The answer is to enable SSID broadcast for the SecureCorp WLAN. The client cannot see the SSID because the broadcast function is disabled, which prevents the access point from including the network name in its beacon frames. Even though the security and VLAN mapping to interface corp_vlan are correctly configured, a hidden SSID requires the client to manually enter the exact name, causing the association failure. On the CCNA 200-301 v2 exam, this scenario tests your understanding that WLAN visibility is controlled independently from security settings, and it is a common trap to assume a correctly configured PSK or VLAN guarantees client discovery. Remember the memory tip: “No beacon, no beacon—broadcast must be on for the client to see the SSID.”
CCNA Network Infrastructure and Connectivity Practice Question
This 200-301 practice question tests your understanding of network infrastructure and connectivity. The scenario asks you to isolate a root cause — eliminate options that address a different problem before choosing. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
Network Topology
You are connected to the WLC via its management IP 192.168.10.10. A new corporate SSID 'SecureCorp' must be configured for WPA3-Personal with PSK 'Cisco123' on the 5 GHz radio only. The SSID should be broadcast. The WLAN must be mapped to interface 'corp_vlan' (VLAN 100). After configuration, a wireless client reports it cannot see or connect to the SSID. Troubleshoot and resolve the client's association failure.

A
Enable SSID broadcast for the SecureCorp WLAN.
The client cannot see the SSID because broadcast SSID is disabled. Enabling broadcast SSID allows the client to discover the network without manual entry, resolving the association failure.
B
Change the security mode to WPA2-Personal with the same PSK.
Why wrong: This is incorrect because the client's inability to see the SSID is due to the hidden SSID, not the security mode. Changing to WPA2-Personal does not address the visibility issue.
C
Reconfigure the WLAN to use interface 'management' instead of 'corp_vlan'.
Why wrong: This is incorrect because the interface mapping does not affect SSID visibility. The client cannot see the SSID due to the hidden broadcast setting, not the VLAN assignment.
D
Disable the 5 GHz radio and enable the 2.4 GHz radio for the SecureCorp WLAN.
Why wrong: This is incorrect because the client's inability to see the SSID is not related to the radio band. The SSID is hidden on the 5 GHz radio; switching bands does not solve the visibility problem.

Correct answer & explanation
✓
Enable SSID broadcast for the SecureCorp WLAN.
The client cannot see the SSID because SSID broadcast is disabled. The SSID is configured to be broadcast, but the actual setting is off. To resolve, enable SSID broadcast on the WLAN. The security and VLAN settings are correct. Enabling broadcast allows the client to discover the network without manual entry.
Key principle: A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.

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.
✓Enable SSID broadcast for the SecureCorp WLAN.Correct answer▾
Why this is correct
The client cannot see the SSID because broadcast SSID is disabled. Enabling broadcast SSID allows the client to discover the network without manual entry, resolving the association failure.
✗Change the security mode to WPA2-Personal with the same PSK.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that the security mode does not affect SSID visibility; the problem is the broadcast setting.
Why candidates choose this
Candidates pick this because they assume WPA3 compatibility issues cause the failure, but the client may support WPA3 and the real issue is the hidden SSID.
✗Reconfigure the WLAN to use interface 'management' instead of 'corp_vlan'.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that interface mapping controls VLAN assignment for traffic, not SSID broadcast.
Why candidates choose this
Candidates pick this because they think a misconfigured interface prevents client association, but the client cannot even see the SSID, indicating a broadcast issue.
✗Disable the 5 GHz radio and enable the 2.4 GHz radio for the SecureCorp WLAN.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that radio band selection does not affect SSID broadcast; the hidden SSID prevents discovery on any band.
Why candidates choose this
Candidates pick this because they think the client might not support 5 GHz, but the client reports it cannot see the SSID at all, indicating a broadcast issue rather than band incompatibility.

Common exam traps
Common exam trap: an active trunk can still block the VLAN you need
A trunk being up does not prove every VLAN is crossing it. Check allowed VLAN lists, native VLAN mismatch, VLAN existence and access-port assignment.
Detailed technical explanation
How to think about this question
VLAN questions usually combine access-port and trunking clues. The key is to identify whether the issue is local to one switchport, caused by the trunk, or caused by the VLAN not existing where it needs to exist.
KKey Concepts to Remember
Access ports place end devices into a single VLAN.
Trunk ports carry multiple VLANs between switches.
Allowed VLAN lists decide which VLANs can cross a trunk.
Native VLAN mismatch can create confusing symptoms.
TExam Day Tips
→Use show vlan brief to verify access VLANs.
→Use show interfaces trunk to verify trunk state and allowed VLANs.
→Do not treat every same-VLAN issue as a routing problem.
Key takeaway
A trunk being up does not mean the VLAN is allowed across it. Always verify the allowed VLAN list and whether the VLAN exists on both switches.
Real-world example
How this comes up in practice
A help-desk technician troubleshoots why a newly connected PC cannot reach shared printers on the same floor. The cable is good, the switch port is active, but the PC is in VLAN 20 and the printers are in VLAN 10. The uplink trunk only allows VLAN 10. A trunk being up does not mean every VLAN crosses it.
