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

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

Answer: Survivability mode

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

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

Answer: Enables seamless client roaming and load sharing across controllers

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

Which Aruba architecture uses a cloud-managed approach where all configuration and visibility are handled via a SaaS platform?

Answer: Aruba Central architecture

Aruba Central is the cloud-native SaaS platform for managing APs, switches, and gateways without on-premises controllers.
