What is the general term for a group of routers functioning as a single logical router?

1. Router group

2. Virtual router

3. Logical router

4. Router cluster

The correct answer is: Virtual router

A virtual router is indeed the correct term for a group of routers that work together to present themselves as a single logical router to the network. This configuration allows multiple physical routers to share information and resources, enhancing both redundancy and load balancing. By presenting a unified interface to the outside world, virtual routers enable more efficient traffic management and routing capabilities. Using virtual routers can significantly streamline network management and integration, especially in environments where high availability and resilience are critical requirements. Other choices might refer to concepts related to routing, but they do not accurately capture the idea of a group of routers operating together as a single logical entity. The terms "router group," "logical router," and "router cluster" can suggest similar functionalities but do not specifically denote the same concept as a virtual router in common networking terminology.
