The question describes a scenario where a machine learning pipeline is deployed using Vertex AI Pipelines and Cloud Build for CI/CD. The goal is to improve the process for deploying new pipeline implementations while minimizing the risk of production failures. Several options for structuring the CI/CD pipeline are provided.
The correct answer is C. This option emphasizes a robust CI/CD process including automated testing in a pre-production environment before deploying to production. Options A, B, and D have flaws either in automation or in unnecessary steps (rebuilding in option D).
