Which two statements describe the services provided by the data link layer? (Choose two.)It ensures that application data will be transmitted according to the prioritization.It provides reliable delivery through link establishment and flow control.It manages the access of frames to the network media.It packages various Layer 3 PDUs into a frame format that is compatible with the network interface.It defines the end-to-end delivery addressing scheme.It maintains the path between the source and destination devices during the data transmission.

Which of the followings is the service provided by Data Link Layer?Answer :Provides user services like user login, naming network devices, formatting messages, and e-mails and transfer of filesTransferring datagram from one node to physically adjacent node over a link.  Breaking up segments from source host into network packets, and reassembling the packets on the receiving host.Provide logical communication between app processes running on different hosts.
