As part of a nightly testing process, new version of an application is deployed to the set of web servers in the development environment. Which of the following is the BEST way to ensure the test…

Cloning servers might work initially but doesn't guarantee a clean state daily as changes could accumulate, and it's resource-intensive for nightly refreshes.

Reprovisioning from predefined templates is effective but often more drastic than simply reverting state; configuration management can correct drift on existing servers more efficiently.

Simply undeploying and deploying new application versions does not address potential configuration drift or environmental changes on the web servers themselves, only the application binary.

Reverting the environment to a previous known good state using configuration management tools ensures that each night's test starts from an identical baseline. This practice eliminates configuration drift and ensures reliable, consistent test results by enforcing the desired configuration.
