Show answer and explanation
Correct answers: A, E
Explanation
To ensure a smooth rollout of a new Cloud Run application version, it's important to use traffic splitting to gradually test the new version with real traffic. This minimizes risk and helps identify issues early. Creating a new revision with specific configurations for testing is also a best practice, allowing for separation of concerns and easier management of different revisions.
- A. Correct.
Using traffic splitting allows you to gradually direct traffic to the new version, which helps in identifying and resolving issues before a full rollout.
- B. Incorrect.
Deploying the new version as a separate service may complicate traffic management and doesn't utilize Cloud Run's built-in traffic management features.
- C. Incorrect.
Directing 100% of the traffic to the new version without testing can lead to service disruptions if the new version has issues.
- D. Incorrect.
Manually testing in the Cloud Run console without directing any traffic doesn't provide real-world traffic conditions for testing.
- E. Correct.
Creating a new revision allows you to configure environment variables specific to testing and helps in managing different versions efficiently.
