What is responsible for processing multicast transit traffic?

Answer options

• A. control plane
• B. management plane
• C. RE
• D. PFE

Correct answer: D

Explanation

The Packet Forwarding Engine (PFE) is responsible for processing multicast transit traffic as it handles the actual data forwarding functions. The control plane manages routing and signaling, while the management plane is used for network management tasks, and the Routing Engine (RE) primarily focuses on the control functions rather than data traffic.
