What are two functions that are provided by the network layer? (Choose two.)
- carrying data between processes that are running on source and destination hosts
- directing data packets to destination hosts on other networks
- providing end devices with a unique network identifier
- placing data on the network medium
- providing dedicated end-to-end connections

Explanation: The network layer is primarily concerned with passing data from a source to a destination on another network. IP addresses supply unique identifiers for the source and destination. The network layer provides connectionless, best-effort delivery. Devices rely on higher layers to supply services to processes.
