- A
Development environment for individual feature testing
- B
Integration environment for testing how components work together
- C
Staging environment that mirrors production for validation
- D
A dedicated environment for end-users to perform live testing before production deployment
- E
A backup environment for disaster recovery
Show answer and explanation
Correct answers: A, B, C
Explanation
To ensure proper testing, validation, and stability, a standard setup includes development, integration, and staging environments. These environments allow for isolated development, component integration testing, and pre-production validation, respectively. While disaster recovery and user testing environments can be useful in specific scenarios, they are not mandatory for a typical DevOps pipeline.
- A. Correct.
A development environment is crucial for individual developers or teams to test their changes in isolation without affecting shared environments.
- B. Correct.
An integration environment is necessary to test how different components or services interact with each other, ensuring compatibility and avoiding unexpected issues.
- C. Correct.
A staging environment is a critical step to simulate production-like conditions and validate the application's performance and functionality before deployment.
- D. Incorrect.
A dedicated environment for end-users to perform live testing is typically not required in standard setups as user acceptance testing is often done in staging or other controlled environments.
- E. Incorrect.
A backup environment is used for disaster recovery but is not directly related to validating the application's functionality during development or deployment.
