Designing Cisco Network Service Architectures (ARCH, legacy) — Question 87

Which technology guarantees loop free network and does not contain the state "listening"?

Answer options

• A. RPVST+
• B. STP
• C. VSS

Correct answer: A

Explanation

RPVST+ (Rapid Per-VLAN Spanning Tree Plus) is designed to provide a loop-free network without the 'listening' state, enabling faster convergence. STP (Spanning Tree Protocol) includes a 'listening' state as part of its process, which can lead to slower convergence times. VSS (Virtual Switching System) is a Cisco technology that combines multiple switches but does not specifically address loop-free networking in the same context as RPVST+.
