AWS Certified Database – Specialty — Question 4

A company has an on-premises system that tracks various database operations that occur over the lifetime of a database, including database shutdown, deletion, creation, and backup.
The company recently moved two databases to Amazon RDS and is looking at a solution that would satisfy these requirements. The data could be used by other systems within the company.
Which solution will meet these requirements with minimal effort?

Answer options

• A. Create an Amazon CloudWatch Events rule with the operations that need to be tracked on Amazon RDS. Create an AWS Lambda function to act on these rules and write the output to the tracking systems.
• B. Create an AWS Lambda function to trigger on AWS CloudTrail API calls. Filter on specific RDS API calls and write the output to the tracking systems.
• C. Create RDS event subscriptions. Have the tracking systems subscribe to specific RDS event system notifications.
• D. Write RDS logs to Amazon Kinesis Data Firehose. Create an AWS Lambda function to act on these rules and write the output to the tracking systems.

Correct answer: C

Explanation

The correct answer, C, is appropriate because RDS event subscriptions are specifically designed to notify subscribers of changes and events in the RDS service, which aligns perfectly with the tracking requirements. The other options, while they might provide some level of tracking, involve more complex setups or do not directly address the need for event notifications from the RDS system.
