According to the FortiAP Configuration Guide1, “Auto TX power control allows the AP to adjust its transmit power based on the signal strength of the client. The AP will measure the signal strength of the client every 30 seconds and adjust its transmit power up or down until the client signal is detected at -70 dBm.” Therefore, option A is true because it describes how the FortiAP wireless interface configures its transmission power when auto TX power control is enabled. Option B is false because FortiGate does not measure the signal strength of adjacent AP interfaces, but rather the FortiAP does. Option C is false because FortiGate does not adjust the adjacent AP power, but rather the FortiAP adjusts its own power. Option D is false becauseFortiGate does not measure the signal strength of the weakest associated client, but rather the FortiAP does.

According to the exhibit, the RADIUS server configuration on FortiGate points to FortiAuthenticator, which is acting as an authentication proxy and is configured to relay all authentication requests to a remote Windows AD server using LDAP. However, LDAP does not support MSCHAP2 authentication, which is required for RADIUS. Therefore, option A is true because on FortiAuthenticator, enabling Windows Active Directory Domain Authentication will add FortiAuthenticator to the Windows domain and allow it to use MSCHAP2 authentication with the AD server. Option C is also true because on FortiAuthenticator, changing the back-end authentication server from LDAP to RADIUS will allow it to use MSCHAP2 authentication with the AD server. Option B is false because on FortiGate, configuring the NAS IP setting on the RADIUS server will not affect the MSCHAP2 authentication, but rather the source IP address of the RADIUS packets. Option D is false because on FortiGate, updating the Secret setting on the RADIUS server will not affect the MSCHAP2 authentication, but rather the shared secret between FortiGate and FortiAuthenticator.

According to the FortiGate Administration Guide, “To use an external captive portal, you must configure a user group that uses the external captive portal as the authentication method and apply it to a firewall policy.” Therefore, option C is true because it will allow the wireless users to be redirected to the external captive portal URL when they try to access the Internet. Option A is false because disabling the user group from the SSID configuration will prevent the wireless users from being authenticated by the FortiGate device. Option B is false because enabling the captive-portal-exempt option in the firewall policy will bypass the captive portal authentication for the wireless users, which is not the desired outcome. Option D is false because including the wireless client subnet range in the Exempt Source section will also bypass the captive portal authentication for the wireless users, which is not the desired outcome.
