AWS Certified Cloud Practitioner — Question 10

A bank needs to store recordings of calls made to its contact center for 6 years. The recordings must be accessible within 48 hours from the time they are requested.
Which AWS service will provide a secure and cost-effective solution for retaining these files?

Answer options

• A. Amazon DynamoDB
• B. Amazon S3 Glacier
• C. Amazon Connect
• D. Amazon ElastiCache

Correct answer: B

Explanation

Amazon S3 Glacier is designed for long-term data storage and offers a cost-effective solution for retaining large amounts of data, such as call recordings, while also allowing retrieval within a specified timeframe. In contrast, Amazon DynamoDB is a NoSQL database service not suited for long-term storage of large files, Amazon Connect is a contact center service without storage capabilities, and Amazon ElastiCache is used for in-memory caching rather than data retention.
