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.
