Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 1001

If the maximum power level assignment for global TPC 802.11a/n/ac is configured to 10 dBm. which power level effectively doubles the transmit power?

Answer options

• A. 13 dBm
• B. 14 dBm
• C. 17 dBm
• D. 20 dBm

Correct answer: A

Explanation

The correct answer is A, 13 dBm, because a 3 dB increase in power effectively doubles the transmit power. The other options do not represent a 3 dB increase from 10 dBm, as 14 dBm is a 4 dB increase, while 17 dBm and 20 dBm are even higher increases.
