- A
Use Amazon EFS for shared file storage and Amazon S3 for long-term archiving.
- B
Use Amazon EBS for concurrent access and Amazon S3 for long-term archiving.
- C
Use Amazon EFS for shared file storage and Amazon S3 Glacier for long-term archiving.
- D
Use Amazon EFS for shared file storage and Amazon EBS for long-term archiving.
- E
Use Amazon S3 for shared file storage and Amazon S3 Glacier for long-term archiving.
Show answer and explanation
Correct answers: A, C
Explanation
The platform requires shared file storage with concurrent access and low-latency data access, which is best addressed by Amazon EFS. For long-term storage of processed data at the lowest cost, Amazon S3 or Amazon S3 Glacier is the best choice. Combining these storage solutions ensures that both operational and archival requirements are met efficiently.
- A. Correct.
This is a correct answer. Amazon EFS is designed for shared file storage with concurrent access by multiple applications, while Amazon S3 is well-suited for long-term archiving of data.
- B. Incorrect.
This is incorrect. Amazon EBS is a block storage service and does not support concurrent access from multiple applications. Amazon S3 is appropriate for long-term archiving but does not fulfill the shared file storage requirement.
- C. Correct.
This is a correct answer. Amazon EFS can handle shared file storage with low-latency access, and Amazon S3 Glacier is optimized for long-term storage at the lowest cost.
- D. Incorrect.
This is incorrect. While Amazon EFS is suitable for shared file storage, Amazon EBS is not appropriate for long-term archiving as it is a block storage service designed for single-instance use.
- E. Incorrect.
This is incorrect. Amazon S3 is not designed for shared file storage with concurrent access; it is an object storage service. Amazon S3 Glacier is appropriate for long-term archiving, but this option does not fulfill the shared file storage requirement.
