Which two statements are correct about a Routing Engine? (Choose two.)

The Routing Engine (RE) is the control-plane component of a Juniper device. It handles all management and protocol processing, maintains the routing and forwarding tables, and exchanges route information with the Packet Forwarding Engine (PFE); it does not forward transit or CoS-handled traffic itself.

B. CoS classification/queuing is performed in the PFE, not the RE.

C. Transit packet forwarding occurs in the PFE; the RE is not in the data path.
