Answer: Adopting continuous integration and continuous deployment (CI/CD) practices, Implementing manual review processes for all changes

**Correct Options: D. Adopting continuous integration and continuous deployment (CI/CD) practices and A. Implementing manual review processes for all changes** **Explanation:** CI/CD practices are essential for automating the testing and deployment of updates to data pipelines, ensuring reliability through automated testing, frequent deployments, and the ability to rollback changes if necessary. Manual review processes complement CI/CD by adding an additional layer of scrutiny for critical changes, further enhancing reliability. **Why other options are incorrect:** - **B. Utilizing larger datasets for processing to test pipeline robustness:** While testing with larger datasets can identify performance issues, it does not inherently ensure the reliability of updates without comprehensive testing and deployment strategies. - **C. Disabling logging to reduce overhead during updates:** Logging is crucial for troubleshooting and debugging; disabling it can make identifying and resolving issues more difficult. - **E. Reducing the number of pipeline nodes to simplify the architecture:** Simplifying the architecture may reduce complexity but does not directly contribute to the reliability of updates without proper testing and deployment practices.
