In the following pairs of OSI protocol layer/sub-layer and its functionality, the INCORRECT pair is

1. Network layer and Routing
2. Data Link Layer and Bit synchronization
3. Transport layer and End-to-end process communication
4. Medium Access Control sub-layer and Channel sharing

Correct answer: Data Link Layer and Bit synchronization

Solution

The Data Link Layer primarily focuses on node-to-node data transfer and error detection, while bit synchronization is more closely associated with the Physical Layer, which handles the transmission of raw bit streams over a physical medium.
