CWDP: Certified Wireless Design Professional v303 — Question 10

Your customer's 802.11n laptops are not able to see the SSID in the 5 GHz band in the conference room. When doing a walkthrough using one of these laptops, you confirm that it is unable to see the SSID in the 5 GHz band in the conference room. When using your own 802.11 ac laptop, you're able to see the SSID. What is the most likely cause of this problem?

Answer options

• A. The AP is configured to use channel 36
• B. The customer laptop does not support Transmit Beamforming
• C. The AP is on channel 144
• D. Their laptops are SISO clients

Correct answer: B

Explanation

The correct answer is B because 802.11n laptops may not support Transmit Beamforming, which can affect their ability to detect signals in the 5 GHz band. Options A and C are irrelevant since the channel configuration does not impact the compatibility of 802.11n with Beamforming. Option D is also incorrect as SISO clients can still connect, but may perform poorly without Beamforming support.
