Show answer and explanation
Correct answer: B
Explanation
For data that is rarely accessed but must be retained for compliance purposes, Amazon S3 Glacier Flexible Retrieval provides the most cost-effective solution. It is specifically designed for long-term archival storage, offering low-cost pricing while ensuring data can still be retrieved when needed, albeit with some retrieval latency.
- A. Incorrect.
Amazon S3 Standard storage class is designed for frequently accessed data. It provides low latency and high throughput but is more expensive than archival storage options, making it unsuitable for infrequently accessed archival data.
- B. Correct.
Amazon S3 Glacier Flexible Retrieval storage class is optimized for rarely accessed data that needs to be retained for long periods. It offers low-cost storage and is ideal for archival purposes, aligning well with the company's requirements.
- C. Incorrect.
Amazon S3 Intelligent-Tiering automatically moves data between different storage tiers based on access patterns. While this can be cost-effective for unpredictable access patterns, it is not the best choice for data that is rarely accessed and explicitly archived.
- D. Incorrect.
Amazon EBS General Purpose SSD (gp2) is a block storage option designed for high-performance workloads like databases and applications. It is not suitable for cost-effective archival storage.
