Show answer & explanation
Correct answer: A
Correct matching and explanation:
Data Link Layer → Piggybacking. Piggybacking is used to combine data frames and acknowledgements to improve efficiency, a technique implemented at the data link layer.
Network Layer → Produce billing information. The network layer handles routing, addressing and can collect usage/accounting information used for billing or charging.
Transport Layer → True end-to-end layer. The transport layer provides end-to-end communication services (reliability, flow control) between hosts, making it the true end-to-end layer.
Session Layer → Token Management. The session layer manages dialogues and controls (such as token management) to coordinate which peer may transmit.
Therefore the correct mapping is: Data Link Layer → Piggybacking; Network Layer → Produce billing information; Transport Layer → True end-to-end layer; Session Layer → Token Management.
