AWS Certified Big Data – Specialty — Question 5

An organization needs a data store to handle the following data types and access patterns:
✑ Faceting
✑ Search
✑ Flexible schema (JSON) and fixed schema
✑ Noise word elimination
Which data store should the organization choose?

Answer options

• A. Amazon Relational Database Service (RDS)
• B. Amazon Redshift
• C. Amazon DynamoDB
• D. Amazon Elasticsearch Service

Correct answer: C

Explanation

Amazon DynamoDB is the best choice for handling flexible schemas and can efficiently manage various access patterns including search and faceting. In contrast, Amazon RDS is suited for fixed schema databases, Amazon Redshift is optimized for analytics rather than search, and Amazon Elasticsearch Service, while good for search, does not provide the same level of support for flexible schemas as DynamoDB.
