Suggested answer: C

Explanation:

A network switch typically operates at Layer 2 of the OSI model, which is the Data Link layer. This layer is responsible for node-to-node data transfer---a function that involves handling data frames between physical devices on the same network or link. The switch uses MAC addresses to forward data to the appropriate destination within the network.
