You are troubleshooting a wireless client connectivity issue on the Cisco WLC at 192.168.1.100. The client reports it can see the SSID 'CorpNet' and successfully associates, but cannot obtain an IP address or reach network resources. The WLAN is already configured with WPA3 security, and the SSID should remain hidden. Identify and correct the configuration issue.
⚠ Common exam trap
Clients seeing the SSID indicates the WLAN is enabled and broadcasting; association can complete even on the wrong interface. The actual symptom is a lack of IP connectivity, not an association failure. Always check the WLAN-to-interface mapping when clients associate but cannot reach network services.
Answer choices
Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
The WLAN is mapped to the management interface. Use 'config wlan interface 1 CorpNet_VLAN' to assign the correct interface.
The WLAN is incorrectly mapped to the management interface, which places client traffic in the management VLAN instead of the correct CorpNet_VLAN. As a result, clients cannot obtain IP addresses or communicate beyond the WLC. Reassigning the WLAN to the CorpNet_VLAN interface with 'config wlan interface 1 CorpNet_VLAN' resolves the issue by placing client data in the proper VLAN.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✓
The WLAN is mapped to the management interface. Use 'config wlan interface 1 CorpNet_VLAN' to assign the correct interface.
Why this is correct
The WLAN's interface mapping determines which switch VLAN will carry wireless client traffic. Mapping it to the management interface places clients into the management network, where no DHCP server exists for end users, so the client can associate at Layer 2 but never completes IP configuration. Reassigning the WLAN to CorpNet_VLAN directs client traffic onto the appropriate data VLAN, allowing the client to receive a valid address and communicate. This directly resolves the association/connectivity issue described.
- ✗
The SSID is not hidden. Use 'config wlan disable-broadcast-ssid 1 enable' to hide the SSID.
Why it's wrong here
The client's ability to see the SSID indicates that beaconing and probe responses are functioning, so the SSID is not hidden. Hiding the SSID would merely stop the name from being broadcast in beacons; it does not affect association at Layer 2. The reported failure occurs after the client discovers the network, so this change would not resolve the actual cause—the WLAN's interface binding.
- ✗
WPA3 is not enabled on the WLAN. Use 'config wlan security wpa akm 6 enable' to enable WPA3.
Why it's wrong here
This is incorrect because the question states the client can see the SSID but fails to associate. If WPA3 were not enabled, the client would likely not see the SSID or would fail at authentication, not association. The association failure is due to interface mapping.
- ✗
The WLAN is disabled. Use 'config wlan enable 1' to enable the WLAN.
Why it's wrong here
If the WLAN were disabled, the access point would not transmit beacons or respond to probe requests, and the client would not see the SSID in its scan results. Since the client does see the SSID, the WLAN is actively enabled. Enabling it would change nothing because the problem is not WLAN availability but the interface to which the WLAN is mapped; the client associates but cannot obtain an IP on the management network.
Option-by-option analysis
Why each answer is right or wrong
Understanding why wrong answers are wrong — and when they would be correct — is what separates a 750 score from a 900. The 200-301 exam frequently reuses these exact scenarios with slightly different constraints.
✓The WLAN is mapped to the management interface. Use 'config wlan interface 1 CorpNet_VLAN' to assign the correct interface.Correct answer▾
Why this is correct
The WLAN's interface mapping determines which switch VLAN will carry wireless client traffic. Mapping it to the management interface places clients into the management network, where no DHCP server exists for end users, so the client can associate at Layer 2 but never completes IP configuration. Reassigning the WLAN to CorpNet_VLAN directs client traffic onto the appropriate data VLAN, allowing the client to receive a valid address and communicate. This directly resolves the association/connectivity issue described.
✗The SSID is not hidden. Use 'config wlan disable-broadcast-ssid 1 enable' to hide the SSID.Wrong answer — click to see why▾
Why this is wrong here
The SSID is already hidden; enabling broadcast would make it visible, which violates the requirement.
Why candidates choose this
Candidates might pick this because they focus on the requirement to keep the SSID hidden and assume it is currently broadcast, but the client's ability to see the SSID does not mean it is broadcast; hidden SSIDs can still be seen by clients that know the SSID.
✗WPA3 is not enabled on the WLAN. Use 'config wlan security wpa akm 6 enable' to enable WPA3.Wrong answer — click to see why▾
Why this is wrong here
WPA3 is already configured; the client associates successfully, so no security change is needed.
Why candidates choose this
Candidates might pick this because the question mentions WPA3 clients, leading them to think the issue is with WPA3 configuration, but the association failure occurs at a lower layer.
✗The WLAN is disabled. Use 'config wlan enable 1' to enable the WLAN.Wrong answer — click to see why▾
Why this is wrong here
The client can see the SSID and associates, proving the WLAN is already enabled.
Why candidates choose this
Candidates might pick this because they assume a common issue is a disabled WLAN, but the symptom of seeing the SSID rules that out.
