AWS Certified Cloud Practitioner — Question 40

A retail company needs to build a highly available architecture for a new ecommerce platform. The company is using only AWS services that replicate data across multiple Availability Zones.
Which AWS services should the company use to meet this requirement? (Choose two.)

Answer options

• A. Amazon EC2
• B. Amazon Elastic Block Store (Amazon EBS)
• C. Amazon Aurora
• D. Amazon DynamoDB
• E. Amazon Redshift

Correct answer: C, D

Explanation

Amazon Aurora and Amazon DynamoDB are the correct choices as both services are designed to automatically replicate data across multiple Availability Zones, ensuring high availability. In contrast, Amazon EC2 and Amazon Elastic Block Store (Amazon EBS) do not inherently offer this level of data replication for high availability, while Amazon Redshift is primarily focused on data warehousing rather than availability across zones.
