In which scenario would a star topology be less favorable?

A star topology might be less favorable when cost is a significant concern because it typically requires more cabling and network devices, specifically a central hub or switch. The configuration necessitates a cable from each device to the central point, which can drive up costs, especially in larger networks with many devices.

In contrast, other scenarios might favor a star topology due to its benefits. For instance, easy troubleshooting is facilitated in a star topology since any failure in a single cable or device does not affect the entire network, allowing for quick identification and resolution of problems. When many devices need to be connected, although the star topology can become costly, it also allows for effective management and communication. Lastly, if user isolation is required, star topology can effectively segment traffic and maintain privacy since each connection is independent, making it easier to control data flow between devices seamlessly.

Thus, when taking cost into account, the star topology may not be the most economical choice compared to other configurations like bus or ring topologies.
