Ruckus Certified Network Integrator (RCNI) — Question 23

The root bridge is connected to another switch over two independent 10Gbe links. Which link will remain in a forwarding state on both sides?

Answer options

• A. the link with the lowest port number on the non-root switch
• B. the link with the lowest port number on the root switch
• C. the link with the highest port number on the root switch
• D. the link with the highest port number on the non-root switch

Correct answer: B

Explanation

The link with the lowest port number on the root switch will remain in a forwarding state because Spanning Tree Protocol (STP) selects the link with the lowest port number to minimize loops and ensure efficient data transmission. The other options are incorrect as they refer to links on the non-root switch or those with the highest port numbers, which would not be prioritized in the forwarding state.
