FCSS - Network Security 7.6 Support Engineer Questions 31–35 (page: 8)

Updated On: 10-Feb-2026

Which two statements about Security Fabric communications are true? (Choose two.)

  1. FortiTelemetry and Neighbor Discovery both operate using TCP.
  2. The default port for Neighbor Discovery can be modified.
  3. FortiTelemetry must be manually enabled on the FortiGate interface.
  4. By default, the downstream FortiGate establishes a connection with the upstream FortiGate using TCP port 8013.

Answer(s): C,D

Explanation:

FortiTelemetry is a critical part of Security Fabric communications and requires explicit configuration for each participating FortiGate interface. The administrative access setting "fabric" (corresponding to FortiTelemetry) must be manually enabled per interface on both upstream and downstream devices. This is performed in the GUI under Administrative Access or via the CLI using the command set allowaccess fabric for the relevant network interface. Without this step, FortiTelemetry communications will not occur on that interface.

Additionally, the default communication between downstream and upstream FortiGate units in the Security Fabric is over TCP port 8013. This port is well-documented as the standard for Security Fabric and FortiTelemetry connections, and must be open and permitted across the network path for connectivity and status enforcement between units. The downstream FortiGate initiates the connection to the upstream via this port unless otherwise configured. This has also been documented as a PCI-relevant port, showing its default usage.

Other options:

Neighbor Discovery in FortiOS uses IPv6 ND protocol, not TCP.

FortiTelemetry port (8013) can be modified, but the interface Administrative Access for the Security Fabric must be manually enabled; Neighbor Discovery port modification is not documented as a supported change for FortiGate.

Refer to the exhibit, which contains the output of diagnose vpn tunnel list.



Which command will capture ESP traffic for the VPN named DialUp_0?

  1. diagnose sniffer packet any 'ip proto 50'
  2. diagnose sniffer packet any 'host 10.0.10.10'
  3. diagnose sniffer packet any 'esp and host 10.200.3.2'
  4. diagnose sniffer packet any 'port 4500'

Answer(s): D



Exhibit.



Refer to the exhibit, which shows the output of diagnose automation test.

What can you observe from the output? (Choose two.)

  1. The automation stitch test is not being logged.
  2. The automation stitch test failed but the HA failover was successful.
  3. An HA failover occurred.
  4. The test was unsuccessful.

Answer(s): A,D



Refer to the exhibit, which shows partial outputs from two routing debug commands.



Which change must an administrator make on FortiGate to route web traffic from internal users to the internet, using ECMP?

  1. Set snat-route-change to enable.
  2. Set the priority of the static default route using port2 to 1.
  3. Set preserve-session-route to enable.
  4. Set the priority of the static default route using port1 to 10.

Answer(s): D



What are two reasons you might see iprope_in_check() check failed, drop when using the debug flow? (Choose two.)

  1. Packet was dropped because of policy route misconfiguration.
  2. Packet was dropped because of traffic shaping.
  3. Trusted host list misconfiguration.
  4. VIP or IP pool misconfiguration.

Answer(s): C,D
