Question

Which spanning-tree standard supports only one root bridge so that traffic from all VLANs flows over the same path?

A) Rapid PVST
B) 802.1D
C) MST
D) PVST+

Answer 1

The 802.1D standard, also known as STP (Spanning Tree Protocol), supports only one root bridge so that traffic from all VLANs flows over the same path, optimizing network efficiency and avoiding loops.

Step-by-step explanation:

The spanning-tree standard that supports only one root bridge so that traffic from all VLANs flows over the same path is 802.1D, also known as STP (Spanning Tree Protocol). The STP is a network protocol that creates a loop-free logical topology for Ethernet networks.

STP ensures that there is only one path of communication between any two network devices, preventing network loops. It elects a designated root bridge and determines the shortest path from each network device to this root bridge.

By having a single root bridge, all VLAN traffic is directed through a common path, optimizing network efficiency and avoiding unnecessary loops.
