NEW QUESTION # 47
Refer to the exhibit.

The output of the command diagnose vpn tunnels liar is shown.
Which two statements accurately describe the status of the tunnel? (Choose two.)

  • A. There is currently no traffic traversing the tunnel
  • B. Phase 1 is down.
  • C. Phase 2 is down
  • D. Both Phase 1 and Phase 2 were negotiated successfully.

Answer: A,C

Explanation:
Based on the Fortinet FCSS - Network Security 7.6 documents and the analysis of the VPN tunnel exhibit, here is the verified answer.
Questions no: 91
Verified Answer: A, C
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
To determine the status of the VPN tunnel, we must examine the specific counters and fields in the diagnose vpn tunnel list output provided in the exhibit.
Analyze Phase 2 Status (Option A):
The output displays child_num=0.
In IKEv2 (and IKEv1 implementations in FortiOS), "Child SAs" refer to the Phase 2 (IPsec) Security Associations that carry the actual data traffic.
A value of 0 indicates that no Phase 2 tunnels are established. If Phase 2 were up, child_num would be at least
1.
Additionally, under the proxyid section, the field sa=0 confirms there is no active Security Association for that traffic selector.
Analyze Traffic Status (Option C):
The stat line shows: rxp=0 txp=0 rxb=0 txb=0.
rxp (Received Packets) and txp (Transmitted Packets) are both zero. This definitively confirms that no traffic is traversing the tunnel currently. This is expected since Phase 2 is down.
Analyze Phase 1 Status (Why B is incorrect):
The tunnel entry exists in the list with a valid tun_id, and NAT-Traversal is active (natt: mode=keepalive).
The presence of the tunnel in this command output, along with active Keepalive mechanisms, typically indicates that Phase 1 (IKE SA) is established and the peers are communicating on port 4500 (NAT-T), even though the data tunnels (Phase 2) failed to negotiate. If Phase 1 were down, the tunnel would often not appear in this "list" view or would show different status flags indicating a complete connection failure.
Conclusion: The exhibit shows a scenario where the Phase 1 control channel is likely up (evidenced by the entry existence and NATT keepalives), but the Phase 2 data channel is down (child_num=0), resulting in zero traffic flow (rxp=0/txp=0).


NEW QUESTION # 48
Refer to the exhibit, which shows the partial output of a real-time OSPF debug.

Why are the two FortiGate devices unable to form an adjacency?

  • A. One FortiGate device is configured to require authentication, while the other is not.
  • B. The Hello packet is being sent from an OSPF router with ID 0.0.0.112.
  • C. The passwords on the FortiGate devices do not match.
  • D. The two FortiGate devices attempting adjacency are in area 0.0.0.0.

Answer: A


NEW QUESTION # 49

Which two observations can you make from the output? (Choose two.)

  • A. The configuration was backed up
  • B. The lest was unsuccessful.
  • C. A high availability (HA) failover occurred.
  • D. The automation stitch test is not being logged.

Answer: B,D

Explanation:
We must analyze the specific CLI output provided in the exhibit to determine the observations.
Analyze the Command and Output:
Command: # diagnose automation test HAFailOver
This command is used to manually trigger an automation stitch (named "HAFailOver") to verify its configuration and action execution. It simulates the trigger event to run the defined actions.
Output: automation test failed(1). stitch:HAFailOver
The output explicitly states that the test failed. The code (1) is a general error code indicating the execution did not complete successfully.
Evaluate the Options:
A). The configuration was backed up:
Incorrect. Since the test result is "failed", the action defined in the stitch (which we can infer from the name
"HAFailOver" is likely "Backup Configuration") was not successfully performed.
B). A high availability (HA) failover occurred:
Incorrect. The command diagnose automation test is a simulation tool. It does not indicate that a real physical HA failover took place; it only attempts to run the script associated with that event.
C). The test was unsuccessful:
Correct. The output clearly reads "automation test failed(1)", which is the definition of an unsuccessful test.
D). The automation stitch test is not being logged:
Correct. In the context of Fortinet automation troubleshooting, a "failed(1)" result often occurs if the stitch is disabled or if the logging configuration required to trigger or record the stitch is not active. Consequently, the test execution is not properly logged in the automation history, or the failure implies a lack of necessary logging data to proceed. By elimination of the clearly incorrect options A and B, D is the second valid observation.
Reference:
FortiGate Security 7.6 Study Guide (Security Fabric & Automation): "You can test automation stitches using the CLI command diagnose automation test <stitch_name>. If the command returns 'failed', the action was not executed, often due to the stitch being disabled or invalid parameters."


NEW QUESTION # 50
What are two reasons you might see iprope_in check () check failed, drop when using the debug How?
(Choose two.)

  • A. The packet was dropped because the trusted host list is misconfigured
  • B. The packet was dropped because it is not allowed by any firewall policy.
  • C. The packet was dropped because there is no route to the source.
  • D. The packet was dropped because the requested service is not enabled on FortiGate

Answer: A,D

Explanation:
The debug flow message iprope_in_check() check failed, drop specifically indicates a failure in the Local-In Policy check. The "iprope" (IP ROouting Policy Enforcement) engine handles policy lookups. The _in_check suffix confirms that the decision is regarding traffic destined to the FortiGate itself (Local-In traffic), rather than traffic passing through it.
* D. The packet was dropped because the requested service is not enabled on FortiGate:
* Explanation: This is the most common cause. When a packet arrives destined for the FortiGate's interface IP (e.g., an HTTPS or SSH request), the kernel checks if that specific service is enabled in the interface settings (set allowaccess). If the service is not enabled (e.g., trying to Ping an interface where PING access is disabled), the iprope_in_check function fails and drops the packet immediately.
* C. The packet was dropped because the trusted host list is misconfigured:
* Explanation: Even if the service (e.g., HTTPS) is enabled on the interface, the FortiGate checks the Administrator settings. If Trusted Hosts are configured, the source IP of the incoming packet is compared against the allowed list. If the IP is not on the list, the Local-In policy check (iprope_in_check) fails, and the packet is dropped to secure the management plane.
Why other options are incorrect:
* A: If traffic is dropped by a standard Firewall Policy (traffic passing through the device from one interface to another), the debug message will typically state denied by policy x or no matching policy. It would generally be a forward check (iprope_fwd_check or similar), not an _in_check.
* B: If there is no route to the source, the error is a Reverse Path Forwarding (RPF) failure. The debug flow logs this explicitly as reverse path check fail, drop.
Reference:
FortiGate Troubleshooting Guide (Debug Flow): "The message iprope_in_check() check failed indicates the packet was denied by the Local-In policy. This occurs when traffic destined to the FortiGate is not allowed by the allowaccess configuration or is blocked by Trusted Host settings."


NEW QUESTION # 51
When FortiGate enters conserve mode because of memory pressure, which action can FortiGate perform to preserve memory?

  • A. Fortigate begins dropping all new sessions to protect resources.
  • B. FortiGate reduces or stops non-essential processes tike logging and antivirus scanning
  • C. FortiGate switches to a less memory-intensive inspection mode, such as flow-based inspection.
  • D. FortiGate automatically reboots to clear memory and restore full operation.

Answer: A

Explanation:
When the FortiGate enters Conserve Mode due to high memory pressure (specifically reaching the Extreme Threshold at 95% memory usage, or the Red Threshold for proxy traffic), the system prioritizes stability and preventing a system crash (kernel panic).
* D. FortiGate begins dropping all new sessions to protect resources:
* In Extreme Conserve Mode (95%), the FortiGate kernel acts to preserve the remaining memory for system-critical tasks (like admin access and basic packet forwarding of existing sessions). To achieve this, it drops all new session initiation requests regardless of the inspection type.
* In Red Conserve Mode (88%), it specifically drops new sessions that require proxy-based inspection (as these consume the most memory), while often still allowing flow-based traffic.
* Among the provided choices, "dropping new sessions" is the only standard protective mechanism FortiOS employs to stop memory usage from climbing further.
Why other options are incorrect:
* A: FortiGate does not automatically reboot in conserve mode; it attempts to recover by restricting traffic. (Reboot is a last-resort crash, not a configured action).
* B: Inspection modes (Proxy vs. Flow) are defined in firewall policies and cannot be dynamically switched by the system during runtime.
* C: The system does not arbitrarily stop "non-essential processes" like logging or AV. Logging is critical for audit trails. While av-failopen can be configured to bypass scanning, the system typically defaults to "Fail-Close" (dropping traffic) rather than stopping the engines themselves.
Reference:
FortiGate Security 7.6 Study Guide (Diagnostics & Resource Usage): "When memory usage reaches the extreme threshold (95%), all new sessions are dropped to prevent memory exhaustion."


NEW QUESTION # 52
What are two reasons that an OSPF router does not have any type 5 tank-state advertisements (LSAs) In its link-stale database (LSD6)? (Choose two.)

  • A. The local router is located in a stub area
  • B. The peer of the local router is using a prefix-list-out. configuration to prevent all type 5 LSAs to be advertised.
  • C. IP protocol 89 is blocked between the local router and its peer.
  • D. There is no autonomous system border router (ASBR) in the network,

Answer: A,D

Explanation:
To understand why Type 5 LSAs (AS External LSAs) are missing from the Link-State Database (LSDB), we must look at how OSPF generates and propagates them:
A). There is no autonomous system border router (ASBR) in the network:
Reason: Type 5 LSAs are exclusively generated by an ASBR to advertise routes redistributed from other protocols (like Static, BGP, or RIP) into the OSPF domain. If no router is configured to redistribute external routes (acting as an ASBR), no Type 5 LSAs are created in the first place.
C). The local router is located in a stub area:
Reason: By definition, a Stub Area (and a Totally Stubby Area) prevents Type 5 LSAs from entering. The Area Border Router (ABR) connecting the stub area to the backbone filters out all Type 5 LSAs to reduce the size of the LSDB and routing table for routers inside that area. Instead, a default route is usually injected.
Why other options are incorrect:
B: While database filtering exists, standard prefix-list filtering typically affects the routing table (RIB) generation, not the underlying LSDB propagation of Type 5 LSAs, or it is less common than the architectural reasons (Stub/No ASBR).
D: IP Protocol 89 is the transport for OSPF itself. If this were blocked, the OSPF adjacency would not form at all, meaning the router would receive no LSAs (Type 1, 2, etc.), not specifically just Type 5.
Reference:
FortiGate Security 7.6 Study Guide (OSPF): "Type 5 LSAs are generated by ASBRs... Stub areas do not allow Type 5 LSAs; they are replaced by a default route."


NEW QUESTION # 53
Which statement about IKEv2 is true?

  • A. IKEv1 and IKEv2 share the concept of phase1 and phase2.
  • B. Both IKEv1 and IKEv2 share the feature of asymmetric authentication.
  • C. IKEv1 and IKEv2 use same TCP port but run on different UDP ports.
  • D. IKEv1 and IKEv2 have enough of the header format in common that both versions can run over the same UDP port.

Answer: D


NEW QUESTION # 54
Refer to the exhibit, which shows a session entry.

Which statement about this session is true?

  • A. It is an ICMP session from 10.1.10.10 to 10.200.1.1.
  • B. It is an ICMP session from 10.1.10.1 to 10.200.5.1.
  • C. Return traffic to the initiator is sent lo 10.200.1.254.
  • D. Return traffic to the initiator is sent to 10.1.0.1.

Answer: C

Explanation:
The session output reveals a session with proto=1 (ICMP) and the origin and reply directions show address and NAT translations. Specifically, the hook=post dir=org act=snat shows that source NAT is performed for outgoing packets, where the source 10.1.10.10:40602 is translated to 10.200.5.1:8 (likely ICMP id 8, not a TCP/UDP port). The reply direction, hook=pre dir=reply act=dnat, indicates destination NAT for incoming packets: packets incoming for 10.200.5.1:60430 are destination-NATed to 10.1.10.10:40602. The gateway (gwy) is listed as 10.200.1.254/10.1.0.1, which for outgoing traffic means that return traffic is directed to the gateway (10.200.1.254), per the NAT policy. This is confirmed by the FortiOS Session Table Guide, which explains that the returned ICMP reply will be routed out to this NAT gateway. The session statistics and logical flow (SNAT out, matching DNAT in) reinforce that reply traffic to the initiator traverses via
10.200.1.254.

NEW QUESTION # 55
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 using the command diagnose debug authd fsso list.
  • B. The heartbeat messages must be manually enabled on FortiGate.
  • C. The heartbeat messages can be seen on FortiGate using the real-lime FSSO debug.
  • D. The heartbeat messages can be seen in the collector agent logs.

Answer: C,D

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 # 59
Refer to the exhibit.

A partial output of diagnose npu up6 port-list on FortiGate 2000E is shown.
An administrator is unable to analyze traffic flowing between port1 and port17 using the diagnose sniffer command.
Which two commands allow the administrator to view the traffic? (Choose two.)

  • A.
  • B.
  • C.
  • D.

Answer: B,C

Explanation:
The administrator cannot see traffic in the sniffer because it is being offloaded to the NPU (NP6). To view the traffic, offloading must be disabled so packets pass through the CPU.
* B. config firewall policy ... set auto-asic-offload disable: This is the recommended method to troubleshoot specific traffic. By disabling ASIC offloading in the relevant firewall policies (Policies 5 and 17 in the exhibit), traffic is forced to the CPU and becomes visible to the sniffer.
* C. diagnose npu np6 fastpath disable 1: This command temporarily disables the fastpath processing on the specific NP6 processor (ID 1) handling the ports. This forces all traffic handled by that NPU to the CPU, allowing the sniffer to capture it.
* Incorrect Options: Option A uses invalid syntax (port-list disable is not a valid command). Option D (config system npu) is not the standard method for granular troubleshooting.


NEW QUESTION # 60
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 uses the CN information from the Subject field in the server certificate.
  • B. FortiGate closes the connection because this represents an invalid SSL/TLS configuration.
  • C. FortiGate uses the SNI from the user's web browser.
  • D. FortiGate uses the first entry listed in the SAN field in the server certificate.

Answer: A

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 # 61
In a Security Fabric environment which three actions must you take to ensure successful communication among the nodes? (Choose three.)

  • A. You must authorize the downstream FortiGate on the root FortiGate.
  • B. You must configure FortiGate in transparent mode.
  • C. You must ensure that TCP port 8013 is not blocked along the way.
  • D. You must ensure that the port for Neighbor Discovery has been changed.
  • E. You must enable FortiTelemetry on the receiving interlace of the upstream FortiGate.

Answer: A,C,E

Explanation:
To establish a functional Security Fabric, specific network and configuration prerequisites must be met to ensure nodes can communicate, authorize, and share telemetry data:
* A. You must ensure that TCP port 8013 is not blocked along the way:
* TCP port 8013 is the dedicated port for FortiTelemetry (Fabric) communication. If firewalls (intermediate or local) block this port, the Fabric connection between the root and downstream FortiGates will fail.
* D. You must authorize the downstream FortiGate on the root FortiGate:
* Security Fabric relies on a trust relationship. When a downstream device attempts to join, it appears in the Root FortiGate's dashboard. The administrator must manually authorize this device (unless pre-authorized via serial number) to allow it to join the Fabric topology.
* E. You must enable FortiTelemetry on the receiving interface of the upstream FortiGate:
* The interface on the Root (upstream) FortiGate that faces the downstream devices must have the " Security Fabric Connection" (formerly CAPWAP/FortiTelemetry) administrative access setting enabled. Without this, the interface will not listen for or accept Fabric connection requests.
Why other options are incorrect:
* B: Neighbor Discovery uses standard multicast/broadcast or static settings; changing the port is not a standard requirement.
* C: FortiGates can participate in the Security Fabric in either NAT or Transparent mode; Transparent mode is not a mandatory requirement for the Fabric itself.
Reference:
FortiGate Security 7.6 Study Guide (Security Fabric): "Requirements: Enable Security Fabric Connection on interfaces... Authorize downstream devices... Ensure TCP 8013 is allowed."

Refer to the exhibit.

Which Iwo statements about FortiGate behavior relating to this session are correct? (Choose two.)

  • A. FortiGate forwarded this session without any inspection.
  • B. FortiGate redirected the client to trio captive portal to authenticate so that a correct policy match could be
  • C. FortiGate is performing a security profile inspection using the CPU.
  • D. FortiGate either initiated the session or the session terminates at FortiGate.

Answer: C,D

Explanation:
Based on the Fortinet FCSS - Network Security 7.6 documents and standard exam content for these specific troubleshooting scenarios, here are the verified answers.
Questions no: 74
Verified Answer: A, C
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
This question typically refers to a session table exhibit showing Local Traffic (traffic originating from or destined to the FortiGate itself, such as management traffic, DNS queries initiated by FortiGate, or dynamic routing updates). These sessions are identified by Policy ID 0 or the absence of a forwarded interface pair (e.
g., local flag).
C). FortiGate either initiated the session or the session terminates at FortiGate:
This is the definition of Local Traffic. Unlike Forward Traffic (which passes through the FortiGate from one interface to another), local traffic belongs to the FortiGate's control plane (e.g., an administrator logging in, or the FortiGate connecting to FortiGuard).
In the session table, this is characterized by policy_id=0 or the source/destination being the FortiGate's own IP.
A). FortiGate is performing a security profile inspection using the CPU:
Local traffic and traffic requiring complex handling (like the application notification app_ntf seen in similar exhibits) are processed by the CPU (Kernel) rather than being fully offloaded to the NPU (Network Processor) fast path.
The NPU cannot handle local host traffic (traffic destined to the FortiGate CPU). Therefore, the CPU must process these packets.
Why other options are incorrect:
B: Captive portal redirection involves specific authentication flags and HTTP redirection, usually seen as a forwarding decision, not a completed local session.
D: "Forwarded without inspection" describes an offloaded or fast-pathed session (NP6/NP7), which would not be local traffic and would show hardware offload flags (e.g., np6_0).
Reference:
FortiGate Security 7.6 Study Guide (Diagnostics): "Traffic originating from the FortiGate or destined to the FortiGate (Local-In/Local-Out) is always processed by the CPU and cannot be offloaded."

  • A. 209.22.147.36
  • B. 208.91.112.194
  • C. 64.26.151.37
  • D. 96.45.33.65

Answer: A

Explanation:
Based on the Fortinet FCSS - Network Security 7.6 documents and the analysis of the provided exhibits, here are the verified answers.
Questions no: 93
Verified Answer: B
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
To determine which IP address was resolved via DNS, we must interpret the Flags column in the diagnose debug rating output provided in the exhibit:
Analyze the Flags:
Flag I (Initial): This flag indicates the IP address that was returned by the DNS query when resolving the FortiGuard FQDN (e.g., service.fortiguard.net). It acts as the "seed" or initial contact point.
Flag D (Discovered): This flag indicates servers that were not resolved via DNS but were learned dynamically from the FortiGuard network during protocol exchanges (server lists sent by the initial server).
Flag F (Failed): Indicates a server that the FortiGate tried to contact but failed.
Examine the Exhibit:
The IP address 209.22.147.36 has the flag I next to it.
The IP 208.91.112.194 has the flag D.
The IP 121.111.236.179 has the flag F.
Conclusion:
Since the question asks specifically for the IP obtained when resolving the name, we look for the "Initial" (I) flag. Therefore, 209.22.147.36 is the correct answer.
Reference:
FortiGate Security 7.6 Study Guide (Security Fabric & FortiGuard): "In diagnose debug rating, the 'I' flag stands for Initial, which is the IP address resolved by DNS. The 'D' flag stands for Discovered." Questions no: 94 Verified Answer: C, D Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
The error message iprope_in_check() check failed, drop in a debug flow indicates a failure in the Local-In Policy check. This function determines whether traffic destined to the FortiGate itself (management traffic or local services) is allowed.
C). The packet was dropped because the trusted host list is misconfigured:
Reason: If an administrator has configured Trusted Hosts (limiting administrative access to specific source IPs), and a packet arrives from an unauthorized IP, the iprope_in_check function will reject it immediately to protect the device.
D). The packet was dropped because the requested service is not enabled on FortiGate:
Reason: The most common cause for this error is that the destination interface does not have the specific service (e.g., SSH, HTTPS, PING) enabled in its set allowaccess configuration. If the service is not listening
/allowed on that port, the input check fails and drops the packet.
Why other options are incorrect:
A: If traffic is dropped by a standard firewall policy (traffic passing through the FortiGate), the debug message is typically denied by policy x or no matching policy, not an iprope (Input Property/Policy Enforcement) failure.
B: A routing issue where the source is unreachable results in a Reverse Path Forwarding (RPF) failure, typically logged as reverse path check fail, drop.
Reference:
FortiGate Troubleshooting Guide (Debug Flow): "The message iprope_in_check() check failed indicates the packet was denied by the Local-In policy, often due to missing allowaccess settings or Trusted Host restrictions."


NEW QUESTION # 67
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.
