Question #: 74
Topic #: 1

A network administrator redesigned the positioning of the APs to create adjacent areas of wireless coverage. After project validation, some users still report poor connectivity when their devices maintain an association to a distanced AP. Which of the following should the network administrator check FIRST?

A. Validate the roaming settings on the APs and WLAN clients
B. Verify that the AP antenna type is correct for the new layout
C. Check to see if MU-MIMO was properly activated on the APs
D. Deactivate the 2.4GHz band on the APS

Selected Answer: A

Roaming is the process of switching from one AP to another as the user moves around the network. If the roaming settings are not configured correctly, the user may experience poor connectivity when the device maintains an association with a distant AP. Improper roaming settings can result in slow speeds, dropped connections, and low signal strength. Therefore, validating the roaming settings is the first step the network administrator should take when addressing the issue of poor connectivity. The roaming settings need to be configured in a way that allows the device to seamlessly switch from one AP to another as the user moves around the network. If the roaming settings are not configured properly, the network administrator should adjust them to ensure the best possible user experience. By validating the roaming settings first, the network administrator can eliminate the possibility of this being the root cause of the issue, and move on to other potential causes if necessary.

This would be true if option A only specified AP roaming settings. However, it clearly says CLIENTS, making A incorrect as an answer. B is correct.

This is literally why A is the answer. "some users" stay connected to the far APs "when their devices maintain an association to a distanced AP" This is literally what roaming is for, and you can change the aggressiveness of it on the client, so you have to check whether roaming isn't set properly.

It's not the best question in my opinion. I would say the answer is A because if you read it carefully it states that 'some' users are having difficulties, not 'all' users. This to me suggest that (despite the redesign) some other users are fine and so it is more likely that there is an issue with their device than the antenna.

Selected Answer: B

Surely the answer has to be B. The questions specifically asks for the FIRST thing to check. While validating the roaming settings on the APs is easy and quick, I would say that checking the roaming settings on client devices would be the LAST thing to check. Therefore B must be the easiest, quickest, most efficient, and FIRST thing an admin would check.

"some users" stay connected to the far away APs, what does this have anything to do with antennas. Clearly it's a roaming issue.

Agree. Nothing else matters unless you verify antenna type first.

I just tried this on my router, you can decide which decible your going to be disconnected.

A. Because it could be due to the WLAN clients

I think B is the best answer because they have repositioned APs and the connections for some, not all, users are poor. Must be directional antennas pointing in the wrong or at least not best directions? Makes sense to me anyways

That's a good point, but if you think about the effort that you'd need to employ to determine if that would work? It would be a better first choice to verify you've connected the roaming settings, and if they are not correct, you can adjust those before moving on to more high effort troubleshooting options.

would not be B?

I would not say B because the scenario is say they re modeled, so seeing if the NEW antennas work does not apply

If correct antennas are not being used couldn’t that also create an issue of staying connected. If a directional antenna was being used by an adjacent ap, pointed in the direction of another ap with a Omni-directional antenna?
