D is the best choice. Prioritizing voice and video is essential.

A covers all bases. Real-time is key for performance.
NA

C seems right to me. Drop-class is a valid category.
DA

I thought it was call-signaling instead of signaling?

The five classes are voice, video, signaling, critical data, and best-effort.

I'm going with A. The five-class QoS model is like a fancy way of saying "we're going to prioritize the important stuff and let the rest fight for scraps."

Haha, I bet the network admin who came up with these class names was having a bit too much fun. Scavenger class? Really?
AN

Hmm, I think the answer is B. Real-time, signaling, critical data, best-effort, and drop-class are the classes in the five-class QoS model.
JO

I'm pretty sure the answer is D. Voice, video, signaling, critical data, and best-effort are the classes used in the five-class QoS model.
MA

The correct answer is A. The five-class QoS model includes real-time, call-signaling, critical data, best-effort, and scavenger classes.

I feel like "call-signaling" was mentioned in our study materials, but I can't recall if it was in the right context for this question.
IO

I'm pretty confident about this. The five-class QoS model uses real-time, call-signaling, critical data, best-effort, and scavenger classes. Option A is the correct answer.
CO
Cora

This is a tricky one. I know the five-class model covers the main traffic types, but I'm not sure of the specific class names. I'll have to make an educated guess and go with option D.
KE
Kenneth

Okay, I've got it. The five-class model has real-time, signaling, critical data, best-effort, and a drop-class. So I'll choose option B.
FL
Floyd

I think it's A. Those classes make sense for QoS.
RA
Raylene

I think the five classes include real-time and best-effort, but I'm not sure about the others.
GA
Garry

I remember practicing a question like this, and I think option D sounds familiar with voice and video classes.
MA
Maricela

I’m leaning towards option A, but I’m confused about whether "scavenger" is the correct term instead of "drop-class."
DO
Dominque

Hmm, I'm a bit confused. I remember there being a voice and video class, but I can't recall the exact names of the other three. I'll have to think this through carefully.
JA
Janella

I think I know this one. The five-class QoS model usually has real-time, call-signaling, critical data, best-effort, and scavenger classes, so I'll go with option A.
SH
