  1. What is the purpose of the Aruba 'AP provisioning' process when a new AP boots for the first time?

    Answer: Allow the AP to discover and register with a Mobility Controller

    AP provisioning involves the AP discovering its controller via DHCP options, DNS, or ADP and then registering to receive its configuration.

  2. In Aruba infrastructure, what is 'ADP' (Aruba Discovery Protocol) used for?

    Answer: Allowing APs to discover Mobility Controllers on the same Layer 2 segment

    ADP is a Layer 2 multicast protocol that allows Aruba APs to discover controllers on the same broadcast domain during initial boot.

  3. Which forwarding mode sends all client traffic through the controller for policy enforcement before reaching the network?

    Answer: Tunnel mode

    Tunnel mode encapsulates all client traffic in GRE and sends it to the controller, ensuring centralized policy enforcement for all users.

  4. In Aruba's 'bridge mode' AP deployment, where is user traffic policy applied?

    Answer: On the AP itself using locally configured policies

    In bridge mode, APs apply firewall and policy rules locally and forward client traffic directly onto the local network without tunneling to the controller.

  5. What Aruba infrastructure feature enables multiple physical controllers to appear as a single logical controller to APs and clients?

    Answer: Controller cluster

    Aruba controller clusters present a unified control plane so APs and clients can roam freely without re-authenticating when moving between physical controllers.

  6. Which protocol does Aruba use to allow APs to advertise themselves and discover neighboring infrastructure devices?

    Answer: LLDP (Link Layer Discovery Protocol)

    Aruba APs support LLDP to communicate with neighboring switches and infrastructure devices for topology discovery and troubleshooting.

  7. In an Aruba Instant deployment (no controller), which AP takes on the role of managing the cluster?

    Answer: The Virtual Controller (VC) elected dynamically

    Aruba Instant APs elect a Virtual Controller dynamically; the VC manages configuration and policy for all APs in the cluster.
