Question

What’s the difference between the target MAC address in the ARP section from deliverable 6 and the destination in the Ethernet header from deliverable 7? Why is this so?

a) They serve different protocol layers
b) They both identify the same device
c) The ARP address is physical, Ethernet is logical
d) The ARP address is temporary, Ethernet is permanent

Answer 1

The target MAC address in the ARP section and the destination in the Ethernet header serve different protocol layers. The ARP address is physical and temporary, while the Ethernet address is logical and permanent.

Step-by-step explanation:

The target MAC address in the ARP section and the destination in the Ethernet header serve different protocol layers.

The ARP address is physical and represents the network layer, while the Ethernet address is logical and represents the data link layer.

The ARP address is temporary and can change, while the Ethernet address is permanent and uniquely identifies a device.
