What the exam tests

What to know about Media And Qos

QoS questions usually test traffic classification (DSCP/CoS), queuing strategies, policing vs shaping and where each mechanism is applied.

DSCP and CoS marking and trust boundaries.

Queuing mechanisms: FIFO, WFQ, CBWFQ, LLQ.

Policing (drops excess) vs shaping (delays excess).

Where QoS is applied: ingress, egress, LAN, WAN.

Watch out for

Common Media And Qos exam traps

▸Policing drops traffic; shaping buffers it — they solve different problems.
▸DSCP EF (46) is for voice; AF classes are for data tiers.
▸QoS must be configured end-to-end to be effective.
▸CoS values are Layer 2; DSCP is Layer 3.

Media And Qos questions

You are configuring a Cisco IOS router to perform QoS marking for voice traffic originating from a local PBX. You need to ensure that the voice traffic is marked as DSCP EF. Which configuration command correctly applies this in a policy-map?

You are configuring a Cisco gateway to handle voice traffic. You need to ensure that the gateway trusts DSCP markings from the incoming IP phone. Which command is used on the interface?

Which parameter in the CUCM 'Service Parameters' section controls the default region bandwidth for audio calls?

Which TWO of the following are true regarding Cisco Unified Communications Manager (CUCM) Locations?

Which TWO of the following are examples of call signaling protocols that require specific QoS treatment?

Which command allows an administrator to view the current status of registered media resources, such as transcoders, on a Cisco IOS gateway?

You are implementing a QoS policy on a WAN edge router. You have a requirement to prioritize video traffic. Which queueing mechanism is recommended by Cisco to minimize jitter and latency for video streams?

In a Cisco Collaboration environment, what is the purpose of the 'Media Termination Point' (MTP) in relation to call signaling?

A network administrator is troubleshooting one-way audio issues between a Cisco IP Phone and a Cisco TelePresence endpoint. The path traverses a router with a configured class-map. Which command would you use to verify the packet markings on the ingress interface?

You are configuring a Media Resource Group List (MRGL) in CUCM to allow for transcoding. A call is placed between two endpoints where one supports G.711 and the other only supports G.729. If the MRGL contains a Transcoder, what must be configured to ensure the call succeeds?

What is the default behavior for DSCP markings on traffic originating from a Cisco IP Phone that has not been configured with specific QoS policies?

You are configuring QoS for a Cisco Unified Communications Manager (CUCM) deployment. You need to ensure that audio media traffic between endpoints is marked correctly. Which DSCP value should be assigned to RTP audio traffic according to the Cisco SRND best practices?

Which DSCP value is recommended for Call Signaling traffic in a Cisco Unified Communications network?

When using 'RSVP' for Call Admission Control (CAC), what happens if the available bandwidth on the path is less than the requested amount?

An administrator needs to enforce a bandwidth limit for video calls at a specific site in CUCM. Which configuration object should be used?

You are troubleshooting a scenario where video quality is degrading during periods of high data utilization. You identify that video traffic is being dropped in the network. What is the most likely cause if you are using CBWFQ?

In a multi-site deployment, you have a requirement to transcode between G.711 and G.729. If the transcoder resources are exhausted, what is the expected outcome for a new call requiring this conversion?

When configuring a policy-map for voice traffic, which command is used to assign a specific bandwidth guarantee to a class?

You are configuring a Cisco IOS router to perform traffic shaping for voice traffic. Why is traffic shaping often used in conjunction with queuing?

Which feature in CUCM is used to block calls when the available bandwidth in a location is exceeded?
