Exhibit
Client observations: - Joined SSID: Corp-Employee - Authentication: success - Assigned IP: 10.90.200.44/24 Expected employee subnet: 10.90.10.0/24 Observed guest subnet: 10.90.200.0/24
Based on the exhibit, what is the strongest explanation for why the client cannot obtain a correct address on the employee WLAN?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
The client is being placed into the wrong policy or VLAN after successful authentication.
This is correct because the client joined successfully but landed in the guest-style subnet instead of the employee subnet.
B
Distractor review
The client must have the wrong local subnet mask typed manually.
This is wrong because the symptom is wrong network placement after successful assignment, not just a mask typo.
C
Distractor review
The AP must be missing STP root guard.
This is wrong because STP root guard is not the primary clue in WLAN client-to-subnet placement.
D
Distractor review
The WLAN can function only if BGP is configured on the client.
This is wrong because client WLAN access does not depend on host-side BGP configuration.
Common exam trap
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.
Technical deep dive
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.

FAQ
Questions learners often ask
What does this 200-301 question test?
Access ports place end devices into a single VLAN.
What is the correct answer to this question?
The correct answer is: The client is being placed into the wrong policy or VLAN after successful authentication. — The strongest explanation is that the client is being mapped into the wrong logical network or policy after joining the WLAN. In practical terms, the client associated successfully, but it received an address from the guest space instead of the employee space. That suggests a policy, role, or VLAN mapping error rather than a simple radio or password problem. This is a realistic WLAN segmentation issue and a good simulation-style item because the failure happens after successful join behavior.
