Question 190
At Riverside Building, a wireless SSID has no voice prioritization so delay increases during heavy uploads. Which practical change is best suited to this topology and its constraints?
Explanation
Correct Answer
For Riverside Building, the decisive mechanism is WMM access categories. 802.11e WMM prioritizes wireless contention via different access categories. Map appropriate application classes to supported WMM AC_VO/AC_VI and wired QoS policy establishes the needed configuration in the case rather than merely measuring a symptom.
Incorrect Answers
This is relevant to Band steering under load, where band steering can guide dual-band association but depends on real RF and client support In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories
This is relevant to Multicast-to-unicast tradeoff, where multicast-to-unicast can improve delivery to small receiver groups but adds per-recipient work In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories
This is relevant to RF power tuning, where excess transmit power can increase interference and sticky-client behavior In the Riverside Building case, Changing that neighboring feature does not implement the missing function. The specific mechanism is 802.11e WMM prioritizes wireless contention via different access categories
