SAA-C03 Question 212
Single answerA company is designing a new web application that will allow users to upload and manage photos. The application requires a storage solution that provides high durability, supports automatic replication across multiple Availability Zones, and offers lifecycle management to transition objects to lower-cost storage tiers. Which AWS storage service should the company choose?
- A
Amazon S3
- B
Amazon EBS
- C
Amazon EFS
- D
AWS Storage Gateway
Show answer and explanation
Correct answer: A
Explanation
Amazon S3 is the best choice for this scenario because it provides highly durable, multi-AZ object storage with built-in lifecycle management capabilities. These features make it ideal for applications requiring reliable storage and cost optimization. Other options, such as Amazon EBS and Amazon EFS, are better suited for specific use cases like block storage or file storage, but they do not meet the requirements for object storage with multi-AZ durability and lifecycle management.
- A. Correct.
Amazon S3 is designed for 99.999999999% durability, automatically replicates objects across multiple Availability Zones, and supports lifecycle management policies to transition objects to lower-cost storage tiers.
- B. Incorrect.
Amazon EBS is a block storage service designed for use with EC2 instances. It is not a multi-AZ solution by default, and it does not provide object lifecycle management features.
- C. Incorrect.
Amazon EFS is a scalable file storage solution for use with EC2 instances. While it supports multi-AZ replication, it is not optimized for object storage or lifecycle management.
- D. Incorrect.
AWS Storage Gateway is a hybrid storage solution that connects on-premises environments to AWS. It does not natively support multi-AZ replication or lifecycle management for transitioning objects to lower-cost storage tiers.
