350-401 Question 178
Single answerYou are troubleshooting a wireless connectivity issue in a small office where multiple users are unable to connect to the corporate WLAN. Using the Cisco Wireless LAN Controller (WLC) GUI, you notice that the affected clients are associated with the SSID but are unable to obtain an IP address. What is the most likely root cause of the issue?
- A
The DHCP scope on the connected VLAN is exhausted.
- B
The SSID is incorrectly configured with WPA3-Enterprise security.
- C
The wireless clients are using unsupported Wi-Fi standards.
- D
The WLC has reached its maximum supported client limit.
Show answer and explanation
Correct answer: A
Explanation
The issue described indicates that the clients can associate with the SSID but fail to obtain an IP address. This strongly suggests a problem with the DHCP scope, such as it being exhausted, preventing the assignment of IP addresses to new clients. The other options do not align with the observed symptoms.
- A. Correct.
If the DHCP scope is exhausted, clients can associate with the SSID but fail to obtain an IP address, leading to connectivity issues.
- B. Incorrect.
While WPA3 incompatibility can cause connectivity issues, it would prevent clients from associating with the SSID altogether, which is not the case here.
- C. Incorrect.
If clients were using unsupported Wi-Fi standards, they would not be able to associate with the SSID at all, which is not what is observed here.
- D. Incorrect.
If the WLC had reached its maximum client limit, no new clients would be able to associate with the SSID. However, the problem here is with IP address assignment, not client association.
