Which configuration ensures that the switch is always the root for VLAN 750?

A. Switch(config)#spanning-tree vlan 750 priority 38003685
B. Switch(config)#spanning-tree vlan 750 root primary
C. Switch(config)#spanning-tree vlan 750 priority 614440
D. Switch(config)#spanning-tree vlan 750 priority 0

Correct Answer: D

Explanation/Reference:
Although the spanning-tree vlan 10 root primary command will ensure a switch will have a bridge
priority value lower than other bridges introduced to the network, the spanning-tree vlan 10
priority 0 command ensures the bridge priority takes precedence over all other priorities.
