  1. What Aruba technology allows employees to securely access corporate resources from a RAP while simultaneously allowing family members to access only the internet via a separate SSID?

    Answer: Split Tunnel Mode with multiple SSIDs

    Split Tunnel mode on a RAP sends corporate-destined traffic through the IPsec tunnel to the controller while routing internet traffic locally, supporting simultaneous corporate and guest SSIDs.

  2. Which Aruba ClearPass component is responsible for profiling devices and determining endpoint posture before granting network access?

    Answer: ClearPass Policy Manager (CPPM)

    ClearPass Policy Manager is the core AAA and policy enforcement engine that profiles devices, evaluates posture, and enforces role-based access policies.

  3. In high-density Wi-Fi 6 deployments, OFDMA subdivides a channel into smaller resource units (RUs). What is the minimum RU size in 802.11ax?

    Answer: 26 subcarriers (2 MHz)

    The minimum OFDMA Resource Unit (RU) in 802.11ax is 26 subcarriers, approximately 2 MHz wide, allowing a single channel to serve many low-throughput clients simultaneously.

  4. Which Aruba feature automatically detects and classifies wireless clients by device type (e.g., iPhone, laptop, IoT sensor) without requiring 802.1X?

    Answer: ClearPass Device Insight / fingerprinting

    ClearPass Device Insight uses passive traffic fingerprinting, DHCP, HTTP, and mDNS attributes to automatically classify devices and assign appropriate access policies.

  5. What is the purpose of Aruba's RF Protect (WIDS/WIPS) 'tarpit' containment method?

    Answer: Slow down rogue AP clients by injecting crafted frames that force a fallback to low data rates

    Tarpit containment injects specially crafted 802.11 frames that cause rogue AP clients to fall back to very low data rates, effectively making the unauthorized connection unusable.

  6. Which Aruba network management platform is the legacy on-premises solution for monitoring and managing APs, controllers, and switches?

    Answer: AirWave

    AirWave is Aruba's on-premises network management system providing monitoring, configuration, and reporting for heterogeneous wireless and wired environments.

  7. When Aruba APs detect a valid 802.11h radar signal on a 5 GHz DFS channel, what action is required?

    Answer: Immediately evacuate the channel and remain off it for at least 30 minutes

    802.11h Dynamic Frequency Selection (DFS) mandates that upon radar detection, APs must vacate the channel within 10 seconds and observe a 30-minute non-occupancy period before reuse.
