Exam 350-401 topic 1 question 152 discussion

when a radio changes from one channel to another, the user gets disconnected shortly, so increase DCA to more than 10 mins( default DCA) to reduce the number of times users are disconnceted .

These message logs inform that the radio channel has been reset (and the AP must be down briefly). With dynamic channel assignment (DCA), the radios can frequently switch from one channel to another but it also makes disruption. The default DCA interval is 10 minutes, which is matched with the time of the message logs. By increasing the DCA interval, we can reduce the number of times our users are disconnected for changing radio channels.

I think it's A , enabling coverage hole detection should make dynamic channel assignment less frequent in the first place , because there would be less need to reassign the channel

The access points are frequently changing channels, which causes frequent disconnections for users. This issue can be fixed by increasing the interval for channel assignment, which is the time it takes for an AP to assign a new channel. This adjustment results in improved network stability.

D is correct

The RRMcoverage hole detection algorithm can detect areas of radio coverage in a wireless LAN that are below the level needed for robust radio performance. This feature can alert you to the need for an additional (or relocated) lightweight access point. Don't think this meets the criteria

A. Enable coverage hole detection. The symptoms described in the scenario, where wireless users experience frequent disconnections from the network but the connection re-establishes automatically without any input, can be indicative of coverage holes in the wireless network. Coverage holes are areas where the wireless signal strength is insufficient, leading to connectivity issues for users within those areas. By enabling coverage hole detection, the wireless network can identify and mitigate these coverage holes more effectively. Coverage hole detection allows the access points (APs) to monitor the signal strength and quality within their coverage areas. If a coverage hole is detected, the AP can take proactive measures to address the issue, such as adjusting transmit power, optimizing channel selection, or triggering alarms for further investigation. Enabling coverage hole detection helps in identifying and resolving areas with poor coverage, improving the overall user experience by reducing the frequency of disconnections.

Of the options provided, the most relevant action that can help with this issue is to enable coverage hole detection. Coverage hole detection allows access points to detect when client devices are unable to connect or stay connected to the wireless network due to a weak signal or other issues, and take appropriate action to mitigate the issue, such as increasing transmit power or changing channels. Therefore, the correct answer is A. enable coverage hole detection.
