Please provide an explanation for which interfaces a frame will be forwarded on so I can understand

Let us presume that we have a self-learning switch with four interfaces. Given the following switch table, please indicate in each subproblem below which interface(s) a frame destined to the indicated MAC address will be forwarded on. Presume that the switch does not learn any new information during the time frame of these questions.

Answer to each is one of the following solutions: {1}, {2}, {3}, {4}, {2,3,4}, {1,2,3,4}

part a) To 5B:CC:44:83:C8:34 and received on port 1

part b) To CD:00:77:9E:2E:0D and received on port 3
