Refer to the exhibit.
What does R1 use as the MAC address of the destination when constructing the frame that will go from R1 to Server B?
- If the destination MAC address that corresponds to the IPv4 address is not in the ARP cache, R1 sends an ARP request.
- The packet is encapsulated into a PPP frame, and R1 adds the PPP destination address to the frame.
- R1 uses the destination MAC address of S1.
- R1 leaves the field blank and forwards the data to the PC.
Answers Explanation & Hints:
Communication inside a local network uses Address Resolution Protocol to obtain a MAC address from a known IPv4 address. A MAC address is needed to construct the frame in which the packet is encapsulated.
