350-401 Question 179
Single answerA network administrator is troubleshooting a wireless client connectivity issue using the Cisco Wireless LAN Controller (WLC) web GUI. The client is unable to connect to the WLAN. Upon reviewing the settings in the GUI, the administrator notices the following:
- The SSID is configured correctly.
- The security policy is set to WPA2-PSK.
- The client device is listed as 'Excluded Clients' under the 'Monitor' tab.
What immediate action should the administrator take to resolve the connectivity issue?
- A
Remove the client from the 'Excluded Clients' list under the 'Monitor' tab.
- B
Change the security policy from WPA2-PSK to WPA3-Enterprise.
- C
Reconfigure the SSID to use Open Authentication.
- D
Restart the Wireless LAN Controller to clear any client state issues.
Show answer and explanation
Correct answer: A
Explanation
The 'Excluded Clients' list is used to block specific devices from connecting to the wireless network, either manually or due to policy violations (e.g., excessive authentication failures). In this scenario, the client's inability to connect is directly caused by being on the exclusion list. Removing the client from this list will resolve the issue without additional reconfiguration or disruptions.
- A. Correct.
Removing the client from the 'Excluded Clients' list will allow the device to reconnect, as excluded clients are blocked from associating with the WLAN.
- B. Incorrect.
Changing the security policy to WPA3-Enterprise would require reconfiguring both the wireless network and the client device, which is unnecessary and unrelated to the issue described.
- C. Incorrect.
Reconfiguring the SSID to use Open Authentication would reduce network security and is not relevant to resolving the issue.
- D. Incorrect.
Restarting the Wireless LAN Controller may temporarily clear the client exclusion, but it is not the recommended or efficient way to address this issue.
