Implementing Cisco Wireless Network Fundamentals (WIFUND, legacy) — Question 101

What is the numerical value in dBm that corresponds to a power level of 50 mW?

Answer options

• A. 16
• B. 17
• C. 18
• D. 20

Correct answer: B

Explanation

The correct answer is 17 dBm because the formula to convert mW to dBm is 10 * log10(mW). For 50 mW, this calculation results in 17 dBm. The other options do not accurately reflect this conversion based on logarithmic calculations.
