AWS Certified Cloud Practitioner — Question 799

A company must store call recordings for 6 years. The storage system should be highly durable and cost-effective.

Which AWS service meets these requirements?

Answer options

• A. AWS Snowball
• B. Amazon S3
• C. AWS Storage Gateway
• D. Amazon Kinesis

Correct answer: B

Explanation

Amazon S3 is the ideal choice because it provides highly durable storage with cost-effective archival classes like S3 Glacier, which are perfect for long-term retention of historical data like call recordings. AWS Snowball is a physical data transfer device, and AWS Storage Gateway is used to connect on-premises environments to cloud storage, meaning neither is a primary long-term storage service. Amazon Kinesis is designed for real-time streaming data ingestion rather than long-term, low-cost archival storage.
