Designing Cisco Enterprise Wireless Networks (ENWLSD) — Question 4

As part of a wireless site survey in a hospital, an engineer needs to identify potential Layer 1 interferers. In which two areas is the engineer most likely to find sources of 2.4 GHz and 5 GHz RF noise? (Choose two.)

Answer options

• A. magnetic resonance imaging
• B. kitchen
• C. Gamma Knife radiation treatment
• D. X-ray radiography
• E. patient room

Correct answer: B, E

Explanation

The kitchen is a common source of RF noise due to appliances like microwaves, while patient rooms may contain various medical equipment that emits RF signals. Other options like magnetic resonance imaging and Gamma Knife treatments primarily deal with different types of radiation and are less likely to produce RF noise in the specified frequency bands.
