单项选择题Before inserting a new switch in the network， the network administrator checks that the VTP domain name is correct， the VTP mode is set to server， and revision is lower than the switches in the network. The administrator then configures interfaces and trunks， erases existing VLANs， and connects the switch to the network. Following that procedure， there is no connectivity in the network. What is a possible cause of this problem？（）

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.
