Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
What are two functions that are provided by the network layer? (Choose two.)
A
carrying data between processes that are running on source and destination hosts
B
providing end devices with a unique network identifier
C
placing data on the network medium
D
directing data packets to destination hosts on other networks
E
providing dedicated end-to-end connections
Explanation: 

Detailed explanation-1: -Option 1 and 5-The network layer is responsible for transferring data packets from the host device to the destination device running on another network. Also, it is responsible for providing unique identifiers to the end devices.

Detailed explanation-2: -The primary function of the network layer is to enable different networks to be interconnected. It does this by forwarding packets to network routers, which rely on algorithms to determine the best paths for the data to travel.

Detailed explanation-3: -Forwarding has two main operations: match and action. With destination-based forwarding, the match operation of a router looks up only the destination IP address of the to-be-forwarded datagram, and the action operation of the router involves sending the packet into the switching fabric to a specified output port.
