Read the first 7 Configuration & Troubleshooting of Aruba Solutions flashcards as text

  1. An Aruba AP is configured for ARM (Adaptive Radio Management). A technician notices clients on 2.4 GHz are experiencing high interference. What ARM feature automatically moves clients to 5 GHz?

    Answer: Band Steering

    Band Steering in ARM proactively encourages dual-band clients to connect to the less congested 5 GHz band.

  2. A network admin needs to verify that an Aruba controller is correctly forwarding RADIUS authentication requests. Which command shows RADIUS server reachability and statistics?

    Answer: show aaa authentication-server radius statistics

    'show aaa authentication-server radius statistics' displays packet counts, success/failure rates, and server reachability for configured RADIUS servers.

  3. Which parameter in an Aruba SSID profile controls the maximum number of clients that can associate to a single AP radio?

    Answer: Max Clients per Radio

    The 'Max Clients per Radio' setting in the SSID or AP radio profile caps concurrent client associations per radio.

  4. During troubleshooting, an admin runs 'show datapath session table' on an Aruba controller. What does this command reveal?

    Answer: Active forwarding sessions including source/destination IPs, ports, and flags

    The datapath session table shows all active Layer 4 sessions being forwarded through the controller's datapath engine.

  5. An Aruba Instant network uses an external RADIUS server for 802.1X. After adding a second IAP to the cluster, some clients fail authentication. What is the most likely cause?

    Answer: The RADIUS server's NAS client list does not include the new IAP's IP address

    RADIUS servers authenticate NAS clients by IP; if the new AP's IP is not added as an allowed NAS client, authentication requests are rejected.

  6. What is the purpose of configuring an 'AP whitelist' on an Aruba Mobility Master?

    Answer: To restrict which APs are allowed to terminate tunnels on managed controllers

    The AP whitelist on Mobility Master ensures only pre-approved APs (by MAC or serial) can establish GRE tunnels to managed controllers.

  7. A user reports intermittent connectivity on a voice call over Wi-Fi. The admin suspects roaming issues. Which Aruba feature should be verified to ensure fast Layer 2 roaming between APs?

    Answer: 802.11r Fast BSS Transition (FT)

    802.11r Fast BSS Transition pre-authenticates clients to neighboring APs, enabling sub-50ms roaming critical for voice applications.
