Discuss CWNP CWNA-109 Exam Topic 6 Question 42

A client STA must choose the best AP for connectivity. As part of the evaluation, it must verify compatible data rates. What can the client STA use to verify that an

AP supports the same data rates that it supports?

ABeacon frames transmitted by the AP

BData frames sent between the AP and current clients STAs

CAuthentication frames transmitted by the other client STAs

DProbe request frames transmitted by other client STAs

Suggested Answer: A

The client STA can useBeacon frames transmitted by the APto verify that an AP supports the same data rates that it supports. Beacon frames are management frames that are periodically broadcasted by the APs to announce their presence, capabilities, and parameters. One of the information elements contained in the Beacon frames is the Supported Rates or Extended Supported Rates, which lists the data rates that the AP can use for communication. The client STA can compare its own data rates with those advertised by the AP to determine if they are compatible. Data frames, authentication frames, and probe request frames do not contain information about data rates.Reference:[CWNP Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 133; [CWNA: Certified Wireless Network Administrator Official Study Guide: Exam CWNA-109], page 123.

Yeah, A is the way to go. Good reasoning!

I feel confident about A too. It’s the standard method.

Johana 1 month ago

Right, A is straightforward. Clear info from the AP.

Meaghan 1 month ago

C and D don’t help with data rates. They’re not relevant.

Keshia 1 month ago

But B depends on current clients. A is more reliable.

Nickole 2 months ago

I’m leaning towards B. Data frames show real-time rates.

Jaime 2 months ago

Agreed, A makes sense. It broadcasts capabilities.

Louvenia 2 months ago

I think A is the best choice. Beacon frames show supported rates.

Vincenza 2 months ago

Nah, it's definitely the beacons. They broadcast the capabilities!

Jesusita 2 months ago

I thought probe requests were more relevant for this?

Leota 2 months ago

Wait, are we sure about that? What about data frames?

Chanel 3 months ago

Totally agree, those beacons carry the data rates info.

Kallie 3 months ago

A) Beacon frames transmitted by the AP is the right choice!

Lashandra 3 months ago

I’m leaning towards A) as well, but I wonder if there’s a chance that B) could provide some insight too, since it involves current connections.

Pearline 3 months ago

I feel like we discussed probe requests in class, but I can't recall if they actually help with verifying data rates. Could it be D)?

Susy 3 months ago

I'm not entirely sure, but I remember something about data frames being used for communication, so maybe B) is relevant too?

Nicholle 4 months ago

I think the answer might be A) Beacon frames, since they contain information about the supported data rates of the AP.
