The following commands are used to configure the codec on a Cisco Unified Border Element to prefer the G.711 ulaw and use G.711 alaw as the next codec:
Code snippet
voice class codec 100
codec preference 1 g711ulaw
codec preference 2 g711alaw
The voice class codec 100 command creates a new voice class with the ID of 100. The codec preference 1 g711ulaw command sets the preference for the G.711 ulaw codec to 1. The codec preference 2 g711alaw command sets the preference for the G.711 alaw codec to 2.

Totally agree with B, voice traffic needs that priority!

A is interesting, but not really about jitter prevention.

Wait, does this really prevent jitter? Sounds too good to be true.

I think C is basically the same as B.

B is correct, priority queues help with voice traffic.

I practiced a similar question, and I think it was about prioritizing voice traffic to manage jitter. So, could it be B or C?

I feel like the granularity aspect is important too, but I can't remember if that relates directly to jitter prevention.

I'm not entirely sure, but I remember something about priority queues helping with jitter. Maybe it's C?

I think the answer might be B, since it mentions minimizing jitter for voice traffic, which is really important.

I'm pretty confident that the answer is option C. Distributed class-based weighted fair queueing uses a priority queue for voice traffic to avoid jitter, which is a critical requirement for real-time communications.

Okay, I think I've got this. The key characteristic that addresses jitter prevention is the use of a priority queue for voice traffic. That should help minimize the jitter experienced by real-time applications.

Hmm, I'm a bit confused by the wording of this question. I'll need to review my notes on the different features of distributed class-based weighted fair queueing to figure out which one is specifically related to jitter prevention.

This looks like a tricky question on distributed class-based weighted fair queueing. I'll need to think carefully about the characteristics that address jitter prevention.

I remember learning about this in class, but I'm drawing a blank on the specifics right now. Gotta focus and think it through.

I think option A looks familiar because it includes both dot1q encapsulation and the rewrite command. But isn't there something about the interface type that could be incorrect?

I'm going with C) - can't go wrong with a good old priority queue for voice traffic!

Haha, I bet the right answer is something really obscure that none of us would ever guess. Gotta love these tricky certification exams!

Hmm, that makes sense too. Custom class definition could indeed help address jitter in distributed class-based weighted fair queueing.
AL

I disagree, I believe the answer is D. Custom class definition provides additional granularity to prevent jitter.
