Question 41 

A FortiGate administrator wants to restrict internal devices from reaching external malware domains while allowing safe web access. Which feature should be used?

A) NAT Policy
B) DoS Sensor
C) DNS Filter
D) SD-WAN Rules

Answer: C)

Explanation

NAT Policy translates internal IP addresses to public IPs and vice versa. Its primary purpose is network address translation and IP mapping for traffic leaving the network. While NAT enables communication and can control the source or destination, it does not inspect or block DNS queries to malicious domains. Therefore, NAT alone cannot restrict access to malware sites.

DoS Sensor monitors traffic for flood attacks and abnormal traffic patterns. It is designed to detect and mitigate denial-of-service attempts but does not analyze DNS requests or categorize web destinations. Its functionality is security-focused on volume-based attacks, not content or domain-based filtering.

DNS Filter analyzes DNS queries, categorizes domain names, and blocks access to malicious, phishing, or inappropriate websites based on FortiGuard threat intelligence. It can enforce policies without inspecting full HTTP traffic, making it lightweight yet effective for stopping access to malware domains while allowing safe web traffic. This aligns perfectly with the requirement described.

SD-WAN Rules optimize traffic routing based on performance, link health, or application criteria. They do not perform domain categorization or security analysis of DNS queries. While SD-WAN can prioritize or route traffic for efficiency, it does not provide protection against access to malicious domains.

DNS Filter is the correct answer because it specifically provides domain-level inspection and blocking based on threat intelligence. NAT Policy handles translation, DoS Sensor mitigates floods, and SD-WAN Rules optimize routing. Only DNS Filter effectively prevents devices from reaching malicious domains while allowing safe web access.

Question 42 

Which FortiGate feature allows traffic to bypass security inspection for trusted hosts while still logging sessions?

A) Flow-based Inspection
B) NP Accelerated Path
C) Proxy-based Inspection
D) Application Control

Answer: B)

Explanation 

Flow-based Inspection analyzes traffic as it streams through the firewall. It offers lower latency but still processes traffic through the CPU, applying security profiles inline. It does not selectively bypass inspection while retaining session logging for trusted hosts.

NP Accelerated Path leverages hardware NP6 processors to offload sessions from the CPU, allowing traffic to bypass intensive security inspection while still being counted and logged. This enables trusted hosts or high-performance flows to traverse the firewall efficiently while maintaining visibility. The feature provides a balance between performance and monitoring, making it ideal for scenarios requiring trusted traffic bypass.

Proxy-based Inspection buffers the entire file or session for deep inspection. While thorough, it increases latency and cannot bypass inspection selectively. It is intended for deep content scanning, not for performance-based bypass of trusted traffic.

Application Control identifies and classifies applications for policy enforcement, including those on non-standard ports. While it is critical for security, it does not provide a mechanism to bypass security inspection. It evaluates traffic, not accelerates or bypasses it.

NP Accelerated Path is the correct answer because it enables trusted traffic to bypass CPU-intensive inspection while maintaining session logs. Flow-based Inspection is inline without selective bypass, Proxy-based Inspection increases latency, and Application Control focuses on classification. Only NP Accelerated Path meets the requirement.

Question 43 

A FortiGate administrator notices VPN users are disconnected after a short idle period, even though the policy idle-timeout is set to 1 hour. What should be checked first?

A) SSL Certificate Expiration
B) Global Session TTL
C) NTP Server Settings
D) Proxy Profile

Answer: B)

Explanation 

SSL Certificate Expiration affects authentication for SSL connections, but it does not directly terminate active sessions based on timeout. Expired certificates may block new connections but do not interfere with session idle timers already in effect.

Global Session TTL sets the maximum lifetime for sessions across all policies. If the TTL is lower than the policy idle-timeout, sessions will terminate when the TTL expires, regardless of the policy configuration. This is the most common cause of premature session disconnections and should be checked first when idle sessions are dropping unexpectedly.

NTP Server Settings ensure system time synchronization. While important for certificate validation, logging, and scheduled tasks, they do not directly affect session timeout values. Incorrect time may cause logging discrepancies but does not close idle VPN sessions early.

Proxy Profile applies to explicit or web proxy traffic. It governs traffic inspection and content filtering but does not affect VPN session timers or idle session behavior.

Global Session TTL is the correct answer because it directly controls the maximum duration of sessions. SSL certificates, NTP settings, and Proxy Profiles do not influence idle session termination. Checking the session TTL is the first logical step when VPN sessions are dropping prematurely.

Question 44 

Which FortiGate feature allows dynamic segmentation of devices based on tags or posture from EMS or FortiNAC?

A) VLAN Pooling
B) Fabric-based Segmentation
C) MAC-based Policy
D) Traffic Shaping

Answer: B) 

Explanation

VLAN Pooling distributes clients across multiple VLANs for scalability and load balancing. While helpful in large wireless networks, it does not dynamically segment devices based on risk, posture, or tags. Its function is administrative and not security-driven.

Fabric-based Segmentation uses dynamic tags from Security Fabric components like FortiClient EMS or FortiNAC to place devices into specific security zones. This prevents lateral movement and enforces zero-trust principles by automatically adjusting policies based on device risk posture or compliance status. It allows real-time security segmentation and is the correct answer for dynamic isolation of endpoints.

MAC-based Policy allows rule enforcement based on device MAC addresses. While useful for identifying devices, it requires manual configuration and cannot dynamically adjust segmentation based on fabric intelligence. It is limited in scalability and responsiveness.

Traffic Shaping manages bandwidth allocation and prioritization. It focuses on performance rather than security segmentation and cannot dynamically isolate devices.

Fabric-based Segmentation is correct because it enforces dynamic, tag-based segmentation to prevent lateral movement. VLAN Pooling, MAC-based Policy, and Traffic Shaping do not provide dynamic, posture-aware segmentation.

Question 45 

Which FortiGate inspection mode buffers the entire file before scanning, allowing deeper analysis but increasing latency?

A) Flow-based Inspection
B) Proxy-based Inspection
C) IPS Offload
D) NAT Policy

Answer: B) 

Explanation 

Flow-based Inspection evaluates traffic as it streams through the firewall, providing low-latency performance. It does not buffer entire files and therefore cannot perform deep scanning of complete objects.

Proxy-based Inspection buffers the entire file or object before scanning, allowing full antivirus inspection, file type validation, and content analysis. This mode introduces additional latency but ensures thorough examination of objects before forwarding. It is ideal for environments where accuracy and deep inspection are more important than throughput.

IPS Offload uses hardware acceleration to scan packets for intrusion signatures efficiently. While it can perform deep packet inspection quickly, it does not buffer entire files and therefore cannot conduct the same deep object analysis as proxy-based inspection.

NAT Policy handles address translation for outbound and inbound traffic. It does not inspect or scan file content and therefore cannot perform deep scanning.

Proxy-based Inspection is correct because it provides full object buffering for deep analysis, unlike Flow-based Inspection or IPS Offload, and NAT Policy does not perform inspection at all.

Question 46 

A FortiGate administrator wants to prevent infected devices from communicating with known botnet command-and-control servers. Which feature should be used?

A) Web Filtering
B) Application Control
C) AntiBotnet
D) VLAN Tagging

Answer: C) 

Explanation 

Web Filtering categorizes websites and blocks access based on category or reputation. While it can block malicious websites, it is not specifically designed to detect the behavioral patterns of command-and-control traffic used by botnets. Its primary function is URL reputation and content categorization, not dynamic threat detection based on endpoint communication.

Application Control identifies applications and can restrict usage or block specific apps. While it provides visibility into applications that devices are running, it does not specifically monitor or block botnet command-and-control communications, which often use legitimate protocols or ports to evade detection. Therefore, Application Control alone cannot fully mitigate this threat.

AntiBotnet is designed to detect and block communication between infected devices and known malicious command-and-control servers. It uses behavioral analysis, threat intelligence, and domain reputation to identify suspicious patterns. Once a device is detected trying to reach a C2 server, FortiGate can block the communication and alert administrators. This direct correlation with C2 traffic makes AntiBotnet the most appropriate feature for preventing malware from maintaining control.

VLAN Tagging provides network segmentation by separating broadcast domains, improving management and security boundaries. While VLANs can help contain threats within a segment, they do not inspect outbound connections or detect malware command-and-control traffic. VLAN Tagging does not actively prevent infected devices from contacting external malicious servers.

AntiBotnet is the correct answer because it actively monitors and blocks botnet C2 communication using intelligence and behavioral analysis. Web Filtering blocks malicious URLs but not all C2 traffic, Application Control monitors applications but cannot fully detect C2 activity, and VLAN Tagging only segments networks without providing detection or blocking capabilities.

Question 47 

Which FortiOS feature is used to automatically adjust security policies based on device identity, risk score, or user role?

A) Web Filtering
B) Dynamic Policy
C) DoS Sensor
D) NP6 Offloading

Answer: B) 

Explanation 

Web Filtering analyzes web traffic and categorizes URLs to enforce access control or block malicious sites. Although it can be used in conjunction with security policies, it does not automatically adjust policies based on device identity, risk score, or user role. Its focus is content categorization and URL reputation, not adaptive policy enforcement.

Dynamic Policy enables the firewall to modify security policies automatically in response to changes in device posture, risk score, or user role. It leverages information from Security Fabric components such as EMS, FortiNAC, or FortiAuthenticator to apply real-time adjustments. This allows administrators to enforce zero-trust principles and ensure that access permissions are dynamically updated without manual intervention. Because it is explicitly designed for adaptive security, it is the correct choice.

DoS Sensor monitors traffic patterns to prevent flooding, resource exhaustion, and denial-of-service attacks. While important for network protection, it does not adjust policies based on device or user attributes. Its function is threat mitigation rather than adaptive policy enforcement.

NP6 Offloading improves performance by moving packet processing to hardware. While it enhances throughput and reduces CPU load, it does not provide dynamic policy adjustments or user/device-based control. Its function is performance-focused, not security posture-driven.

Dynamic Policy is correct because it directly modifies policies based on device identity, risk score, or user role. Web Filtering categorizes URLs, DoS Sensor protects against floods, and NP6 Offloading accelerates traffic. Only Dynamic Policy provides real-time adaptive policy enforcement.

Question 48 

In FortiManager, which ADOM mode allows devices running different FortiOS versions to coexist in the same ADOM?

A) Normal Mode
B) Mixed Mode
C) Restricted Mode
D) Transition Mode

Answer: B) 

Explanation

Normal Mode in FortiManager enforces strict firmware consistency across all devices within an ADOM (Administrative Domain). This means that every managed device in the ADOM must be running the same major FortiOS version. The main advantage of this approach is predictability: policies, templates, and configuration changes behave consistently across all devices because the underlying firmware features are identical. Normal Mode helps prevent compatibility issues that could arise from differences in feature sets or command syntax between versions. However, the strict requirement also limits flexibility. Devices running older or newer firmware versions cannot be added to the ADOM without first upgrading or downgrading them to match the enforced version. This makes Normal Mode less suitable for environments with phased upgrade plans or diverse device versions.

Mixed Mode, on the other hand, is specifically designed to address the need for flexibility in multi-version environments. In Mixed Mode, an ADOM can include devices running different major FortiOS versions. This allows organizations to manage all their devices from a single administrative domain even if some devices have not yet been upgraded or are temporarily running older firmware. Mixed Mode is particularly valuable for phased upgrade cycles, where not all devices can be updated at the same time, or in heterogeneous deployments with different FortiGate models requiring different firmware. Administrators can apply policies, run reports, and perform management tasks across all devices without being blocked by firmware discrepancies.

Restricted Mode focuses on limiting administrative access and controlling what administrators can do within an ADOM. It governs operational permissions and enforces restrictions on configuration changes but does not affect firmware compatibility. Devices within a Restricted Mode ADOM must still adhere to whatever firmware requirements the ADOM is operating under, whether Normal or Mixed. Its purpose is administrative control, not version management, so it does not provide a solution for environments that need to support multiple firmware versions.

Transition Mode is a temporary state used primarily for converting ADOMs from one mode to another or for migrating administrative domains. It is not intended for routine device management and does not provide inherent support for managing multiple firmware versions in a standard operational scenario. While it may facilitate a short-term transition, it cannot serve as a permanent solution for heterogeneous firmware environments.

Mixed Mode is the correct answer because it explicitly allows multiple FortiOS versions to coexist within a single ADOM. Normal Mode enforces uniformity and does not allow multi-version management. Restricted Mode controls administrative capabilities rather than firmware support, and Transition Mode is temporary and procedural. Only Mixed Mode meets the requirement of managing devices running different firmware versions within one administrative domain, providing both flexibility and centralized control.

Question 49 

Which FortiGate log type contains information about SSL/TLS handshakes, certificate validation, and encrypted session establishment?

A) Traffic Logs
B) Event Logs
C) Security Logs
D) VPN Logs

Answer: B) 

Explanation 

Traffic Logs are designed to capture the flow of network traffic passing through a FortiGate device. They record whether sessions are permitted or denied and include key connection-level details such as source and destination IP addresses, ports, protocols, and NAT information. These logs are valuable for monitoring network activity, identifying which devices are communicating, and troubleshooting general connectivity issues. However, Traffic Logs operate at a session level and do not provide insight into the specifics of SSL/TLS handshakes, certificate validation, or the detailed steps involved in establishing encrypted sessions. While they show that a connection occurred, they cannot explain why a secure connection might have failed or highlight issues with certificate trust or SSL inspection.

Event Logs, in contrast, focus on system-level events and provide a much deeper view into the operations of the FortiGate device. They capture critical information related to SSL/TLS negotiation, including handshake successes and failures, certificate validation results, and SSL inspection events. Event Logs are particularly useful when troubleshooting encrypted communications because they provide visibility into errors and anomalies that occur during the setup of a secure session. For instance, if a client attempts to connect to a server but the certificate is invalid or the handshake fails, Event Logs will document these events in detail, enabling administrators to identify and remediate the underlying problem.

Security Logs are primarily concerned with monitoring and recording security-related events. These include alerts from antivirus scans, intrusion prevention system (IPS) signatures, application control enforcement, or other threat detections. While Security Logs are essential for maintaining network security and detecting potential threats, they do not provide visibility into the SSL/TLS handshake process or certificate validation. Their purpose is to flag malicious or suspicious activity rather than to analyze the mechanics of encrypted session establishment, so they are not suitable for troubleshooting SSL/TLS issues.

VPN Logs track activities specific to VPN tunnels, including the establishment of secure tunnels, IKE phase exchanges, and encryption key management. They provide detailed information on how VPN connections are negotiated and maintained, but this data is focused on VPN-specific encryption. Generic SSL/TLS sessions that occur outside of VPN tunnels—such as HTTPS traffic between a client and a web server—are not captured in this level of detail in VPN Logs.

Event Logs are the correct choice because they capture detailed system events related to SSL/TLS negotiation and certificate validation, including handshake successes and failures. Traffic Logs provide connection-level information without SSL context, Security Logs focus on threat events, and VPN Logs only cover encrypted tunnels. Administrators rely on Event Logs when diagnosing issues with SSL/TLS communication because they offer the necessary visibility into handshake processes, certificate errors, and encrypted session establishment that the other log types cannot provide.

Question 50 

Which FortiGate feature is primarily responsible for maintaining active sessions during HA failover?

A) Load Balancing
B) Session Pickup
C) Virtual Domains
D) Link Health Monitor

Answer: B)

Explanation 

Load Balancing is a feature commonly used in FortiGate high availability (HA) environments to distribute network traffic across multiple devices or interfaces. Its primary purpose is to optimize throughput, reduce latency, and prevent any single device from becoming a bottleneck. By spreading the load, it improves overall performance and ensures that resources are utilized efficiently. However, Load Balancing focuses on traffic distribution and does not maintain a record of active session tables across HA units. This means that if the primary device fails, the secondary unit will not automatically know the state of existing connections. As a result, ongoing sessions, such as TCP connections or VPN tunnels, will be interrupted, leading to dropped sessions for end users.

Session Pickup addresses this limitation by synchronizing active session information between HA units. When enabled, the primary FortiGate continuously shares its session tables with the secondary device. In the event of a failover, the secondary unit can immediately take over all active sessions without forcing users to reconnect or experience service disruption. This includes long-lived TCP connections, IPsec VPN tunnels, and other persistent sessions that are critical in enterprise networks. By preserving session continuity, Session Pickup ensures that users experience minimal downtime, maintaining business operations and reducing the risk of interrupted services.

Virtual Domains (VDOMs) provide a different type of functionality. They allow a single FortiGate device to create multiple logical domains for administration and policy enforcement. VDOMs are highly valuable in multitenant environments or organizations with separate departments, as they enable policy segregation and independent management. However, VDOMs do not synchronize session tables or influence HA failover behavior. While they help organize security policies and administrative responsibilities, they do not address the continuity of active sessions during a device failover scenario.

Link Health Monitor is another HA-related feature, but its role is limited to monitoring the availability of network links. It can detect upstream or downstream failures and trigger failover events when a link goes down. While this ensures that traffic is rerouted in response to connectivity issues, Link Health Monitor does not store or synchronize session information. Without Session Pickup, failover triggered by link failures will still result in lost sessions, as the secondary device will not have knowledge of existing connections.

Session Pickup is therefore the essential HA feature for maintaining session persistence. While Load Balancing optimizes traffic distribution, Virtual Domains provide logical segmentation, and Link Health Monitor detects failures, only Session Pickup guarantees that active sessions continue seamlessly during HA failover. This capability is critical for maintaining uninterrupted network services and ensuring a reliable user experience in enterprise environments.

Question 51 

Which FortiGate feature inspects encrypted traffic without decrypting it to identify applications and enforce security policies?

A) SSL Deep Inspection
B) SSL Certificate Inspection
C) SSL Offloading
D) SSL Proxy

Answer: B) 

Explanation 

SSL Deep Inspection actively decrypts SSL/TLS traffic to inspect payloads, apply antivirus, IPS, or application control. While highly effective, it requires access to the traffic’s content, meaning the firewall must handle decryption and re-encryption. This introduces latency and necessitates certificate management. Because it decrypts traffic, it does not meet the requirement of inspecting encrypted traffic without decryption.

SSL Certificate Inspection analyzes the SSL handshake and certificate attributes such as validity, issuer, expiration, and revocation status. It does not decrypt the traffic itself but uses information in the certificate to enforce policies, such as blocking untrusted or expired certificates. This method enables identification of applications that rely on SSL/TLS without accessing the encrypted payload, making it lightweight and aligned with the requirement.

SSL Offloading refers to moving SSL processing tasks, such as encryption and decryption, from the CPU to specialized hardware to improve performance. While it can enhance throughput for encrypted traffic, it still involves decryption and does not independently identify applications without decrypting sessions.

SSL Proxy establishes a dedicated proxy session for encrypted traffic, often requiring full decryption and re-encryption to inspect the payload. It provides content inspection and application control but does not avoid decryption, so it does not satisfy the “without decrypting” criterion.

SSL Certificate Inspection is correct because it inspects handshake and certificate attributes to enforce policies and identify applications without decrypting the traffic. SSL Deep Inspection and SSL Proxy require decryption, and SSL Offloading only accelerates SSL processing rather than inspecting certificates.

Question 52 

Which FortiGate feature can dynamically classify traffic for non-standard ports or port-hopping applications?

A) Firewall Policy
B) Application Control
C) Web Filtering
D) DoS Sensor

Answer: B) 

Explanation 

Firewall Policy enforces rules based on IP addresses, ports, interfaces, and services. While it can block or allow traffic, it relies on static port numbers and cannot dynamically identify applications that use non-standard ports or hop between ports. Policies are applied at Layer 3/4, not Layer 7, so firewall rules alone cannot classify port-hopping traffic.

Application Control uses deep packet inspection, signature analysis, and behavioral patterns to identify applications regardless of the port or protocol used. This allows it to enforce policies even when applications evade detection by using non-standard ports or port-hopping techniques. It is specifically designed to dynamically classify applications for precise control.

Web Filtering categorizes traffic by URL reputation or content. While it can block certain web services or malicious URLs, it does not identify port-hopping applications outside of the HTTP/HTTPS protocol context. It is not intended for Layer 7 application classification across arbitrary ports.

DoS Sensor monitors traffic for volumetric attacks or abnormal behavior, focusing on flooding patterns rather than application identification. It does not perform deep analysis to classify applications on non-standard ports.

Application Control is correct because it inspects traffic at the application layer and identifies applications regardless of port behavior. Firewall Policies are port-dependent, Web Filtering focuses on URLs, and DoS Sensor targets floods, not application classification.

Question 53

Which FortiAnalyzer feature allows administrators to run SQL queries against logs for deep forensic analysis?

A) Log View
B) SQL Query Tool
C) Report Builder
D) Event Handler

Answer: B) 

Explanation 

Log View provides a graphical interface for inspecting logs collected from Fortinet devices. It allows administrators to search, filter, and view logs based on predefined criteria. While it is convenient for basic log review or quick checks, Log View does not enable advanced querying or cross-referencing of multiple datasets. Its purpose is primarily general visibility rather than in-depth forensic analysis.

The SQL Query Tool allows direct access to the FortiAnalyzer database using SQL commands. Administrators can construct complex queries to correlate multiple events, extract patterns, and identify anomalies that standard reports cannot reveal. This feature is particularly useful for forensic investigations where detailed analysis of log data across multiple tables is required. It provides flexibility to explore relationships and trends in security events that are not available through predefined reports or graphical views.

Report Builder is designed to create structured, scheduled, or ad hoc reports based on templates. Administrators can generate summaries of network activity, security events, or compliance metrics. However, it does not provide direct SQL access to the underlying database. While useful for reporting, it is not suitable for forensic-level analysis or custom querying of raw log data.

Event Handler enables automation by triggering actions based on predefined event conditions, such as sending alerts, executing scripts, or notifying administrators. It does not provide interactive querying or database access. Its focus is on response automation rather than investigation. The SQL Query Tool is the correct choice because it offers direct querying of the FortiAnalyzer database, allowing deep forensic analysis, while the other options focus on viewing, reporting, or automated response.

Question 54 

Which FortiGate feature is used to transparently inspect traffic between two interfaces without requiring IP addressing?

A) Virtual Wire Pair
B) VLAN Interface
C) Policy Route
D) Proxy ARP

Answer: A) 

Explanation 

Virtual Wire Pair enables FortiGate devices to act as a transparent bridge between two interfaces at Layer 2. Traffic flows through the FortiGate without the need for IP addressing or routing. This makes it ideal for inline security inspection in networks where topology changes are undesirable or where IP configurations cannot be applied. It allows full application of security policies while remaining invisible to the network.

VLAN Interface assigns Layer 3 IP addresses to a VLAN segment and is used for routing between VLANs or subnets. While VLAN Interfaces allow enforcement of policies and routing, they are not transparent; they require IP configuration. Traffic passing through a VLAN Interface is not automatically bridged, so it cannot provide inspection without IP addressing.

Policy Route directs traffic based on criteria like source, destination, or service. It is a Layer 3 function, meaning it depends on IP addresses for routing decisions. While useful for traffic management and selective routing, it does not allow transparent inspection between interfaces because all traffic decisions are based on Layer 3 attributes.

Proxy ARP responds to ARP requests on behalf of other devices, allowing devices to appear reachable at different IP addresses. While it helps with address resolution in routed networks, it does not perform traffic inspection or bridging. Virtual Wire Pair is correct because it allows transparent inspection between interfaces without requiring IP addresses, whereas VLAN Interface, Policy Route, and Proxy ARP do not provide this capability.

Question 55 

Which FortiGate feature allows automatic policy adjustment based on endpoint risk or posture?

A) DoS Sensor
B) Dynamic Policy
C) NP6 Offload
D) Web Filtering

Answer: B) 

Explanation 

DoS Sensor is designed to detect and mitigate flooding attacks or abnormal traffic patterns. Its primary goal is to protect network resources from denial-of-service attacks. While it is an important security feature, it does not adjust policies dynamically based on the risk profile or posture of endpoints. Its function is reactive and threat-focused rather than adaptive to user or device attributes.

Dynamic Policy enables automatic adjustment of security policies according to the risk level, device type, or user role. It leverages data from Security Fabric components such as EMS or FortiNAC to make real-time policy decisions. For example, devices with low security posture may be restricted or quarantined, while trusted devices can access more resources. This provides adaptive enforcement and aligns with zero-trust security principles, making it highly effective for environments where endpoint posture is variable.

NP6 Offload is a hardware acceleration feature that offloads traffic processing to dedicated network processors. Its purpose is to improve throughput and performance for high-volume traffic. NP6 Offload does not have any mechanism to modify policies based on endpoint attributes or security posture, as it focuses purely on performance optimization.

Web Filtering inspects URLs and web content to block access to malicious or inappropriate sites. While it enforces content-based policies, it does not dynamically adjust security policies based on the risk or posture of endpoints. Dynamic Policy is correct because it automatically modifies access rules and security policies in response to endpoint attributes, whereas the other features focus on attack mitigation, performance, or URL filtering.

Question 56 

Which FortiGate log type shows detailed SSL handshake, certificate, and encrypted session events?

A) Traffic Logs
B) Event Logs
C) Security Logs
D) VPN Logs

Answer: B) 

Explanation 

Traffic Logs are designed to provide information about connections passing through the FortiGate device. They typically include details such as source and destination IP addresses, source and destination ports, the protocol used, NAT translations, and session duration. These logs are very useful for monitoring general network traffic, identifying bandwidth usage, and troubleshooting connectivity issues. However, they do not provide information about SSL/TLS handshakes or certificate validations. Therefore, while Traffic Logs are useful for understanding overall session flows, they lack the granularity needed for analyzing encrypted sessions.

Event Logs capture system-level activities and changes within the FortiGate device. These logs include details about system events, configuration changes, SSL/TLS handshake failures, certificate errors, and SSL inspection events. Event Logs are particularly useful for administrators who need to troubleshoot encrypted session establishment or verify certificate validation. This log type records detailed information about what occurs during the SSL handshake process and any errors that may arise, making it the most appropriate source for analyzing SSL and encrypted session events.

Security Logs focus on the detection and recording of threat-related events. This includes antivirus detections, intrusion prevention system (IPS) events, web filtering blocks, and other threat-related activities. While these logs are essential for security monitoring, they do not provide visibility into the SSL/TLS handshake or certificate validation. Their primary role is to identify and document security threats rather than track encrypted session establishment.

VPN Logs document activities related to VPN connections, including tunnel establishment, IKE phase progress, and encryption key exchanges. These logs are crucial for troubleshooting VPN connections, monitoring VPN uptime, and ensuring secure tunnel configuration. However, VPN Logs do not provide comprehensive details about general SSL/TLS sessions that occur outside of VPN tunnels. Therefore, the correct choice is Event Logs, as they provide the necessary insight into SSL handshake processes, certificate validation, and encrypted session details.

Question 57

Which FortiGate feature prevents lateral movement by dynamically isolating devices based on tags or risk?

A) Traffic Shaping
B) VLAN Pooling
C) Fabric-based Segmentation
D) MAC-based Policy

Answer: C)

Explanation 

Traffic Shaping is a feature primarily focused on controlling bandwidth allocation and prioritizing certain types of traffic. It allows administrators to ensure critical applications receive sufficient bandwidth while limiting less important traffic. Although it improves network performance and user experience, Traffic Shaping does not have the ability to isolate devices dynamically based on security risk or device tags. Its scope is entirely performance-oriented rather than security-driven.

VLAN Pooling is used to distribute devices across multiple VLANs to balance network load. This helps avoid congestion on a single VLAN by assigning devices dynamically to different VLANs, but the assignment is not based on security posture or risk. VLAN Pooling does not prevent lateral movement of potentially compromised devices because it does not dynamically respond to security threats. Its primary function is traffic management rather than risk mitigation.

Fabric-based Segmentation is designed specifically to enforce security segmentation in a dynamic manner. It leverages tags from Fortinet Security Fabric components, such as EMS, FortiNAC, or other integrated systems, to identify devices based on risk, compliance status, or other criteria. Devices that are deemed risky or untrusted can be automatically isolated into a separate segment, preventing lateral movement across the network. This zero-trust approach ensures that even if a device is compromised, it cannot easily infect or communicate with other sensitive systems.

MAC-based Policy allows administrators to apply rules based on the MAC addresses of devices. While it can restrict network access and enforce simple security policies, MAC-based Policies are static and require manual configuration. They do not dynamically adjust based on tags or device risk levels, making them less effective in environments where security posture changes frequently. Fabric-based Segmentation is the correct option because it dynamically isolates devices based on risk, effectively preventing lateral movement while other options focus on performance, load balancing, or static controls.

Question 58 

Which FortiGate HA feature ensures active sessions persist when the primary unit fails?

A) Load Balancing
B) Session Pickup
C) Virtual Domains
D) Link Health Monitor

Answer: B) 

Explanation 

Load Balancing is a method used to distribute network traffic across multiple devices to improve performance and prevent any single device from being overwhelmed. While it effectively manages traffic loads, it does not maintain session continuity during a failover. If an HA primary unit fails, the sessions being processed by that unit would be lost without a mechanism to synchronize them to the secondary device.

Session Pickup is specifically designed to preserve active sessions during HA failover. This feature allows the secondary HA unit to take over without disrupting ongoing TCP connections, VPN sessions, or other long-lived flows. By synchronizing session state between primary and secondary units, Session Pickup ensures seamless continuity for users, preventing dropped connections and avoiding the need for users to reconnect. This feature is crucial in environments where uninterrupted access is required for business-critical applications.

Virtual Domains (VDOMs) allow a FortiGate device to create multiple virtual firewalls within a single physical unit. VDOMs provide administrative and policy separation between different departments, customers, or network segments. However, VDOMs do not synchronize session information between HA units and therefore cannot prevent session drops during a failover. Their role is more focused on multi-tenancy and organizational separation rather than session persistence.

Link Health Monitor detects failures in network links and can trigger failover events based on link status. Although it helps HA units respond quickly to physical link failures, it does not maintain session information across the HA cluster. Sessions will still drop if there is no Session Pickup configured. Therefore, Session Pickup is the correct answer because it directly addresses the need to preserve active sessions when the primary unit fails.

Question 59 

Which FortiGate feature is used to identify IoT devices automatically on the network?

A) MAC-based Policies
B) Device Identification
C) SD-WAN Rules
D) Route-based IPsec

Answer: B) 

Explanation 

MAC-based Policies control network access by filtering devices based on their MAC addresses. While this allows administrators to grant or restrict access to specific devices, it is not capable of automatically identifying device types or classifying them as IoT, servers, or workstations. MAC-based Policies require manual configuration for each device, making them unsuitable for dynamic IoT environments.

Device Identification, on the other hand, is a feature designed to detect and classify devices automatically. FortiGate can analyze DHCP fingerprints, traffic patterns, OS signatures, and behavioral attributes to recognize a wide range of devices, including IoT devices like cameras, sensors, and smart appliances. This allows administrators to apply appropriate security policies and segmentation without manually mapping every device, simplifying management in large or complex networks.

SD-WAN Rules are intended to optimize traffic routing and select the best network paths based on performance metrics such as latency, jitter, or packet loss. While SD-WAN enhances network performance and reliability, it does not perform device discovery or classification. Its focus is on traffic management rather than security or device identification.

Route-based IPsec establishes VPN tunnels between sites or endpoints using routing-based mechanisms. It is used to create secure communications channels over public or untrusted networks but does not provide any visibility into devices on the local network. Therefore, Device Identification is the correct option because it automatically discovers and classifies IoT devices, whereas the other options are focused on network access, routing, or VPN connectivity.

Question 60 

Which inspection mode buffers the entire file for deeper security analysis, increasing latency?

A) Flow-based Inspection
B) Proxy-based Inspection
C) IPS Offloading
D) NAT Policy

Answer: B) 

Explanation

Flow-based Inspection processes packets as they arrive in real-time, analyzing traffic on the fly. This approach provides very low latency and is suitable for high-speed environments where performance is critical. However, because Flow-based Inspection does not buffer the entire object or file, it cannot perform deep scanning of the complete content. It is effective for lightweight inspection but limited for thorough threat detection.

Proxy-based Inspection, in contrast, buffers the entire file or object before performing security analysis. This allows FortiGate to conduct comprehensive inspections, including antivirus scans, IPS analysis, and content filtering. By waiting until the entire object is received, Proxy-based Inspection can detect threats that may be hidden in later parts of the file. While this provides a higher level of security, it also increases latency because the file must be fully received before processing can complete.

IPS Offloading leverages specialized hardware to accelerate intrusion prevention scanning. While this can increase throughput and reduce CPU load, it does not buffer entire files for deep inspection. IPS Offloading is focused on speeding up packet inspection rather than enabling complete content analysis of large files.

NAT Policy controls the translation of IP addresses and ports for traffic traversing the FortiGate device. Its purpose is to enable communication between different IP segments or to hide internal network addresses behind public IPs. NAT Policy does not involve inspection of file content and cannot provide deep security analysis. Therefore, Proxy-based Inspection is the correct choice because it allows buffering of the entire file for comprehensive scanning, while the other options focus on performance optimization or traffic translation.
