Suggested Answer: C

Sensors should be deployed in critical areas where WLAN performance must be high for best results when using a WLAN monitoring solution that utilizes distributed sensor devices. A WLAN monitoring solution is a system that collects, analyzes, and reports on the status and performance of a WLAN. A WLAN monitoring solution can use different methods to gather data from the WLAN, such as embedded software agents, external hardware probes, or distributed sensor devices. Distributed sensor devices are dedicated devices that are deployed throughout the WLAN coverage area to monitor the wireless traffic and environment. Distributed sensor devices can perform various functions, such as scanning the spectrum, capturing wireless frames, measuring signal quality, detecting rogue access points, testing connectivity, and generating alerts. Distributed sensor devices can provide more accurate and comprehensive data than other methods, but they also require more planning and deployment costs. Therefore, it is important to deploy sensors strategically in critical areas where WLAN performance must be high, such as high-density zones, high-priority applications, or high-security locations. By deploying sensors in critical areas, the WLAN monitoring solution can ensure optimal WLAN performance and reliability in those areas and identify and resolve any issues or problems that may arise. The other options are not the best places to deploy sensors for best results. Deploying sensors in switching closets is not effective because sensors need to be close to the wireless medium to monitor it properly. Deploying sensors every 5 meters and alongside each AP is not efficient because sensors may overlap or interfere with each other and cause unnecessary redundancy or complexity.Deploying sensors above the plenum on each floor is not practical because sensors may not capture the wireless traffic and environment accurately due to attenuation or reflection from the ceiling materials or objects.Reference:CWNA-109 Study Guide, Chapter 14: Troubleshooting Wireless LANs, page 4831

This question is a breeze! C is the clear winner. You want to monitor where the performance really matters, not just blanket the whole area.

Hmm, I'm feeling a bit mischievous today. Maybe I'll go with A just to see the looks on the instructors' faces. Switching closets, really?

I think sensors above the plenum on each floor would provide the best results for WLAN monitoring.

I'm going with B. Spacing them out every 5 meters and alongside each AP is the only way to get a comprehensive view.

D, all the way! Putting those sensors above the plenum is a stroke of genius. Nothing gets past that.

C seems like the obvious choice. You don't need sensors everywhere, just the critical areas, am I right?
