In what situation is the use of a routed network layout most beneficial?

The use of a routed network layout is most beneficial in scenarios where minimizing latency is critical. This is because a routed network can intelligently direct data traffic and effectively manage how information is transmitted across the network. Routing allows for different paths to be taken, optimizing the flow of data and ensuring that it reaches its destination quickly.

In environments where real-time video surveillance or monitoring is essential, such as in security systems, reducing latency can significantly enhance the system's effectiveness. Properly configured routed networks can prioritize video data over less time-sensitive information, ensuring that surveillance feeds are transferred without delay, which is critical in reacting swiftly to incidents.

In contrast, installations that only require coverage of a small area may not necessitate the complexities of a routed network, and using analog cameras does not require the network benefits associated with digital systems. Additionally, while multiple connections could benefit from the flexibility of a routed network, the primary focus in this scenario is on minimizing latency, making it the best choice.
