The answer is to enable SSID broadcast, change the security to WPA3-Personal, and assign VLAN 100 in the policy tag. This is correct because the client’s association failures stem from three mismatches: the hidden SSID prevents the client from seeing the network, the WPA2 security does not support the client’s WPA3-Personal capability, and the policy tag’s VLAN 20 places the client on the wrong subnet. On the CCNA 200-301 v2 exam, this scenario tests your ability to configure WLAN parameters on a Cisco 9800 WLC, specifically the interplay between SSID visibility, security profiles, and policy tags—a common trap is forgetting that changing security requires removing the old WPA2 profile first. To fix it, use `broadcast-ssid` to make the SSID visible, then apply `security wpa wpa3` and `security wpa psk set-ccmp` to switch to WPA3-Personal, and finally set `vlan 100` under the policy tag. A helpful memory tip is “Broadcast, Upgrade, Re-VLAN”—three steps to fix a silent, insecure, misrouted client.
CCNA Network Infrastructure and Connectivity Practice Question
This 200-301 practice question tests your understanding of network infrastructure and connectivity. This is a configuration task: choose the command set that satisfies every stated requirement. Small differences — like 'secret' vs 'password' or 'transport input ssh' vs 'all' — change whether the answer is correct. 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 a Cisco 9800 WLC (WLC1) via its management interface. A wireless client reports association failures with SSID 'CorpNet'. The client uses WPA3-Personal, but the WLAN is configured for WPA2. Additionally, the SSID is hidden and the client is on the wrong VLAN (VLAN 20 instead of VLAN 100). Fix these issues so the client can associate successfully with WPA3, on VLAN 100, and with the SSID broadcast enabled.

A
Enable SSID broadcast, change security to WPA3-Personal, and assign VLAN 100 in the policy tag.
This option correctly addresses all three issues: enabling broadcast-ssid, configuring WPA3-Personal (by removing WPA2 and enabling WPA3 with PSK and CCMP), and setting the VLAN to 100 in the policy tag. These steps allow the client to associate successfully.
B
Enable SSID broadcast, change security to WPA2-PSK, and assign VLAN 20 in the policy tag.
Why wrong: This is incorrect because the client requires WPA3-Personal, not WPA2-PSK, and the correct VLAN is 100, not 20. Keeping VLAN 20 would still isolate the client on the wrong network.
C
Disable SSID broadcast, change security to WPA3-Personal, and assign VLAN 100 in the policy tag.
Why wrong: This is incorrect because the SSID is hidden and needs to be broadcast (enabled) for the client to discover it. Disabling broadcast would keep the SSID hidden, preventing association.
D
Enable SSID broadcast, change security to WPA3-Enterprise, and assign VLAN 100 in the policy tag.
Why wrong: This is incorrect because the client uses WPA3-Personal (PSK), not WPA3-Enterprise (802.1X). Configuring WPA3-Enterprise would require a RADIUS server and credentials, which are not available.

Correct answer & explanation
✓
Enable SSID broadcast, change security to WPA3-Personal, and assign VLAN 100 in the policy tag.
The WLAN was configured for WPA2-PSK with a hidden SSID, and the policy tag assigned VLAN 20 instead of VLAN 100. To fix: (1) Enable SSID broadcast with 'broadcast-ssid'. (2) Change security to WPA3-Personal by removing WPA2 and enabling WPA3 with 'security wpa wpa3' and 'security wpa psk set-ccmp'. (3) Assign VLAN 100 in the policy tag with 'vlan 100'. The client should then associate.
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.

✗Enable SSID broadcast, change security to WPA2-PSK, and assign VLAN 20 in the policy tag.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that the client uses WPA3-Personal, so changing to WPA2-PSK does not meet the requirement. Also, VLAN 20 is the wrong VLAN.
Why candidates choose this
Candidates might pick this if they overlook the client's WPA3 requirement and mistakenly think WPA2 is sufficient, or if they confuse the current VLAN with the desired one.
✗Disable SSID broadcast, change security to WPA3-Personal, and assign VLAN 100 in the policy tag.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that the SSID is currently hidden and the client cannot see it; enabling broadcast is required, not disabling.
Why candidates choose this
Candidates might think hiding the SSID adds security and choose to keep it hidden, but the client needs the SSID to be broadcast to associate.
✗Enable SSID broadcast, change security to WPA3-Enterprise, and assign VLAN 100 in the policy tag.Wrong answer — click to see why▾
Why this is wrong here
The specific factual error is that WPA3-Personal uses a pre-shared key, while WPA3-Enterprise requires 802.1X authentication. The client is configured for Personal mode.
Why candidates choose this
Candidates might confuse WPA3-Personal with WPA3-Enterprise, or think that Enterprise is always better, but the client's configuration dictates Personal.

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.
