Isabella configures three virtual machines, VM1, VM2, and VM3, on a Windows Server 2019 host. The host and VM1 are connected to a physical switch (external virtual switch). VM1 and VM2 are connected to a private virtual switch. VM2 and the host are connected to an internal virtual switch. VM3 is not connected to any switch. Isabella is building an application that provides clients access to confidential financial information in a secure database. Isabella chooses to run the application on the host server and decides to implement an N-tier security design to protect the database. Where should Isabella place the database?

On VM2 VM2 is the best choice to place the database because VM2 and the host are connected to an internal virtual switch. Any users trying to access the database in VM2 can only do so through the application running on the host. This type of data security design is called N-tier, as it requires that users pass through a number of systems (N) that implement security measures before gaining access to sensitive data.
