QUESTION 2
You are a network technician at P4S. Study the exhibit above carefully, as the first step in verifying a local host configuration, you perform the ipconfig/all command on a computer. Answer the following questions by using the results of the command. For the following descriptions, which one is correct concerning how the router with the IP address 172.16.236.1 would send a data packet to this computer?
A. The router encapsulates the packet in a frame addressed to the MAC address of the next hop router on the path to the computer.

C. The router works at Layer3 of the OSI model and does not use Layer2 MAC addresses to send packets to the destination computer.
