The get router info bgp summary output lists BGP neighbor status:
Prefix Reception: The "State/PfxRcd" column shows the number of prefixes received from the neighbor-neighbor 100.64.1.254 has "1", confirming option A.
Received Message Count: Under "MsgRcvd", 18 packets have been received from neighbor 100.64.1.254. This matches option C.
The second neighbor 100.64.2.254 is in "Active" state and has received/sent 0 packets, indicating that its TCP connection is NOT established, disproving option B.
There is no indication anywhere that the router is "still calculating" prefixes; "Active" just means no session is established, so option D is incorrect.

The correct answers are C and D .
The key clue is the command itself:
diagnose debug application fssod -1
The study guide explicitly states: "There is a specific FortiGate daemon that handles the polling mode. It is the fssod daemon. To enable agentless polling mode real-time debug use the command: diagnose debug application fssod -1." That directly proves D. FSSO is using agentless polling mode to detect logon events .
The study guide also states: "In agentless polling mode, FortiGate frequently polls all workstations (as a standalone collector agent does) to check which users are still logged in. You can sniffer this traffic on port 445." That directly proves C. FortiGate is frequently polling the workstation in case the user has logged out .
Why the other options are wrong:
* A is wrong because the "cannot verify if the user is still logged in" / Not Verified condition is described for the collector agent workstation status, not as a conclusion from this FortiGate fssod debug line. The study guide says: "A user goes to not verified status when they log out, or when there is a problem in the polling done by the collector agent to the workstation."
* B is wrong because DC Agent mode is part of agent-based FSSO , where DC agents send events to a collector agent. This output is from the fssod daemon, which the study guide ties to agentless polling mode , not DC Agent mode.
* E is wrong because TCP port 8000 is used for communication between the collector agent and FortiGate , while in agentless polling mode FortiGate polls workstations and that traffic can be sniffed on TCP port 445 .
So the verified answers are: C, D .

Based on the Fortinet FCSS - Network Security 7.6 documents and the analysis of the VPN tunnel exhibit, here is the verified answer.
Questions no: 91
Verified Answer: A, C
Comprehensive and Detailed Explanation with all FCSS - Network Security 7.6 documents:
To determine the status of the VPN tunnel, we must examine the specific counters and fields in the diagnose vpn tunnel list output provided in the exhibit.
Analyze Phase 2 Status (Option A):
The output displays child_num=0.
In IKEv2 (and IKEv1 implementations in FortiOS), "Child SAs" refer to the Phase 2 (IPsec) Security Associations that carry the actual data traffic.
A value of 0 indicates that no Phase 2 tunnels are established. If Phase 2 were up, child_num would be at least 1.
Additionally, under the proxyid section, the field sa=0 confirms there is no active Security Association for that traffic selector.
Analyze Traffic Status (Option C):
The stat line shows: rxp=0 txp=0 rxb=0 txb=0.
rxp (Received Packets) and txp (Transmitted Packets) are both zero. This definitively confirms that no traffic is traversing the tunnel currently. This is expected since Phase 2 is down.
Analyze Phase 1 Status (Why B is incorrect):
The tunnel entry exists in the list with a valid tun_id, and NAT-Traversal is active (natt: mode=keepalive).
The presence of the tunnel in this command output, along with active Keepalive mechanisms, typically indicates that Phase 1 (IKE SA) is established and the peers are communicating on port 4500 (NAT-T), even though the data tunnels (Phase 2) failed to negotiate. If Phase 1 were down, the tunnel would often not appear in this "list" view or would show different status flags indicating a complete connection failure.
Conclusion: The exhibit shows a scenario where the Phase 1 control channel is likely up (evidenced by the entry existence and NATT keepalives), but the Phase 2 data channel is down (child_num=0), resulting in zero traffic flow (rxp=0/txp=0).

The 8.8.8.8/32 route is visible in the OSPF database on FGT-B but not installed into the routing table-the most likely explanation is that FGT-B is filtering it from being installed.
