Question 500
At East Student Center, a mixed-generation WLAN has a few low-rate clients consuming most shared radio time. Which change-management constraint best guards against recurrence?
Explanation
Correct Answer
For East Student Center, the decisive mechanism is Airtime fairness QoS. Wireless performance must account for airtime occupancy as a shared resource. Avoid starving an approved low-rate medical or industrial device is an enduring limitation on the operational risk, not simply a one-time passing test.
Incorrect Answers
This is relevant to Strict priority queue use, where priority scheduling affects service latency but requires careful queue sizing In the East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource
This is relevant to DSCP trust boundary, where qoS trust boundaries determine which received packet markings affect forwarding priority In the East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource
This is relevant to WMM access categories, where 802.11e WMM prioritizes wireless contention via different access categories In the East Student Center case, A precaution for another failure mode is not the enduring boundary needed here. The specific mechanism is wireless performance must account for airtime occupancy as a shared resource
