CWNP CWNA-109 Exam - Topic 4 Question 8 Discussion

Actual exam question for CWNP's CWNA-109 exam

Question #: 8
Topic #: 4

You are installing an AP to be used by 27 laptops. All laptops will connect on the 5 GHz frequency band. A neighbor network uses channels 1 and 6. What channel should be used for this AP and why?

AChannel 6, because it is always best to use this channel

BA 5 GHz channel, because channels 1 and 6 are 2.4 GHz channels they have no impact on the decision

CChannel 1, because it is best to use the channel with the lowest frequency

DChannel 11, because channels 1 and 6 are in use nearby

Show Suggested Answer

Suggested Answer: B

A 5 GHz channel should be used for this AP because channels 1 and 6 are 2.4 GHz channels and they have no impact on the decision. The 5 GHz frequency band offers more non-overlapping channels than the 2.4 GHz frequency band, which reduces interference and improves performance. The 5 GHz frequency band also supports higher data rates and wider channel bandwidths than the 2.4 GHz frequency band, which increases capacity and throughput. The 5 GHz frequency band also has less interference from other devices and sources than the 2.4 GHz frequency band, which enhances reliability and quality of service. Therefore, it is recommended to use the 5 GHz frequency band for WLANs whenever possible. Channels 1 and 6 are two of the three non-overlapping channels in the 2.4 GHz frequency band (the other one is channel 11). They are used by a neighbor network in this scenario, but they do not affect the channel selection for this AP because they operate in a different frequency band than the 5 GHz frequency band. Channel 6 is not always best to use; it depends on the interference and congestion level in the environment. Channel 1 is not best to use because it has a lower frequency than channel 6; frequency does not determine channel quality or performance. Channel 11 is not best to use because it is also a 2.4 GHz channel and it may interfere with channels 1 and 6.Reference:CWNA-109 Study Guide, Chapter 4: Antenna Systems and Radio Frequency (RF) Components, page 113

5 GHz channels are definitely the way to go!

I’m a bit confused; I thought we had to pick a channel that’s not in use, but I’m not sure if Channel 6 is really a bad idea since it’s already being used.

I feel like I saw a practice question where we had to choose a channel based on nearby networks. Could it be Channel 11?

I think the 5 GHz band is less crowded, so maybe we should pick a channel that isn't affected by the 2.4 GHz channels.

Channel 6 is always a safe bet, right? I mean, it's a common channel, so it should work well for this setup. I'm not sure if the neighbor network really matters in this case.

I think the key here is to use a channel that doesn't overlap with the neighbor's network. Since they're using channels 1 and 6, I'd go with channel 11 in the 5 GHz band to keep a safe distance.

Hmm, I'm a bit confused. Does the fact that the neighbor network is using 2.4 GHz channels really matter if we're using 5 GHz? I'm not sure if that's the right approach.

This seems pretty straightforward. Since the neighbor network is using 2.4 GHz channels 1 and 6, we should use a 5 GHz channel to avoid interference.

I'm a bit confused by the terminology here. I'm not sure I fully understand the difference between I/O bursting, throttling, threshold, and saturation. I'll need to review those concepts before answering.

I'm going with C. Lower frequency channels are always better, right? It's like trying to tune in to the AM radio station - the lower the frequency, the clearer the signal!

D is the correct answer. Channel 11 is the best choice to avoid interference with the nearby network on channels 1 and 6. It's like finding the last available seat at a crowded movie theater - you gotta grab it before someone else does!

I think the answer is B. Using a 5 GHz channel is the way to go since the neighbor network is on 2.4 GHz. It's like trying to have a conversation in a room with two other people - you just need to find your own quiet corner!
