Questions # 31:

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

Options:

A.

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.

B.

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

C.

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

D.

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.

E.

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

Questions # 32:

Location-based call admission control is used in Cisco UCM to control the amount of bandwidth allowed between predefined locations. What must be considered when calculating the number of calls that can be made?

Options:

A.

A limit of 900 kb is the total amount of bandwidth used for the sum of calls. The use of compression does not impact the amount of calls because only the codec definition is considered when calculating the CAC in Cisco UCM

B.

A limit of 900 kb is the total amount of actual used RTP traffic so the oversubscription can be done for multiple calls adding its maximum RTP stream requirements.

C.

A limit of 900 kb is the total amount of bandwidth used for the sum of the media and signaling in the calls The system allows for an actual of 20% overhead of IP packet headers This is to compare the use of ISDN lines with no IP overhead.

D.

A limit of 900 kb is the total amount of bandwidth used for the sum of calls of the defined codec including headers and media traffic

B.

Video traffic can tolerate up to 10% packet loss and latency of 10 seconds

C.

Video trafic can tolerate up to 5% packet loss and latency of 5 seconds

D.

Video traffic can tolerate a packet loss of up to 1% and latency of 150 milliseconds
