AWS Certified SysOps Administrator – Associate — Question 92

A SysOps administrator needs to develop a solution that provides email notification and inserts a record into a database every time a file is put into an Amazon S3 bucket.

What is the MOST operationally efficient solution that meets these requirements?

Answer options

• A. Set up an S3 event notification that targets an Amazon Simple Notification Service (Amazon SNS) topic. Create two subscriptions for the SNS topic. Use one subscription to send the email notification. Use the other subscription to invoke an AWS Lambda function that inserts the record into the database.
• B. Set up an Amazon CloudWatch alarm that enters ALARM state whenever an object is created in the S3 bucket. Configure the alarm to invoke an AWS Lambda function that sends the email notification and inserts the record into the database.
• C. Create an AWS Lambda function to send the email notification and insert the record into the database whenever a new object is detected in the S3 bucket. Invoke the function every minute with an Amazon EventBridge (Amazon CloudWatch Events) scheduled rule.
• D. Set up two S3 event notifications. Target a separate AWS Lambda function with each notification. Configure one function to send the email notification. Configure the other function to insert the record into the database.

Correct answer: A

Explanation

Option A is the most operationally efficient solution as it leverages S3 event notifications and SNS to seamlessly handle both the email notification and database insertion in a single workflow. Option B introduces unnecessary complexity with CloudWatch alarms, while Option C relies on a scheduled invocation which is not event-driven. Option D complicates the setup by requiring two separate Lambda functions instead of utilizing a single function to handle both tasks.
