NSE7_FSN_AR-7.6 Practice Questions

The SD-WAN 7.6 Enterprise Administrator Study Guide identifies the recommended BGP-on-loopback IPsec settings. For branches, it specifies:

“Static tunnel type (remote end IP address is known).”

“net-device enable.”

Enabling net-device on the spoke creates a kernel interface for the tunnel. This assists with tunnel monitoring and management and is required to support ADVPN shortcut tunnels. Dynamic BGP establishes on-demand BGP peerings between spokes after an ADVPN shortcut is created; therefore, the spoke must support those dynamic shortcut interfaces. This makes option C correct.

The spoke should also configure localid. The FortiOS 7.6 Administrator Study Guide explains: “Local ID: if the peer accepts a specific peer ID, type that same peer ID in this field.” The local ID supplies the spoke’s IKE identity to the dial-up hub, allowing the hub to identify and authenticate the connecting spoke correctly. Therefore, option D is correct.

Option A reverses the recommended roles. The hub must use a dynamic tunnel type because it operates as the dial-up server and does not require every spoke’s changing public gateway address in advance.

Option B is also incorrect. The guide states: “There is no need to configure any tunnel IP address, so the IKE Mode Config is not used.” BGP on loopback uses the loopback address and exchange-interface-ip instead of IKE mode configuration.

The correct answers are B and C .

The study guide has a section titled “Not Verified Status on the Collector Agent” and states:

“The collector agent cannot verify if the user is still logged in” and lists these common causes :

“A firewall is blocking traffic to port 139 and 445”

“The workstation remote registry service is not running”

The guide also explains the verification method:

“For WMI polling mode, the collector agent checks the WMI service. For all the other modes, the collector agent checks the HKEY_USERS hive through remote registry services.” If the workstation does not respond to these checks, the status can become not verified

An additional requirements slide in the same study guide confirms:

“TCP ports 139 and 445 must be open between the collector agent and all workstations”

“Remote registry service must be up and running on each workstation”

Why the other options are wrong:

A is wrong because the study guide mentions a workstation coming out of hibernate mode under a different problem: “No Internet After IP Address Change” , not as a common cause of Not Verified status

D is wrong because DNS resolution issues are also discussed under the IP address change scenario, where the collector agent uses DNS to resolve the workstation name after an IP change. That is separate from the Not Verified causes listed for this log message

So the verified answers are: B, C .

The correct answers are B and C . The session table output clearly shows policy_id=1 , which means the traffic matched firewall Policy ID 1 . That directly validates option B . The output also shows NPU-related offload indicators, including npu_state=... ips_offload and npu info: ... offload=8/8, ips_offload=1/1 . These fields indicate that the session has been offloaded to hardware, so option C is correct. The study guide explains that FortiGate can offload sessions to network processors after session establishment, allowing subsequent packets to bypass normal CPU/kernel processing for improved performance. It also states that offloaded sessions are handled by the network processor rather than the CPU path.

Option A is too specific and is not proven by the exhibit. The output shows NPU offload, but it does not explicitly identify the hardware as NP7. Do not assume NP7 unless the platform or output confirms it. Option D is wrong because the VLAN-related fields show vlan=0x0000/0x0000 and vtag_in=0x0000/0x0000, which means the traffic is not VLAN-tagged.

The correct answers are C and D .

The study guide states: “SSL certificate inspection relies on extracting the FQDN of the URL from either: TLS extension server name indication (SNI), SSL certificate common name (CN).” It also says: “When using SSL certificate inspection, FortiGate is not decrypting the traffic. It is only inspecting the server digital certificates and the SNI field, which are interchanged before the encryption.”

This proves the second part of the answer:

under SSL certificate inspection , FortiGate does not decrypt the traffic

therefore, if the traffic is allowed , it still passes without decryption

That makes D correct.

For the SNI mismatch behavior, the FortiOS administration guide describes the default Server certificate SNI check behavior as:

“Enable: If it is mismatched use the CN in the server certificate for URL”

So if the SNI does not match the CN or any SAN, FortiGate falls back to using the CN from the Subject field for URL handling under the default setting. That makes C correct.

Why the other options are wrong:

A is wrong because with the default SNI-check behavior, when the SNI mismatches the certificate identity, FortiGate does not continue using the mismatched SNI . Instead, it uses the CN in the server certificate for the URL .

B is not the best answer in this single pair selection . While certificate inspection does not decrypt traffic, the key default behavior the documents explicitly highlight for this mismatch case is:

use the CN when SNI mismatches , and

certificate inspection does not decrypt allowed HTTPS traffic .

So the verified answers are: C, D .
