  1. A wireless client shows strong signal strength but experiences frequent disconnections. What should you check first?

    Answer: Check for RF interference sources near the client

    Frequent disconnections with strong signal often indicate RF interference rather than signal strength issues.

  2. During maintenance, you discover an AP's firmware is two major versions behind. What is the recommended action?

    Answer: Review release notes, test in a lab environment, then upgrade during a maintenance window

    Best practice is to review release notes for breaking changes, validate in a lab, and schedule upgrades during low-traffic windows.

  3. A site survey report shows a persistent -85 dBm noise floor in the 5 GHz band in one area. What does this indicate?

    Answer: A significant source of co-channel or adjacent-channel interference

    A noise floor of -85 dBm in 5 GHz is elevated and suggests a significant interference source degrading SNR.

  4. Users report slow Wi-Fi speeds only during business hours. Which troubleshooting step is most appropriate?

    Answer: Analyze channel utilization and client count during peak hours

    Time-correlated slowdowns point to capacity issues, so analyzing channel utilization and concurrent client load during peak hours is the right first step.

  5. After replacing a failed AP, roaming clients do not reconnect to the new AP. The most likely cause is:

    Answer: The replacement AP is using a different SSID profile

    If the SSID profile or WLAN configuration on the replacement AP does not match the rest of the network, clients will not associate.

  6. What does a CRC error counter incrementing rapidly on a wireless interface typically indicate?

    Answer: RF signal corruption or interference causing frame errors

    Rapidly incrementing CRC errors indicate that frames are being received corrupted, usually due to RF interference or poor signal quality.

  7. A technician needs to verify that a newly installed AP is transmitting at the correct power level. Which tool is most appropriate?

    Answer: Spectrum analyzer

    A spectrum analyzer can measure the actual RF transmit power and channel occupancy of an AP in real time.
