300-360 Question #33: Real Exam Question with Answer & Explanation

The correct answer is C: continuous -67 dBm coverage from one access point. Per Cisco's wireless LAN design guidelines, a voice deployment requires continuous -67 dBm coverage from at least one access point throughout the coverage area. This is the minimum signal threshold needed for reliable VoIP call quality on Cisco wireless phones. A medical treatmen

Question

An engineer is performing a predictive wireless design for a medical treatment environment, which requires data and voice services. Which of the following is a requirement for the design?

Options

Aoverlapping -72 dBm coverage from two access points
Boverlapping -67 dBm coverage from two access points
Ccontinuous -67 dBm coverage from one access point
Dcontinuous -72 dBm coverage from one access point

Explanation

Per Cisco's wireless LAN design guidelines, a voice deployment requires continuous -67 dBm coverage from at least one access point throughout the coverage area. This is the minimum signal threshold needed for reliable VoIP call quality on Cisco wireless phones. A medical treatment environment adds criticality (patient safety, no dropped calls) but does not change the baseline RF requirement - it still maps to the standard voice design threshold of -67 dBm continuous from one AP. The -72 dBm threshold applies to data-only designs. Overlapping from two APs (-67 dBm) is the requirement specifically for Cisco 7925 phones, but the general voice/data medical environment answer is continuous -67 dBm from one AP.
