300-425 Question 127
Single answerAn enterprise network administrator is troubleshooting a wireless client device that periodically disconnects from the corporate Wi-Fi network. Upon investigation, the administrator observes that the client frequently switches between two access points (APs) despite having a strong signal from one AP. What is the most likely reason for this behavior?
- A
The client is configured with an aggressive roaming threshold.
- B
The access points are using different SSIDs.
- C
The wireless network is operating on a legacy 802.11b standard.
- D
The client device is experiencing hardware issues.
Show answer and explanation
Correct answer: A
Explanation
The client device's aggressive roaming threshold setting is likely causing it to switch access points more frequently than necessary, even when the current AP's signal is sufficient. Adjusting the roaming sensitivity on the client device can help resolve this issue. Understanding client behavior and configuration is critical in troubleshooting enterprise wireless networks.
- A. Correct.
If the client is configured with an aggressive roaming threshold, it will attempt to switch access points more frequently, even when the signal from the current AP is still strong. This is a likely reason behind the issue.
- B. Incorrect.
If the access points used different SSIDs, the client would not switch between them unless explicitly configured to do so. This would result in a failure to connect rather than periodic disconnections.
- C. Incorrect.
If the network were using a legacy standard like 802.11b, it would cause performance and speed issues, but it would not directly lead to frequent roaming or disconnections.
- D. Incorrect.
Hardware issues could cause connectivity problems, but they are less likely to result in the observed behavior of frequent switching between APs.
