A business-critical application deployed on App Engine Flexible environment experiences high latency during peak hours. You've been tasked with optimizing the application. Which of the following App Engine capabilities would you leverage to minimize latency? (Select 2)

*Explanation:* A. Correct. Adjusting the instance class to provide more CPU and RAM resources can improve performance and reduce latency. B. Task Queues are not supported in App Engine Flexible, so it's incorrect. C. NEGs are not designed to minimize latency within App Engine, so it's also incorrect. D) Using Cloud CDN to cache static content can reduce latency and is correct. E) Deploying the application in additional regions might reduce latency for users closer to those regions but doesn't directly address optimizing latency within the existing region.
