Fortinet FCSS - Network Security 7.6 Support Engineer Sample Questions (Q75-Q80):

NEW QUESTION # 75
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.)

Answer: B,D

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 # 76
Refer to the exhibit.

The administrator did not override the FortiGuard FODN or IP address in the FortiGate configuration Which IP address did FortiGate get when resolving the servicem,fortiguard.net name?

Answer: C

Explanation:
The study guide explicitly explains the FortiGuard flags shown by diagnose debug rating:
* D = Default
* "IP addresses of servers received from DNS resolution"
It then clarifies even more specifically:
* "D = The IP address FortiGate got when resolving the service.fortiguard.net name (usually two or three servers have this flag, if the administrator didn ' t overwrite the FortiGuard FQDN or IP address in the FortiGate configuration)" In the exhibit, among the answer choices, the IP address marked with the D flag is 208.91.112.194 .
Therefore, that is the IP FortiGate got from resolving service.fortiguard.net.
Why the other options are wrong:
* B. 209.22.147.36 is not the correct choice because in the exhibit it is not the DNS-resolution entry identified by the D flag
* C. 64.26.151.37 has no D flag
* D. 96.45.33.65 has no D flag
So the verified answer is: A .


NEW QUESTION # 77
Which two statements are true regarding heartbeat messages sent from an FSSO collector agent to FortiGate?
(Choose two.)

Answer: B,C

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 # 78
Exhibit.

Refer to the exhibit, which shows the output of diagnose automation test.
What can you observe from the output? (Choose two.)

Answer: B,C


NEW QUESTION # 79
When FortiGate enters conserve mode because of memory pressure, which action can FortiGate perform to preserve memory?

Answer: C

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."
