  1. Which Aruba technology uses 6 GHz band spectrum introduced in Wi-Fi 6E to deliver additional non-overlapping channels?

    Answer: Wi-Fi 6E extending 802.11ax into the 6 GHz band

    Wi-Fi 6E extends the 802.11ax standard into the newly opened 6 GHz band, providing up to 1,200 MHz of additional spectrum with 59 non-overlapping 20 MHz channels in the US.

  2. In Aruba's Adaptive Radio Management (ARM), what does 'Band Steering' accomplish?

    Answer: Moves clients from 2.4 GHz to 5 GHz to reduce congestion

    Band Steering nudges dual-band capable clients toward the less congested 5 GHz band by withholding probe responses on 2.4 GHz until thresholds are met.

  3. What role does a Mobility Master (MM) serve in an Aruba hierarchical controller architecture?

    Answer: Serves as the top-level licensing and configuration entity managing Mobility Controllers

    The Mobility Master sits at the top of the hierarchy, managing licenses, global configuration, and firmware for all managed Mobility Controllers.

  4. Which Aruba security feature detects and contains rogue APs by sending de-authentication frames to clients connected to unauthorized devices?

    Answer: Wireless Intrusion Protection (WIP) Containment

    Aruba's Wireless Intrusion Protection containment uses targeted de-authentication frames to disconnect clients from rogue or interfering APs.

  5. When configuring WPA3-Enterprise on an Aruba AP, which protocol provides the required 192-bit security mode?

    Answer: GCMP-256 with Suite B cryptography

    WPA3-Enterprise 192-bit mode uses GCMP-256 for encryption and Suite B (CNSA) cryptographic algorithms mandated for high-security environments.

  6. An Aruba Instant AP cluster shares which type of key to allow seamless client roaming without re-authentication?

    Answer: OKC (Opportunistic Key Caching) distributed across all IAPs

    Aruba Instant clusters distribute the PMK via Opportunistic Key Caching so clients can roam between cluster members without performing a full 802.1X re-authentication.

  7. Which Aruba feature dynamically assigns clients to different APs based on load, signal strength, and band conditions?

    Answer: ClientMatch

    ClientMatch continuously evaluates client RF conditions and steers clients to the optimal AP or band through targeted de-authentication and re-association guidance.
