Answer: Amazon DocumentDB, Amazon DynamoDB

The correct answers are D (Amazon DocumentDB) and E (Amazon DynamoDB). Both of these services are NoSQL databases provided by AWS. Amazon DocumentDB is a fully managed document database that is compatible with MongoDB, offering high performance and durability for NoSQL workloads. Amazon DynamoDB is a fully managed NoSQL database service known for its fast and predictable performance at any scale, with low-latency data access and automatic scaling capabilities. Options A (Amazon Aurora), B (Amazon RDS), and C (Amazon Redshift) are not correct as they are either relational databases or a data warehousing solution, which do not fit the requirement for a NoSQL database.
