What is a key benefit of using MST?

Using Multiple Spanning Tree (MST) is advantageous because it consolidates the number of spanning-tree instances, allowing for more efficient network management. Each VLAN can be mapped to a specific spanning tree instance, which enables the optimization of bandwidth and load balancing across links. By reducing the number of spanning tree instances required, MST minimizes the overhead associated with managing multiple instances, leading to improved performance and easier configuration.

This simplification helps network administrators manage the network more effectively, as they need to monitor fewer instances while maintaining the necessary protections against loops. The capability of mapping VLANs to instances also means that traffic can be managed more consistently, optimizing the use of available network resources and enhancing overall efficiency.

While other options might suggest drawbacks or complications, the primary strength of using MST is its ability to streamline spanning tree management, ultimately leading to a more robust and manageable network design.
