Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 426

A high-speed network is often configured with a five-class QoS model. Which classes are used in the model?

Answer options

• A. voice, video, signaling critical data, and best-effort
• B. real-time, call-signaling, critical data, best-effort, and scavenger
• C. real-time, signaling, critical data, best-effort, and drop-class
• D. call-signaling, real-time, critical data, best-effort, and drop-class

Correct answer: B

Explanation

The correct answer is B, as it accurately lists the five classes used in a high-speed network's QoS model: real-time, call-signaling, critical data, best-effort, and scavenger. The other options either miss one of the classes or include incorrect terms that do not correspond to the standard QoS classifications.
