QUESTION 269

When provisioning for Interactive-Video (e.g. video conferencing traffic) which three statements depicts the correct requirements?

 

A.

Loss should be no more than 1 percent.

B.

One-way latency should be no more than 150 ms

C.

Jitter should be no more than 30 ms

D.

Loss should be no more than 3 percent

E.

One-way latency should be no more than 75 ms

F.

Jitter should be no more than 300 ms

 

Correct Answer: ABC

Explanation:

Interactive Video

When provisioning for Interactive Video (IP Videoconferencing) traffic, the following guidelines are recommended:

 

Interactive Video traffic should be marked to DSCP AF41; excess Interactive-Video traffic can be marked down by apolicer to AF42 or AF43.

Loss should be no more than 1 %.

One-way Latency should be no more than 150 ms.

Jitter should be no more than 30 ms.

Overprovision Interactive Video queues by 20% to accommodate bursts Because IP Videoconferencing (IP/VC) includes a G.711 audio codec for voice, it has the same loss, delay, and delay variation requirements as voice, but the traffic patterns of videoconferencing are radically different from voice.

 

 

QUESTION 270

What is the definition of “jitter”?

 

A.

The totalend-to-end delay

B.

The time it takes for the bits to transit the physical media.

C.

The delay caused by placing the bits on the wire.

D.

The variation
s of delay.

 

Correct Answer: D
