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

  1. An Aruba IAP cluster Virtual Controller IP is not reachable from the wired network. The IAP uplink is connected to an access port on VLAN 1. What is the most likely issue?

    Answer: The Virtual Controller IP is not on the same subnet as VLAN 1 or no default gateway is configured

    If the Virtual Controller IP is not within the AP management subnet or lacks a gateway, it will be unreachable from other network segments.

  2. What is the role of the 'conductors' (formerly master) and 'members' hierarchy in ArubaOS 8 Mobility Master architecture?

    Answer: Mobility Master acts as the central policy manager while Managed Devices handle data plane forwarding

    In ArubaOS 8, Mobility Master centralizes configuration and policy management while Managed Devices (controllers) handle local data plane forwarding for connected APs.

  3. A technician is configuring a captive portal on an Aruba controller. Users are redirected to the portal page but cannot reach the login page. What firewall rule must be present in the pre-authentication role?

    Answer: Permit DNS and HTTP/HTTPS to the captive portal server

    Pre-authentication roles must allow DNS resolution and HTTP/HTTPS access to the captive portal server so users can reach the login page before authenticating.

  4. An admin needs to collect a packet capture on an Aruba AP for client troubleshooting. Which ArubaOS feature enables capturing wireless frames directly on the AP?

    Answer: AP Packet Capture using 'ap packet-capture' CLI command

    ArubaOS supports on-AP packet capture via the 'ap packet-capture' CLI, allowing admins to capture 802.11 frames directly at the AP without additional hardware.

  5. In Aruba ClearPass Policy Manager, what is the function of an 'Enforcement Profile'?

    Answer: It defines the RADIUS attributes or actions returned to the NAD after a policy evaluation

    An Enforcement Profile in ClearPass defines the RADIUS VSAs, CoA actions, or VLAN assignments that are sent back to the Network Access Device after policy evaluation.

  6. A client cannot connect because the controller log shows 'association denied: max clients reached'. What is the recommended solution?

    Answer: Increase the max clients per radio limit or enable load balancing across APs

    When the maximum client threshold is reached, either raising the limit in the AP profile or enabling ARM/Client Match load balancing to distribute clients across APs resolves the issue.

  7. Which Aruba tool provides a graphical real-time RF visualization showing channel utilization, AP coverage, and client distribution across a floor plan?

    Answer: Aruba Central RF Dashboard or AirWave RF VisualRF

    Aruba Central's RF Dashboard and AirWave's VisualRF module provide graphical floor plan views with real-time RF health, channel utilization, and client distribution overlays.
