Implementing Cisco Enterprise Wireless Networks (ENWLSI) — Question 201

An engineer configures QoS on an AireOS WLC v8.5. The engineer configures a WLAN for voice traffic and must set the data rates within the QoS profile. How should the data rates be configured to ensure that the QoS profile allows traffic to and from the wireless client?

Answer options

• A. The burst data rate should be configured before the average data rate.
• B. The burst data rate should be greater than or equal to the average data rate.
• C. Data rates should be applied per AP radio.
• D. The burst data rate should be set to a non-zero value.

Correct answer: B

Explanation

The correct answer is B because the burst data rate needs to be at least equal to the average data rate to ensure that voice traffic can be handled properly without interruptions. Options A and C are incorrect as they misrepresent the configuration order and scope of the data rate application. Option D is not sufficient on its own, as it does not address the relationship between burst and average data rates.
