NEW QUESTION # 23
A VPN tunnel is up. To monitor traffic flow, the administrator enters the following CLI commands on an SSH session on FortiGate:
# diagnose debug enable
# diagnose sniffer packet any ' udp and port 500 ' 4
However, the sniffer does not show any output. Assuming default configuration values, what are two possible reasons there is no output? (Choose two answers)
Answer: A,D
Explanation:
The correct answers are A and B .
The study guide says:
"If NAT-T is enabled, and there is a FortiGate located in the middle that is running NAT, the sniffer command must use a different filter. In this case, IKE traffic uses UDP port 500, but switches to UDP port 4500 during the tunnel negotiation. Additionally, ESP traffic is encapsulated inside the UDP 4500 channel." It also says:
"In some networks, UDP is blocked by firewalls or ISPs. In those cases, you can configure your VPN tunnel to use IKE over TCP in the phase 1 configuration. The default IKE TCP port is 443..." And the study guide gives the correct capture examples:
* No NAT: host < remote-gw > and udp port 500
* With NAT and NAT-T: host < remote-gw > and (udp port 500 or udp port 4500) So:
* B is correct because with NAT Traversal enabled , the tunnel may no longer be using only UDP 500 .
It can move to UDP 4500 , so the current filter may miss the traffic.
* A is correct because the filter may need to be expanded to include UDP 4500 for NAT-T, or TCP 443 when IKE over TCP is used.
Why the other options are wrong:
* C is wrong because restricting the filter to the remote peer IP can make the capture more precise, but it is not required for the sniffer to display output. The problem here is the port/protocol choice , not the lack of a host filter. The study guide examples use host filtering as an aid, not as a requirement.
* D is wrong because diagnose debug enable is used to enable real-time debug output for applications, but it does not suppress or invalidate sniffer output . Sniffer capture is a separate command path.
Fortinet documentation separately documents diagnose sniffer packet ... for packet capture and diagnose debug enable for debug features.
So the verified answers are: A, B .
NEW QUESTION # 24

NGFW-1 and NGFW-2 have been up for a week.

NEW QUESTION # 25
Refer to the exhibit.
The administrator did not override the FortiGuard FODN or IP address in the FortiGate configuration Which IP address did FortiGate get when resolving the servicem,fortiguard.net name?
Answer: A
Explanation:
The study guide explicitly explains the FortiGuard flags shown by diagnose debug rating:
D = Default
"IP addresses of servers received from DNS resolution"
It then clarifies even more specifically:
"D = The IP address FortiGate got when resolving the service.fortiguard.net name (usually two or three servers have this flag, if the administrator didn ' t overwrite the FortiGuard FQDN or IP address in the FortiGate configuration)" In the exhibit, among the answer choices, the IP address marked with the D flag is 208.91.112.194. Therefore, that is the IP FortiGate got from resolving service.fortiguard.net.
Why the other options are wrong:
B). 209.22.147.36 is not the correct choice because in the exhibit it is not the DNS-resolution entry identified by the D flag C). 64.26.151.37 has no D flag D). 96.45.33.65 has no D flag So the verified answer is: A.
NEW QUESTION # 26
Refer to the exhibit, which shows the partial output of a diagnose command.
Which two conclusions can you draw from the output shown in the exhibit? (Choose two.)
Answer: A,B
Explanation:
The study guide identifies this exact output as an expectation session created by the FTP session helper :
* "run helper-ftp" indicates the FTP helper is in use.
* "FortiGate created an expectation session and opened the pinhole port for the expected return traffic" It also explains why this exists:
* "Another important function of the session helper is to temporarily create an expected session (or pinhole) for the data channel connection that comes from the server."
* "The session helper automatically creates the session and opens the door for the incoming connection."
* "These incoming TCP sessions use random TCP port numbers."
That directly proves C is correct.
For A , the exhibit shows expire=23. The study guide explains the expire field as the length of time until the session expires if no matching traffic arrives, and the FortiOS guide states for expectation sessions:
* "Expectation sessions usually have a timeout value of 30 seconds. If the communication from the server is not initiated within 30 seconds the expectation session times out and traffic will be denied." So with expire=23, FortiGate will allow that expected traffic only for the remaining 23 seconds; after that, it times out and the traffic is denied. That makes A correct.
Why the other options are wrong:
* B is not supported . The study guide describes expectation sessions as being created by the session helper from the control-session negotiation, not as independent objects unaffected by the master session.
* D is wrong as stated. Even though the output contains policy_id=25, the study guide explicitly says the incoming expected connection is allowed by the expected session itself, "even when no firewall policy allows it."
NEW QUESTION # 27
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,C
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 .
