Explanation
According to the FortiOS CLI Reference Guide, "The diagnose debug application foauthd command enables debugging of certificate verification process in real time." Therefore, option A is true because it describes the CLI command that an administrator should use to view the certificate verification process in real time. Option B is false because diagnose debug application radiusd -1 enables debugging of RADIUS authentication process, not certificate verification process. Option C is false because diagnose debug application authd -1 enables debugging of authentication daemon process, not certificate verification process. Option D is false because diagnose debug application fnbamd -1 enables debugging of FSSO daemon process, not certificate verification process.

Explanation
According to the exhibit, the firewall policy from port3 to port1 has no user group specified, which means that it allows all users to access the internet. Therefore, option B is true because adding RSSO Group to the firewall policy will restrict internet access to RSSO users only. Option A is false because changing the RADIUS Attribute Value setting will not affect the firewall policy, but rather the RSSO user group membership. Option C is false because enabling Security Fabric Connection on port3 will not affect the firewall policy, but rather the communication between FortiGate and other Security Fabric devices. Option D is false because creating a second firewall policy from port3 to port1 will not affect the existing firewall policy, but rather create a redundant or conflicting policy.

According to the exhibits, the AP 2.4 GHz interface is currently configured on channel 6, which is overlapping with other nearby APs on channels 4 and 8. This can cause interference and reduce the wireless performance. Therefore, changing the AP 2.4 GHz channel to 1 would improve the wireless connection, as it would avoid the overlapping channels and use a non-overlapping channel instead.

According to the FortiOS CLI Reference Guide, "The diagnose debug application foauthd command enables debugging of certificate verification process in real time." Therefore, option A is true because it describes the CLI command that an administrator should use to view the certificate verification process in real time. Option B is false because diagnose debug application radiusd -1 enables debugging of RADIUS authentication process, not certificate verification process. Option C is false because diagnose debug application authd -1 enables debugging of authentication daemon process, not certificate verification process. Option D is false because diagnose debug application fnbamd -1 enables debugging of FSSO daemon process, not certificate verification process.
