  1. A Wi-Fi 6 (802.11ax) AP is installed in a warehouse, but clients only connect at 802.11n rates. What is the most likely reason?

    Answer: The client devices do not support 802.11ax

    Clients can only negotiate the highest rate mutually supported; if client NICs are 802.11n-only, they will connect at 802.11n rates regardless of AP capability.

  2. You observe that clients near AP boundaries are 'sticky' and do not roam to a closer AP. What feature can help resolve this?

    Answer: 802.11r fast BSS transition or BSS transition management (802.11v)

    BSS Transition Management (802.11v) allows the AP to suggest better APs to clients, encouraging roaming away from a distant AP.

  3. During preventive maintenance, a technician inspects AP mounting locations. Which condition requires immediate attention?

    Answer: The AP enclosure shows signs of water ingress or corrosion

    Water ingress or corrosion can cause hardware failure, electrical hazards, and void warranties, requiring immediate remediation.

  4. What is the effect of setting the minimum basic rate too low (e.g., 1 Mbps) on a busy WLAN?

    Answer: Legacy clients consume more airtime, reducing performance for all users

    Lower minimum basic rates allow legacy clients to stay connected at slow rates, consuming excessive airtime and degrading the entire cell's capacity.

  5. A technician uses a Wi-Fi analyzer and sees dozens of SSIDs on channel 6 in the 2.4 GHz band. The recommended action is:

    Answer: Move the APs to non-overlapping channels 1 or 11 to reduce co-channel interference

    Moving to channels 1 or 11 reduces co-channel interference when channel 6 is saturated with neighboring networks.

  6. After a power outage, several APs do not come back online. The most likely cause is:

    Answer: The PoE switch or injectors did not restore power to all ports

    PoE switches sometimes do not restore power to all ports after a power event due to budget limits or port priority settings.

  7. A client reports intermittent connectivity that correlates with microwave oven use in the break room. Which band and channel combination is most affected?

    Answer: 2.4 GHz, channel 6

    Microwave ovens emit RF energy around 2.45 GHz, which overlaps with the 2.4 GHz Wi-Fi band and particularly impacts channels near the center of the band such as channel 6.
