An organization wants to create a server VM that is segregated from the rest of the servers. Which of the following should the server administrator configure?

A Virtual NIC (vNIC) connects a VM to the virtual network infrastructure, allowing it to be placed on a specific virtual switch, subnet, or VLAN. By configuring the vNIC to be on a separate virtual network segment or VLAN, the VM can be logically isolated from other servers, preventing direct communication and enforcing network segregation.

A trunk port is configured on a physical switch or hypervisor's physical network adapter to carry traffic for multiple VLANs, not directly on a VM to segregate it.

Virtual memory refers to the memory resources allocated to the VM and has no bearing on its network segregation.

A VPN connection is typically used for secure remote access or connecting networks over an insecure medium, not for basic network segregation of a VM within its local hypervisor environment.
