SAA-C03 Question 377
Single answerA company needs to store a large volume of infrequently accessed log data for regulatory compliance purposes. The log data must be retained for 7 years, and the solution should minimize costs while ensuring data durability. Which storage solution should the company choose?
- A
Amazon S3 Standard storage class
- B
Amazon S3 Glacier Deep Archive storage class
- C
Amazon EBS General Purpose SSD (gp3)
- D
Amazon RDS with automated backups
Show answer and explanation
Correct answer: B
Explanation
To design a cost-optimized storage solution for infrequently accessed data with long-term retention requirements, Amazon S3 Glacier Deep Archive is the best choice. It provides the lowest storage cost in S3 while maintaining high durability, which makes it ideal for long-term archival storage of log data. Other options such as S3 Standard, EBS, and RDS are either too expensive or unsuitable for this specific use case.
- A. Incorrect.
Amazon S3 Standard is designed for frequently accessed data and provides low latency and high availability. However, it is not cost-optimized for long-term storage of infrequently accessed data like log files.
- B. Correct.
Amazon S3 Glacier Deep Archive is the most cost-effective storage class for long-term retention of infrequently accessed data, such as regulatory log data. It is designed specifically for archival use cases with the lowest storage cost in S3.
- C. Incorrect.
Amazon EBS General Purpose SSD (gp3) is a block storage option optimized for high-performance workloads like databases and applications. It is not cost-efficient for storing large volumes of infrequently accessed log data.
- D. Incorrect.
Amazon RDS with automated backups is a database solution, and automated backups are designed for database recovery. It is not suitable for storing log data or ensuring cost optimization for such use cases.
