NEW QUESTION # 138
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,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 .
NEW QUESTION # 139
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: B
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 # 140
Exhibit.
Refer to the exhibit, which shows a partial output of diagnose hardware aysinfo memory.
Which two statements about the output are true? (Choose two.)
Answer: C,D
Explanation:
The partial output from diagnose hardware sysinfo memory provides details on system RAM allocation.
According to Fortinet ' s technical documentation for memory troubleshooting and Linux memory management (which FortiOS is based on):
MemFree is the portion of physical memory not currently allocated to any running process or kernel function.
Thus, 708880 kB is available and can be immediately used by user-space programs or system operations.
Inactive refers to pages in the memory cache that were previously in use for I/O or file system buffering but are now not actively referenced. These pages are retained in memory for quick access if needed again, but can be reclaimed for other memory operations if demand increases. The value 98908 kB here represents currently unused cache pages (inactive pages), ready for repurposing or deletion if the system requires more RAM.
Cached represents the total amount of system memory allocated to cache, which includes both active and inactive cache pages. It does not, by itself, represent I/O cache exclusively, nor does " inactive " mean memory "will never be used" as the kernel can re-purpose inactive pages on demand.

NEW QUESTION # 141
Refer to the exhibits.
The system administrator settings configured on the root FortiGate and the Security Fabric settings configured on a downstream FortiGate are shown.
When prompted to sign in with Security Fabric to the downstream FortiGate, a user enters the single sign-on (SSO) provider credentials.
What happens next for the user?
Answer: C
Explanation:
The Enterprise Firewall 7.6 Administrator Study Guide explains: "The root FortiGate acts as the identity provider (IdP) and you configure the other devices as service providers (SP)." Therefore, the root FortiGate authenticates the credentials for the AdminSSO administrator, while the downstream FortiGate operates as the SAML service provider.
After successful authentication, the root FortiGate returns a SAML assertion to the downstream FortiGate.
The downstream device then grants access according to its configured SAML administrator profile. The exhibit shows that its Default admin profile is super_admin_readonly. Consequently, the user is logged in to the downstream FortiGate with read-only super-administrator privileges.
The browser can be redirected temporarily to the root FortiGate for identity-provider authentication, but that is not the final access outcome, so option A is incomplete. AdminSSO is the administrator account name, not an access profile, and the user is not left on the root FortiGate, eliminating option C. Because the credentials are successfully authenticated, option D is also incorrect.

NEW QUESTION # 142
