A.Because the configuration revision of the new switches is lower than the rest of the network， it can change the VLAN database of the other switches.
B.As a VTP server， the new switch deleted all VLANs of the network.
C.Erasing VLANs increases the VTP configuration revision.
D.Since the configuration revision of the network is higher than the new switch， the VLAN database was automatically synchronized.
