SAA-C03 Question #531: Real Exam Question with Answer & Explanation

Question

A company is developing a photo-hosting application in the us-east-1 Region. The application gives users across multiple countries the ability to upload and view photos. Some photos are heavily viewed for months, while other photos are viewed for less than a week. The application allows users to upload photos that are up to 20 MB in size. The application uses photo metadata to determine which photos to display to each user. The company needs a cost-effective storage solution to support the application. Which solution will meet this requirement?

Options

• AStore the photos in Amazon DynamoDB. Turn on DynamoDB Accelerator (DAX).
• BStore the photos in the Amazon S3 Intelligent-Tiering storage class. Store the photo metadata
• CStore the photos in the Amazon S3 Standard storage class. Set up an S3 Lifecycle policy to move
• DStore the photos in an Amazon DynamoDB table. Use the DynamoDB Standard-Infrequent

Explanation

Amazon S3 Intelligent-Tiering automatically moves objects between frequent and infrequent access tiers based on access patterns, which minimizes cost without performance impact. Storing photo metadata in Amazon DynamoDB provides fast and scalable lookup by user or tag. "The S3 Intelligent-Tiering storage class automatically optimizes storage costs by moving data between frequent and infrequent access tiers when access patterns change." Why B is correct: S3 Intelligent-Tiering optimizes storage automatically for cost without lifecycle management DynamoDB stores small metadata items and S3 URLs, enabling efficient queries and photo This architecture scales globally, integrates seamlessly with applications, and minimizes operational cost. Why other options are incorrect: A & D: DynamoDB is not intended for storing binary objects like images. C: Lifecycle rules are static and don't adapt dynamically to unpredictable access patterns.
