How do you configure STP on the switch in the Cisco FabricPath domain on VLAN 10?

You configure STP on a switch that is attached to a Cisco FabricPath domain and that has the vPC feature deployed.

How do you configure STP on the switch in the Cisco FabricPath domain on VLAN 10?
A . switch(config)# spanning-tree vlan 10 priority 0
switch(config)# spanning-tree pseudo-information
switch(config-pseudo)# vlan 10 root priority 0
B . switch(config)# spanning-tree vlan 10 priority 8192
switch(config)# spanning-tree pseudo-information
switch(config-pseudo)# vlan 10 root priority 4096
C . switch(config)# spanning-tree vlan 10 priority 4096
switch(config)# spanning-tree pseudo-information
switch(config-pseudo)# vlan 10 root priority 8192
D . switch(config)# spanning-tree vlan 10 priority 0
switch(config)# spanning-tree pseudo-information
switch(config-pseudo)# vlan 10 root priority 4096

Answer: B

Explanation:

Note that it is fine to use the spanning-tree priority command and the spanning-tree pseudo-information command together, but the root priority in the pseudo-information needs to be a lower value (higher priority) than the spanning-tree priority to make sure that the remaining working Cisco FabricPath switch is sending a superior BPDU with the common FabricPath bridge ID and the configured spanning-tree pseudo-information priority and remains at the spanning-tree root.
