NEW QUESTION # 12
Consider the scenario where the server name indication (SNI) does not match either the common name (CN) or any of the subject alternative names (SAN) in the server certificate.
Which action will FortiGate take when using the default settings for SSL certificate inspection?
- A. FortiGate closes the connection because this represents an invalid SSL/TLS configuration.
- B. FortiGate uses the SNI from the user's web browser.
- C. FortiGate uses the CN information from the Subject field in the server certificate.
- D. FortiGate uses the first entry listed in the SAN field in the server certificate.
Answer: C
Explanation:
When FortiGate performs SSL certificate inspection with default settings, it checks if the Server Name Indication (SNI) matches either the Common Name (CN) or any Subject Alternative Name (SAN) in the server certificate. If there is no match, FortiGate does not block the connection; instead, it uses the CN value from the certificate's subject field to continue web filtering and categorization.
This behavior is described in the official Fortinet 7.6.4 Administration Guide:
"Check the SNI in the hello message with the CN or SAN field in the returned server certificate: Enable: If it is mismatched, use the CN in the server certificate." This is the default (Enable) mode, which differs from the Strict mode that would block the mismatched connection.
By default, this policy ensures service continuity and prevents disruptions due to certificate mismatches, allowing FortiGate to log and inspect based on the CN even when the requested SNI does not match. It provides a balance between connection reliability and the accuracy of filtering by certificate identity, allowing security policies to remain functional without unnecessary blocks. This approach is recommended by Fortinet to maintain usability for end-users while still supporting granular inspection.

NEW QUESTION # 15
Refer to the exhibit, which shows the output of a policy route table entry.
Which type of policy route does the output show?
- A. An SD-WAN rule
- B. A regular policy route
- C. An ISDB route
- D. A regular policy route, which is associated with an active static route in the FIB
Answer: C
Explanation:
The exhibit for question 4 shows a policy route table entry, and key fields are as follows:
* internet service(1) : Fortinet-FortiGuard(1245324,0.0.0.0,0.0.0.0)
According to the Fortinet official documentation, when a policy route is based on Internet Service Database (ISDB) entries, the route entry will specifically mention "internet service," showing the service being referenced (in this example, Fortinet-FortiGuard). This is fundamentally different from a regular policy route, which is defined by source, destination, and service wildcards without referencing an ISDB signature. A regular policy route's output would not contain the line "internet service." Policy routes that use ISDB allow FortiGate to steer traffic for specific well-known services (like FortiGuard, Google, Microsoft) based on traffic pattern recognition, even if the destination IP is dynamic. The matching and route selection follow the ISDB tag and can coexist with static or regular policy routes.
Thus, this entry is correctly and uniquely an ISDB route, as explained in the FortiOS policy routing documentation and ISDB configuration references.

NEW QUESTION # 16
Refer to the exhibits,
which show the configuration on FortiGate and partial session information for internet traffic from a user on the internal network. If the priority on route ID 2 were changed from 10 to 0, what would happen to traffic matching that user session? (Choose one answer)
- A. The session would remain in the session table, and its traffic would egress from port2.
- B. The session would remain in the session table, and its traffic would egress from port1.
- C. The session would be deleted, and the client would need to start a new session.
- D. The session would remain in the session table, but its traffic would now egress from both port1 and port2.
Answer: C
Explanation:
The correct answer is A. This behavior is dictated by the configuration command set snat-route-change enable shown in Exhibit 1 under config system global.
* Routing Change: By changing the priority of route ID 2 from 10 to 0, it becomes lower than route ID 1 (priority 5). In FortiOS, a lower priority value indicates a more preferred route. Consequently, the active route for the destination changes from port1 to port2.
* SNAT Implication: The existing session (shown in Exhibit 2) is using Source NAT (SNAT) with the IP address associated with port1 (10.200.1.1). If the traffic were simply switched to port2, the source IP would be incorrect for that interface and the return traffic would likely fail or be dropped.
* snat-route-change enable: This specific setting instructs the FortiGate on how to handle established SNAT sessions when a routing change occurs that alters the preferred outgoing interface. When enabled, if a route change forces an SNAT session to a new interface, FortiGate flushes (deletes) the session from the session table. This is necessary because a live TCP session cannot survive a change in its source IP address. The client must initiate a new session, which will then be created using the new correct route (port2) and the corresponding new SNAT IP.
If this setting were disabled, the session would likely remain "sticky" to the original interface (port1) until it closed, provided the route still existed. However, the explicit configuration forces the deletion.

NEW QUESTION # 21 
The output of a policy route table entry is shown.
Which type of policy route does the output show?
- A. An ISDB route
- B. An SD-WAN rule
- C. A regular policy route, which is not associated with an active static route in the FIB
- D. A regular policy route, which is associated with an active static route in the FIB
Answer: B
Explanation:
To determine the type of policy route, we must interpret the specific flags and fields visible in the diagnose firewall proute list (or similar kernel table) output provided in the exhibit Identify Key Indicators:
The most critical field in the output is vwl_service=1(test123).
It also lists vwl_mbr_seq=1 5.
Decode the Terminology:
vwl: This stands for Virtual WAN Link. In FortiOS, "Virtual WAN Link" is the legacy internal name for the SD-WAN feature. Even in newer firmware versions (7.x), the kernel and CLI debugs often still refer to SD- WAN objects as vwl.
vwl_service: This specifically refers to an SD-WAN Rule (also known as an SD-WAN Service). The name (test123) is the name given to that specific SD-WAN rule by the administrator.
Evaluate the Options:
A & D (Regular Policy Route): Standard policy routes (configured under config router policy) do not carry the vwl_service tag. They are typically identified by simple gateway or interface instructions without the SD- WAN service abstraction.
B (ISDB Route): While SD-WAN rules can use the Internet Service Database (ISDB) as a destination, the structure of the route entry shown here-specifically defined by a vwl_service ID-classifies it fundamentally as an SD-WAN rule, regardless of the destination object.
C (An SD-WAN rule): The presence of vwl_service and vwl_mbr_seq (SD-WAN member sequence) definitively identifies this entry as a rule generated by the SD-WAN subsystem.
Conclusion: The output shows a route controlled by the SD-WAN engine (vwl), confirming it is an SD-WAN rule.
Reference:
FortiGate Security 7.6 Study Guide (SD-WAN): "In the kernel routing table and debugs, SD-WAN rules are often referenced as vwl (Virtual WAN Link) services. The vwl_service field indicates the specific SD-WAN rule ID and name."
NEW QUESTION # 22
Refer to the exhibits.
FGT-1 is an area border router (ABR) that has interfaces in OSPF areas 0.0.0.0 and 0.0.0.5. FGT-3 acts as an autonomous system border router (ASBR), importing static routes into OSPF. FGT-2 is an internal router with all its interfaces belonging to area 0.0.0.5. FGT-1 is receiving all advertised routes from FGT-2, however, FGT-3 is not receiving any of the advertised routes from FGT-1. What is the most likely reason for this?
(Choose one answer)
- A. FGT-3 and FGT-2 have not formed an OSPF adjacency yet.
- B. Area 0.0.0.5 is configured not to propagate type 5 LSAs.
- C. FGT-2 is configured with a distribution list to block all advertised routes from FGT-3.
- D. IP protocol 89 is blocked between FGT-1 and FGT-3.
Answer: B
Explanation:
The get router info ospf database brief output on FGT-2 clearly indicates that Area 0.0.0.5 is configured as a
[Stub] area.
In OSPF, a Stub Area is specifically designed to reduce the size of the Link State Database (LSDB) on internal routers. The primary behavior of a Stub area is that it does not accept Type 5 (AS External) LSAs.
* FGT-3 is the ASBR (Autonomous System Border Router) and is importing static routes, which are generated as Type 5 LSAs in the OSPF domain.
* FGT-1 acts as the ABR (Area Border Router). Because Area 0.0.0.5 is a Stub area, FGT-1 blocks these Type 5 LSAs from entering Area 0.0.0.5.
* Consequently, FGT-2 will not receive the specific external routes advertised by FGT-3. Instead, the ABR (FGT-1) injects a default route (0.0.0.0/0) into the Stub area to allow connectivity to the external world, which is visible in the database output.
While the question text mentions FGT-3 not receiving routes, the definitive configuration shown in the exhibit is the Stub area setting, which directly corresponds to the blocking of Type 5 LSA propagation (Option A).
NEW QUESTION # 23
Which two statements are true regarding heartbeat messages sent from an FSSO collector agent to FortiGate?
(Choose two.)
- A. The heartbeat messages can be seen on FortiGate using the real-lime FSSO debug.
- B. The heartbeat messages can be seen in the collector agent logs.
- C. The heartbeat messages must be manually enabled on FortiGate.
- D. The heartbeat messages can be seen using the command diagnose debug authd fsso list.
Answer: A,B
Explanation:
According to the official Fortinet documentation (Technical Tip: Useful FSSO Commands), heartbeat messages play a crucial role in communication between the FSSO Collector Agent and FortiGate. These messages are regularly sent from the Collector Agent to verify its status, maintain session awareness, and confirm connectivity between the authentication infrastructure and FortiGate appliances.
Option B is confirmed by Fortinet, as the collector agent logs on Windows or its management console will specifically note heartbeat events, connection status, and any issues maintaining contact with FortiGate units.
Option C is validated by both official CLI documentation and the technical tip linked. On FortiGate, heartbeat messages from the collector agent are visible using real-time debug tools such as diagnose debug application authd or FSSO-specific commands. These enable administrators to monitor live logon states, session status, and connection health directly from the FortiGate CLI. The debug stream shows heartbeats received and their effect on active logons, associating health monitoring with active sessions.
Heartbeat operation is fully automated once FSSO is set up-there is no requirement for manual enablement or configuration, aligning with Fortinet's philosophy of seamless integration and centralized management across the Security Fabric. This ensures that both FortiGate and the collector agent can quickly and reliably detect any miscommunication or outage, addressing authentication issues proactively.

NEW QUESTION # 24
Refer to the exhibit.
The modified output of live routing kemel is shown
Which two statements about the output are (rue? (Choose two.)
- A. The default static route through 10.200.1 254 is in the forwarding information* base.
- B. FortiGate is performing ECMP using both default static routes.
- C. The local FortiGate is receiving only one LSA from one OSPF neighbor.
- D. The BGP route to 10.0.4.0/24 is not in the forwarding information base.
Answer: A,D
Explanation:
We must analyze the flags (*, >, S, O, B) and Administrative Distances (AD) shown in the get router info routing-table database exhibit to determine the correct statements.
Analysis for Option A (The BGP route to 10.0.4.0/24 is not in the forwarding information base):
True. Look at the entry for 10.0.4.0/24.
There is an OSPF route: O *> 10.0.4.0/24 [110/2]. The * indicates it is in the FIB, and > indicates it is the selected route.
There is a BGP route: B 10.0.4.0/24 [200/10]. This line lacks the * flag.
Reason: The OSPF route has an Administrative Distance of 110. The BGP route (iBGP) has an AD of 200.
Since 110 is lower than 200, OSPF wins, and the BGP route is not installed in the Forwarding Information Base (FIB).
Analysis for Option B (The default static route through 10.200.1.254 is in the forwarding information base):
True. Look at the 0.0.0.0/0 entries.
The first entry is S *> 0.0.0.0/0 [10/0] via 10.200.1.254.
The * flag confirms this specific route is installed in the FIB.
The second static route (via 10.200.2.254) has a higher distance ([20/0]) and no * flag, so it is inactive.
Why C is False: ECMP (Equal Cost Multi-Path) requires routes to have the same cost/priority. Here, one static route has AD 10 and the other has AD 20. They are not equal, so ECMP is not performed.
Why D is False: The routing table database shows active routes, not the raw Link State Advertisement (LSA) database. You cannot determine the number of LSAs received solely from this output.
Reference:
FortiGate Security 7.6 Study Guide (Routing): "The routing table database displays all known routes... The * indicates the route is in the FIB... Lower Administrative Distance is preferred."
NEW QUESTION # 25
Refer to the exhibit, which shows the output of a policy route table entry.
Which type of policy route does the output show?
- A. An SD-WAN rule
- B. A regular policy route
- C. An ISDB route
- D. A regular policy route, which is associated with an active static route in the FIB
Answer: C
Explanation:
The exhibit for question 4 shows a policy route table entry, and key fields are as follows:
internet service(1) : Fortinet-FortiGuard(1245324,0.0.0.0,0.0.0.0)
According to the Fortinet official documentation, when a policy route is based on Internet Service Database (ISDB) entries, the route entry will specifically mention "internet service," showing the service being referenced (in this example, Fortinet-FortiGuard).

NEW QUESTION # 27
Exhibit.
Refer to the exhibit, which shows the output of a diagnose command.
What can you conclude about the debug output in this scenario?
- A. There is a natural correlation between the value in the FortiGuard-requests field and the value in the Weight field.
- B. The first server provided to FortiGate when it performed a DNS query looking for a list of rating servers, was 121.111.236.179.
- C. Servers with a negative TZ value are less preferred for rating requests.
- D. FortiGate used 64.26.151.37 as the initial server to validate its contract.
Answer: D
Explanation:
The exhibit displays the output from the diagnose debug rating command on a FortiGate device. This command is used to display information about FortiGuard Web Filtering or other security-related queries performed by FortiGate to FortiGuard servers. Official Fortinet documentation outlines the meaning of each field in the server list. The FortiGate maintains a list of available FortiGuard servers, selecting the optimal server based on factors such as weight, round-trip time (RTT), and regional settings.
The very first entry in the server list after "Server List" is the server FortiGate initially uses, prioritized by factors such as proximity and RTT. Here, 64.26.151.37 is listed first, and the FortiGuard-requests value confirms that this server handled the highest number of requests.
The IPs, weights, and lost/failed counters are monitored for server performance and selection over time.
FortiGate's default operational logic is to try the first entry for contract validation and use the next in the list if the first is unavailable or has high latency or packet loss.
There is no direct correlation between the Weight and the number of FortiGuard-requests. The servers with higher or lower weights may still handle different request volumes based on availability and performance.
The TZ (time zone) value's sign (positive or negative) does not affect server preference; it is informational, showing the server's location relative to UTC, not a rating metric.
DNS query results for FortiGuard servers are not shown here, and the provided servers are not returned in DNS query order.
This command and interpretation are detailed in the FortiOS Administration Guide's section describing FortiGuard server selection and contract validation processes.

NEW QUESTION # 30
Which three common FortiGate-to-collector-agent connectivity issues can you identify using the FSSO real- time debug? (Choose three.)
- A. FortiGate cannot reach the IP address of the collector agent.
- B. The pro-shared key does not match
- C. The SSL certificate used for FSSO over SSL has expired.
- D. The connection was refused. There may be a mismatch of the TCP port.
- E. The group filters do not match.
Answer: A,B,D
Explanation:
The diagnose debug authd fsso server command is the primary tool for troubleshooting communication between the FortiGate and the FSSO Collector Agent. This debug output reveals the status of the connection and the reasons for failure. The three most common connectivity issues identified by this debug are:
* FortiGate cannot reach the IP address of the collector agent (Option C): The debug will show connection timeouts or "host unreachable" errors if the Layer 3 connectivity is missing.
* The connection was refused / Port mismatch (Option B): If the FortiGate can reach the IP but the Collector Agent is not listening on the specified port (default 8000), the debug will display "Connection refused." This often happens if the port configured on the FortiGate does not match the listening port on the agent.
* The pre-shared key does not match (Option D): If the IP and Port are correct, the next step is authentication. If the password configured on the FortiGate does not match the one on the Collector Agent, the debug will explicitly show an "Authentication failed" or "password mismatch" error during the handshake.
Note on other options: Option A (SSL) is less common than basic connectivity/auth mismatches. Option E (Group filters) relates to user processing logic, which occurs after connectivity is established.

An administrator Is expecting to receive advertised route 8.8.8.8/32 from FGT-A. On FGT-B, they confirm that the route is being advertised and received, however, the route is not being injected into the routing table.
What is the most likely cause of this issue?
- A. A batter route to the 8.8.8.8/32 network exists in the routing table.
- B. The administrator has misconfigured redistribution of routes on FGT-A.
- C. FGT-B is configured with a distribution list denying the 8.8.8.8/32 network to be injected into the routing table.
- D. FGT-B is configured with a prefix list denying the 8.8.8.8/32 network to be injected into the routing table.
Answer: D
Explanation:
The 8.8.8.8/32 route is visible in the OSPF database on FGT-B but not installed into the routing table-the most likely explanation is that FGT-B is filtering it from being installed.
