Question 1
-
A Data Engineering Consultant is working on optimizing the CI/CD pipeline for a data processing application on AWS. The application's CI/CD pipeline utilizes AWS CodeBuild for its build and test processes. One of the requirements is to reduce build times and resource consumption. The application has conditional build scenarios, where certain builds require more compute resources than others based on the complexity and size of the data being processed.
Which feature of AWS CodeBuild should the consultant configure to optimize the build process while considering varying resource needs for different builds?
Answer: A

Question 5
-
In a recent project, a Cloud Data Engineering Consultant is tasked with enhancing the security posture of an organization's cloud-based data processing application. The application, hosted on AWS, interacts with several databases and external APIs, requiring different credentials and API keys for access. A crucial requirement is that these credentials should be securely managed and regularly rotated to minimize security risks. At present, these sensitive credentials are embedded directly in the application code and configuration files, leading to a substantial security vulnerability.
The consultant must develop a secure, scalable, and efficient strategy to handle and periodically rotate these secrets. Which solution should the consultant recommend?
Answer: D
