Question 870

A site exports a list of devices without their location or SSID labels and cannot identify which business unit suffered the outage. What corrective step most directly addresses the wireless fault?

  1. Use consistent success-rate and absolute-value reporting with explicit measurement definitions
  2. Compare historical client and SLE events during the actual failure intervals
  3. Use time-bounded Mist Insights intervals to examine the actual high-density event window
  4. Enrich or filter insights with stable site, WLAN and client identifiers

Explanation

Correct Answer

D:

Mist Insights need correct site, AP, client and time context and fresh telemetry to establish the real affected population. In the described case, enrich or filter insights with stable site, WLAN and client identifiers resolves the identified control gap. Confirm with: The exported case evidence maps each impacted client to the correct operating location and service.

Incorrect Answers

A:
