Question
Which spanning-tree protocol version allows for faster convergence and multiple spanning-tree instances?
A. STP
B. RSTP
C. MST
D. PVST+
E. BPDU
Answer
C. MST
Explanation
Multiple Spanning Tree (MST) enables faster convergence and allows multiple spanning-tree instances to optimize VLAN paths.
Multiple Spanning Tree Protocol (MST or MSTP) allows a network to create multiple spanning-tree instances, each capable of controlling a unique set of VLANs. This approach optimizes network resources by reducing the number of spanning-tree calculations required, as multiple VLANs can be mapped to a single instance. MST is based on Rapid Spanning Tree Protocol (RSTP), inheriting its fast convergence capabilities. MSTP introduces the concept of regions and instances, enabling different VLANs to follow different paths and improving both efficiency and redundancy in larger networks. This makes MST the protocol that supports both faster convergence and multiple spanning-tree instances.
