  ". A solutions architect needs to solve the problem with minimal changes to the existing web application." ABD all require major changes to the application. A: DynamoDB is NoSQL so big change B: Elasticache is a caching layer which require code change normally significant code change D: Redshift is analytics so not a solution

  . While DynamoDB is a scalable NoSQL database, it requires changes to the application's data model and query patterns. B. ElastiCache is an in-memory data store that can improve query performance, but it is primarily used for caching rather than running complex queries. D. Redshift is a powerful data warehousing solution, but migrating the data and adapting the queries to Redshift's columnar architecture would require significant changes to the application and query logic. Therefore, option C is the most appropriate recommendation as it leverages read replicas in RDS to offload read-only query traffic from the primary database, allowing the business analysts to run their queries without impacting the performance of the web application. It provides a scalable and efficient solution with minimal changes to the existing web application.

  C. Create a read replica of the primary database and have the business analysts run their queries
