SAA-C03 Question 169
Single answerA company is migrating its on-premises application to AWS. The application stores large amounts of unstructured data, such as images and videos, and needs to provide low-latency access to this data for users worldwide. The company also requires the solution to be highly durable and scalable. Which AWS service should the Solutions Architect recommend?
- A
Amazon S3 with Transfer Acceleration
- B
Amazon RDS with global read replicas
- C
Amazon DynamoDB with global tables
- D
Amazon EFS with cross-region replication
Show answer and explanation
Correct answer: A
Explanation
Amazon S3 with Transfer Acceleration is the best choice for storing unstructured data such as images and videos. It provides high durability, virtually unlimited scalability, and low-latency access through Transfer Acceleration, which routes traffic through AWS Edge Locations. This makes it an ideal solution for applications requiring global performance and reliability.
- A. Correct.
Amazon S3 with Transfer Acceleration is a highly durable and scalable object storage service suitable for storing unstructured data like images and videos. Transfer Acceleration improves performance for users worldwide by leveraging AWS Edge Locations for faster data transfer.
- B. Incorrect.
Amazon RDS is a relational database service, which is optimized for structured data rather than unstructured data like images and videos. While global read replicas help with low-latency access, RDS is not designed for storing large, unstructured files.
- C. Incorrect.
Amazon DynamoDB is a NoSQL database service, which is optimized for key-value and document-based data. While it offers global tables for low-latency access, it is not suited for storing unstructured data like images and videos.
- D. Incorrect.
Amazon EFS is a file storage service for EC2 instances and is not designed for global access or optimized for unstructured data like videos and images. Cross-region replication also does not address the requirement for low-latency global access.
