Show answer and explanation
Correct answers: A, B, C, F
Explanation
To ensure a smooth development lifecycle, at least four distinct environments are typically needed: a development environment for coding and initial testing, a QA environment for thorough testing, a staging environment to replicate production for final validation, and a production environment for serving end users. Each environment serves a specific purpose to minimize risks, detect issues early, and ensure a stable deployment process.
- A. Correct.
The development environment is critical for writing and testing code in an isolated and iterative manner. It allows developers to test their changes without affecting other environments.
- B. Correct.
A QA environment is used for both automated and manual testing to ensure that the application behaves as expected before being promoted to staging or production.
- C. Correct.
The staging environment is designed to closely replicate the production environment and is used to test final builds and configurations before release to production.
- D. Incorrect.
The production environment is not intended for internal testing. It is meant for serving end users with a stable and reliable version of the application.
- E. Incorrect.
A disaster recovery environment is not used for deploying experimental features. It is usually a backup environment planned for restoring the system in case of failure.
- F. Correct.
The production environment is the final destination for stable application releases and is designed to serve end users with minimal downtime.
