Validate supported AP uplink failover and matching VLAN availability on the alternate port.
Reassign nonoverlapping channels using a surveyed reuse plan.
Rebalance clients across eligible APs and assess airtime fairness.

Explanation

Correct Answer

Capacity is constrained by shared airtime, not simply signal strength. The engineer should rebalance clients across eligible APs and assess airtime fairness.

Incorrect Answers

TWT coordinates scheduled wake/sleep periods to reduce contention and energy use. It is not a direct remedy for the condition described.

AP resiliency requires compatible management and user VLAN reachability after switching links. It is not a direct remedy for the condition described.

Reduce noise/interference or reposition the cell.
Consider 802.11r/k/v support and authentication-path tuning.
Inspect flow-hash distribution and per-member traffic.

Explanation

Correct Answer

Roaming performance depends on scan, authentication and mobility handling. The engineer should consider 802.11r/k/v support and authentication-path tuning.

Incorrect Answers

Optimization requires a measured baseline to distinguish improvement from noise. It is not a direct remedy for the condition described.

SNR combines received signal strength with background noise. It is not a direct remedy for the condition described.

LAG hashing keeps a flow on one member and does not split one flow packet by packet. It is not a direct remedy for the condition described.

Question 445

After completing the planned work for this situation—a building has many adjacent APs with identical high EIRP—how should success be checked?

Compare client IP, gateway and effective role before/after roam.
Measure concurrent client distribution and busy time per radio.
Compare association band, noise and retry rates for affected clients.
Map RSSI overlap and co-channel busy time after changes.

Explanation

Correct Answer

Cell overlap depends on EIRP, antenna pattern and building attenuation. Map RSSI overlap and co-channel busy time after changes directly tests the desired behavior.

Incorrect Answers

L3 or policy changes during roaming can interrupt sessions beyond RF association delay. That observation tests a different condition, not the required result.

Capacity is constrained by shared airtime, not simply signal strength. That observation tests a different condition, not the required result.

The 5 GHz band offers more usable channel choices and often less 2.4 GHz interference. That observation tests a different condition, not the required result.

Question 446

During campus implementation, a WLAN has high peak Mbps but poor application response time. What should the engineer configure or correct?

Evaluate latency, loss, jitter and airtime rather than throughput alone.
Consolidate SSIDs when authorization roles can differentiate users.
Re-mark untrusted traffic at the first managed boundary.
Inspect flow-hash distribution and per-member traffic.

Explanation

Correct Answer

Application quality depends on timing and reliability as well as bandwidth. The engineer should evaluate latency, loss, jitter and airtime rather than throughput alone.

Incorrect Answers

More SSIDs increase beacon/management overhead. It is not a direct remedy for the condition described.

QoS trust should be granted to known sources, not arbitrary clients. It is not a direct remedy for the condition described.

LAG hashing keeps a flow on one member and does not split one flow packet by packet. It is not a direct remedy for the condition described.

Question 447

A network team reports the following condition: An AP's automated RF power is too high in an open office. Select the most appropriate response.

Verify client DNS option, resolver reachability and suffix.
Review ARM/AirMatch bounds and actual cell overlap.
Use supported BSS transition management with a suitable candidate list.
Balance AP power with realistic client transmit limits.

Explanation

Correct Answer

Excess transmit power can enlarge contention cells and delay roaming. The engineer should review ARM/AirMatch bounds and actual cell overlap.

Incorrect Answers

DNS failure can appear as WLAN failure despite correct radio and IP connectivity. It is not a direct remedy for the condition described.

802.11v can suggest a better BSS, but the client decides whether to comply. It is not a direct remedy for the condition described.

Question 448

During campus implementation, two static paths to one prefix have different administrative distances. What should the engineer configure or correct?

Choose the intended preferred route distance for failover policy.
Configure appropriate area or external route summarization.
Verify OSPF activation, area and Layer 3 adjacency parameters.
Make user-facing OSPF interfaces passive while advertising the prefix.

Explanation

Correct Answer

Lower administrative distance normally wins among comparable route sources. The engineer should choose the intended preferred route distance for failover policy.

Incorrect Answers

Summarization reduces route entries and update churn where topology permits. It is not a direct remedy for the condition described.

OSPF peers require compatible interface participation and topology. It is not a direct remedy for the condition described.

Passive OSPF suppresses adjacency exchange on the selected interface. It is not a direct remedy for the condition described.

Question 449
