What is a correct statement about Spanning Tree Protocol (STP)?

The Spanning Tree Protocol (STP) is a network protocol that is essential for preventing loops in Ethernet networks by creating a loop-free logical topology. Adjusting link costs is a critical feature of STP. By modifying the path cost values associated with different links, network administrators can influence the decision-making process when the protocol determines the most efficient path for data to travel. This capability allows for a more optimized use of network resources and can improve performance by directing traffic through faster or more reliable links while avoiding congested paths.

This feature of adjusting link costs is significant in scenarios where a network has multiple paths between devices. The effectiveness of STP in maintaining optimal network performance highlights the ability to configure link metrics to prioritize specific routes, which can lead to better bandwidth utilization and overall efficiency in the network.

Other statements, while they do relate to aspects of STP, do not hold the same level of relevance or correctness. For example, while STP does operate with default configurations, some network environments may require specific configurations for optimal performance. Similarly, STP convergence is not instantaneous; it can take several seconds depending on the network size and the topology, which is crucial for understanding its operational dynamics. Lastly, disabling STP is typically not preferred as it
