NEW QUESTION # 56
Refer to the exhibit.
Partial output of diagnose sys session stat command is shown.
An administrator has noticed unusual behavior from FortiGate. It appears that sessions are randomly removed. Which two reasons could explain this? (Choose two.)
Answer: A,B
Explanation:
To determine why sessions are being removed, we must interpret the specific counters in the diagnose sys session stat output provided in the exhibit.
Analyze memory_tension_drop (Reason A):
Observation: The output shows memory_tension_drop=4.
This counter specifically increments when the FortiGate kernel attempts to allocate a new memory page for a session but fails due to a lack of available system memory. As a result, the session creation is aborted or an existing session is dropped to free up resources. This confirms that the kernel is struggling to allocate memory pages.
Analyze extreme_low_mem (Reason D):
Observation: The output shows extreme_low_mem=0 (which is good), but we must look at the context of memory_tension_drop.
Context: While the extreme_low_mem counter itself is 0 in this snapshot, the presence of memory_tension_drop indicates the system is under memory pressure. Furthermore, in many Fortinet exam contexts involving this specific exhibit, the focus is on the mechanism of "flushing sessions" to recover memory.
Refinement: Actually, look closer at the exhibit. It shows flush=787.
The flush counter indicates the number of times the system has actively purged (flushed) old or stale sessions from the table to recover memory or due to policy changes. A high flush count combined with memory tension drops strongly suggests the system is aggressively removing sessions to handle high memory usage. Therefore, "FortiGate is flushing sessions because of high memory usage" is the correct interpretation of the flush and memory_tension_drop counters working together.
Why other options are incorrect:
B: There is no counter in this specific output (like tcp_syn_sent drop) that indicates dropping incomplete handshakes. The clash=0 and delete=0 counters are low/zero.
C: The dev_down=16/120 field does not mean the device was down for 10 seconds. It refers to device index pointers or internal kernel interface states, not system uptime/downtime impacting session acceptance in the way described.
Reference:
FortiGate Troubleshooting Guide (System Resources): "The memory_tension_drop counter indicates sessions dropped due to kernel memory exhaustion. The flush counter indicates sessions removed to free up table space."
NEW QUESTION # 57
Refer to the exhibits.
An administrator is attempting to advertise the network configured on port3. However, FGT-A is not receiving the prefix.
Which two actions can the administrator take to fix this problem? (Choose two.)
Answer: B,D
NEW QUESTION # 58
Refer to the exhibit.
A network topology and a partial routing table are shown.
FortiGate has already been configured with a firewall policy that allows all ICMP traffic to flow from port1 to port3.
Which two changes can the administrator perform to ensure the server at 10.4.0.1/24 receives the ICMP echo reply from the laptop at 10.1.0.1/24? (Choose two.)
Answer: B,D
Explanation:
The correct answers are A and C .
The study guide describes this exact asymmetric ICMP scenario. It states:
"The server sends an echo request to the PC through port2 of the local router, effectively bypassing FortiGate. When it receives the echo request, the PC responds with an echo reply through its default gateway, 10.1.0.2, which is port1 on FortiGate. Because there is no existing session, the echo reply is dropped. All subsequent echo replies are blocked." That means the current problem exists because:
* the ICMP request bypasses FortiGate
* the ICMP reply goes through FortiGate
* FortiGate has no matching session , so it drops the reply
The study guide then shows the exact corrective option:
"Allowing asymmetric routing:"
config system settings
set asymroute enable
end
It further explains:
"After the packet passes through the FortiGate CPU, FortiGate forwards the packet using the FIB, even though there are no session matches. FortiGate forwards all subsequent echo replies using the FIB." So A is correct.
The other valid fix is to make the traffic symmetric by changing the laptop's default gateway so the reply no longer goes through FortiGate. In the exhibit, the alternate gateway is 10.1.0.254 , which is the local router on the same subnet. If the laptop uses 10.1.0.254 instead of 10.1.0.2, the ICMP echo reply follows the same bypass path as the echo request, so the server receives it without involving FortiGate session validation. This makes C correct.
Why the other options are wrong:
* B is wrong because this is not an RPF problem. The study guide explains RPF as a reverse path lookup used to validate whether a packet arrived on a legitimate interface, mainly for spoofing protection. The issue in this scenario is a missing session due to asymmetric routing , not a strict-versus-feasible RPF failure
* D is wrong because FortiGate already has the specific route 10.4.0.0/24 through port3 in the routing table shown in the exhibit, so adding a default static route to port3 is unnecessary and not the reason the echo reply is being dropped So the verified answers are: A, C .
NEW QUESTION # 59
Refer to the exhibit, which shows the port1 interface configuration on FortiGate and partial session information for ICMP traffic.
What happens to the session information if a routing change occurs that affects this session?
Answer: C
NEW QUESTION # 60
Refer to the exhibit.
The output of the command diagnose vpn tunnels liar is shown.
Which two statements accurately describe the status of the tunnel? (Choose two.)
Answer: A,C
Explanation:
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).
