When a Vocera badge performs a broadcast call in a properly configured VoWLAN using WLC v7.0, which two choices indicate how the QoS is marked? (Choose two.)

Upstream Vocera voice traffic is not marked as Best Effort - the badge explicitly marks its outgoing frames as DSCP EF to request high-priority voice treatment from the network infrastructure.

ToS CS4 (DSCP 32) is associated with a video class marking, not real-time voice traffic - Vocera badges use DSCP EF (DSCP 46) for upstream voice, not CS4.

Upstream voice frames from the Vocera badge are marked as DSCP EF (DSCP 46 - Expedited Forwarding), the standard per-hop behavior for real-time voice traffic, ensuring low latency and minimal jitter for the upstream audio path from the badge to the network.

The downstream direction of the broadcast call does not receive DSCP EF marking - only the upstream (badge-to-network) direction is marked EF, while downstream broadcast traffic is delivered at Best Effort.

The downstream direction of a Vocera broadcast call is treated as Best Effort because broadcast calls are system-initiated one-to-many announcements rather than bidirectional unicast voice sessions, and the WLC does not apply platinum or EF QoS marking to the downstream broadcast stream.

Silver QoS in the Cisco WLC model corresponds to video traffic - the downstream broadcast call is handled as Best Effort, not Silver, because broadcast voice announcements are not queued with the same priority as video or unicast voice sessions.
