A media company has a multi-account AWS environment in the us-east-1 Region. The company has an Amazon Simple Notification Service {Amazon SNS) topic in a production account that publishes performance metrics. The company has an AWS Lambda function in an administrator account to process and analyze log data.

The Lambda function that is in the administrator account must be invoked by messages from the SNS topic that is in the production account when significant metrics tM* reported.

Which combination of steps will meet these requirements? (Select TWO.)

A.
Create an IAM resource policy for the Lambda function that allows Amazon SNS to invoke the function. Implement an Amazon Simple Queue Service (Amazon SQS) queue in the administrator account to buffer messages from the SNS topic that is in the production account. Configure the SOS queue to invoke the Lambda function.

Answers
D.
Store performance metrics in an Amazon S3 bucket in the production account. Use Amazon Athena to analyze the metrics from the administrator account.
Suggested answer: A, B

Explanation:

Requirement Analysis: The Lambda function in the administrator account needs to process messages from an SNS topic in the production account.

IAM Policy for SNS Topic: Allows the Lambda function to subscribe and be invoked by the SNS topic.

SQS Queue for Buffering: Using an SQS queue provides reliable message delivery and buffering between SNS and Lambda, ensuring all messages are processed.

Implementation:

Create an SQS queue in the administrator account.

Set an IAM policy to allow the Lambda function to subscribe to and be invoked by the SNS topic.

Configure the SNS topic to send messages to the SQS queue.

Set up the SQS queue to trigger the Lambda function.

Conclusion: This solution ensures reliable message delivery and processing with appropriate permissions.
