Question 21

Which device acts as the virtual controller in Instant APs?

1. Core network switch
2. External gateway appliance
3. One elected access point
4. Remote cloud server

Correct Answer: 3

Explanation:

Within an Aruba Instant wireless network deployment, physical hardware controllers are entirely eliminated because virtual controller intelligence is embedded directly into the access points. When an Instant AP cluster powers on, the access points communicate using specialized clustering protocols to dynamically elect one member to assume the virtual controller role. This elected access point manages configuration synchronization, firmware upgrades, and client roaming across the entire cluster. If the primary elected access point experiences a failure or disconnects, another AP instantly takes over the role, ensuring high availability and seamless wireless management.
