  1. Which Aruba feature allows a wireless client to roam between APs without re-authenticating to the RADIUS server?

    Answer: 802.11r Fast BSS Transition

    802.11r Fast BSS Transition enables fast roaming by pre-caching keys, eliminating the need for full re-authentication with the RADIUS server on each roam.

  2. In an Aruba Mobility Controller deployment, what is the role of the Master Controller?

    Answer: It manages configuration and policies for Local Controllers

    The Master Controller centralizes configuration management and policy distribution to Local Controllers in a hierarchical deployment.

  3. What Aruba technology dynamically adjusts AP transmit power and channel selection to minimize interference?

    Answer: AirMatch

    AirMatch is Aruba's RF optimization solution that runs nightly batch algorithms to compute optimal channel and power assignments for the entire network.

  4. Which tunneling protocol does Aruba use by default to carry wireless client traffic from a Remote AP back to the Mobility Controller?

    Answer: IPsec

    Aruba Remote APs use IPsec tunnels to securely carry client traffic back to the Mobility Controller over untrusted networks.

  5. In Aruba ClearPass, what component issues 802.1X certificates to wireless devices automatically?

    Answer: ClearPass OnBoard

    ClearPass OnBoard automates device provisioning by enrolling devices and distributing 802.1X certificates for certificate-based authentication.

  6. What is the primary purpose of User-Based Tunneling (UBT) in Aruba wired/wireless integration?

    Answer: To tunnel wired switch port traffic to the Mobility Controller for policy enforcement

    UBT tunnels traffic from Aruba switches to the Mobility Controller so that the same user-role policies applied to wireless clients can be enforced for wired users.

  7. Which Aruba solution provides posture assessment to check device compliance before granting full network access?

    Answer: ClearPass OnGuard

    ClearPass OnGuard performs health checks on endpoints — verifying antivirus, firewall, patch status — and enforces posture-based access policies.
