Which command enables the Rapid Spanning Tree Protocol?

(config)#spanning-tree mode rapid-pvst
(config)#spanning-tree rapid-pvst mode
(config)#enable rapid-stp
(config)#spanning-tree rapid-pvst enable

The correct answer is: (config)#spanning-tree mode rapid-pvst

The command that enables the Rapid Spanning Tree Protocol (RSTP) is correctly identified as spanning-tree mode rapid-pvst. This command sets the spanning tree protocol to use Rapid Per VLAN Spanning Tree (Rapid PVST), which is a Cisco implementation of RSTP that allows for rapid convergence and minimizes network downtime during topology changes. When this command is executed in the global configuration mode of a Cisco switch, it allows the switch to use RSTP for each VLAN individually, improving network efficiency and performance. RSTP provides faster convergence compared to the original Spanning Tree Protocol (STP), making it essential for modern network designs that require rapid recovery from link failures. The importance of this command lies in its ability to optimize the behavior of the spanning tree process, allowing switches to quickly reconfigure their port states and minimize loops. While other commands might seem relevant, they do not follow the correct syntax or do not represent the functionality needed to enable Rapid PVST.
