A development team is struggling with environment inconsistencies: an application works on a developer's laptop but fails in the test environment due to different library versions and system configurations. They want to ensure that the application runs identically across all environments. Which solution should they implement?

Use a configuration management tool to manually adjust each environment.

Package the application and its dependencies into a container image that is used in every environment.

Create a detailed setup document for each environment.

Use Infrastructure as Code to provision identical virtual machines.

What is a common strategy for rolling back a failed release?

Recompiling the source code from scratch.

Redeploying the previous known-good version of the application.

Deleting all logs and restarting the server.

Ignoring the failure and continuing with the release.
