In Junos OS, transit traffic is handled by both the Routing Engine (RE) and the Packet Forwarding Engine (PFE), so the correct answer is C.
The RE is responsible for the control plane functions such as routing protocols, management services, and software processes. It maintains the routing table, which contains information about the network topology and the best path to reach the destination network. The RE also processes packets that are destined for the device itself, such as management traffic or packets to the device's loopback address.
The PFE, on the other hand, is responsible for the data plane functions such as packet forwarding and processing. It handles the transit traffic that passes through the device, routing packets based on the information in the routing table and forwarding them out the appropriate interface. The PFE also performs packet filtering, policing, and other packet-processing functions.
In summary, both the RE and PFE play important roles in handling transit traffic in the Junos OS. The RE provides control plane functions and maintains the routing table, while the PFE is responsible for packet forwarding and processing. Together, they work to ensure efficient and accurate transit of traffic through the device.
