What characterizes an extended star topology?

An extended star topology is characterized by a central node, such as a switch or router, that connects to multiple star topologies. In this arrangement, each individual star configuration has its own central node, and all of these central nodes are connected to a higher-level central point or infrastructure. This structure allows for easier management and expansion of the network, as multiple star networks can be added or integrated into the overall system without significant disruption.

This configuration enhances the network's redundancy and scalability, as changes or failures in one star segment do not affect the others directly. The overall design is more versatile for larger networks, making it a common choice in various installations.
