What configuration should be made to segregate a server VM from others?

Segregating a server virtual machine (VM) from others primarily involves controlling network access, and a virtual NIC (Network Interface Card) is fundamental in this process. By configuring a virtual NIC for the server VM, you can establish specific network settings that allow for isolation from other VMs. This means you can assign the VM to a separate virtual switch or network segment, ensuring that it does not communicate with other VMs unless specifically allowed.

Using a virtual NIC enables granular control over the network configuration, including setting up different IP ranges, VLANs, or firewall rules that can restrict traffic. This enhances security by preventing unauthorized access and reducing the attack surface. The virtual NIC acts as the point of connection for the VM to the network, allowing you to enforce these separation policies effectively.

In contrast, the other options do not directly address the primary requirement of VM segregation. A trunk port pertains to Ethernet networking and VLAN tagging, which is not specific to managing connections for individual VMs within a hypervisor environment. Virtual memory relates to the resource allocation for the server VM and does not influence network segregation. Lastly, a VPN connection is used to secure communication over the internet; while it enhances security for outgoing connections, it does not provide intrinsic segregation of the VM
