Question
A company is creating a mobile financial app that gives users the ability to sign up and store personal information. The app uses an Amazon DynamoDB table to store user details and preferences. The app generates a credit score report by using the data that is stored in DynamoDB. The app sends credit score reports to users once every month. The company needs to provide users with an option to remove their data and preferences. The app must delete customer data within one month of receiving a request to delete the data. Which solution will meet these requirements with the LEAST operational overhead?

Explanation
Enabling DynamoDB TTL (Time to Live) allows automatic expiration and deletion of items based on an attribute, minimizing operational overhead. By setting the TTL when a user requests data deletion, DynamoDB automatically removes the user data within the required one-month period without the need for additional scheduling or event-driven mechanisms.
