NEW QUESTION # 96
What can cause an IKEv2 tunnel to go down after it was initially brought up successfully?
Answer: D
Explanation:
The correct answer is D .
The study guide explains that IKEv2 has two initial exchanges:
* IKE_SA_INIT
* IKE_AUTH
and then later exchanges such as:
* CREATE_CHILD_SA
It also states the roles of those exchanges:
* IKE_SA_INIT negotiates the security settings for IKE traffic
* IKE_AUTH performs mutual authentication and sets up the piggyback child SA
* CREATE_CHILD_SA creates a new child SA or rekeys an existing child SA Most importantly, the study guide explicitly says:
"By IKEv2 design, no Diffie-Hellman public key is exchanged during an IKE_AUTH exchange.
Consequently, any phase 2 Diffie-Hellman group configuration mismatch between FortiGate and the peer is experienced only during the first rekey (CREATE_CHILD_SA exchange) of the child SA created during IKE_AUTH." This proves the key idea behind the question: an IKEv2 tunnel can come up successfully first, then fail later during a CREATE_CHILD_SA rekey/renegotiation event because of a phase 2 mismatch. Among the provided options, the matching later-stage cause is mismatched quick-mode selectors during CREATE_CHILD_SA .
Why the other options are wrong:
* A is wrong because if the proposal mismatch were in the initial negotiation path, the tunnel would fail during establishment, not after it was already up. The study guide places initial tunnel establishment in IKE_SA_INIT and IKE_AUTH
* B is wrong because a mismatch in IKE_SA_INIT affects the initial establishment stage, not a tunnel that was already brought up successfully
* C is wrong because a pre-shared key mismatch is part of authentication during IKE_AUTH , so the tunnel would not come up successfully in the first place
NEW QUESTION # 97
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,D
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).
NEW QUESTION # 98
Refer to the exhibit.
If the default settings are m place, what can you conclude about the conserve mode shown in the exhibit?
Answer: D
Explanation:
The exhibit shows:
* memory conserve mode: on
* memory used: 2706 MB 89% of total RAM
* memory used threshold red: 2675 MB 88% of total RAM
* memory used + freeable threshold extreme: 2887 MB 95% of total RAM
The study guide states that the default thresholds are:
* Extreme = 95%
* Red = 88%
* Green = 82%
So this FortiGate is in conserve mode because memory usage is 89% , which is above the red threshold (88%) , but it has not yet reached the extreme threshold (95%) .
The study guide then explains exactly what happens during conserve mode:
"For traffic that requires proxy-based inspection (and if memory usage has not exceeded the extreme threshold):
config system global
set av-failopen [off | pass | one-shot]
pass (default): All new sessions pass without inspection"
It also says:
"The av-failopen setting also applies to flow-based antivirus inspection." And the same page adds:
"If memory usage exceeds the extreme threshold, all new sessions that require inspection (flow-based or proxy-based) are blocked." Therefore, with default settings and with memory usage below the extreme threshold , FortiGate is allowing new sessions that require inspection, but bypassing inspection . That matches C .
Why the other options are wrong:
* A is wrong because the default behavior is not to block proxy-based inspected sessions; the default is pass , meaning they pass without inspection
* B is wrong because if memory rises another 6% , it reaches 95% , which is the extreme threshold . At that point, the study guide says all new sessions that require inspection are blocked
* D is wrong because FortiGate blocks all new inspected sessions only when memory usage exceeds the extreme threshold , and the exhibit shows it is currently at 89% , not 95%
NEW QUESTION # 99
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: B
NEW QUESTION # 100
Which of the following regarding protocol states is true? (Choose one answer)
Answer: C
Explanation:
The correct answer is B .
The study guide states that for TCP , the protocol state is a two-digit number . The first digit is the server- side state and is 0 when the session is not subject to inspection . The second digit is the client-side state .
It also shows that value 1 = ESTABLISHED
So, for a normal TCP session with no inspection, proto_state=01 means:
* first digit 0 = no inspection
* second digit 1 = ESTABLISHED
That makes B correct.
Why the other options are wrong:
* A is wrong because for UDP , the study guide says 00 = one-way traffic and 01 = two-way traffic
* C is wrong because 10 does not represent the normal established TCP session described in the study guide. The established example shown is based on state value 1 , and the guide explicitly highlights proto_state=11 when both server-side and client-side TCP handshakes are completed
* D is wrong because for ICMP , the study guide says "the protocol state is always 00"
