What are two examples of transit traffic?

Transit traffic refers to data packets that pass through a device or interface without being altered, primarily moving from one interface to another. In this context, the correct examples of transit traffic would involve data that originates on one interface, traverses the device, and exits through a different interface.

One example is SCPT traffic that enters one interface and exits another, as it illustrates the definition of transit traffic, where the data does not stop or get processed for management purposes; it simply flows through the router. This flow is essential in understanding how traffic is routed across a network.

The other choices do not fit the definition of transit traffic. For instance, SFTP traffic that enters and exits the same interface is more indicative of local traffic or traffic handled internally, rather than transit. Management traffic focuses on maintaining and monitoring the health of the router and does not pass through as user data. Backup traffic in a separate VLAN may involve data designated for a different purpose, making it distinct from the traffic that is simply crossing from one interface to another without being manipulated.
