CompTIA A+ Core 2 (220-1202) — Question 141

A user's application only works with a legacy version of the OS. The OS is reaching its end of life date. For security reasons, the company is migrating to the current version of the OS. Which of the following is the most efficient way to complete the migration while maintaining accessibility to the application?

Answer options

• A. Terminal server
• B. Bare-metal server
• C. Multiboot
• D. Virtualization

Correct answer: D

Explanation

The correct answer is D, Virtualization, as it allows the legacy application to run on a virtual machine with the old OS while the main system operates on the new OS. Options A and B do not provide the necessary support for running legacy software alongside the new OS, and C, Multiboot, would require rebooting to switch between OS versions, making it less efficient for accessibility.
