SAA-C03 Question 148
Single answerA company is building an application that requires low-latency access to data for a database. The storage solution must provide block-level storage with consistent performance and the ability to be attached to an EC2 instance. Which AWS storage type is the most suitable for this requirement?
- A
Amazon S3
- B
Amazon EFS
- C
Amazon EBS
- D
Amazon Glacier
Show answer and explanation
Correct answer: C
Explanation
Amazon EBS (Elastic Block Store) is specifically designed to provide block-level storage for use with EC2 instances. It offers low-latency performance and is well-suited for database applications that require consistent IOPS and low latency. Other options, such as S3, EFS, and Glacier, do not meet the low-latency or block-level storage criteria required for the given use case.
- A. Incorrect.
Amazon S3 is an object storage service designed for storing large volumes of unstructured data. It is not suitable for low-latency, block-level storage use cases.
- B. Incorrect.
Amazon EFS is a file storage service that provides shared access to files across multiple instances. While it supports low-latency access for file storage, it does not provide block-level storage.
- C. Correct.
Amazon EBS is a block storage service that delivers low-latency, consistent performance and can be attached to EC2 instances, making it the ideal option for this scenario.
- D. Incorrect.
Amazon Glacier is a storage service designed for long-term, archival data with infrequent access patterns. It is not suitable for low-latency or block-level storage requirements.
