  • C is not correct because the link layer sends data over physical hardware using MAC addresses and does not route packets
  • D is not correct because the transport layer sets up the connection between two computers and reassembles the packets

No marks0/1

D 192.168.1.256

Why: Near miss: it has four numbers but 256 is outside the range 0 to 255 (mark scheme line D), so no mark.

No marks0/1

A 192.168.1

Why: It has only three numbers, so it is not a complete IPv4 address (mark scheme line A), so no mark.
