CompTIA A+ 220-1101 Practice Question

Application virtualization allows an application to run on multiple operating systems without modifying the host system by creating virtual environments. This method ensures compatibility and facilitates testing across various OS setups. Sandboxing is primarily used for security purposes, such as testing untrusted code, and may not be suitable for diverse OS compatibility. Using separate physical machines for each OS increases costs and decreases efficiency. Developing on the primary environment without proper cross-OS testing risks compatibility issues.
