CLF-C02 By islever Editorial Last updated

Identify AWS database services.

Short answer

B Amazon DynamoDB is the AWS service that provides the ability to host a NoSQL database in the AWS Cloud.

Question

Which AWS service provides the ability to host a NoSQL database in the AWS Cloud?
  1. Amazon Aurora
  2. Amazon DynamoDB Correct Answer
  3. Amazon RDS
  4. Amazon Redshift

Key Takeaways

This question tests knowledge of specific database engine types (NoSQL vs SQL) offered by AWS managed services, with the common trap being confusion between relational and non-relational options.

Amazon DynamoDB is the AWS service designed for hosting NoSQL databases, offering single-digit millisecond performance and seamless scalability in the cloud.

Common mistake: Candidates often select Amazon RDS or Aurora because they are popular database services, but these support relational (SQL) engines rather than NoSQL.

Expert Analysis

Why the Answer Is Correct

Amazon DynamoDB is a fully managed, serverless NoSQL database service provided by AWS. It supports key-value and document data structures, making it the correct choice for hosting NoSQL workloads. It provides built-in security, continuous backups, and on-demand auto-scaling.

Why the Other Options Are Wrong

Amazon Aurora and Amazon RDS are relational database services that support SQL engines like MySQL, PostgreSQL, and Oracle. Amazon Redshift is a data warehouse service optimized for OLAP queries, not general-purpose NoSQL transactional storage.

Community Comment Notes

The community consensus strongly supports DynamoDB as the answer. As noted by user bindu991, "https://docs.aws.amazon.com/amazondynamodb/latest/developerguide/Introduction.html" confirms its role as a NoSQL database. User BShelat also cited the same documentation to validate the selection.
