Refer to the exhibit, which shows a session table entry.



Which statement about FortiGate behavior relating to this session is true?

  1. FortiGate forwarded this session without any inspection.
  2. FortiGate is performing a security profile inspection using the CPU.
  3. FortiGate redirected the client to the captive portal to authenticate, so that a correct policy match could be made.
  4. FortiGate applied only IPS inspection to this session.

Answer(s): B

Explanation:

The session table entry provided shows detailed information about a specific network session passing through the FortiGate device. From the session details, we can see that the session has various attributes such as state, protocol, policy, and inspection details.

The session state (proto_state=11) indicates that the session is being actively processed and inspected.

The npd_state=00000000 suggests that the session is being handled by the CPU rather than offloaded to a Network Processor (NP).

The session is marked for security profile inspection, evident from the detailed byte/packet counts and other session parameters.

From these indicators, it's clear that FortiGate is using its CPU to perform security profile inspection on this session rather than simply forwarding the traffic without inspection or relying solely on IPS inspection.

What is the diagnose test application ipsmonitor 5 command used for?

  1. To disable the IPS engine
  2. To provide information regarding IPS sessions
  3. To restart all IPS engines and monitors
  4. To enable IPS bypass mode

Answer(s): C

Explanation:

The command diagnose test application ipsmonitor 5 is used to restart all IPS (Intrusion Prevention System) engines and monitors on the FortiGate device. This command is part of the diagnostic tools available for troubleshooting and maintaining the IPS functionality on the FortiGate.

Running this command forces the IPS system to reset and reinitialize, which can be useful in situations where the IPS functionality appears to be malfunctioning or not responding correctly.

This action helps in clearing any issues that might have arisen due to internal errors or misconfigurations, ensuring that the IPS engines operate correctly after the restart.



Refer to the exhibit.



Refer to the exhibit, which shows the modified output of the routing kernel.

Which statement is true?

  1. The BGP route to 10.0.4.0/24 is not in the forwarding information base.
  2. The default static route through port2 is in the forwarding information base.
  3. The default static route through 10.200.1.254 is not in the forwarding information base.
  4. The egress interface associated with static route 8.8.8.8/32 is administratively up.

Answer(s): B

Explanation:

The routing table shown in the exhibit lists all the routes known to the FortiGate device. It includes routes learned through different protocols such as BGP, OSPF, and static routes.

The entry S * 0.0.0.0/0 [20/0] via 10.200.2.254, port2, [5/0] indicates that there is a static route to the default gateway (0.0.0.0/0) through port2 with a gateway IP of 10.200.2.254.

The asterisk * next to the route signifies that this route is selected and currently active in the forwarding information base (FIB). This means the FortiGate uses this route to forward packets destined for addresses not otherwise specified in the routing table.

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 _ were changed from 10 to 0, what would happen to traffic matching that user session?

  1. The session would be deleted, and the client would need to start a new session.
  2. The session would remain in the session table, but its traffic would now egress from both port1.

    andport2.
  3. The session would remain in the session table, and its traffic would egress from port2.
  4. The session would remain in the session table, and its traffic would egress from port1.

Answer(s): C

Explanation:

The exhibits show the configuration of static routes and a session table entry for an active session. The static routes are configured with different priorities:

Route through port1 with a gateway of 10.200.1.254 and priority 5.

Route through port2 with a gateway of 10.200.2.254 and priority 10.

If the priority of the route through port2 is changed from 10 to 0, this route will become more preferred than the route through port1 because lower priority values indicate higher preference. As a result, the traffic for the existing session will switch to using the more preferred route:

The session would remain active in the session table, as FortiGate does not immediately clear sessions upon route changes unless explicitly configured to do so.

The traffic for the session would then start egressing from port2, which now has the higher priority route due to its lower priority value.
