AWS Certified Cloud Practitioner — Question 196

An application requires a database that offers consistent performance and latency that can be measured in single-digit milliseconds.

Which AWS service meets these requirements?

Answer options

• A. Amazon DynamoDB
• B. Amazon RDS
• C. Amazon Redshift
• D. Amazon EMR

Correct answer: A

Explanation

Amazon DynamoDB is designed for high performance with low latency, making it ideal for applications that require single-digit millisecond response times. In contrast, Amazon RDS, Amazon Redshift, and Amazon EMR are not optimized for such low-latency requirements, as they are geared towards relational databases, data warehousing, and big data processing respectively.
