Ruckus Certified Network Integrator (RCNI) — Question 12

Which device will become the root in the Spanning Tree election process?

Answer options

• A. the device with root guard enabled
• B. the device with the highest IP address
• C. the device with the lowest bridge ID
• D. the device with the highest bridge priority value

Correct answer: C

Explanation

The device with the lowest bridge ID becomes the root in the Spanning Tree election process because the bridge ID is a combination of the bridge priority and the MAC address. The other options do not determine the root; root guard only protects the root from being changed, the highest IP address does not influence the election, and a higher bridge priority value can actually lead to a lower likelihood of being elected as root.
