As a network administrator, you are responsible for managing an enterprise secure wireless LAN.

The correct way to ensure that the RF channels and transmission power limits are appropriately configured for the remote APs is to create a new FortiAP profile and change the country code settings on the profile. This is because the country code settings determine the legal RF channels and transmission power limits for each country, and they are applied at the FortiAP profile level. By creating a new FortiAP profile for the remote APs, you can specify the correct country code for Germany and assign it to the APs. This will ensure that the APs comply with the local regulations and avoid interference with other devices. Configuring the APs individually by overriding the settings in Managed FortiAPs is not recommended, as it is tedious and error-prone. Configuring the controller for the correct country code for Germany is not possible, as the controller can only have one country code setting, which should match its physical location. Cloning a suitable FortiAP profile and changing the county code settings on the profile is not advisable, as it may cause conflicts with other settings that are specific to the original profile.
