Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 182

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

Correct answer: C

Explanation

The correct answer is C because white areas on the heat map typically indicate that the signal strength has dropped below the minimum threshold set in the Ekahau tool. Options A and B specify specific dBm levels, which do not universally apply to all configurations, while D suggests no RF signal is detectable, which is not necessarily the case if the signal is simply below the minimum threshold.
