Which scenario best describes a function of a virtual router?

A virtual router primarily functions to connect multiple networks and route traffic between them. This capability allows the virtual router to manage and direct data packets from one network to another, facilitating communication and resource sharing across distinct subnets or networks.

In contrast, directing data traffic on a local network is typically the role of a switch or a traditional router, which operates primarily at Layer 2 (Data Link Layer) for local network traffic management. Providing internet access to a single device usually involves a direct connection to a modem or a physical router. Finally, switching data between local devices is a function primarily associated with switches, which connect devices within the same local area network (LAN) rather than handling inter-network traffic routing.

Thus, the best representation of a virtual router's capabilities is its ability to connect multiple networks and manage routing traffic effectively between those networks.
