Your network contains a Hyper-V host named Host1 that runs Windows Server 2008 R2. The host is connected to VLAN ID 10. For testing purposes， you plan to deploy several virtual machines （VMs） on the Host1. You need to recommend which virtual networks must be created for the VMs. The solution must ensure that the VMs can only connect to other VMs. Which network configuration or configurations should you recommend？（）

• A、an external network on VLAN ID 10
• B、an internal network on VLAN ID 11
• C、an external network on VLAN ID 11
• D、a private network on VLAN ID 10
• E、an internal network on VLAN ID 10
