Answer: Activate DynamoDB Streams on the table and configure a trigger to send updates to a single Amazon SNS topic subscribed by all teams.
The correct answer is C. Enabling Amazon DynamoDB Streams on the table allows capturing changes to items in the table and triggering a notification process. By writing to a single Amazon SNS topic to which the teams can subscribe, this method ensures minimal operational overhead and does not impact the performance of the current application. This is more efficient compared to setting up individual SNS topics for each team or running a cron job to scan the table periodically.
