Question 1100

A site owner wants proof that a roaming tuning change helped but the analysis compares devices in dissimilar buildings. What is the most defensible next troubleshooting action?

  1. Preserve and correlate event history across the outage for recurrence analysis
  2. Use a comparable test cohort and equivalent time-window baseline for postchange evaluation
  3. Join configuration change scope with client and AP telemetry rather than attributing impact globally
  4. Drill from SSID-level Insights to the individual AP and client contribution

Explanation

Correct Answer

B:

Mist Insights need correct site, AP, client and time context and fresh telemetry to establish the real affected population. In the described case, use a comparable test cohort and equivalent time-window baseline for postchange evaluation resolves the identified control gap. Confirm with: The outcome quantifies the target clients' transition improvement without mixing unrelated sites.

Incorrect Answers

A:

This is relevant to a separate mist network events and insights problem: A wireless incident report captures only the final resolved alarm and omits the sequence of repeated AP disconnects. It does not directly address this incident, which instead calls for: Use a comparable test cohort and equivalent time-window baseline for postchange evaluation.

C:

This is relevant to a separate mist network events and insights problem: A Wi-Fi report shows an SLE classifier worsened after changing power, but no one checks which APs actually inherited that policy. It does not directly address this incident, which instead calls for: Use a comparable test cohort and equivalent time-window baseline for postchange evaluation.

D:

This is relevant to a separate mist network events and insights problem: A report groups all WLAN traffic by SSID and hides that one AP has extremely high retransmission rates. It does not directly address this incident, which instead calls for: Use a comparable test cohort and equivalent time-window baseline for postchange evaluation.

Question 1101

A WLAN administrator interprets quiet RF at 3 AM as enough evidence to accept a capacity plan for lunchtime crowds. Which configuration or control should the operator select?

  1. Evaluate cell coverage, steering support and client decisions before changing WAN capacity
  2. Compare equivalent pre- and postchange periods while excluding the transient restart interval
  3. Allow a supported RRM channel plan that accounts for RF overlap and available spectrum
  4. Use representative peak-hour client and airtime measurements before finalizing RRM choices

Explanation

Correct Answer

D:

RRM choices balance interference, legal channel/power limits, cell reuse, client needs and actual service-impact evidence. In the described case, use representative peak-hour client and airtime measurements before finalizing RRM choices resolves the identified control gap. Confirm with: Busy-hour SLE and channel occupancy meet the intended service goals in the mapped location.

Incorrect Answers

A:

This is relevant to a separate radio resource management (rrm) problem: An AP reports excessive clients despite a lightly loaded nearby AP, and the team blames upstream bandwidth without looking at RF association distribution. It does not directly address this incident, which instead calls for: Use representative peak-hour client and airtime measurements before finalizing RRM choices.

B:

This is relevant to a separate radio resource management (rrm) problem: A team treats lower channel utilization immediately after an AP reboot as proof that permanent interference has disappeared. It does not directly address this incident, which instead calls for: Use representative peak-hour client and airtime measurements before finalizing RRM choices.

C:

This is relevant to a separate radio resource management (rrm) problem: A campus statically assigns the same 5 GHz channel to adjacent APs and reports severe co-channel contention during lectures. It does not directly address this incident, which instead calls for: Use representative peak-hour client and airtime measurements before finalizing RRM choices.
