Answer: A

Explanation:

Aruba’s Captive Portal uses Layer 3 authentication, which means that it intercepts the client’s HTTP requests and redirects them to a web page where the client can enter their credentials. The credentials are then verified by a RADIUS server or a local database before granting network access.
