Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 35

A network engineer notices that two mesh APs are having problems communicating. After reviewing the current radio configurations, it is noted that one AP is transmitting at 3 mW while the other is transmitting at 60 mW. How many decibels would the 3-mW AP need its power increased to match the 60-mW AP?

Answer options

• A. 8
• B. 12
• C. 13
• D. 20
• E. 57

Correct answer: C

Explanation

The power difference between 3 mW and 60 mW can be calculated using the formula 10 * log10(P2/P1). In this case, P2 is 60 mW and P1 is 3 mW, which results in an increase of approximately 13 dB. The other options do not accurately represent the dB increase needed to match the power levels.
