JNCIS-ENT: Juniper Networks Certified Specialist – Enterprise Routing and Switching (2024) — Question 58

What are the three possible port states when using RSTP? (Choose three.)

Answer options

• A. forwarding
• B. learning
• C. discarding
• D. listening
• E. tagging

Correct answer: A, B, C

Explanation

The correct port states for Rapid Spanning Tree Protocol (RSTP) are forwarding, learning, and discarding. The forwarding state allows data to pass through, learning enables the switch to build its MAC address table, and discarding prevents loops by not allowing traffic. The listening state is not used in RSTP, and tagging is not a port state.
