SAA-C03 Question 213
Single answerA company needs to store critical financial data and requires a storage solution that provides high durability, automatic replication across multiple Availability Zones (AZs), and supports encryption at rest. Which Amazon S3 storage class is the most appropriate for this use case?
- A
Amazon S3 Standard
- B
Amazon S3 Intelligent-Tiering
- C
Amazon S3 Glacier
- D
Amazon S3 One Zone-IA
Show answer and explanation
Correct answer: A
Explanation
Amazon S3 Standard is the most suitable option for critical financial data storage because it provides high durability (11 nines), automatic replication across multiple Availability Zones, and encryption at rest, fulfilling all the requirements specified in the scenario.
- A. Correct.
Amazon S3 Standard is designed for high durability (99.999999999% or 11 nines), automatic replication across multiple AZs, and supports encryption at rest, making it the most appropriate choice for storing critical financial data.
- B. Incorrect.
Amazon S3 Intelligent-Tiering is designed for cost optimization by automatically moving data between access tiers, but it may incur additional costs and complexity for critical financial data storage. It also provides high durability but is not the primary choice for this specific use case.
- C. Incorrect.
Amazon S3 Glacier is optimized for archival storage and has high durability, but it is not suitable for frequently accessed financial data due to its retrieval time and cost implications.
- D. Incorrect.
Amazon S3 One Zone-IA stores data in a single Availability Zone, making it less durable and less fault-tolerant compared to Amazon S3 Standard. It is not appropriate for critical financial data that requires high durability and automatic replication across multiple AZs.
