AWS Certified Database – Specialty — Question 170

A gaming company has recently acquired a successful iOS game, which is particularly popular during the holiday season. The company has decided to add a leaderboard to the game that uses Amazon DynamoDB. The application load is expected to ramp up over the holiday season.
Which solution will meet these requirements at the lowest cost?

Answer options

• A. DynamoDB Streams
• B. DynamoDB with DynamoDB Accelerator
• C. DynamoDB with on-demand capacity mode
• D. DynamoDB with provisioned capacity mode with Auto Scaling

Correct answer: D

Explanation

The correct answer is D because using provisioned capacity mode with Auto Scaling allows the company to adjust capacity automatically based on demand, ensuring cost efficiency during peak times without over-provisioning resources. Options A and B do not directly address the capacity scaling needs, while option C may incur higher costs during the holiday season due to unpredictable loads.
