B.
SW3(config)#vtp mode transparent
C.
SW2(config)=vtp pruning
D.
SW1 (config >»vtp mode transparent
SW1 (config)#vtp pruning
Explanation: SW3 does not have VLAN 60 so it should not receive traffic for this VLAN (sent from SW2).
Therefore we should configure VTP Pruning on SW3 so that SW2 does not forward VLAN 60 traffic to SW3. Also notice that we need to configure pruning on SW1 (the VTP Server), not SW2.
