JNCIP-ENT: Juniper Networks Certified Professional – Enterprise Routing (2023) — Question 51

You are implementing a single spanning tree instance in your network and want to use the protocol that will give you the best convergence time in the event of a physical network failure of the root bridge.
Which spanning tree protocol will satisfy this requirement?

Answer options

• A. RSTP
• B. STP
• C. MSTP
• D. VSTP

Correct answer: A

Explanation

RSTP (Rapid Spanning Tree Protocol) is designed to provide faster convergence times compared to STP (Spanning Tree Protocol), which is slower due to longer timers. MSTP (Multiple Spanning Tree Protocol) and VSTP (VLAN Spanning Tree Protocol) also do not match RSTP's rapid convergence capabilities, especially in scenarios involving root bridge failures.
