Designing Cisco Wireless Enterprise Networks (WIDESIGN, legacy) — Question 15

After the completion of a site survey with Ekahau Site Survey tool, using the default color palette, it is noted that multiple areas are shown as white on the heat map when viewing 5 GHz signal strength data. What does this indicate about the signal strength?

Answer options

• A. The area is below the minimum threshold configured on the tool.
• B. The area is below the detectable level and indicates no RF signal.
• C. The area is below -100 dBm at coverage cell edge.
• D. The area is below -67 dBm at coverage cell edge.

Correct answer: B

Explanation

The correct answer is B because white areas on the heat map indicate that the signal strength is below the detectable level, meaning there is no RF signal present. Options A, C, and D refer to specific thresholds for signal strength that do not accurately describe the absence of a detectable signal, which is the condition represented by the white areas.
