AWS Certified Cloud Practitioner — Question 554

A company wants to host its relational databases on AWS. The databases have predefined schemas that the company needs to replicate on AWS.

Which AWS services could the company use for the databases? (Choose two.)

Answer options

• A. Amazon Aurora
• B. Amazon RDS
• C. Amazon DocumentDB (with MongoDB compatibility)
• D. Amazon Neptune
• E. Amazon DynamoDB

Correct answer: A, B

Explanation

Amazon RDS and Amazon Aurora are fully managed relational database services that support structured, predefined schemas. In contrast, Amazon DocumentDB is a document database, Amazon Neptune is a graph database, and Amazon DynamoDB is a key-value/document NoSQL database, none of which are designed for traditional relational schemas.
