  1. A school district reports that student Chromebooks frequently roam poorly between classrooms. APs are 802.11ac with 5 GHz only. What is the first thing to verify?

    Answer: That all APs share the same SSID, VLAN, and security configuration to form a unified ESS

    For seamless roaming, all APs must broadcast the same SSID with identical security settings on the same VLAN so clients can move between APs without re-authenticating.

  2. A CWS is asked to explain why a newly installed AP in a server room is not performing as expected. The spectrum analyzer shows a high noise floor at -85 dBm. What is the most likely cause?

    Answer: Fluorescent lighting, UPS units, or other electronic equipment in the server room are radiating RF noise

    Server rooms contain numerous electronic devices including UPS units and switching power supplies that can elevate the RF noise floor.

  3. An enterprise wants to deploy 802.11ax (Wi-Fi 6) to improve throughput in a dense office with 200+ clients. What key 802.11ax feature specifically addresses simultaneous uplink transmissions from multiple clients?

    Answer: UL MU-MIMO and OFDMA

    Wi-Fi 6 introduces uplink MU-MIMO and OFDMA, enabling the AP to receive simultaneous transmissions from multiple clients, dramatically improving dense-environment efficiency.

  4. A CWS discovers clients on channel 6 are experiencing interference from a neighboring business also on channel 6. The only available non-overlapping 2.4 GHz channels are 1 and 11. What is the correct action?

    Answer: Move affected APs to channel 1 or 11 to eliminate co-channel interference

    Channels 1, 6, and 11 are the only three non-overlapping channels in 2.4 GHz; moving to channel 1 or 11 eliminates co-channel interference from the neighbor on channel 6.

  5. A wireless controller alert shows an AP is operating in monitor mode instead of serving clients. What is the likely explanation?

    Answer: The AP has been designated as a wireless IDS/IPS sensor scanning for rogue devices and threats

    In managed WLAN deployments, some APs are placed in dedicated monitor mode to perform air monitoring, rogue AP detection, and intrusion prevention functions.

  6. A user's laptop shows full Wi-Fi bars but a ping test shows 40% packet loss. A spectrum scan reveals a clean RF environment. What should the technician investigate next?

    Answer: The AP's current client association count and whether it has reached its client limit

    When RF looks clean but performance is poor, an overloaded AP at or near its maximum associated client count can cause queuing delays and packet drops.

  7. A CWS is designing a WLAN for a multi-tenant office building where tenants must be completely isolated from each other. Which combination of features achieves this?

    Answer: Separate SSIDs per tenant with client isolation and dedicated VLANs routed to separate firewall zones

    Per-tenant SSIDs with client isolation, VLAN segmentation, and separate firewall zones ensure complete Layer 2 and Layer 3 isolation between tenants.
