Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 862

What is the wireless Received Signal Strength Indicator?

Answer options

• A. the value given to the strength of the wireless signal received compared to the noise level
• B. the value of how strong the wireless signal is leaving the antenna using transmit power, cable loss, and antenna gain
• C. the value of how much wireless signal is lost over a defined amount of distance
• D. the value of how strong a wireless signal is received, measured in dBm

Correct answer: D

Explanation

The correct answer is D, as the Received Signal Strength Indicator (RSSI) specifically indicates the strength of a received wireless signal in dBm. Option A discusses signal strength relative to noise but does not define RSSI. Option B refers to transmit power and antenna characteristics, which are not related to the received signal. Option C focuses on signal loss over distance, which is not the same as the measurement of the received signal strength.
