Imagine a network with two routers that are connected with a point-to-point HDLC serial link.
Each router has an Ethernet, with PC1 sharing the Ethernet with Router1 and PC2 sharing the Ethernet
with Router2. When PC1 sends data to PC2, which of the following is true?
- A.Router1 strips the Ethernet header and trailer off the frame received from PC1, never to be used again.
- B.Router1 encapsulates the Ethernet frame inside an HDLC header and sends the frame to Router2, which extracts the Ethernet frame for forwarding to PC2.
- C.Router1 strips the Ethernet header and trailer off the frame received from PC1, which is exactly re- created by Router2 before forwarding data to PC2.
- D.Router1 removes the Ethernet, IP, and TCP headers and rebuilds the appropriate headers before forwarding the packet to Router2.
