Question 50

A warehouse client has strong RSSI but its successful connection percentage falls sharply during a RADIUS outage. What should the engineer investigate or configure next?

  1. Audit measurement coverage and disconnected AP inventory before interpreting the improvement
  2. Investigate the Successful Connects authorization classifier rather than channel coverage
  3. Include the relevant WLAN, site and affected client population in the SLE context
  4. Inspect client received signal strength and uplink/downlink asymmetry within the Coverage classifiers

Explanation

Correct Answer

B:

Wireless SLEs measure defined client-experience success and classifiers; different metrics and denominators are not interchangeable. In the described case, investigate the Successful Connects authorization classifier rather than channel coverage resolves the identified control gap. Confirm with: Client and EAP events show authorization failures during the service interruption.

Incorrect Answers

A:

This is relevant to a separate wireless assurance sle metric interpretation problem: A site reports 100 percent successful wireless connects after every failing AP stopped reporting telemetry. It does not directly address this incident, which instead calls for: Investigate the Successful Connects authorization classifier rather than channel coverage.

C:

It does not directly address this incident, which instead calls for: Investigate the Successful Connects authorization classifier rather than channel coverage.

D:

This is relevant to a separate wireless assurance sle metric interpretation problem: A university observes low Coverage SLE for scanners even though the average AP power is at its configured maximum. It does not directly address this incident, which instead calls for: Investigate the Successful Connects authorization classifier rather than channel coverage.

Question 51

An API dashboard reads only the first response page and falsely reports that half the AP fleet is missing. Which response best follows from the observed evidence?

  1. Validate organization ownership and explicit resource identity before any high-impact API deletion
  2. Use scoped authentication and enforce separate privileges for read and write API methods
  3. Rotate the exposed credential and replace it with protected minimally scoped automation access
  4. Follow the documented collection pagination and filter semantics for Mist resources

Explanation

Correct Answer

D:

Mist API operations require the supported method, region, stable resource identity, scoped credentials and post-write readback. In the described case, follow the documented collection pagination and filter semantics for Mist resources resolves the identified control gap. Confirm with: A complete authorized inventory query matches the corresponding portal count across all pages.

Incorrect Answers

A:

Question 55

A hospital handset fails enterprise WLAN authentication while the AP radio reports good coverage. Which action should the specialist recommend FIRST?

  1. Test approved DNS server reachability and client configuration without changing SSID authentication
  2. Roll back broad changes and apply a scoped compatible exception after client capability assessment
  3. Use client and RADIUS timelines to isolate EAP authorization rather than increasing transmit power
  4. Find and modify the authoritative WLAN template binding and verify effective AP configuration

Explanation

Correct Answer

C:

Wireless faults should be isolated at the actual RF, association, authorization, DHCP, policy or application stage. In the described case, use client and RADIUS timelines to isolate EAP authorization rather than increasing transmit power resolves the identified control gap. Confirm with: The rejected EAP step is identified and a valid managed identity completes login.

Incorrect Answers

A:

This is relevant to a separate wlan configuration and troubleshooting problem: A client can reach internal resources over the WLAN but external hostnames never resolve. It does not directly address this incident, which instead calls for: Use client and RADIUS timelines to isolate EAP authorization rather than increasing transmit power.
