A company relies on a critical legacy application that does not run on current operating systems. The IT department needs to keep this application available without maintaining outdated physical hardware. Which of the following is the BEST solution?
Use the operating system's compatibility mode features
Create a virtual machine with the legacy operating system the application requires
Partition the hard drive to install the legacy operating system alongside the current one
Upgrade the legacy application so it is compatible with current operating systems
Creating a virtual machine that hosts the legacy operating system provides an isolated environment in which the application can run on modern hardware. The VM encapsulates the older OS and software, avoiding compatibility problems on the host and eliminating the need to preserve obsolete equipment. Upgrading the application may not be possible if the vendor no longer supports it, dual-booting still ties the system to an old OS installation, and compatibility mode often fails with complex legacy applications.
