Exam AWS Certified Solutions Architect - Associate SAA-C03 topic 1 question 400 discussion

Answer A is not a suitable solution because it requires additional configuration to notify the internal teams, and it could add operational overhead to the application. Answer B is not the best solution because it requires changes to the current application, which may affect its performance, and it creates additional work for the teams to subscribe to multiple topics. Answer D is not a good solution because it requires a cron job to scan the table every minute, which adds additional operational overhead to the system. Therefore, the correct answer is C. Enable Amazon DynamoDB Streams on the table. Use triggers to write to a single Amazon SNS topic to which the teams can subscribe.

DynamoDB Streams captures a time-ordered sequence of item-level modifications in any DynamoDB table and stores this information in a log for up to 24 hours. This capture activity can also invoke triggers to write the event to a single Amazon Simple Notification Service (Amazon SNS) topic to which the teams can subscribe to.
