Correct Answer: A,C,D
A 5-stack instance structure (dev, QA, UAT, staging, production) provides several advantages: A: Staging instance for troubleshooting: The staging instance closely mirrors the production environment, allowing for thorough testing and troubleshooting of changes before they are deployed to production. C: Deployment testing: Each instance serves a specific testing purpose (QA for functional testing, UAT for user acceptance testing), ensuring comprehensive validation before production deployment. D: Increased parallel activity: Different teams can work simultaneously in their respective instances, increasing development and testing efficiency. Why not the other options? B: Lower maintenance effort: A 5-stack structure can actually increase maintenance effort due to the need to manage multiple instances. E: Single Dev track: A 5-stack structure typically supports multiple development tracks or branches.
