CWNA: Certified Wireless Network Administrator v107 — Question 26

A client STA must choose the best AP for connectivity. As part of the evaluation, it must verify compatible data rates. What can the client STA use to verify that an
AP supports the same data rates that it supports?

Answer options

• A. Beacon frames transmitted by the AP
• B. Data frames sent between the AP and current clients STAs
• C. Authentication frames transmitted by the other client STAs
• D. Probe request frames transmitted by other client STAs

Correct answer: D

Explanation

The correct answer is D because probe request frames allow a client STA to discover available APs and their supported data rates. Options A and B do not provide the necessary information regarding the data rates supported, and option C is irrelevant as it pertains to authentication rather than data rates.
