Fortinet FCSS - Network Security 7.6 Support Engineer Sample Questions (Q121-Q126):

NEW QUESTION # 121
In IKEv2, which exchange establishes the first CHILD_SA?

A. IKE_Auth
B. CREATE_CHILD_SA
C. IKE_SA_INIT
D. INFORMATIONAL

Answer: B

NEW QUESTION # 122
Exhibit.

Refer to the exhibit, which shows the output of get system ha status.
NGFW-1 and NGFW-2 have been up for a week.
Which two statements about the output are true? (Choose two.)

A. If a configuration change is made to the primary FortiGate at this time, the secondary will initiate a synchronization reset.
B. If port 7 becomes disconnected on the secondary, both FortiGate devices will elect itself as primary.
C. If no action is taken, the primary FortiGate will leave the cluster because of the current sync status.
D. If FGVM...649 is rebooted. FGVM...650 will become the primary and retain that role, even after FGVM...649 rejoins the cluster.

Answer: B,D

Explanation:
* FortiGate HA Troubleshooting and Synchronization Guides
* Fortinet Admin Guide: HA Primary Role Retention, Cluster Break-up Due to Out-of-Sync Status

NEW QUESTION # 123
Exhibit.

Refer to the exhibit, which contains a screenshot of some phase 1 settings.
The VPN is not up. To diagnose the issue, the administrator enters the following CLI commands on an SSH session on FortiGate:

However, the IKE real-time debug does not show any output. Why?

A. The log-filter setting is incorrect. The VPN traffic does not match this filter.
B. The debug shows only error messages. If there is no output, then the phase 1 and phase 2 configurations match.
C. The administrator must also run the command diagnose debug enable.
D. Replace diagnose debug application ike -1 with diagnose debug application ipsec -1.

Answer: C

Explanation:
To display debug output on FortiGate devices, you must always run both the application-specific debug command and the global debug enable command. The command diagnose debug application ike -1 sets up the detail level for the IKE daemon debug, but it does not display any debug output on its own. As described in the FortiOS CLI debugging manuals, the command diagnose debug enable activates debug output on the console, making all previously set debugs visible. This is especially important for VPN troubleshooting- without the enable command, no output appears even if there is VPN traffic.
The correct diagnostic sequence is:
diagnose debug application ike -1
diagnose debug enable
This procedure is found in every FortiOS CLI debug tutorial and troubleshooting workflow.

NEW QUESTION # 124
Refer to the exhibit, which shows a partial output of a real-time LDAP debug.

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

A. FortiOS is performing the second step (Search Request) in the LDAP authentication process.
B. FortiOS collects the user group information.
C. The user was found in the LDAP tree, whose root is TAC.ottawa.fortinet.com.
D. FortiOS performs a bind to the LDAP server using the user ' s credentials.

Answer: A,C

Explanation:
The exhibit includes these key debug lines:
* start_search_dn-base: ' DC=TAC,DC=ottawa,DC=fortinet,DC=com ' filter:sAMAccountName=jsmith
* get_all_dn-Found DN 1:CN=John Smith,CN=Users,DC=TAC,DC=ottawa,DC=fortinet,DC=com The study guide explains that in regular bind , LDAP authentication has four steps , and that during step 2 , FortiGate searches the LDAP tree to find the user's DN:
"During the second step, FortiGate does a search query in the LDAP database to find the user's location-in other words, the user's DN. If the user is found, the server replies with the user's DN." It also states for the real-time debug of step 2:
"An fnbamd_ldap_build_dn_search_req-base message indicates that FortiGate is performing step two:
searching for the user in the LDAP tree. This message includes the base branch (distinguished name setting) and the name of the attribute used to locate the user... If the LDAP server finds the user, the output shows the user's full DN." That directly proves:
* D is correct because the debug is showing step 2: Search Request
* A is correct because the base DN and found DN are under DC=TAC,DC=ottawa,DC=fortinet, DC=com, which corresponds to the LDAP domain/tree root TAC.ottawa.fortinet.com Why the other options are wrong:
* B is wrong because binding with the user's credentials is step 3 , not the step shown here. The study guide says: "Step 3 - Bind user credentials" and shows that this happens later with fnbamd_ldap_build_userbind_req / __ldap_build_bind_req-Binding to ' CN=John Smith... '
* C is wrong because collecting user group information is step 4 , not the step shown in the exhibit.
The study guide says: "The last step is to get the user group information" and shows step 4 with Attr query / memberOf search

NEW QUESTION # 125
Refer to the exhibit.

The output of diagnose sys session list command is shown.
If the HA ID for the primary device is 9, what happens if the primary fails and the secondary becomes the primary?

A. The session state is preserved but the kernel will re-evaluate the session because the routing information will be flushed
B. The session is synchronized with the secondary device, however, because application control is applied. the session is marked dirty and has to be reevaluated after failover.
C. The session continues to permit traffic on the new primary device after failover. without requiring the client to restart the session with the server.
D. The session will be removed from the session table of the secondary device because the TCP session is not yet fully established.

Answer: C

Explanation:
The output of the diagnose sys session list command provides the critical evidence needed to determine the behavior during a failover:
Session Synchronization (synced):
The most important indicator in the exhibit is the synced flag located in the state= line (state=may_dirty synced none app_ntf).
In FortiOS HA (High Availability), the synced flag confirms that this specific session has been successfully synchronized from the primary device to the secondary (backup) device.
Session synchronization (Session Pickup) ensures that if the primary unit fails, the secondary unit already has the session in its table and can resume traffic processing immediately.
TCP State (proto_state=01):
The output shows proto=6 (TCP) and proto_state=01.
In the FortiGate session table, proto_state=01 for TCP indicates that the session is in the ESTABLISHED state (post-three-way handshake).
This invalidates Option B, which claims the TCP session is not fully established.
Failover Outcome:
Because the session is ESTABLISHED and SYNCED, the secondary device will seamlessly take over the session upon primary failure.
The traffic continues to flow through the new primary without requiring the user/client to restart the connection. This is the primary function of HA Session Pickup.
Why other options are incorrect:
A: While the output shows app_ntf (Application Control notification) and may_dirty, the presence of the synced flag overrides this concern regarding failover. If the session type were not supported for failover (e.g., certain proxy sessions in older versions), it would not be marked as synced. Since it is synced, it persists.
B: As noted, proto_state=01 means established, not "not fully established".
D: While the kernel updates routing tables, the purpose of syncing the session is to preserve the state so it does not need to be re-evaluated as a new packet would, preventing traffic drops.
Reference:
FortiGate Security 7.6 Study Guide (High Availability): "If session pickup is enabled, the primary unit synchronizes its session table... to the backup unit. If the primary unit fails, the backup unit... continues to process the sessions with no interruption."
