Implementing and Operating Cisco Collaboration Core Technologies (CLCOR) — Question 326

What is NBAR?

Answer options

• A. It controls the forwarding of routed packets
• B. It collects traffic flow statistics on routing devices
• C. It allows asymmetric flows that have stateful protocols
• D. It intelligently classifies traffic from different applications

Correct answer: D

Explanation

The correct answer is D because NBAR (Network Based Application Recognition) is specifically designed to classify and recognize different types of application traffic. Option A is incorrect as it pertains to packet forwarding, while B refers to traffic statistics rather than classification, and C involves asymmetric flows but does not capture the main function of NBAR.
