Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 239

An AP is receiving 802.11 packets on its 802.11a radio with an RSSI value of -77 dBm. The current AP is part of an AP group that has been assigned an RF profile with RX-SOP set to Medium for 802.11a. Which action does the AP take with the packets?

Answer options

• A. All frames are classified as non-Wi-Fi frames and are not decoded by the 5 GHz radio.
• B. Frames are decoded by the 2.4 GHz radio.
• C. All frames are classified as non-Wi-Fi frames and are not decoded by the 2.4 GHz radio.
• D. Frames are decoded by the 5 GHz radio.

Correct answer: D

Explanation

The correct answer is D because the RSSI value of -77 dBm falls within the acceptable range for the 802.11a radio and the RX-SOP set to Medium allows the AP to decode the frames. Options A and C incorrectly state that the frames are classified as non-Wi-Fi, while option B incorrectly indicates that they are processed by the 2.4 GHz radio instead of the 5 GHz radio.
