ACMA Mobility Architecture & Infrastructure 5

Question 1

What happens to the Virtual Controller role in an Aruba Instant cluster if the current VC becomes unreachable?

Accepted Answer

A new VC is elected from the remaining APs automatically

Answer

Aruba Instant APs automatically elect a new Virtual Controller from remaining members, ensuring cluster continuity with no manual intervention.

Question 2

In Aruba's architecture, what is the primary difference between an 'Air Monitor' and a standard access AP?

Accepted Answer

Air Monitors are dedicated to WIDS/WIPS scanning and do not serve clients

Answer

Air Monitors are APs configured exclusively for wireless intrusion detection/prevention scanning and cannot simultaneously serve client traffic.

Question 3

Which Aruba feature allows controllers to be deployed as virtual machines rather than physical appliances?

Accepted Answer

VMC (Virtual Mobility Controller)

Answer

Aruba's VMC is a software-based Mobility Controller that runs on standard hypervisors (VMware, KVM), providing full controller functionality without dedicated hardware.

Question 4

What is the role of 'AP groups' in Aruba Mobility Controller configuration?

Accepted Answer

Apply a common set of configuration profiles to multiple APs simultaneously

Answer

AP groups allow administrators to assign shared configuration profiles (Virtual APs, RF, SSID settings) to sets of APs without configuring each individually.

Question 5

In Aruba Mobility Master architecture, which component actually terminates CAPWAP tunnels from APs?

Accepted Answer

Managed Device (MD)

Answer

Managed Devices (formerly Local Controllers) terminate CAPWAP tunnels and handle data plane forwarding, while Mobility Master handles management plane functions.
