mr Goodwill [35]

Answer:

Layer 2 destination address = 00-00-0c-94-36-ab

Layer 2 source address = 00-00-0c-94-36-bb

Layer 3 destination address = 172.16.20.200

Layer 3 source address = 172.16.10.200

Explanation:

To properly understand the given answer, let us define some terms used in the narrative of the question:

Subnet: The sub network or as popularly called subnet is a logical division of the internet protocol of a network into many different and smaller network. It is typically used to create partitions or subdivisions of large networks into bits.

PDU: The PDU can be said to be an abbreviation for the word power distribution unit or protocol data unit. It can also be refereed to as an IT device that possess many output ports or terminals. They are mostly used to distribute or transmit power or data to other operating devices with the telecommunication system.

Now referring back to the question asked and the image attached below, we can see that host a and b send their signal through subnet teachers while host c and d send their signal through subnet students thus,

Layer 2 destination address = 00-00-0c-94-36-ab

Layer 2 source address = 00-00-0c-94-36-bb

Layer 3 destination address = 172.16.20.200

Layer 3 source address = 172.16.10.200 are the correct destination.
