  • A Provides end-to-end data delivery service for user applications
  • B Handles the routing of the data packets over the network
  • C Manages IP addressing and encryption for data packets
  • D Defines the procedures for interfacing with Ethernet devices
Explanation

The Network Access or Link layer defines how a host interfaces with the local network technology, including Ethernet procedures. It does not provide end-to-end application delivery or perform IP routing.
