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.

EAP-TLS is the most secure EAP method. It requires a digital certificate on both the server end and the client end. The server and client authenticate each other using their certificates.

Explanation
According to the exhibit, the network topology and SSID settings show that FortiGate is configured to use an external captive portal hosted on FortiAuthenticator, which is connected to a Windows AD server for user authentication. However, wireless users are not able to see the captive portal login page, which means that they are not redirected to the external captive portal URL. Therefore, option B is true because adding the FortiAuthenticator and WindowsAD address objects as exempt destinations services will allow the wireless users to access the external captive portal URL without being blocked by the firewall policy. Option A is false because enabling NAT in the firewall policy with the ID 13 will not affect the redirection to the external captive portal URL, but rather the source IP address of the wireless traffic. Option C is false because enabling the captive-portal-exempt option in the firewall policy with the ID 12will bypass the captive portal authentication for the wireless users, which is not the desired outcome. Option D is false because removing the guest.portal user group in the firewall policy with the ID 12 will prevent the wireless users from being authenticated by FortiGate, which is required for accessing the external captive portal.

Explanation
According to the FortiAP Configuration Guide, "To perform RADIUS-authenticated dynamic VLAN allocation, the RADIUS server must supply the following RADIUS attributes: Tunnel-Private-Group-ID, which specifies the VLAN ID to assign to the user. Tunnel-Type, which specifies the tunneling protocol used for the VLAN. The value must be 13 (VLAN). Tunnel-Medium-Type, which specifies the transport medium used for the VLAN. The value must be 6 (802). Therefore, options A, D, and E are true because they describe the RADIUS attributes that must be supplied by the RADIUS server to enable successful VLAN allocation.
Option B is false because Tunnel-Pvt-Group-ID is not a valid RADIUS attribute name, but rather a typo for Tunnel-Private-Group-ID. Option C is false because Tunnel-Preference is not a required RADIUS attribute for dynamic VLAN allocation, but rather an optional attribute that specifies the priority of the VLAN.
