A network administrator is designing QoS for a converged network carrying voice, video, and data. The requirement is to ensure that voice media is never starved by other traffic, but also to prevent voice from monopolizing the link. Which queuing mechanism should be used?

Class-Based Weighted Fair Queuing (CBWFQ) with Low Latency Queuing (LLQ) for voice.

First-In First-Out (FIFO) queuing.

Priority Queuing (PQ) with strict priority for voice.

Weighted Fair Queuing (WFQ) for all traffic.

A network engineer is troubleshooting poor voice quality on a WAN link. The link is congested, and the engineer suspects that voice packets are being dropped. Which QoS mechanism would be most effective in preventing voice packet drops during congestion?

Increasing the interface MTU to reduce packet count.

Policing voice traffic to a lower rate.

Using Weighted Random Early Detection (WRED) on the voice queue.

Configuring a priority queue with a sufficient policer for voice.

A company uses a wireless network for VoIP. The network has many clients, and the administrator notices that voice quality degrades when the number of active clients increases. Which factor is most likely contributing to the degradation?

Limited bandwidth due to the shared wireless medium.

Increased interference from other wireless networks.

Incorrect DSCP marking on the access point.

Lack of WMM support on the clients.

How does QoS primarily mitigate the effects of packet loss on real-time media?

By increasing the jitter buffer size

By prioritizing media packets in queues

Part of the Media and QoS domain, which accounts for 10% of the 350-801 exam. Cisco does not publish an official question count, but from its 120-minute exam (~50–80 total, ~5–8 in this domain), expect 1–2 from this objective — we provide 20 practice questions to prepare you well beyond it.
