| B. |
reduces the CPU cycles for all the switches in the network. | |
| C. |
allows the root switch location to be optimized per VLAN. | |
| D. |
automatically selects the root bridge location, to provide optimized bandwidth usage. |
Per VLAN Spanning Tree (PVST) maintains a spanning tree instance for each VLAN configured in the network. This means a switch can be the root bridge of a VLAN while another switch can be the root bridge of other VLANs in a common topology.
