Amazon Web Services DVA-C02 Question Answer

A company built an online event platform For each event the company organizes quizzes and generates leaderboards that are based on the quiz scores. The company stores the leaderboard data in AmazonDynamoDB and retains the data for 30 days after an event is complete The company then uses a scheduled job to delete the old leaderboard data

The DynamoDB table is configured with a fixed write capacity. During the months when many events occur, the DynamoDB write API requests are throttled when the scheduled delete job runs.

A developer must create a long-term solution that deletes the old leaderboard data and optimizes write throughput

Which solution meets these requirements?

Configure a TTL attribute for the leaderboard data

Use DynamoDB Streams to schedule and delete the leaderboard data

Use AWS Step Functions to schedule and delete the leaderboard data.

Set a higher write capacity when the scheduled delete job runs
