In which scenario would a router be used in a network?

• A. To connect multiple devices within a LAN
• B. To manage traffic within a VLAN
• C. To route data between different networks
• D. To switch packets between devices

Answer: (C)

A router is specifically designed to route data between different networks, making it an essential device in network communications that spans multiple subnets or different networks altogether. It performs the critical function of directing data packets based on their destination IP addresses, ensuring that they take the most efficient path toward their target network. This capability is fundamental for facilitating communication across diverse network segments, such as connecting a local area network (LAN) to the internet or linking various remote locations. In the context of the other scenarios: connecting multiple devices within a LAN is typically managed by a switch, which operates at Layer 2 of the OSI model. Managing traffic within a VLAN is also a responsibility of networking devices such as switches or layer 3 switches that can handle routing between VLANs, rather than a traditional router. Lastly, switching packets between devices focuses on the operations performed within a single network, which again is primarily a switch’s function. Therefore, the role of a router is specifically aligned with the task of facilitating communication between distinct networks, solidifying answer C as the correct choice.
