Question
A company is collecting the requirements for an on-premises event. During the event, a wireless client connected to a dedicated WLAN will run a video application that will need on average 391595179 bits per second to function properly. What is the QoS marking that needs to be applied to that WLAN?

Why each option
This question tests knowledge of Cisco WLC QoS profile tiers and which tier maps to video traffic.
Bronze is the lowest QoS tier used for background or scavenger traffic, not suitable for real-time video streams.
Platinum is reserved for voice traffic (DSCP EF/46) and represents the highest-priority QoS tier, which would be over-provisioning for a video application.
Silver maps to best-effort traffic (DSCP 0) and does not provide the prioritization guarantees required for a real-time video application.
Gold is the Cisco WLC QoS profile designated for video traffic, mapped to DSCP AF41 (DSCP 34). Video applications require higher priority than best-effort data but lower priority than voice, which is exactly what the Gold tier provides in Cisco's four-tier QoS model (Platinum, Gold, Silver, Bronze).
