Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 412

What is the function of DiffServ?

Answer options

• A. It automatically identifies traffic.
• B. It guarantees end-to-end bandwidth for traffic.
• C. It categorizes traffic.
• D. It provides reserve bandwidth by using RSVP.

Correct answer: C

Explanation

The correct answer is C because DiffServ is designed to categorize and prioritize different types of network traffic, enhancing Quality of Service (QoS). Option A is incorrect as DiffServ does not automatically identify traffic types; instead, it relies on predefined classifications. Options B and D are also incorrect as they refer to functions associated with other protocols, like RSVP, and not DiffServ specifically.
