Which OSI layer header contains the address of a destination host that is on another network?

A. Application
B. Presentation
C. Session
D. Transport
E. Network
F. Data link
G. Physical

Answer: E

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.
