Implementing and Operating Cisco Enterprise Network Core Technologies (ENCOR) — Question 987

Which QoS component alters a packet to change the way that traffic is treated in the network?

Answer options

• A. policing
• B. classification
• C. marking
• D. shaping

Correct answer: C

Explanation

The correct answer is C, marking, as it specifically involves modifying packets to assign them different priority levels or classes for traffic management. Policing refers to monitoring traffic and enforcing limits, classification is about identifying traffic types, and shaping smooths out traffic bursts, but none of these directly modify packet attributes like marking does.
