A dual-band 802.11ac AP must be powered by PoE. As a class 4 device, what power level should be received at the AP?

Show Suggested Answer Hide Answer
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

12.95 W seems way too low for an AP!

I thought class 4 meant it should be 30 W, but I also remember something about 12.95 W for lower classes. This is tricky!

I feel like I might be mixing up the power levels. Was it 15.4 W for class 4? That seems low, but I can't recall clearly.

I remember practicing a question like this, and I think class 4 devices typically need about 25.5 W.

I think a class 4 device should receive around 30 W, but I'm not entirely sure if that's correct.

I've got this! A class 4 PoE device can receive up to 30W of power. So the correct answer is A, 30W.

Wait, I thought class 4 was 15.4W. Or was that class 3? I'm getting a bit mixed up on the PoE power classes. I'll have to review my notes before answering this.

Okay, let me see if I can work this out. A class 4 device means it can draw up to 30W, right? So the power level received at the AP should be 30W.

Hmm, I'm a bit unsure about this one. I know PoE has different power classes, but I can't quite recall the specifics off the top of my head. I'll have to think this through carefully.

Wait, is this a trick question? I mean, who reads the fine print on these PoE standards, am I right? *chuckles* But seriously, I think option D is the way to go.

Ah, this is a tricky one. I know PoE class 4 can deliver up to 30W, but the question is asking about the power level received at the AP, not the maximum available. Gotta be careful with these subtle details!

I'm not sure, but I think it might be D) 15.4 W because of the power requirements for a dual-band 802.11ac AP.

Okay, let's think this through. Class 4 PoE is supposed to provide up to 30W, but the AP might not actually receive the full 30W due to cable losses and other factors. I'm going to go with option B.
