ACMA Mobility Architecture & Infrastructure 4

Question 1

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

Accepted Answer

Allow the AP to discover and register with a Mobility Controller

Answer

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

Question 2

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

Accepted Answer

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

Answer

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

Question 3

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

Accepted Answer

Tunnel mode

Answer

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

Question 4

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

Accepted Answer

On the AP itself using locally configured policies

Answer

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

Question 5

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

Accepted Answer

Controller cluster

Answer

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