Consider the operation of an Ethernet switch connecting six nodes labeled A through F in a star topology. The switch table is initially empty. Show the state of the switch table before and after the following events: i. Node A sends a frame to node E, ii. Node E replies to node A. iii. Node C sends a frame to node A, iv. Node A replies to node C.

For each event, identify the link(s) on which the transmitted frame will be forwarded and justify your answers.
