DVA-C02 Question 86
Select 1You are developing a serverless application that processes large image files uploaded by users. The application needs to store the uploaded images and metadata, while ensuring low latency access to the images. Additionally, the metadata needs to be searchable based on custom attributes. Which combination of AWS storage services should you use?
- A
Amazon S3 for storing the images and Amazon DynamoDB for storing the metadata
- B
Amazon EFS for storing the images and Amazon RDS for storing the metadata
- C
Amazon S3 for storing the images and Amazon RDS for storing the metadata
- D
Amazon EBS for storing the images and Amazon DynamoDB for storing the metadata
- E
Amazon EFS for storing the images and Amazon DynamoDB for storing the metadata
Show answer and explanation
Correct answer: A
Explanation
For this scenario, Amazon S3 is the best option for storing large image files due to its scalability, durability, and cost-effectiveness. Amazon DynamoDB is the best choice for storing metadata because it is a NoSQL database that allows for fast, efficient, and highly scalable queries based on custom attributes. This combination ensures low latency access to both the images and their metadata, making it an ideal solution for the application.
- A. Correct.
Correct. Amazon S3 is optimized for storing large objects like images, while Amazon DynamoDB is a NoSQL database that provides fast and efficient querying for metadata, especially for attributes-based searches.
- B. Incorrect.
Incorrect. Amazon EFS is designed for shared file storage and is not as cost-effective or scalable as Amazon S3 for storing large image files. While Amazon RDS can store metadata, it may not be the best choice for fast, attribute-based queries.
- C. Incorrect.
Incorrect. While Amazon S3 is a good choice for storing the images, Amazon RDS is a relational database that may not perform well for the type of metadata queries required here, especially if they are highly dynamic.
- D. Incorrect.
Incorrect. Amazon EBS is designed for block storage and is not suitable for directly storing large numbers of images. Additionally, while DynamoDB is suitable for metadata, this combination would not be ideal for the use case.
- E. Incorrect.
Incorrect. Amazon EFS is not the optimal choice for storing large image files, and while DynamoDB is suitable for metadata, this combination is not ideal for the given scenario.
