CWAP: Certified Wireless Analysis Professional v402 — Question 5

When using a commercial WLAN protocol analyzer, you notice that it is listing vendor names for some APs and client STAs.
What is the source of this information?

Answer options

• A. Broadcast name resolution
• B. Banner grabbing
• C. DNS name resolution
• D. Vendor OUI values

Correct answer: D

Explanation

The correct answer is D, Vendor OUI values, because these values are part of the MAC address and are assigned to manufacturers, allowing the analyzer to identify the vendor. The other options, such as A, B, and C, do not relate to identifying vendors based on MAC addresses.
