Which OSI layer header contains the address of a destination host that is on another network?
A . application
B . session
C . transport
D . network
E . data link
F . physical

Answer: D

Explanation:

Only network address contains this information. To transmit the packets the sender uses network address and datalink address. But the layer 2 address represents just the address of the next hop device on the way to the sender. It is changed on each hop. Network address remains the same.
