CWAP: Certified Wireless Analysis Professional v402 — Question 3

You have implemented an AP at a remote office. It is a single-band AP supporting 802.11ac. Several users complain that their laptops cannot connect to the
WLAN. These laptops are from multiple vendors and range in age from 2 to 4 years. The SSID and security profile settings are correct. All default settings were used on the AP with the exception of the SSID and security settings.
What is the most likely issue preventing these STAs from connecting to the AP?

Answer options

• A. They do not support VHI and only support OFDM
• B. They are 5 GHz-only devices
• C. They are 2.4 GHz-only devices
• D. They do not support the basic data rates

Correct answer: C

Explanation

The correct answer is C, as the single-band AP supporting 802.11ac operates on the 5 GHz band, and if the laptops are 2.4 GHz-only devices, they will be unable to connect. Options A and D are incorrect because the laptops should still connect if they support basic data rates, and option B is incorrect since the devices cannot connect if they are strictly limited to 2.4 GHz.
