Question 21 

A FortiGate administrator sees that Applications are not being detected on a newly created interface despite enabling Application Control. What should the engineer check first?

A) Whether the interface is included in a security policy using Application Control
B) Whether the FortiGate hostname is correct
C) Whether IPv6 is enabled globally
D) Whether the admin password was recently changed

Answer: A)

Explanation 

A) Whether the interface is included in a security policy using Application Control — Application Control only works when traffic enters a policy that has the Application Control profile assigned. Even if Application Control is enabled globally or at a profile level, it does not analyze traffic on an interface unless the related security policy specifically includes the inspection profile. Therefore, verifying that a security policy referencing the new interface includes the Application Control profile is the most essential and immediate check. If the profile is not associated with the policy, no application signatures will be triggered, and the traffic will appear unclassified in logs.

B) Whether the FortiGate hostname is correct — The hostname has no effect on Application Control or any traffic inspection process. Changing or verifying the hostname does not alter DPI behavior, policy enforcement, or signature recognition. A hostname matters only for administrative clarity or identifying devices in logs, not for application inspection.

C) Whether IPv6 is enabled globally — Application Control works independently for both IPv4 and IPv6, but global IPv6 activation does not influence whether application signatures trigger. If Application Control is active on a policy, it will inspect packets regardless of IPv6 status unless IPv6 traffic is excluded from the policy. Therefore, enabling or disabling IPv6 globally does not solve missing Application Control detection.

D) Whether the admin password was recently changed — Changing the admin password affects only administrative authentication and does not have any connection to deep packet inspection processes. Application Control will function normally regardless of password changes, so checking this setting would be irrelevant to the problem described.

Reasoning about the correct answer — Application Control only inspects traffic that passes through a policy configured with the Application Control profile. If the interface is newly added or reordered, the policy using that interface might not include any Application Control profile. Therefore, confirming that the correct policy includes the Application Control profile is the most direct and relevant action when applications are not being detected.

Question 22 

A FortiGate administrator finds that DNS requests sent through a specific VLAN interface are bypassing DNS Filter profiles and going directly to an external DNS server. What should be verified first?

A) That the policy for the VLAN interface has DNS Filter enabled
B) That the FortiGate system time is synchronized with NTP
C) That the HA override mode is active
D) That the FortiGate has a valid SSL certificate installed

Answer: A)

Explanation

A) That the policy for the VLAN interface has DNS Filter enabled — DNS Filter only inspects DNS traffic on policies where the DNS Filter profile is explicitly applied. If traffic leaves the VLAN interface through a policy that does not contain the DNS Filter profile, the FortiGate will forward the DNS packets without categorizing or inspecting them. This results in DNS traffic bypassing security controls entirely. Therefore, verifying that the security policy for this specific VLAN interface has DNS Filter enabled is the most important first step.

B) That the FortiGate system time is synchronized with NTP — System time accuracy is crucial for logs, certificate validation, and some security features, but incorrect time does not cause DNS Filter to be bypassed. Even with incorrect time, the DNS filter would still attempt to inspect DNS queries if the profile is correctly applied.

C) That the HA override mode is active — HA override mode influences how primary units are selected in an HA cluster but has no relationship with DNS inspection on individual interfaces. Whether override mode is active does not affect DNS filtering functionality.

D) That the FortiGate has a valid SSL certificate installed — SSL certificates are used for HTTPS deep inspection and administrative access but do not change DNS Filter behavior. DNS filtering applies to port 53 or encrypted DNS (when configured) and does not rely on SSL certificates.

Reasoning about the correct answer — DNS filtering is policy-driven. The FortiGate will not intercept DNS queries unless the policy has DNS Filter enabled. When DNS queries appear to bypass DNS filtering and go straight to an external resolver, the most logical cause is that the DNS Filter profile is missing from the active policy. Therefore, verifying the correct policy configuration is the essential first step.

Question 23

 A FortiGate running advanced threat protection is failing to block known malicious URLs. The Web Filter logs show “rating in progress” repeatedly. What should the engineer check first?

A) That FortiGate can reach FortiGuard rating servers
B) That WAN link load-balancing is disabled
C) That SSL VPN portal customization is removed
D) That the static DNS entries are cleared

Answer: A)

Explanation 

A) That FortiGate can reach FortiGuard rating servers — When the Web Filter displays “rating in progress,” it indicates the FortiGate is unable to receive a category response from FortiGuard servers. If communication is blocked, delayed, or failing, the FortiGate cannot classify URLs, which results in inconsistent or missing enforcement of URL categories. Ensuring that FortiGate can resolve, reach, and communicate with FortiGuard rating servers is therefore the first and most critical diagnostic step. This includes checking DNS resolution, routing, firewall rules, and connectivity tests.

B) That WAN link load-balancing is disabled — Load balancing across WAN interfaces does not inherently block URL categorization. Even if WAN load-balancing is enabled, the FortiGate can still reach FortiGuard servers as long as routing is correct. Disabling WAN load balancing would not reliably resolve rating issues.

C) That SSL VPN portal customization is removed — Portal customization affects how users see the SSL VPN portal and does not have any connection to URL rating or FortiGuard communication. Customization can be active without affecting web categorization.

D) That the static DNS entries are cleared — Static DNS entries could potentially override DNS lookups, but they do not inherently cause “rating in progress.” The condition almost always indicates FortiGuard connectivity failure rather than DNS override misconfigurations.

Reasoning about the correct answer — URL categorization requires successful real-time communication with FortiGuard. The phrase “rating in progress” is a direct symptom of connectivity loss or lookup failure. Therefore, verifying connectivity to rating servers is the most logical and correct first action.

Question 24 

A FortiGate administrator finds that TCP sessions are being dropped after 10 minutes, even though the policy idle-timeout is set to 1 hour. What should be checked first?

A) The session TTL configured in the global system settings
B) The NTP polling interval
C) Whether FortiAnalyzer logging is enabled
D) Whether GUI HTTPS redirect is turned on

Answer: A)

Explanation 

A) The session TTL configured in the global system settings — TCP session lifetime depends on multiple parameters, including policy idle-timeout and system-wide session TTL. If the global session TTL value is set lower than the policy timeout, the FortiGate will drop sessions earlier than expected, even if the policy specifies a longer timeout. Session TTL determines how long a session may exist regardless of activity. Therefore, verifying whether the system-wide session TTL is set appropriately is the correct first diagnostic step when sessions close prematurely.

B) The NTP polling interval — NTP synchronization influences system time accuracy but does not cause session drops. Incorrect NTP settings would not shorten session lifetimes or force session closures.

C) Whether FortiAnalyzer logging is enabled — Whether logs are uploaded to FortiAnalyzer does not influence session timers. Log settings have no authority over session expiration behavior.

D) Whether GUI HTTPS redirection is turned on — This setting affects administrative access redirection only and has no connection to session timeout or session TTL.

Reasoning about the correct answer — When sessions close earlier than the policy idle-timeout specifies, the global session TTL is often overriding the policy. Confirming session TTL is therefore the logical and correct first check.

Question 25 

A FortiGate administrator notices that a new explicit proxy policy is not matching traffic. The proxy port is configured correctly, and clients are pointing to the FortiGate. What should be checked first?

A) Whether the source interface in the policy matches the interface receiving proxy traffic
B) Whether port forwarding is enabled on the WAN interface
C) Whether antivirus license is expired
D) Whether the FortiGate has a loopback interface created

Answer: A)

Explanation 

A) Whether the source interface in the policy matches the interface receiving proxy traffic — Explicit proxy policies match based on source interface, destination criteria, and service. If the source interface does not match the interface where proxy requests are arriving, the policy will never trigger. This is one of the most common configuration issues with explicit proxying. If clients connect to the proxy on interface X but the policy is configured with interface Y, traffic flows will remain unclassified and no inspection will occur. Therefore, verifying the correct source interface is the essential first step.

B) Whether port forwarding is enabled on the WAN interface — Port forwarding affects inbound NAT behavior and external access but has no connection to internal client proxy requests. Explicit proxy is typically accessed through internal or LAN interfaces, not WAN port forwarding.

C) Whether antivirus license is expired — Antivirus licensing does not change proxy policy matching. Even without an AV license, proxy matching continues to work; only AV inspection would be impacted.

D) Whether the FortiGate has a loopback interface created — Loopback interfaces are used for routing and specific advanced configurations but are not required for explicit proxy operation. The absence of a loopback interface does not prevent proxy policy matching.

Reasoning about the correct answer — Proxy traffic must enter through an interface that matches the explicit proxy policy’s source interface. If these do not align, the policy never applies. Therefore, verifying that the correct source interface is defined is the most direct and necessary first step.

Question 26 

Which FortiGate feature is responsible for automatically adjusting security policies based on detected device types and risk profiles?

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

Answer: B)

Explanation 

Web Filtering inspects and categorizes web traffic and URLs to enforce access restrictions or block malicious content. While it is an important security layer, it does not monitor device behavior or adapt policies based on changing risk levels. It focuses on content inspection and category-based restrictions, rather than the profiling or classification of endpoints. Because its function is URL-based enforcement, it has no involvement in dynamically modifying security rules that govern broader network access.

Dynamic Policy is designed to modify security rules automatically when endpoint attributes change. This includes reacting to device classification, risk level, user identity, or tags coming from FortiNAC, EMS, or other fabric components. It enables administrators to create policies that automatically adapt, eliminating the need for manual rule adjustments. In environments with many devices or constant profile changes, this feature ensures that the correct policy is always applied without human intervention. This behavior aligns directly with the ability to adjust based on device posture and risk assessments.

DoS Sensor protects FortiGate from denial-of-service attacks by monitoring traffic behavior and preventing floods, malformed packets, and resource-exhaustion attempts. Although it reacts dynamically to suspicious traffic patterns, it does not adapt security rules based on endpoint device identity or posture. Its purpose is purely to safeguard system resources and protect service availability rather than modify policy behavior across sessions.

NP6 Offloading accelerates traffic by pushing processing tasks to hardware network processors. It focuses entirely on performance optimization rather than security posture adaptation. While extremely valuable in high-throughput environments, an NP chip has no capability to alter policies in response to device profiles, risk scores, or tag changes. Its function is limited to processing packets more efficiently and supporting features such as VPN offload and fast-path handling.

Dynamic Policy is the correct answer because it is the only feature explicitly designed to adjust security rules based on changing device posture, user identity, or fabric-generated tags. This mechanism is fundamental in zero-trust and adaptive security models, where user or device conditions may shift frequently. Web Filtering focuses on content; DoS Sensor protects against floods; NP6 Offloading improves performance. Only Dynamic Policy links endpoint behavior to automatic policy enforcement changes, fulfilling the requirement of adapting rules based on device type and risk profile.

Question 27

In FortiManager, which ADOM mode allows administrators to manage devices running different firmware versions within the same ADOM?

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

Answer: B)

Explanation 

Normal Mode is the default and enforces strict version consistency within a single ADOM. In this mode, all devices assigned to the same ADOM must run the same major FortiOS version. If a device is on a different version, it cannot be added until the firmware is adjusted to match. This strict structure ensures predictable policy behavior but does not support environments with varied software versions. Because of this limitation, it does not allow management of mixed-version devices.

Mixed Mode specifically allows different firmware versions to coexist within the same ADOM. This mode removes the strict version enforcement of Normal Mode and provides flexibility for environments in which devices cannot be upgraded immediately. Administrators can maintain a single management domain even if FortiGates run on different major or minor versions. This mode is particularly useful during phased upgrade cycles or when organizations manage diverse deployments. It directly answers the requirement of supporting multiple firmware versions under one ADOM.

Restricted Mode applies permission constraints and operational limits but does not change firmware version rules. Its purpose is to restrict what administrators can modify or control, usually for compliance or role-based access scenarios. It does not address firmware compatibility or multi-version management. Because it modifies access rather than firmware handling behavior, it cannot meet the requirement of managing a mix of different FortiOS versions within the same ADOM.

Transition Mode is temporary and used when converting ADOMs between modes or performing system migrations. It is not intended to be a permanent management state and does not define behavior for mixed firmware. Instead, it is simply an intermediate configuration used during structural changes. Therefore, it cannot be used as a standard operational mode to manage various firmware versions across devices within the same ADOM.

Mixed Mode is the correct answer because it is explicitly designed to allow multiple firmware versions in one ADOM. Normal Mode prohibits mixed versions; Restricted Mode governs permissions; Transition Mode is temporary and not designed for ongoing management. Only Mixed Mode satisfies the requirement to manage different firmware versions together within a single administrative domain.

Question 28 

Which FortiGate log type provides details about SSL/TLS negotiation, certificate validation, and encrypted session establishment?

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

Answer: B)

Explanation 

Traffic Logs record permitted or denied session flows, showing source, destination, NAT details, bandwidth usage, and session durations. They help administrators understand which connections are passing or being blocked, but they do not track the specific processes related to certificate validation or TLS handshake events. Although encrypted traffic may appear in Traffic Logs, the negotiation details themselves are not included, so this log type cannot fulfill the requirement of showing SSL/TLS establishment information.

Event Logs capture system-level occurrences, including SSL/TLS negotiation failures, certificate issues, handshake errors, and alerts related to encryption processes. These logs record when certificates are invalid, expired, mismatched, or untrusted. They also log events such as failed TLS handshakes or SSL inspection errors. Because they document the details surrounding the creation of encrypted sessions from a system perspective, Event Logs are the correct category for analyzing certificate validation and negotiation issues.

Security Logs focus on detection events triggered by security profiles such as antivirus, intrusion prevention, web filtering, and application control. Although SSL inspection can indirectly influence some security events, the logs generated here relate to threat detection rather than certificate validation or handshake mechanics. Security Logs may record detections occurring inside decryptable sessions but not the process of establishing the encrypted channel itself.

VPN Logs record tunnel negotiations, IKE exchanges, phase 1 and 2 configurations, and remote gateway interactions in IPsec or SSL VPN contexts. While these logs include encryption-related details, they pertain to VPN tunnels and not general SSL/TLS certificate validation for normal traffic inspection. VPN Logs should not be confused with generic SSL/TLS handshake logs, as their focus is solely on VPN-specific security associations, keys, and tunnel states.

Event Logs are the correct answer because they contain the detailed system messages related to SSL/TLS negotiation, certificate problems, and the establishment of encrypted sessions. Traffic Logs show connection data but not certificate-handshake details. Security Logs relate to threat detection. VPN Logs are for tunnel setup, not general SSL/TLS validation. Only Event Logs provide the specific information needed to diagnose SSL/TLS handshake and certificate verification issues.

Question 29 

What is the primary purpose of using Virtual Wire Pair on a FortiGate?

A) To create routed links between VLANs
B) To transparently inspect traffic between two interfaces
C) To prioritize traffic using QoS rules
D) To establish an L2 VPN tunnel

Answer: B)

Explanation 

Creating routed links between VLANs requires routing or inter-VLAN policies, which Virtual Wire Pair does not provide. Routed connections involve IP addressing, gateways, and routing tables, whereas Virtual Wire Pair establishes a transparent connection without participating in routing. Because it lacks IP addressing or routing capability, it cannot create routed links between VLANs. Its design is specifically to avoid routing complexity.

Transparent inspection between two interfaces is the primary purpose of Virtual Wire Pair. When two interfaces are paired, traffic flows through as if the FortiGate were an inline bridge. No IP addressing or routing is required, and FortiGate can inspect traffic at Layer 2. Administrators use this to insert FortiGate between devices or segments without redesigning network topology. All security profiles, policy enforcement, and inspection can be applied while maintaining full transparency. This ability matches exactly with the operational goal of Virtual Wire Pair.

Prioritizing traffic using QoS involves shaping policies, priority rules, and bandwidth allocation, none of which require a Virtual Wire Pair. While QoS can be applied to policies within a VWP environment, the feature itself is not designed for prioritizing traffic. QoS functions are independent and do not rely on a Virtual Wire Pair being configured. Therefore, this does not represent the primary purpose of VWP.

Establishing an L2 VPN tunnel requires technologies such as Ethernet over IP or dedicated tunneling protocols. Virtual Wire Pair is not a tunneling mechanism and does not encapsulate traffic. It simply bridges packets transparently between two physical or virtual interfaces. It does not create VPN tunnels nor does it extend Layer 2 across remote sites. Because no tunneling, encapsulation, or remote extension occurs, L2 VPN formation is not part of VWP functionality.

Virtual Wire Pair’s primary purpose is transparent inline inspection. It allows administrators to place a FortiGate between two devices or networks without requiring addressing changes, routing adjustments, or topology redesign. The feature is ideal for environments needing Layer 2 transparent filtering or where a quick inline deployment is needed. The other choices focus on routing, QoS, or VPN technologies, none of which align with the core design of Virtual Wire Pair.

Question 30

In FortiAnalyzer, what is the main function of the SQL Query Tool?

A) To perform system diagnostics
B) To manually search and filter log data
C) To configure device log quotas
D) To generate encryption keys

Answer: B)

Explanation 

System diagnostics involve checking hardware status, performance metrics, and process activity. FortiAnalyzer includes diagnostics tools such as system performance monitors and CLI diagnostic commands. However, these are separate from the SQL Query Tool. Diagnostics do not involve querying database tables or generating custom log searches. Therefore, the SQL Query Tool is not used for performing system diagnostics and cannot fulfill this function.

Manually searching and filtering log data is the primary purpose of the SQL Query Tool. It allows administrators to craft detailed SQL queries against the FortiAnalyzer logging database. This capability enables advanced filtering beyond what predefined reports or simple search filters offer. Administrators can perform deep investigations, correlate events, extract specific session patterns, and analyze logs with full SQL granularity. The SQL Query Tool is designed for this purpose and provides direct access to log tables, making it the correct answer.

Configuring device log quotas involves setting storage limits for logs coming from various devices. This ensures that storage capacity is managed properly, and devices do not exceed their allocated space. Log quotas are configured within device settings or storage management areas, not within the SQL Query Tool. Therefore, log quota configuration is unrelated to SQL querying and cannot be accomplished with this tool.

Generating encryption keys is a cryptographic operation used for securing communication or storage. FortiAnalyzer does not rely on the SQL Query Tool to generate such keys. Key generation occurs through dedicated security processes and system-level encryption settings. The SQL Query Tool cannot perform cryptographic tasks because it is built solely for database search and log analysis. Thus, key generation is not part of its function.

The SQL Query Tool is the correct answer because its primary purpose is to enable manual, granular searching of log data using SQL syntax. It supplements built-in reporting and helps support engineers investigate complex scenarios where standard filters are insufficient. The other choices describe functions unrelated to database querying: system diagnostics, storage quota configuration, and cryptographic operations. Only the SQL Query Tool provides direct access to structured log data for detailed analysis.

Question 31 

Which FortiGate feature ensures that sessions associated with a failed HA primary unit continue without interruption when a secondary unit takes over?

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

Answer: B)

Explanation 

Load Balancing distributes traffic across multiple devices or links to optimize throughput or redundancy. While this can improve network resilience and performance, it does not preserve active session tables during an HA failover. Load Balancing does not synchronize session information between HA members, so ongoing sessions may still be reset if a failover occurs. Its function focuses on resource distribution rather than session continuity.

Session Pickup is responsible for maintaining active sessions when an HA failover occurs. It synchronizes session tables between HA units, ensuring the secondary device can continue processing existing sessions without interruption. This prevents disruptions to established connections such as voice calls, VPN tunnels, downloads, and large data transfers. Because it relies on real-time synchronization of NAT translations, TCP state, and other session attributes, it is the only feature that directly addresses uninterrupted session continuity during a failover event.

Virtual Domains provide logical segmentation inside a FortiGate, allowing multiple independent security domains and administrative environments. While this is valuable for MSPs and enterprises needing multitenancy or network separation, it has no influence on HA session preservation. VDOMs do not manage or synchronize session tables; they simply isolate administrative and policy control. Therefore, they do not ensure continued operation of ongoing sessions during failover.

Link Health Monitor checks the availability of upstream or downstream network paths by sending probes to gateways, servers, or IP addresses. If a monitored link fails, the FortiGate can reroute or trigger failover events. However, while link monitoring can initiate an HA transition, it does not handle the continuity of session states. Its role is detection, not session preservation. Thus, it does not serve the mechanism required for uninterrupted session handling.

Session Pickup is the correct answer because it is the specific mechanism designed to synchronize session information between HA units so that existing sessions persist seamlessly after failover. Load Balancing improves distribution but does not maintain session state. Virtual Domains create logical separation but offer no failover benefits related to active sessions. Link Health Monitor detects link failures but does not preserve session information. Only Session Pickup directly guarantees continuity of active traffic after an HA role switch.

Question 32 

Which FortiGate feature allows the firewall to classify applications even when they use non-standard ports?

A) Static Routing
B) Application Control
C) Traffic Shaping
D) Local-in Policies

Answer: B)

Explanation 

Static Routing defines predictable paths for traffic based on destination IP addresses. It ensures that packets are forwarded efficiently according to the routing table. While essential for network connectivity, routing does not provide visibility into the type of application being used. Routing decisions are based on Layer 3 information, not application signatures or traffic behavior. As a result, Static Routing cannot classify applications or inspect traffic on unusual ports.

Application Control identifies and classifies applications using deep inspection techniques such as pattern matching, heuristics, and flow analysis. It can detect applications regardless of port or protocol, which is crucial because many modern applications use port hopping, tunneling, or encryption. Application Control analyzes payloads and behavioral characteristics instead of relying on ports. This gives FortiGate the ability to enforce policies based on application identity, making it the correct answer for classification on non-standard ports.

Traffic Shaping manages bandwidth allocation, prioritization, and rate control. While shaping policies can reference application categories when combined with Application Control, shaping itself does not classify applications. It relies on classification being performed elsewhere. Traffic Shaping primarily influences throughput rather than identifying application characteristics. It cannot independently classify traffic using unusual ports.

Local-in Policies govern traffic destined for the firewall’s own IP addresses and services such as administrative access, VPN services, and routing protocols. These policies protect the control plane and manage inbound traffic to the FortiGate itself. They do not inspect or classify forwarded traffic passing through the firewall. Their purpose is security of the device rather than traffic classification.

Application Control is the correct answer because it is the feature specifically designed to recognize applications independent of port or protocol. Static Routing manages forwarding decisions, Traffic Shaping controls bandwidth but cannot classify traffic, and Local-in Policies protect firewall-bound services. Only Application Control analyzes Layer 7 characteristics deeply enough to identify applications using non-standard ports.

Question 33

Which component of the Fortinet Security Fabric is primarily responsible for sharing endpoint telemetry, vulnerability data, and risk scores?

A) FortiSwitch
B) FortiAP
C) FortiAnalyzer
D) FortiClient EMS

Answer: D)

Explanation 

FortiSwitch provides network switching functionality, including VLAN segmentation, NAC enforcement through FortiLink, and traffic forwarding. While FortiSwitch can participate in the Security Fabric, it does not collect or distribute endpoint-specific telemetry such as vulnerabilities, application behavior, or risk-level scoring. Its focus is networking rather than detailed host telemetry. Therefore, it cannot fulfill the requirement of sharing endpoint posture information.

FortiAP provides wireless connectivity and integrates with FortiGate for control and security functions. Although it supports device classification at the Wi-Fi access layer, FortiAP does not gather in-depth endpoint telemetry such as vulnerabilities or risk scores. Its main purpose is wireless access rather than telemetry distribution. This makes it unsuitable as the primary component responsible for sharing detailed endpoint data across the Security Fabric.

FortiAnalyzer collects logs from multiple Fortinet devices and provides reporting, analytics, event correlation, and forensic capabilities. While it can analyze endpoint-related logs, it does not actively manage endpoint agents or assign risk scores. It is not responsible for distributing telemetry across the Security Fabric. Instead, it acts as a logging and reporting backend. Therefore, it is not the correct answer for managing or sharing real-time endpoint telemetry.

FortiClient EMS manages endpoint agents, collects host telemetry, evaluates vulnerabilities, assigns risk scores, and shares this information with the Security Fabric. It monitors applications, patch levels, running processes, compliance posture, and other detailed endpoint attributes. EMS communicates this data to FortiGate and other fabric members, enabling dynamic policies and zero-trust access decisions. Because it is the central controller for FortiClient endpoints and the authoritative source of endpoint posture, it is the correct answer.

FortiClient EMS is therefore the component responsible for gathering and distributing endpoint telemetry, vulnerability details, and risk scoring throughout the Security Fabric. The other choices either provide network access or analytics but do not manage endpoint agents or generate posture information. Only EMS serves this specific role.

Question 34 

Which FortiOS feature enables the automatic discovery and classification of IoT devices on the network?

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

Answer: B)

Explanation 

MAC-based Policies use the MAC address of a device to determine access rights or apply specific firewall rules. While useful in environments where identity or IP addressing is inconsistent, this method requires administrators to manually specify MAC addresses. It does not automatically discover or classify devices. MAC-based Policies cannot determine device type, category, OS, or role, making them unsuitable for IoT discovery.

Device Identification automatically detects and categorizes devices connecting to the network, including IoT devices. It uses DHCP signatures, traffic fingerprints, OS patterns, and other behavioral indicators to recognize device types. This allows FortiGate to classify endpoints as printers, cameras, sensors, PLCs, or other IoT categories without manual input. Because this feature is specifically designed for automatic discovery and classification, it is the correct answer.

Route-based IPsec creates VPN tunnels that operate as routed interfaces. These tunnels are used for secure communication between networks but do not detect or classify devices. IPsec is focused on encryption and routing behavior, not on device identification or IoT posture analysis. Therefore, it cannot meet the requirement described in the question.

SD-WAN Rules optimize traffic flow by selecting the best available link based on performance metrics, application type, or routing conditions. While SD-WAN integrates with several fabric components, it does not perform device discovery or classification. Its purpose is traffic management rather than asset identification. As such, SD-WAN Rules do not fulfill the functionality needed for IoT visibility.

Device Identification is the correct answer because it is designed to automatically detect, profile, and categorize devices joining the network. MAC-based Policies require manual entry, Route-based IPsec deals with tunneling, and SD-WAN Rules manage traffic paths. Only Device Identification provides dynamic automatic classification of IoT devices.

Question 35 

Which type of FortiGate policy is evaluated first when traffic arrives at the firewall?

A) IPv4 Policy
B) Local-in Policy
C) DoS Policy
D) Proxy Policy

Answer: B)

Explanation 

IPv4 Policy governs traffic that is forwarded through the firewall from one interface to another. These policies handle decisions such as allowing, denying, applying NAT, and triggering security profiles. However, IPv4 Policies only apply to transit traffic and do not evaluate packets destined for the FortiGate itself. They are evaluated later in the sequence, after checks for device-bound traffic.

Local-in Policy is evaluated first for any traffic destined for FortiGate’s own interfaces or services. These include administrative access, routing protocols, VPN services, and other control-plane traffic. The firewall must evaluate this traffic before anything else to determine whether the access attempt is allowed. Because Local-in Policies protect the firewall itself, they precede all forwarding-based policy types and therefore are evaluated first. This makes Local-in Policy the correct answer.

DoS Policy examines traffic for signs of denial-of-service attacks. While important for security, DoS checks occur after determining whether the packet is aimed at the firewall or should be forwarded. DoS inspection typically takes place within the forwarding process, and therefore does not come before Local-in Policy evaluation. It focuses on flood detection, not initial policy classification.

Proxy Policy is used for proxy-based inspection modes such as explicit web proxy or SSL inspection. These policies apply only to traffic handled by the proxy engine and not to all firewall traffic. Proxy Policies are evaluated after higher-priority system checks such as Local-in Policies. Therefore, they are not the first evaluated.

Local-in Policy is thus the correct answer because it governs traffic directed at the firewall itself and must be evaluated before forwarding policies, DoS checks, or proxy logic. IPv4 Policies come later, DoS Policies protect against floods but do not precede Local-in decisions, and Proxy Policies apply only to proxy-enabled flows. Only Local-in Policies are evaluated first.

Question 36 

Which FortiGate feature allows traffic to bypass security processing for improved performance while still being counted and logged?

A) Policy Routing
B) NP Accelerated Path
C) Central NAT
D) Explicit Proxy

Answer: B)

Explanation 

Policy Routing directs traffic based on criteria such as source, destination, or application rather than relying strictly on routing tables. While powerful for controlling path selection, it does not provide a mechanism to bypass security inspection engines. Policy Routing influences the traffic’s path, not whether it bypasses CPU inspection.

NP Accelerated Path leverages hardware network processors to accelerate traffic by offloading sessions from the CPU. When traffic follows the accelerated path, it can bypass deep inspection while still being counted and logged. The session remains subject to basic checks but avoids CPU-intensive processing, greatly improving throughput. This mechanism is designed specifically for performance optimization and aligns with the requirement of bypassing security inspection while retaining visibility. Therefore, NP Accelerated Path is the correct answer.

Central NAT modifies NAT rules so they are centrally managed rather than embedded within policy rules. This improves NAT configuration efficiency but has no impact on bypassing CPU inspection or altering the security processing path. It is purely a management convenience and does not accelerate traffic or bypass security engines.

Explicit Proxy requires clients to use the proxy service for specific traffic types. This feature enables granular control and inspection of web and other protocols. Explicit Proxy increases processing load rather than bypassing inspection and therefore does not satisfy the performance requirement described in the question.

NP Accelerated Path is the correct answer because it enables sessions to bypass CPU inspection processing while still being logged and counted. Policy Routing determines path selection, Central NAT manages NAT rules, and Explicit Proxy increases inspection involvement. Only the NP Accelerated Path provides the bypass and performance optimization described.

Question 37 

Which feature in FortiGate helps identify and block malicious command-and-control communications using behavioral and intelligence-based analysis?

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

Answer: C)

Explanation 

Web Cache stores frequently accessed web content to improve performance and reduce bandwidth usage. Its function is purely related to optimization and does not include any threat detection or identification of command-and-control behavior. Because it does not inspect patterns of malicious communication or use intelligence feeds, it cannot block botnet activity.

Application Control identifies and regulates applications based on signatures and behavioral patterns. Although it can block risky applications, it does not specifically target malware command-and-control channels. Application Control can prevent unauthorized applications from operating but cannot reliably detect botnet communications designed to mimic legitimate traffic.

AntiBotnet is designed to detect and block communications between infected devices and malicious command-and-control servers. It uses threat intelligence, domain reputation, and behavioral detection to identify suspicious communication patterns. AntiBotnet can quarantine devices, stop outbound connections to known malicious addresses, and protect the network from lateral spread. Because it directly addresses command-and-control detection, it is the correct answer.

VLAN Tagging separates broadcast domains and creates network segmentation. Segmentation provides structure but does not include mechanisms for detecting malicious C2 traffic. VLANs alone cannot stop compromised hosts from reaching external malicious servers unless combined with other security controls. Therefore, VLAN Tagging is not designed for the threat-detection capability required.

AntiBotnet is the correct answer because it uses intelligence-driven analysis and behavior monitoring to identify and block command-and-control activity. Web Cache is for performance, Application Control focuses on application identification, and VLAN Tagging provides segmentation. Only AntiBotnet performs C2 behavior detection.

Question 38 

Which Fortinet product is designed to correlate security events across the enterprise and generate actionable incident alerts?

A) FortiAnalyzer
B) FortiClient
C) FortiAP
D) FortiSwitch

Answer: A)

Explanation 

FortiAnalyzer centralizes log collection and performs correlation, analytics, and reporting. It examines logs from firewalls, switches, wireless controllers, and endpoints to detect patterns indicative of threats. FortiAnalyzer uses built-in event handlers, rule-based alerts, and advanced analytics to generate incident notifications. Because it is explicitly designed to correlate events and produce actionable alerts, it is the correct answer.

FortiClient provides endpoint protection, vulnerability scanning, and secure remote access. While it detects local threats on endpoints, it does not correlate events across multiple network devices or generate enterprise-wide incident analysis. Its scope is limited to device-level protection rather than enterprise-level correlation.

FortiAP delivers wireless connectivity and integrates with FortiGate for security enforcement on the wireless edge. Although it provides telemetry regarding connected clients, it is not a central analytics engine and does not correlate events from different parts of the enterprise. Its focus is Wi-Fi access, not threat correlation.

FortiSwitch provides managed switching with NAC support and Security Fabric integration. Although it contributes logs and telemetry, it does not analyze or correlate them. FortiSwitch devices depend on FortiAnalyzer or FortiGate for deep analytics.

FortiAnalyzer is therefore the correct answer because its primary role is log correlation and generating alerts across enterprise devices. The other products provide important capabilities but do not perform correlation or cross-device incident analysis.

Question 39 

Which FortiGate feature prevents lateral movement by segmenting devices based on dynamic tags received from Security Fabric components?

A) Traffic Shaping
B) Fabric-based Segmentation
C) VLAN Pooling
D) Forward Error Correction

Answer: B)

Explanation 

Traffic Shaping regulates bandwidth and prioritizes traffic based on rules. Although it can enforce performance-oriented policies, it does not segment devices or limit lateral movement. Its purpose is throughput optimization, not security-based segmentation.

Fabric-based Segmentation allows FortiGate to dynamically isolate devices using tags from EMS, FortiNAC, or other fabric components. When a device is identified as risky, vulnerable, or untrusted, FortiGate can automatically restrict its movement across the network. This enables zero-trust segmentation and blocks lateral movement. Because it relies on dynamic posture information and tag-based enforcement, it is the correct answer.

VLAN Pooling distributes clients across multiple VLANs for scaling and wireless network balancing. While this can help manage large deployments, it does not enforce security segmentation based on device risk or fabric intelligence.

Forward Error Correction is a mechanism for improving signal quality across unreliable links. It has no relation to device segmentation or security enforcement and cannot prevent lateral movement.

Fabric-based Segmentation is correct because it uses dynamic tags to place devices into isolated security zones, preventing unauthorized movement. The other choices focus on performance, scaling, or link reliability rather than zero-trust segmentation.

Question 40 

Which FortiGate inspection mode buffers the entire file before scanning, allowing deeper analysis at the cost of increased latency?

A) Flow-based Inspection
B) Proxy-based Inspection
C) Web Filtering
D) IPS Offloading

Answer: B)

Explanation 

Flow-based Inspection scans traffic as it streams through the firewall. It analyzes packets incrementally without buffering the entire file. This method provides faster performance but less comprehensive analysis compared to proxy-based inspection. Because it does not perform full file buffering, it does not match the description of deeper but slower analysis.

Proxy-based Inspection buffers entire files or objects before scanning them, enabling deeper inspection capabilities such as thorough antivirus scanning and complete content inspection. This approach introduces higher latency but provides more accurate analysis, as the entire object is available for inspection. Because it matches the requirement of full buffering and deeper inspection, Proxy-based Inspection is the correct answer.

Web Filtering enforces category-based or URL reputation-based restrictions. While Web Filtering can operate via proxy mode, the feature itself is not the inspection mode. Web Filtering does not inherently buffer full files; it evaluates URLs and content categories rather than handling full file objects. It is therefore not the correct answer.

IPS Offloading uses hardware acceleration to inspect traffic for intrusion signatures. It scans packets efficiently but does not buffer entire files. IPS focuses on signature matching and anomaly detection at the packet or flow level rather than object-level buffering. Therefore, it does not satisfy the requirement of deeper analysis through full buffering.

Proxy-based Inspection is correct because it performs full object buffering and enables the most comprehensive analysis, at the cost of higher latency. Flow-based Inspection processes traffic inline without deep buffering, Web Filtering focuses on URLs, and IPS Offloading accelerates packet-level inspection. Only Proxy-based Inspection matches the described behavior.
