  1. What is the purpose of a wireless intrusion detection system (WIDS) in network optimization?

    Answer: To monitor the RF environment for rogue APs, unauthorized clients, and attack patterns

    A WIDS continuously scans the RF environment to detect rogue devices, deauth attacks, and policy violations that can degrade performance and security.

  2. Which roaming standard defines over-the-air fast BSS transition to reduce handoff latency for VoIP clients?

    Answer: 802.11r

    802.11r (Fast BSS Transition) pre-establishes security keys with neighboring APs so roaming clients can associate in milliseconds without a full re-authentication.

  3. A wireless specialist wants to reduce broadcast and multicast traffic overhead on a high-density WLAN. What is the best approach?

    Answer: Enable multicast-to-unicast conversion on the AP or controller

    Converting multicast to unicast allows the AP to send individual unicast frames at each client's supported rate, reducing airtime waste from low-rate broadcast transmissions.

  4. What is the recommended maximum number of SSIDs per radio to minimize management frame overhead?

    Answer: 4

    Best practice recommends no more than 4 SSIDs per radio because each additional SSID adds beacon overhead and reduces available airtime for data.

  5. Which 802.11 amendment introduced neighbor report and BSS load information to assist clients in making better roaming decisions?

    Answer: 802.11k

    802.11k provides clients with neighbor AP reports and load information so they can make informed roaming decisions before disconnecting.

  6. When optimizing a WLAN for high-density environments, what is the recommended transmit power level setting for client devices?

    Answer: Low power (e.g., 5–10 dBm) to reduce co-channel interference and encourage nearby AP association

    Reducing client transmit power in high-density areas limits interference range and encourages devices to associate with the closest AP rather than a distant one.
