CWNP Exam CWAP-404 Topic 3 Question 32 Discussion

Actual exam question for CWNP's CWAP-404 exam

Question #: 32
Topic #: 3

You're the WLAN administrator for a large retailer based at the HQ in New York. The London-based office has been complaining about WLAN disconnections around lunch time each day. You suspect this might be interference from the staff microwave, how might you test your theory from the New York office?

AAsk a local member of staff to change the frequency of the microwave and see if the disconnections stop

BAsk a local member of staff to take some pictures of the microwave, including some close-ups of the door seal so that you can assess it

CAccess the microwave remotely and run a diagnostic check

DPlace one of the London APs into spectrum analyzer mode and monitor the situation over lunch time

Show Suggested Answer

Suggested Answer: D

The best way to test the theory of microwave interference from the New York office is to use a remote spectrum analyzer. By placing one of the London APs into spectrum analyzer mode, you can capture and analyze the RF spectrum in the London office over lunch time. You can then look for any signs of microwave interference, such as high duty cycle, high amplitude, or frequency hopping on the 2.4 GHz band. This method does not require any physical access to the microwave or any changes to its frequency.Reference:[Wireless Analysis Professional Study Guide], Chapter 3: Spectrum Analysis, page 64

I'm just picturing the WLAN admin in New York trying to remotely access the microwave. That's the kind of tech support nightmare that keeps me up at night.

B) I don't think changing the frequency of the microwave will help, it's more about the interference it causes

Option A? Really? Asking someone to change the microwave frequency? That's about as useful as trying to nuke the problem from orbit.

I think we should try both options D and C to cover all bases and find the root cause of the disconnections.

I'm not sure about option D, maybe we should also consider option C and run a diagnostic check on the microwave remotely.

B seems like a waste of time. I mean, how are some photos of the microwave going to help you figure this out?

Ah, the classic microwave interference problem. I'd go with D - get that AP in spectrum mode and let's see what's cooking!

I think C is the way to go. Being able to remotely access and diagnose the microwave would be the most efficient solution.

Option D for sure! You need to get that spectrum analyzer going to see what's really going on in the London office.

We can't just rely on changing the frequency of the microwave without knowing for sure if that's the issue.

I agree with Ashlee, that seems like the most direct way to test the interference theory.
