The switched LAN is displayed below:

In this network, STP has been implemented. Switch SW1 is the root switch for the default VLAN.To reduce the broadcast domain, the network administrator decides to split users on the networkinto VLAN 2 and VLAN 10. The administrator issues the command spanning-tree vlan 2 rootprimary on switch SW1. What will happen as a result of this change?()

A.Switch SW1 will change its spanning tree priority to become root for VLAN 2 only
B.All ports of the root switch SW1 will remain in forwarding mode throughout the reconvergenceof the spanning tree domain
C.No other switch in the network will be able to become root as long as switch SW1 is up andrunning
D.Switch SW1 will remain root for the default VLAN and will become root for VLAN 2
E.None of the other alternatives apply
