You have a network configured with three VLANs of users. You want to make sure that the switches connected to the servers for the Sales and Production workgroups become the respective root bridges. Which series of commands would you need to enter? Refer to the following exhibit.

A.	SwitchB(config)#spanning-tree vlan 2 priority 16384
	SwitchB(config)#spanning-tree vlan 7 priority 16384
B.	SwitchA(config)#spanning-tree vlan 2 priority 16384
	SwitchC(config)#spanning-tree vlan 7 priority 16384
C.	SwitchA(config)#spanning-tree vlan 7 priority 16384
	SwitchC(config)#spanning-tree vlan 2 priority 16384
D.	SwitchA(config)#spanning-tree vlan 2 priority 16384
	SwitchC(config)#spanning-tree vlan 5 priority 16384

B. The first switch you must configure as a root bridge is Switch A for VLAN 2 with a priority of 16,384. Then configure Switch C as a root bridge for VLAN 7 with a priority of 16,384.
