問題 #85
Refer to the exhibits, which show the firewall policy and an antivirus profile configuration.
Why is the user unable to receive a block replacement message when downloading an infected file for the first time?
答案：D
解題說明：
In Flow Based scanning, if a virus is detected, the final packet is dropped making the file unusable tot the end user. FG caches the URL of the file. If the user attempts to download again, rather than scanning the file again, the IPS engine then sends a block message to the user.
問題 #86
Refer to the exhibit.
A RADIUS server configuration is shown.
An administrator added a configuration for a new RADIUS server While configuring, the administrator enabled Include in every user group What is the impact of enabling Include in every user group in a RADIUS configuration?
答案：B
解題說明：
Based on the FortiOS 7.6 Authentication and User Group documentation, the correct answer is A.
Meaning of "Include in every user group" (FortiOS 7.6)
When configuring a RADIUS server on FortiGate, enabling Include in every user group has a very specific and documented effect:
The configured RADIUS server object is automatically added to all FortiGate user groups.
As a result, any user who successfully authenticates against that RADIUS server becomes a valid member of every FortiGate user group, unless additional group filtering (such as RADIUS attributes) is applied.
This simplifies configuration when the same external authentication source must be accepted across multiple firewall policies that reference different user groups.
This behavior is explicitly described in the FortiOS 7.6 Administrator Guide under RADIUS authentication servers and user groups.
Why Option A is Correct
FortiGate user groups can include:
Local users
LDAP servers
RADIUS servers
Enabling Include in every user group causes FortiGate to:
Insert the RADIUS server into all existing and future FortiGate user groups Therefore, all users authenticating via this RADIUS server are implicitly allowed in every FortiGate user group.
This is exactly what option A describes.
Why the Other Options Are Incorrect
B: FortiGate does not push users or groups into the RADIUS server. Authentication is always initiated by FortiGate toward RADIUS.
C: FortiGate does not manage or modify RADIUS-side group definitions.
D: LDAP and RADIUS user groups are separate authentication mechanisms; this setting does not merge or affect LDAP groups.
問題 #87
Refer to the exhibit showing a debug flow output.
Which two conclusions can you make from the debug flow output? (Choose two.)
答案：A,D
解題說明：
The default gateway is configured on port2 → The debug output shows find a route:
flag=00000000 gw-0.0.0.0 via port2, which indicates that the default route (0.0.0.0/0) points out port2.
The matching firewall policy denies the traffic → The log line Denied by forward policy check (policy 2) confirms that policy 2 matched and explicitly dropped the traffic.
問題 #88
You are encountering connectivity problems caused by intermediate devices blocking IPsec traffic.
In which two ways can you effectively resolve the problem? (Choose two.)
答案：A,D
解題說明：
The training is basically trying to point out the advantage of FortiGate's SSL VPN over IPSec VPN in situation where issues are caused by an intermediate device.
IPsec uses ESP and UDP 500 and 4500, so where these are blocked, SSL VPN tunnel mode shines because it uses HTTPS (443) and TLS by default (both TCP).
Again where UDP ports are blocked, SSL VPN shines (Tunnel mode Hub and Spoke) because it does not use UDP.
問題 #89
Refer to the exhibit.
Which two statements about the FortiGuard connection are true? (Choose two.)
答案：B,D
解題說明：
Based on the diagnose debug rating output provided in the exhibit and the standard behavior of the FortiGuard connection mechanism in FortiOS 7.6:
Weight Calculation (Statement A is True):
In FortiOS, the rating server selection process uses a weight-based system.
According to official documentation, the weight increases with failed packets (lost responses) and decreases with successful packets.
This mechanism ensures that servers with poor reliability are penalized by having higher weights, effectively pushing them to the bottom of the preference list.
Default Port Communication (Statement D is True):
The exhibit explicitly shows the communication is using HTTPS on port 8888.
In FortiOS 7.6 (and legacy versions like 6.2/6.4), FortiGuard filtering supports specific protocols and ports:
HTTPS on ports 443, 53, and 8888, where 8888 is considered a default port for FortiGuard queries.
Ports 53 and 8888 are standard for both UDP and TCP/HTTPS FortiGuard communications to avoid common firewall blocks on standard web ports.
Why other options are incorrect:
Statement B (Unreliable protocols): While you can configure UDP (which is unreliable), the exhibit specifically shows HTTPS is being used, which is a reliable (TCP-based) protocol.
Statement C (DNS lookup): In the " Flags " column of the server list, a server found via DNS lookup would be marked with the " D " flag. The exhibit shows the flag as " I " (indicating the last INIT request was sent to this server) and a numeric " 2, " but the " D " flag is absent. Additionally, the IP 10.0.1.241 is a private address, suggesting it is a manually configured FortiManager or local override server rather than a public server found via global DNS lookup.
