Which of the following is a function of a switch in a network?

The primary function of a switch in a network is to filter traffic and forward data to specific devices. Switches operate at the Data Link layer (Layer 2) of the OSI model and use MAC addresses to identify devices on the local network. When a switch receives a data frame, it examines the destination MAC address and determines the appropriate port to forward the frame to, ensuring that the data is sent only to the intended recipient instead of broadcasting it to all connected devices. This capability enhances network efficiency, reduces unnecessary traffic, and improves overall performance within a local area network (LAN). In contrast, connecting multiple networks together is a function typically associated with a router, which operates at the Network layer (Layer 3) and manages IP addresses for various networks. Routing data between different subnets also falls under the responsibilities of a router, as it enables communication between distinct networks by determining the most efficient path for data. While some switches can provide limited internet access through features like VLANs or by connecting to routers, this is not their primary role in a network. Thus, the function of filtering traffic and directing it to specific devices accurately represents the essential operation of a network switch.
