I'll go with D as ABC looks too much work or irrelevant. Although not sure how AFQ actually achieves the read without impacting performance.

Selected Answer: D
Not A - Pipe Resolvers require coding, would not consider that 'operationally efficient' Not B - CloudFront caches web content at the edge, not DynamoDB query results for apps Not C - Neither API Gateway or Lambda have anything to do with DynamoDB performance D - Can do exactly that

For an operationally efficient solution that minimizes impact on baseline performance in a microservice-based serverless web application retrieving data from multiple DynamoDB tables, Amazon CloudFront with Lambda@Edge functions (Option B) is often the most suitable choice

The Answer is A. Some use case for AWS AppSync is Unified data access. Consolidate data from multiple databases, APIs, and microservices in a single network call, from a single endpoint, abstracting backend complexity. https://aws.amazon.com/pm/appsync/?trk=e37f908f-322e-4ebc-9def-9eafa78141b8&sc_channel=ps&ef_id=Cj0KCQjwmvSoBhDOARIsAK6aV7jtg2I6jyXBH6_uUOKRrRoLmXQxaGbwYBP0aO1-RmauWW55DuXSGTMaAnT9EALw_wcB:G:s&s_kwcid=AL!4422!3!647301987556!e!!g!!aws%20appsync!19613610159!148358960849

Selected Answer: B
B - seems more operationally efficient A: example to make use of GraphQL with multi DynamoDB tables https://www.youtube.com/watch?v=HSDKN43Vx7U but it seems not the most operationally efficient to set it up D: it can be useful when needs to join multi DynamoDB tables But also "querying DynamoDB using Athena can be slower and more expensive than querying directly using DynamoDB" refer to https://medium.com/@saswat.sahoo.1988/combine-the-simplicity-of-sql-with-the-power-of-nosql-pt-2-cff1c524297e

Selected Answer: D
I like D) the most. D. Amazon Athena Federated Query with a DynamoDB connector. I don't like A) since this is not a GraphQL query. I don't like B). Since Query multiple tables in DynamoDB from Lambda may not be efficient.
