  1. When an Aruba AP operates in 'split-tunnel' mode, what traffic is sent directly to the local network without going through the controller?

    Answer: Guest or internet-bound traffic defined by policy

    In split-tunnel mode, traffic matching local breakout policies (e.g., guest internet) exits locally while corporate traffic tunnels to the controller.

  2. Which layer of the OSI model does Aruba's GRE tunnel between an AP and controller primarily operate at?

    Answer: Layer 3

    GRE tunnels between APs and controllers encapsulate Layer 2 frames within Layer 3 IP packets routed across the network.

  3. In Aruba's 'campus AP' deployment model, which device terminates 802.11 associations and processes user authentication?

    Answer: The Mobility Controller

    In campus mode, APs are lightweight and forward all 802.11 frames to the Mobility Controller, which terminates associations and enforces authentication.

  4. What Aruba feature allows APs deployed in remote offices to terminate their tunnels to a controller over the internet securely?

    Answer: Remote AP (RAP)

    Remote APs use IPsec to establish a secure tunnel to the controller across the internet, enabling home or branch office deployments.

  5. In Aruba's Virtual AP (VAP) architecture, what does each VAP map to on the physical AP?

    Answer: A distinct SSID with its own set of policies

    Each VAP represents an SSID with its own security, QoS, and forwarding policies broadcast by a single physical AP radio.

  6. Which Aruba product line is purpose-built for branch office deployments, combining switching, routing, and wireless in one device?

    Answer: Aruba 9000 Series Gateway

    The Aruba 9000 Series SD-WAN Gateways provide integrated WAN, LAN switching, and wireless termination for branch deployments.

  7. When configuring Aruba APs for a high-density environment, which AP placement strategy is most recommended?

    Answer: Reduce cell size using lower power and higher AP density

    High-density environments benefit from smaller, lower-power cells with more APs to handle more concurrent clients per radio.
