In what environment are untested code changes typically isolated to prevent disruptions?

The correct answer is a sandbox environment. A sandbox is designed specifically to test new code changes and isolate them from the production environment, where live applications and data reside. By using a sandbox, developers can ensure that the changes do not negatively impact ongoing operations or existing systems. This isolation allows for thorough testing and experimentation without the risk of causing harm to the production environment.

In a sandbox, developers can check for bugs, performance issues, and compatibility problems, ultimately leading to a more stable and reliable product when the code is eventually moved to production. This dedicated space for untested code ensures that any potential disruptions resulting from new updates are contained within the sandbox, allowing teams to confidently assess the code's functionality before rollout.

Other environments, such as production, testing, and development, serve different purposes. The production environment is where the actual applications run and users interact with them, making it unsuitable for untested changes. The testing environment might be used for some preliminary evaluations of code, but it typically reflects a standardized setup mimicking production, rather than isolating new changes. The development environment is where code is created and originally modified, but it may not be adequately controlled to prevent code changes from impacting production systems. Therefore, the sandbox is the ideal choice for isol
