Which option correctly describes a switching method?
- cut-through: makes a forwarding decision after receiving the entire frame
- cut-through: provides the flexibility to support any mix of Ethernet speeds
- store-and-forward: forwards the frame immediately after examining its destination MAC address
- store-and-forward: ensures that the frame is free of physical and data-link errors
Explanation: Store-and-forward switching performs an error check on an incoming frame after receiving the entire frame on the ingress port. Switches which use this method have the flexibility to support any mix of Ethernet speeds. The cut-through method begins the forwarding process after the destination MAC address of an incoming frame is looked up and the egress port has been determined.
