SAP-C02 Question 663
Single answerA large media company is building a data analytics pipeline to process and analyze video metadata. The pipeline requires a shared storage solution for multiple analytics jobs running on Amazon EC2 instances across multiple Availability Zones. The solution must provide low-latency file access, support concurrent access from multiple instances, and automatically scale to handle increasing workloads. Which storage service should the company use?
- A
Amazon S3
- B
Amazon EFS
- C
Amazon FSx for Windows File Server
- D
Amazon Elastic Block Store (EBS)
Show answer and explanation
Correct answer: B
Explanation
Amazon EFS is the correct choice because it is a fully managed, scalable file storage service designed for concurrent access across multiple EC2 instances and Availability Zones. It provides low-latency file access and supports automatic scaling, making it ideal for the described data analytics pipeline. Other options like Amazon S3 and Amazon EBS do not meet the requirements for low-latency or shared file access, while Amazon FSx for Windows File Server is tailored for Windows-specific workloads.
- A. Incorrect.
Amazon S3 is an object storage service, which is not suitable for low-latency file access or concurrent access from multiple instances. It is better suited for storing and retrieving unstructured data like images, videos, or backups.
- B. Correct.
Amazon EFS (Elastic File System) is a fully managed, shared file storage solution that supports concurrent access from multiple EC2 instances and scales automatically. It is ideal for use cases requiring shared storage across multiple Availability Zones.
- C. Incorrect.
Amazon FSx for Windows File Server is a managed Windows file storage solution, typically used for applications requiring Windows-specific features like SMB protocol. It is not the best fit for a general-purpose, scalable, shared file storage solution needed here.
- D. Incorrect.
Amazon Elastic Block Store (EBS) provides block storage for a single EC2 instance at a time, making it unsuitable for a shared file storage solution across multiple instances or Availability Zones.
