Discuss CWNP CWNA-109 Exam Topic 5 Question 22

In addition to coverage analysis results, what should be included in a post-deployment site survey report to ensure WLAN users experience acceptable performance?

AWAN interface analysis results

BCapacity analysis results

CApplication Layer protocol availability analysis results

DLayer 4 protocol availability analysis results

Suggested Answer: A

OFDMA is a new modulation scheme introduced in 802.11ax that allows multiple users to share the same channel by dividing it into smaller subchannels called resource units (RUs). This improves the efficiency and capacity of the WLAN by reducing contention and overhead. However, to use OFDMA, both the AP and the client must support 802.11ax and negotiate the parameters of the subchannel allocation.Therefore, the customer needs to upgrade the clients that require OFDMA to 802.11ax devices12.

The other options are not correct because they do not reflect the reality of OFDMA.Option B is incorrect because OFDMA is a mandatory feature of 802.11ax for both downlink and uplink transmissions, and all 802.11ax APs must support it1. Option C is incorrect because OFDM and OFDMA are different modulation schemes, and OFDM does not allow multiple users to share the same channel.Option D is incorrect because 802.11ac devices cannot support OFDMA through driver upgrades, as they lack the hardware and firmware capabilities to do so2.

Capacity analysis is a must for good performance!

Bernardine 11 months ago

I disagree, Layer 4 protocol results aren't that important.

Shaunna 11 months ago

Surprised WAN interface analysis isn't mentioned more often!

Myong 11 months ago

I think application layer protocol availability is crucial too.

Destiny 11 months ago

Definitely need capacity analysis results!

Nu 12 months ago

I feel like WAN interface analysis results might not be as critical for a post-deployment survey. It’s more about the local network performance, right?

Vernice 12 months ago

I practiced a question similar to this, and I think capacity analysis results are definitely needed to assess user experience after deployment.

Tamar 12 months ago

I'm a bit unsure, but I think application layer protocol availability might be relevant too. It could affect how well applications run over the WLAN.

Lawrence 1 year ago

I remember we discussed the importance of capacity analysis in ensuring users have enough bandwidth. That seems crucial for performance.

Arthur 1 year ago

Based on my understanding, the post-deployment report should include an analysis of the application layer protocols and their availability to ensure users can access the services they need.

Micah 1 year ago

I'm a bit confused on this one. Is the question asking about WAN or WLAN performance? I want to make sure I understand the focus before answering.

Sherrell 1 year ago

Okay, I think I know the answer here. The post-deployment site survey should include capacity analysis results to ensure the WLAN can handle the expected user load.

Bea 1 year ago

Hmm, this seems like a tricky one. I'll need to think carefully about the key factors that contribute to WLAN user experience beyond just coverage.

Jina 1 year ago

Capacity analysis is the only way to ensure those WLAN users can surf the web at lightning speed. Gotta make sure there's enough bandwidth for all those selfies and memes.

Layer 4 protocol availability? I'm pretty sure that's just TCP and UDP, and we don't need to worry about that in a post-deployment survey. Capacity analysis is the way to go, hands down.

Application Layer protocol availability? I thought this was a WLAN survey, not a deep dive into the OSI model. Gotta stick to the basics, my friend.

Haha, did they really think WAN interface analysis was the answer? Clearly, they want us to look at the capacity of the network, not the guy on the other end of the line.

Wow, this question really tests our understanding of WLAN performance! Capacity analysis results are definitely the way to go, gotta make sure those users have enough bandwidth to stream their cat videos.
