Example answers and how they were marked
Full marks1/1
The destination IP address.
Why: Names the destination IP address (1).
No marks0/1
The domain name.
Why: A domain name is not used by a router to route a packet; it must be translated to an IP address first, so no mark.
No marks0/1
The MAC address.
Why: A MAC address is not used to route packets across the internet; the Do not accept line applies.
