NEW QUESTION # 172
Refer to the exhibit.
The exhibit shows a session entry. Which statement about this TCP session is true?
Answer: D
Explanation:
The correct answer is C. The session is offloaded using NPU.
The exact session example in the study guide shows:
proto=6 # this is a TCP session
expire=3599 # the session will expire in 3599 seconds, not in one second hook=post dir=org act=snat 10.9.31.117:45388- > 200.8.57.5:443(10.1.0.3:45388) hook=pre dir=reply act=dnat 200.8.57.5:443- > 10.1.0.3:45388(10.9.31.117:45388) npu info: ... offload=8/8 ...
and the slide explicitly states: "Offloaded in both directions using NP6" The study guide also explains this exact point clearly:
"Counters for hardware acceleration-The presence of the npu info field indicates the session has been offloaded to hardware acceleration. In this example, traffic is being offloaded in both directions using network processor (NP) 6, which is represented by the value of 8." Why the other options are wrong:
A is wrong because expire=3599, not 1. The duration=1 field means the session has existed for 1 second, not that it will expire in 1 second.
B is wrong because the original session is from 10.9.31.117 to the remote server 200.8.57.5:443. The IP
10.1.0.3 is the SNAT-translated source address, not the final destination.
D is not the best answer for this single-select question. The reply is indeed DNATed back toward the original client, but the exact validated takeaway highlighted by the study guide for this exhibit is the NPU offload state.
NEW QUESTION # 173
Refer to the exhibit.
The partial output of diagnose sys session stat command is shown.
Which statement about the output shown in the exhibit is correct?
Answer: D
Explanation:
The correct answer is C .
The exhibit shows:
* 562 in ESTABLISHED state
* 27 in CLOSE state
* memory_tension_drop=0
* ephemeral=0/131072
According to the study guide, for TCP sessions: "The protocol state in the session table is a two-digit number. For TCP, the first number (from left to right) is related to the server-side state and is 0 when the session is not subject to any inspection (flow or proxy)... The second digit is the client-side state." The same page also shows that value 1 = ESTABLISHED So, if a TCP session is in ESTABLISHED state and there is no inspection , its proto_state is 01 :
* first digit 0 = no inspection
* second digit 1 = ESTABLISHED
That makes C correct. This is also consistent with FortiOS examples showing established TCP sessions with proto=6 proto_state=01 Why the other options are wrong:
* A is wrong because the field that indicates sessions dropped due to low free memory is memory_tension_drop, and in the exhibit it is 0 , not 113. The study guide states: "If there is a lack of free memory, the kernel deletes the oldest sessions. The command shown on this slide displays the number of sessions the kernel deleted because of this mechanism." So 113 is the clash value, not memory-tension drops.
* B is wrong because ephemeral=0/131072 does not mean 131072 ephemeral sessions were recorded.
The study guide explains that FortiGate "sets a hard limit on the maximum number of ephemeral sessions that can exist at the same time in the session table." Therefore:
* 0 = current ephemeral sessions
* 131072 = maximum allowed ephemeral sessions for that model/context
* D is wrong because the study guide says the temporary retention for possible out-of-order packets happens in state value 5 (TIME_WAIT) : "When a session is closed by both the sender and receiver, FortiGate keeps that session in the session table for a few seconds, to allow for any out- of-order packets that might arrive after the FIN/ACK packet. This is the state value 5." But the exhibit shows 27 in CLOSE state , and the same table shows CLOSE = 6 , not TIME_WAIT So the verified answer is C .
NEW QUESTION # 174
Refer to the exhibit.
The routing table information is shown.
Assuming a default configuration, which three statements about the RPF check on FortiGate are correct? (Choose three.)
Answer: C,D,E
Explanation:
The correct answers are A, D, and E. This is a feasible path RPF check scenario. In FortiGate's default RPF behavior, FortiGate checks whether the routing table contains a valid return route to the source IP address through the same interface on which the packet arrived. The study guide's RPF feasible path example states that FortiGate "checks the routing table for a route that matches the source address and incoming interface of the first original packet." It then gives the exact result: User A passes because "there is a default route through wan1," so packets received on wan1 pass the RPF check regardless of source address. User B fails because FortiGate does not have a route to 95.56.234.24 through wan2. User C fails because FortiGate does not have a route to 10.0.4.63 through port1. Therefore, option B is wrong because FortiGate is not allowing asymmetric return routing here. Option C is wrong because the default route points out wan1, not port1, so it cannot validate User C's packet arriving on port1.
NEW QUESTION # 175
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: A,B
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 # 176
What is the correct order of the IKEv2 request-and-response protocol?
Answer: A
Explanation:
The Internet Key Exchange version 2 (IKEv2) protocol simplifies the negotiation process compared to IKEv1.
It is defined by a specific sequence of message exchanges to establish a secure IPsec tunnel.
The correct chronological order of the IKEv2 exchanges is:
IKE_SA_INIT (Initial Exchange):
This is the first exchange. It negotiates the security parameters for the IKE Security Association (IKE SA), sends nonces, and performs the Diffie-Hellman key exchange. At the end of this exchange, the communication is encrypted, but the peers are not yet authenticated.
IKE_AUTH (Authentication Exchange):
This is the second exchange. It authenticates the previous messages, exchanges identities and certificates (if used), and establishes the first Child SA (the actual IPsec Security Association used for data traffic).
CREATE_CHILD_SA (Subsequent Exchanges):
This exchange occurs after the IKE SA and the initial Child SA are established. It is used to create additional Child SAs (for different traffic selectors) or to perform re-keying for the IKE SA or existing Child SAs.
Why other options are incorrect:
A & B: Incorrect because CREATE_CHILD_SA cannot happen before the SA is initialized (IKE_SA_INIT) and authenticated (IKE_AUTH).
D: Incorrect because IKE_AUTH cannot occur before IKE_SA_INIT.
Therefore, the protocol flow is IKE_SA_INIT $\rightarrow$ IKE_AUTH $\rightarrow$ CREATE_CHILD_SA.
