Explanation

Explanation

Option C is correct because RDS Event Subscriptions are a native, purpose-built AWS feature designed specifically to track database lifecycle events such as creation, deletion, shutdown, and backup - exactly matching the on-premises requirements. Event subscriptions use Amazon SNS to publish notifications, allowing multiple downstream systems to easily subscribe and consume the data with minimal configuration effort.

Option A is incorrect because while CloudWatch Events (now EventBridge) can capture some RDS events, it requires more configuration and is not the most direct or minimal-effort solution for tracking RDS-specific operational events compared to native RDS event subscriptions.

Option B is incorrect because CloudTrail captures API calls (control plane actions) but does not comprehensively track all database operational events like backups or internal database lifecycle changes, and building a Lambda filtering solution adds unnecessary complexity.

Option D is incorrect because routing RDS logs to Kinesis Data Firehose with a Lambda function is an overly complex, high-effort architecture for what is essentially a notification/tracking requirement that RDS Event Subscriptions handle natively.

Memory Tip: Think of RDS Event Subscriptions as the "database diary" - it's the AWS-native way to subscribe to exactly the database lifecycle events you care about, similar to subscribing to a newsletter. If the question mentions tracking RDS operational events with minimal effort, always think Event Subscriptions + SNS.
