  1. Which protocol does a CAPWAP-based access point use to communicate with a Wireless LAN Controller?

    Answer: UDP ports 5246 (control) and 5247 (data)

    CAPWAP uses UDP port 5246 for the control channel and UDP port 5247 for the data channel between AP and WLC.

  2. What is the purpose of 802.11k in a wireless network?

    Answer: Provide neighbor reports to help clients make better roaming decisions

    802.11k (Radio Resource Management) enables APs to provide clients with neighbor AP reports, improving roaming decisions and efficiency.

  3. An AP is drawing power from an 802.3af PoE switch port but fails to power on. What is the most likely cause?

    Answer: The AP requires 802.3at (PoE+) power and exceeds the 802.3af 15.4W budget

    802.3af provides up to 15.4W, while higher-end APs require 802.3at (PoE+) which provides up to 30W; a mismatch prevents the AP from booting.

  4. Which Wi-Fi Alliance certification program replaced WPA2 and introduced SAE (Simultaneous Authentication of Equals)?

    Answer: WPA3

    WPA3 replaced WPA2 and introduced SAE, which provides stronger password-based authentication and forward secrecy.

  5. A wireless network is experiencing slow performance because many legacy 802.11b clients are connected. What feature can the administrator enable to improve performance for newer clients?

    Answer: Enable minimum basic rate and disable lower data rates like 1 and 2 Mbps

    Disabling low legacy data rates (1, 2, 5.5 Mbps) forces slower clients off the network or to connect less frequently, reducing airtime overhead.

  6. What is the primary function of BSS Coloring introduced in 802.11ax?

    Answer: Reduce unnecessary channel contention by identifying overlapping BSS transmissions

    BSS Coloring marks frames with a color identifier so devices can distinguish between transmissions from their own BSS and neighboring BSSs, reducing unnecessary backoff.

  7. During AP installation, a technician uses a spectrum analyzer and sees a strong, consistent signal across the 2.4 GHz band. What is the most likely source?

    Answer: A microwave oven in operation

    Microwave ovens emit broadband interference across much of the 2.4 GHz band when in operation, affecting all 2.4 GHz channels.
