Question 6

Which characterstic of distributed class- based weighted fair queueing addresses jitter prevention?

A. It uses a priority queue for voice traffic to avoid jitter.

B. It provides additional granularity by allowing a user to create classes

C. It minimizes jitter by implementing a priority queue for voice traffic

Question 7

Exhibit.

Configuration of DNS is required to achieve a fully functional Cisco UCM system. Cisco UCM uses DNS to resolve fully qualified domain names to IP addresses for which destinations?

A. AAR

B. H.323

C. trunk

D. MRA

Correct Answer: B

Question 8

Refer to the exhibit. An administrator is attempting to register a SIP phone to a Cisco UCM but the registration is failing. The IP address of the SIP Phone is 10.117.34.222 and the IP address of the Cisco UCM is 10.0.101.10. Pings from the SIP phone to the Cisco UCM are successful. What is the cause of this issue and how should it be resolved?

A. An NTP mismatch is preventing the connection of the TCP session between the SIP phone and the Cisco UCM. The SIP phone and Cisco UCM must be set with identical NTP sources.

B. The certificates on the SIP phone are not trusted by the Cisco UCM. The SIP phone must generate new certificates.

C. DNS lookup for the Cisco UCM FQDN is failing. The SIP phone must be reconfigured with the proper DNS server.

D. An network device is blocking TCP port 5060 from the SIP phone to the Cisco UCM. This device must be reconfigured to allow traffic from the IP phone.

Correct Answer: D

Question 9

To provide high-quality voice and take advantage of the full voice feature set, which two access layer switches provide support?

A. Implement IP RTP header compression on the serial Interface to reduce the bandwidth required per voice call on point-to-point links.

B. Use 802, 1Q trunking and 802.1p for proper treatment of Layer 2 CoS packet marking on ports with phones connected.

C. Deploy RSVP to improve VoIP QoS only where it can have a positive impact on quality and functionality where there is limited bandwidth and frequent network congestion.

D. Use multiple egress queues to provide priority queuing of RTP voice packet streams and the ability to classify or reclassify traffic and establish a network trust boundary.

E. Map audio and video streams of video calls (AF41 and AF42) to a class-based queue with weighted random early detection.

Correct Answer: B,D
