Question 590

A wireless voice call has low RSSI but the WLAN team tries to repair it solely with DSCP priority rules. Which result would best establish that the correction succeeded?

  1. Peak traffic stays within safe utilization with acceptable application latency.
  2. Admitted calls meet quality objectives, while excess attempts receive controlled treatment.
  3. High-percentile latency and jitter remain within application requirements during transfer windows.
  4. Voice packet loss improves after coverage correction while approved QoS remains intact.

Explanation

Correct Answer

D:

This is an operational test of the required outcome rather than merely proof a setting exists. It checks that traffic priority cannot compensate for unusable wireless link quality no longer prevents the service.

Incorrect Answers

A:

This result may validate another network change, but it does not demonstrate recovery from the fault here: traffic priority cannot compensate for unusable wireless link quality.
