Refer to the exhibit. The Layer 2 network uses VTP to manage its VLAN database. A network designer created all VLANs on the VTP server （switch 1） and it has been advertised through VTP to all other VTP clients （switches 2 through 4）. Due to network growth， a network operator decided to add a new switch between switch 1 and switch 3. The network operator has been instructed to use a refurbished switch and use a VTP client. Which three of these factors should the network operator consider to minimize the impact of adding a new switch？（）
A. Pay special attention to the VTP revision number， because the higher value takes the priority.
B. Configure all VLANs manually on the new switch in order to avoid connectivity issues.
C. A trunk should be established between the new switch and switches 1 and 3 as VTP only runs over trunk links.
D. Set at least the VTP domain name and password to get the new switch synchronized.
E. An ISL trunk should be established between the new switch and switches 1 and 3， because VTP only runs over ISL.
F. Pay special attention to the VTP revision number， because the lower value takes the priority.
