Full question →hardmultiple choiceObjective-mapped
A wireless client can associate to the correct corporate SSID and authenticate successfully, but receives an address from the guest network instead of the employee network. Which troubleshooting area is strongest?
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
Incorrect WLAN-to-role or VLAN mapping after successful authentication.
This is correct because the client is landing in the wrong logical segment after joining successfully.
B
Distractor review
The client must be using the wrong subnet mask manually.
This is wrong because the clue points to the wrong assigned network, not a manual host error.
C
Distractor review
The AP must be missing PPP encapsulation.
This is wrong because PPP is unrelated to WLAN client-to-VLAN assignment.
D
Distractor review
The issue is that STP root election failed.
This is wrong because STP root election is not the main clue in wrong WLAN segmentation after successful authentication.
Common exam trap
Common exam trap: OSPF can fail even when IP connectivity looks correct
OSPF neighbour formation depends on matching areas, timers, network type, authentication and passive-interface behaviour. Do not choose an answer only because the devices can ping.
Technical deep dive
How to think about this question
OSPF questions usually test the details that control adjacency and route selection. Read the neighbour state, area, router ID and interface configuration before deciding what is wrong.
KKey Concepts to Remember
- OSPF neighbours must agree on key parameters.
- Router ID selection can affect neighbour relationships and LSDB output.
- OSPF cost influences the preferred path.
- A route can appear in OSPF information but not become the installed route.
TExam Day Tips
- Check area mismatch first when OSPF adjacency fails.
- Review passive interfaces when a network is advertised but no neighbour forms.
- Use show ip ospf neighbor and show ip route clues carefully.

FAQ
Questions learners often ask
What does this 200-301 question test?
OSPF neighbours must agree on key parameters.
What is the correct answer to this question?
The correct answer is: Incorrect WLAN-to-role or VLAN mapping after successful authentication. — The strongest troubleshooting area is WLAN-to-policy or VLAN mapping. In practical terms, the radio join and authentication succeeded, but the client was placed into the wrong logical network afterward. That points to the mapping between the WLAN, user role, policy profile, or VLAN assignment rather than to pure RF or password failure. This is a realistic wireless troubleshooting scenario because the failure appears after successful association and authentication.
