Which of the following is NOT a function of a switch?

A switch primarily operates at the Data Link layer (Layer 2) of the OSI model and is designed to connect devices within the same network, facilitating communication between them. It efficiently manages data traffic by directing data packets to their intended devices based on MAC addresses, reducing collisions and increasing overall network performance. Additionally, by providing multiple ports, a switch increases the number of devices that can connect to a network, enhancing network versatility and connectivity.

In contrast, routing packets between different networks is a function specific to routers, which operate at the Network layer (Layer 3) of the OSI model. Routers determine the best path for data packets to reach their destination across various networks, which is outside the scope of a switch's functionality. Therefore, the choice that indicates routing packets between different networks is the correct response to the question regarding the functions of a switch.
