Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 112

An engineer is performing an active survey of a network that must support different types of mobile devices. The devices must be able to run an application that requires a minimum RF of 73 dBm. Which mobile device must be used for the survey?

Answer options

• A. one that has a receiver sensitivity of -70 dBm
• B. one that has the lowest receiver sensitivity
• C. one that has the most updated wireless card
• D. one that has 802.11a wireless support

Correct answer: B

Explanation

The correct answer is B because a device with the lowest receiver sensitivity would be able to detect weaker signals, making it better suited for an active survey in a variable environment. Options A and C do not guarantee adequate performance for the application since they do not meet the sensitivity requirement, while D, while it specifies a wireless standard, does not address receiver sensitivity directly.
