Explanation

 “Windows Modules Installer Worker” (TiWorker.exe) is a legitimate Windows system process responsible for installing, modifying, and removing Windows updates and components. During update scans or installations, the process can consume high CPU and disk resources temporarily. This behavior is normal and typically resolves itself after updates are completed.

Option A) is correct because high CPU usage from this process is expected when Windows is performing updates in the background. Task Manager may show usage spikes, and users may experience slow performance until updates finish. Technicians can verify Windows Update history and ensure updates complete successfully. Patience is often the best solution, although restarting the system or scheduling updates for off-hours can reduce disruption.

Option B) Malware can cause high CPU usage, but the description of a known system process indicates legitimate activity. If suspicious behavior persists outside of update activity, malware scans can be performed to rule out infection.

Option C) Hard drive failure may result in slow performance, disk errors, or BSODs, but the specific CPU usage by a known Windows process does not indicate drive failure. Symptoms of drive failure typically involve read/write errors rather than consistent CPU spikes.

Option D) Outdated display drivers affect graphics performance and may cause rendering issues, but they do not trigger high CPU usage from “Windows Modules Installer Worker.” Graphics driver updates are unrelated to system update processes.

To optimize performance, users can schedule Windows updates for off-hours, temporarily pause updates during critical work, or use performance monitoring tools to observe resource consumption. Understanding the role of system processes like TiWorker.exe helps differentiate normal background activity from genuine performance problems or malware infections.
