Which of the following statements about the default status of switches is accurate?

• A. All switches run in the same region by default.
• B. The STP calculation speed is slower with multiple instances configured.
• C. All switches switch to RSTP if there are no configurations.
• D. Each switch runs in an independent region.

Answer: (D)

The statement indicating that each switch runs in an independent region when there are no configurations is accurate because, by default, switches operate in their own context until explicitly configured otherwise. In a switched network, the Spanning Tree Protocol (STP) is responsible for preventing loops by designating a single root bridge and subsequently forming a loop-free topology. However, each switch initially operates independently and does not share configurations or settings unless they are specifically set to do so by network design. This independence ensures that any configuration related to spanning trees, regions, and general settings must be managed individually, allowing for flexibility and customization of network behavior on a per-switch basis. Therefore, the notion that each switch begins without any pre-set relationship or configuration, leading them to operate in isolation, aligns with standard network design principles. The other statements present different perspectives that do not accurately reflect the default behavior of switches. For instance, while switches may or may not run in the same region based on their configuration, the default is that they are independent unless changes are made. The STP (Spanning Tree Protocol) calculation speed is not inherently slower when multiple instances are configured; rather, it depends on several factors including the complexity of the topology. Lastly, RSTP (Rapid
