Exam 300-430 topic 1 question 24 discussion

In Cisco Wireless QoS, different QoS profiles are used to prioritize traffic based on its requirements. The Gold QoS profile is recommended for video traffic, ensuring low latency and jitter while maintaining a good balance of network resources. Why is Gold the Correct Choice? The given bandwidth requirement is 391,595,179 bps (≈ 392 Mbps), which is typical for high-quality video applications. Cisco QoS Profiles: Platinum (Voice) – Highest priority, used for VoIP with very low latency. Gold (Video) – Optimized for video applications, ensuring smooth playback and minimal buffering. ✅ Silver (Best Effort) – Default QoS, used for general web browsing and email. Bronze (Background) – Lowest priority, used for non-critical data like bulk file transfers. Since video streaming needs low latency but not as strict as voice, Gold QoS is the most appropriate choice.

From the official cisco study guide: You will probably never use Gold unless you deploy a WLAN dedicated to video traffic.

From the controller GUI itself. Platinum (voice) Gold (Video) Silver (Best Effort) Bronze (Background)

B. Gold, there is no bandwidth restriction on the default Gold profile.

Gold profile=Maximum DSCP Ceiling of 34. DSCP to WMM UP says Interactive Video DSCP=34, UP=5 and AC=Video AC_VI.

To determine the appropriate QoS marking, we need to calculate the bandwidth required for the application in kilobits per second (kbps), and then map that value to the appropriate QoS class. 391595179 bits per second = 391595179 / 1000 kbps = 391595.179 kbps Based on Cisco's recommended QoS values, a bandwidth requirement of 391595.179 kbps corresponds to the Platinum QoS class. Therefore, the correct answer is A. Platinum.
