A network engineer is designing QoS for a multi-site deployment. The WAN link is 10 Mbps. The engineer needs to ensure that voice media gets priority, but also that signaling is not dropped during congestion. Which approach is most appropriate?

Put both signaling and media in the same priority queue with a combined policer.

Put media in a priority queue with a policer, and signaling in a separate class with bandwidth guarantee.

Use FIFO queuing and rely on the WAN provider's QoS.

Put signaling in a priority queue and media in a normal queue.

Which characteristic is more important for media traffic (RTP) than for signaling traffic in a Cisco collaboration network?

Very low packet loss and jitter

Guaranteed delivery of every packet

High reliability for call setup

A company uses a wireless network with WMM enabled. Voice calls are experiencing high jitter. The administrator checks the access point and finds that the voice queue is often empty, but the best-effort queue is congested. What is the most likely cause?

The voice traffic is being sent at a rate higher than the queue can handle.

The access point is not using WMM because it is disabled on the SSID.

Voice traffic is being marked with DSCP EF, but the AP is not mapping it to AC_VO.

The voice queue is not configured with enough bandwidth.
