To isolate a VM from the rest of the servers, which configuration should the administrator apply?

• A. Virtual NIC
• B. Trunk port
• C. Virtual memory
• D. VPN connection

Answer: (A)

To isolate a VM from the rest of the servers, control over its network path is key. The VM’s network interface, the virtual NIC, defines how it connects to the network. By configuring that vNIC to attach to a dedicated, isolated virtual switch or a separate VLAN, the VM’s traffic stays within that isolated segment and cannot reach other servers. This is how isolation is achieved at the virtual network layer. A trunk port is a switch-side setting that carries multiple VLANs between devices; while it affects how networks are carried, it doesn’t by itself isolate a single VM. Virtual memory deals with RAM handling, not networking. A VPN connection provides secure remote access to a network, not isolation from internal servers.
