  3. Error recovery
  4. Routing

Questions & Step-by-Step Solutions

Which of the following is NOT a function of the Network Layer?
  • Step 1: Understand what the Network Layer does. The Network Layer is responsible for routing data from one device to another across different networks.
  • Step 2: Identify the main functions of the Network Layer. These include packet forwarding, addressing, and routing.
  • Step 3: Learn about the Transport Layer. The Transport Layer is responsible for ensuring reliable data transfer, error recovery, and flow control.
  • Step 4: Compare the functions of both layers. Since error recovery is a function of the Transport Layer, it is NOT a function of the Network Layer.
  • Step 5: Conclude that the correct answer to the question is error recovery, as it is handled by the Transport Layer.
