Fortinet NSE 7 - Secure Networking 7.6 Architect Questions 66–70 (page: 15)

Updated On: 30-Sep-2026

Refer to the exhibit, which shows the output of diagnose sys session list.

If the HA ID for the primary device is 0, what happens if the primary fails and the secondary becomes the primary?

  1. The secondary device has this session synchronized; however, because application control is applied, the session is marked dirty and has to be re-evaluated after failover.
  2. Traffic for this session continues to be permitted on the new primary device after failover, without requiring the client to restart the session with the server.
  3. The session will be removed from the session table of the secondary device because of the presence of allowed error packets, which will force the client to restart the session with the server.
  4. The session state is preserved but the kernel will need to re-evaluate the session because NAT was applied.

Answer(s): B

Explanation:

The decisive session-state flag is synced. Fortinet defines this flag as indicating that the session has been synchronized to the other HA members. The session was created on HA member 0, and a synchronized copy is available to the secondary device.
The FortiOS 7.6 Administrator Study Guide states: ''When you enable session synchronization, the new primary can resume communication for sessions after a failover event.'' It further explains that session pickup allows existing sessions to continue through the newly elected primary with minimal or no interruption. Therefore, the established TCP session remains usable, and the client does not need to establish a new connection.
The may_dirty flag does not mean that the session is currently dirty. It identifies an allowed session that can be marked dirty later if a firewall-policy, routing, or related configuration change requires re-evaluation. The output does not contain the separate dirty flag. Additionally, app_ntf represents block-notification handling; it does not prove that application control is inspecting the session. The fields app_list=0 and app=0 reinforce this.
The allow_err values are session statistics and do not cause session deletion. Although act=snat and act=dnat confirm NAT, the translation tuples are part of the synchronized session state and do not independently require re-evaluation after FGCP failover.



MULTIPLE CHOICE
What are two functions of automation stitches? (Choose two.)

  1. You can configure automation stitches on any FortiGate device in a Security Fabric environment.
  2. You can configure automation stitches to execute actions sequentially by taking parameters from previous actions as input for the current action.
  3. You can set an automation stitch configured to execute actions in parallel to insert a specific delay between actions.
  4. You can create automation stitches to run diagnostic commands and attach the results to an email message when CPU or memory usage exceeds specified thresholds.

Answer(s): B,D

Explanation:

Without specific answer options, the two functions of automation stitches cannot be confirmed. Automation stitches in FortiGate are used to: orchestrate responses to triggered events, automate complex workflows, execute multiple actions based on conditions, integrate with external systems, enable automated threat response, and automate administrative tasks. Two specific functions would depend on the provided options.



Refer to the exhibit, which a network topology and a partial routing table.

FortiGate has already been configured with a firewall policy that allows all ICMP traffic to flow from port1 to port3.
Which changes must the administrator perform to ensure the server at 10.4.0.1/24 receives the echo reply from the laptop at 10.1.0.1/24?

  1. Enable asymmetric routing under config system settings.
  2. Change the configuration from strict RPF check mode to feasible RPF check mode.
  3. A firewall policy that allows all ICMP traffic from port3 to port1.
  4. Modify the default gateway on the laptop from 10.1.0.2 to 10.2.0.2.

Answer(s): A

Explanation:

The exhibit showing the network topology and routing table is not visible. To ensure echo replies flow correctly from 10.4.0.1/24 back to 10.1.0.1/24, the administrator may need to: add a return route/policy to allow reply traffic, configure a firewall policy allowing ICMP replies in the opposite direction, adjust routing to ensure proper path for return traffic, or configure source NAT/policy NAT settings appropriately. Specific changes depend on the exhibit details.



Refer to the exhibit, which shows the partial output of FortiOS kernel slabs.

Which statement is true?

  1. The total slab size of the sctp_session slab is 0 kB and is associated with the user space.
  2. The total slab size of the ip_session slab is 3600 kB and is associated with the user space.
  3. The total slab size of the ip6_session slab is 1300 kB and is associated with the kernel.
  4. The total slab size of the tcp_session slab is 7500 kB and is associated with the kernel.

Answer(s): D

Explanation:

The study guide states:
''The kernel memory slabs are collections of objects with a common purpose. The kernel uses them to store information in memory.''
It also gives the exact calculation rule:
''Total slab size = available objects x object size''
From the exhibit:
tcp_session 3 5 1500 ...
So:
available objects = 5
object size = 1500
Therefore:
Total slab size = 5 1500 = 7500 kB
That makes D correct, and it is associated with the kernel, not user space.
Why the other options are wrong:
A is wrong because sctp_session 0 0 1600 ... gives 0 1600 = 0, but slabs are associated with the kernel, not user space.
B is wrong because ip_session 1 3 1200 ... gives 3 1200 = 3600, but again slabs are kernel memory, not user space.
C is wrong because ip6_session 0 0 1300 ... gives 0 1300 = 0, not 1300.



MULTIPLE CHOICE
Refer to the exhibit, which shows one way communication of the downstream FortiGate with the upstream FortiGate within a Security Fabric.

What three actions must you take to ensure successful communication? (Choose three.)

  1. You must authorize the downstream FortiGate on the root FortiGate.
  2. FortiGate must not be in NAT mode.
  3. Ensure TCP port 8013 is not blocked along the way.
  4. You must enable Security Fabric/Fortitelemetry on the receiving interface of the upstream FortiGate.
  5. Ensure the port for Neighbor Discovery has been changed.

Answer(s): A,C,D
