Explanation / Answer

Q 10) What field always changes when an IP datagram is forwarded by a NAT router?

Source IP address

This is because when the IP datagram is forwarded by a NAT router, the Source IP Address field in the IP header changes according to the datagram when it's forwarded to its ultimate destination. The IP address is changes to the new source address of the IP packet so that it appears that the packet originated from the Routing Device itself.
