    26. Question

    A company has several development teams using AWS CodeCommit to store their source code. With the number of code updates every day, the management is having difficulty tracking if the developers are adhering to company security policies. On a recent audit, the security team found several IAM access keys and secret keys in the CodeCommit repository. This is a big security risk so the company wants to have an automated solution that will scan the CodeCommit repositories for committed IAM credentials and delete/disable the IAM keys for those users.

    Which of the following options will meet the company requirements?

    Using a development instance, use the AWS Systems Manager Run Command to scan the AWS CodeCommit repository for IAM credentials on a daily basis. If credentials are found, rotate them using AWS Secrets Manager. Notify the user of the violation.
    Download and scan the source code from AWS CodeCommit using a custom AWS Lambda function. Schedule this Lambda function to run daily. If credentials are found, notify the user of the violation, generate new IAM credentials and store them in AWS KMS for encryption.
    Write a custom AWS Lambda function to search for credentials on new code submissions. Set the function trigger as AWS CodeCommit push events. If credentials are found, notify the user of the violation, and disable the IAM keys.
    Scan the CodeCommit repositories for IAM credentials using Amazon Macie. Using machine learning, Amazon Macie can scan your repository for security violations. If violations are found, invoke an AWS Lambda function to notify the user and delete the IAM keys.

    Correct

    You can invoke an AWS Lambda function from an Amazon Aurora MySQL-Compatible Edition DB cluster with a native function or a stored procedure. This approach can be useful when you want to integrate your database running on Aurora MySQL with other AWS services. For example, you might want to capture data changes whenever a row in a table is modified in your database.

    In the scenario, you can trigger a Lambda function whenever a listing is deleted from the database. You can then write the logic of the function to send the listing data to an SQS queue and have different processes consume it.

    Hence, the correct answer is: Create a native function or a stored procedure that invokes a Lambda function. Configure the Lambda function to send event notifications to an Amazon SQS queue for the processing system to consume.

    RDS events only provide operational events such as DB instance events, DB parameter group events, DB security group events, and DB snapshot events. What we need in the scenario is to capture data-modifying events (INSERT, DELETE, UPDATE) which can be achieved through native functions or stored procedures. Hence, the following options are incorrect:

    – Create an RDS event subscription and send the notifications to Amazon SQS. Configure the SQS queues to fan out the event notifications to multiple Amazon SNS topics. Process the data using Lambda functions.

    – Create an RDS event subscription and send the notifications to AWS Lambda. Configure the Lambda function to fan out the event notifications to multiple Amazon SQS queues to update the processing system.

    – Create an RDS event subscription and send the notifications to Amazon SNS. Configure the SNS topic to fan out the event notifications to multiple Amazon SQS queues. Process the data using Lambda functions.

    At no point does the question ask about SQS
