What happens to the Virtual Controller role in an Aruba Instant cluster if the current VC becomes unreachable?
Answer: A new VC is elected from the remaining APs automatically
Aruba Instant APs automatically elect a new Virtual Controller from remaining members, ensuring cluster continuity with no manual intervention.
In Aruba's architecture, what is the primary difference between an 'Air Monitor' and a standard access AP?
Answer: Air Monitors are dedicated to WIDS/WIPS scanning and do not serve clients
Air Monitors are APs configured exclusively for wireless intrusion detection/prevention scanning and cannot simultaneously serve client traffic.
Which Aruba feature allows controllers to be deployed as virtual machines rather than physical appliances?
Answer: VMC (Virtual Mobility Controller)
Aruba's VMC is a software-based Mobility Controller that runs on standard hypervisors (VMware, KVM), providing full controller functionality without dedicated hardware.
What is the role of 'AP groups' in Aruba Mobility Controller configuration?
Answer: Apply a common set of configuration profiles to multiple APs simultaneously
AP groups allow administrators to assign shared configuration profiles (Virtual APs, RF, SSID settings) to sets of APs without configuring each individually.
In Aruba Mobility Master architecture, which component actually terminates CAPWAP tunnels from APs?
Answer: Managed Device (MD)
Managed Devices (formerly Local Controllers) terminate CAPWAP tunnels and handle data plane forwarding, while Mobility Master handles management plane functions.
When deploying Aruba APs in a mesh topology, which AP acts as the entry point connecting the mesh to the wired network?
Answer: Mesh Portal
The Mesh Portal is the AP with a wired uplink that connects the wireless mesh network to the wired infrastructure and serves as the root of the mesh tree.
Which Aruba licensing model ties licenses to the Mobility Master rather than individual controllers, enabling flexible capacity allocation?
Answer: Centralized pool licensing via Mobility Master
Mobility Master hosts a centralized license pool that Managed Devices draw from dynamically, removing the need to assign fixed AP counts to each controller.
