Cisco Certified Network Associate (CCNA) Practice Exam

What range and increment can the STP bridge priority be configured to?

1. Range: 0 - 32,768, Increment: 2,048

2. Range: 0 - 61,440, Increment: 4,096

3. Range: 1 - 50,000, Increment: 5,000

4. Range: 0 - 128,000, Increment: 8,192

The correct answer is: Range: 0 - 61,440, Increment: 4,096

The correct answer is that the Spanning Tree Protocol (STP) bridge priority can be configured with a range of 0 to 61,440, and the increment is 4,096. This is important in the context of managing STP in a network. The bridge priority is a value that helps determine how the root bridge is elected in a spanning tree topology. The lower the bridge priority, the higher the preference it has to become the root bridge. The specified increments allow network administrators to set priorities at certain intervals while maintaining flexibility in configuring the network according to its needs. Understanding the range and increment is crucial because it impacts how the network path is determined, especially in larger and more complex network topologies. When network engineers adjust the bridge priority, they are essentially influencing STP's behavior for better traffic management and reduced loops in the network. The other ranges provided do not align with the established standards for STP bridge priority, which is why they are not correct. Being precise about these parameters ensures effective network design and troubleshooting, which is a core aspect of the skills assessed in the CCNA certification.
