Answer 5

Yah, cause MAC lives on a link. So each end has a MAC address.

Answer 6

A transparent bridge breaks that rule. See, that is what the transparent part is about. It forwards full frames with source MAC intact.

Look at the question. It tells you.

Answer 15

There are two types of addresses involved in sending a packet. See, MAC addressing keeps a local link connected from one device to the next. They are the addresses used over a single piece of wire. But the IP address is the sending or receiving machine. For the sender it is the address of that machine, but can be changed by a router that does NAT. This is similarly done for the destination, as in it thinks it is going to that IP, but a router doing NAT could make some changes.

In other words, unless NAT is involved, the IPs are the IPs of the machines at each end of the link. Each packet will have a sender IP and recipient IP. This allows the recipient to reply to the sender.
