ACMA Mobility Architecture & Infrastructure 2

Question 1

Which Aruba component acts as the central policy enforcement point in a campus WLAN deployment?

Accepted Answer

Aruba Mobility Controller

Answer

The Aruba Mobility Controller enforces security policies, manages RF, and terminates client tunnels in a campus deployment.

Question 2

In Aruba's hierarchical controller architecture, what is the role of a Master Controller?

Accepted Answer

Manages configuration and coordinates Local Controllers

Answer

The Master Controller pushes configuration to Local Controllers and coordinates network-wide policy and mobility.

Question 3

What protocol do Aruba APs use to communicate with the Mobility Controller in a tunnel mode deployment?

Accepted Answer

CAPWAP

Answer

Aruba APs use CAPWAP (Control And Provisioning of Wireless Access Points) to communicate control and data traffic to the controller.

Question 4

Which Aruba AP operating mode allows the AP to function without an active controller connection by caching configuration locally?

Accepted Answer

Survivability mode

Answer

Survivability mode lets APs continue servicing clients using a cached configuration when the controller becomes unreachable.

Question 5

In an Aruba cluster deployment, what is the primary benefit of controller clustering?

Accepted Answer

Enables seamless client roaming and load sharing across controllers

Answer

Aruba controller clustering enables zero-downtime roaming and distributes AP and client load across multiple controllers.
