Question 510

A high ceiling AP uses a down-tilted antenna incorrectly oriented into a concrete wall rather than the work area. Which response best follows from the observed evidence?

  1. Conduct measurements in representative shelf aisles with operational inventory and typical obstructions
  2. Correct antenna orientation and validate the resulting intended coverage footprint
  3. Interpret negative dBm levels correctly while considering noise and required modulation quality
  4. Investigate signal-to-noise ratio and non-Wi-Fi noise rather than absolute RSSI alone

Explanation

Correct Answer

B:

RF planning must account for bidirectional signal, noise, building attenuation and actual antenna propagation. In the described case, correct antenna orientation and validate the resulting intended coverage footprint resolves the identified control gap. Confirm with: A floor walk survey shows the required workstations receive usable coverage without excessive spill.

Incorrect Answers

A:

This is relevant to a separate rf fundamentals and propagation problem: A wireless scanner appears healthy near a bench AP but fails among tall metal shelving with moving stock. It does not directly address this incident, which instead calls for: Correct antenna orientation and validate the resulting intended coverage footprint.

C:

This is relevant to a separate rf fundamentals and propagation problem: An engineer treats an RSSI reading of negative 85 dBm as stronger than negative 55 dBm because eighty-five is larger. It does not directly address this incident, which instead calls for: Correct antenna orientation and validate the resulting intended coverage footprint.

D:

This is relevant to a separate rf fundamentals and propagation problem: A hospital AP shows acceptable RSSI but application performance falls when nearby industrial machinery raises the noise floor. It does not directly address this incident, which instead calls for: Correct antenna orientation and validate the resulting intended coverage footprint.

Question 511

A university network has low Successful Connects due to repeated ARP gateway failures despite successful association and DHCP. What is the most defensible next troubleshooting action?

  1. Restore the agreed service thresholds and use classifiers to drive real technical remediation
  2. Analyze Authorization latency and identity-provider response times rather than association failure count
  3. Trace gateway reachability and relevant ARP responses after address assignment
  4. Correlate handoff events, cell overlap and client capability near the affected aisle

Explanation

Correct Answer

C:

SLE troubleshooting links the selected failed classifier to real client and upstream dependency evidence before changing infrastructure. In the described case, trace gateway reachability and relevant ARP responses after address assignment resolves the identified control gap. Confirm with: A test client reaches its permitted default gateway and the ARP classifier recovers.

Incorrect Answers

A:
