Andrew S. Tanenbaum Edition 5th Chapter 5 Question 35 (Page No. 493)
You have just explained the ARP protocol to a friend. When you are all done, he says: ‘‘I’ve got it. ARP provides a service to the network layer, so it is part of the data link layer.’’ What do you say to him?

A PC has just booted up and wants to communicate with a host on a remote subnet. The PC knows the IP addresses of its default gateway and the remote host. However, in order to properly construct a frame, the PC needs an appropriate destination MAC address. What MAC address does the PC need to learn, and what protocol will the PC use to learn that MAC address?

Network Layer - Computer Networks - Tanenbaum
The question states - An IP datagram using Strict source routing option has to be fragmented. Do you think the option is copied into each fragment, or is it sufficient to just put it in the first fragment? Explain your answer. My thinking ... every fragment. I doubt this reasoning and don't see any flaws in my own answer. Where is my answer lacking?
