An ecommerce company is receiving reports that its order history page is experiencing delays in reflecting the processing status of orders. The order processing system consists of an AWS Lambda function that uses reserved concurrency.

Answers
Suggested answer: A

Explanation:

Step 1: Reacting to RDS Storage Autoscaling Events Using Amazon EventBridge Amazon RDS emits events when storage autoscaling occurs. To visualize these events in a CloudWatch dashboard, you can create an EventBridge rule that listens for these specific autoscaling events. Action: Create an EventBridge rule that reacts to RDS storage autoscaling events from the RDS event stream. Why: EventBridge allows you to listen to RDS events and route them to specific AWS services for processing.

Step 2: Creating a Custom CloudWatch Metric via Lambda Once the EventBridge rule detects a storage autoscaling event, you can use a Lambda function to publish a custom metric to CloudWatch. This metric can then be visualized in a CloudWatch dashboard. Action: Use a Lambda function to publish custom metrics to CloudWatch based on the RDS storage autoscaling events. Why: Custom metrics allow you to track specific events like autoscaling and visualize them easily on a CloudWatch dashboard.

This corresponds to Option A: Create an Amazon EventBridge rule that reacts to RDS storage autoscaling events from RDS events. Create an AWS Lambda function that publishes a CloudWatch custom metric. Configure the EventBridge rule to invoke the Lambda function. Visualize the custom metric by using the CloudWatch dashboard.

A company has an AWS Cloud Format ion slack that is deployed in a single AWS account. The company has configured the stack to send event notifications to an Amazon Simple Notification Service (Amazon SNS) topic.

A DevOps engineer must implement an automated solution that applies a tag to the specific Cloud Formation stack instance only after a successful stack update occurs. The DevOps engineer has created an AWS Lambda function that applies and updates this tag (or the specific slack instance.

Which solution will meet these requirements?

A.
Run the AWS-UpdateCloudfomationStack AWS Systems Manager Automation runbook when Systems Manager detects an UPDATE_COMPLETE event for the instance status of the Cloud Formation stack. Configure the runbook to invoke the Lambda function.

D.
Adjust the configuration of the CloudFormation stack to send notifications for only an UPDATE COMPLETE instance status event to the SNS topic. Subscribe the Lambda function to the SNS topic.
Answers
Suggested answer: C

Explanation:

Step 1: Reacting to CloudFormation Stack Events with EventBridge AWS CloudFormation emits events during the lifecycle of a stack, including the UPDATE_COMPLETE event after a successful stack update. You can use Amazon EventBridge to detect this event and trigger a specific action (such as invoking a Lambda function). Action: Create an EventBridge rule that listens for the UPDATE_COMPLETE event for the CloudFormation stack. Why: EventBridge allows you to automatically detect CloudFormation stack lifecycle events and take action based on them.

Step 2: Invoking the Lambda Function After the EventBridge rule detects the UPDATE_COMPLETE event, it can invoke the pre-configured Lambda function to apply or update the tag on the specific CloudFormation stack instance. Action: Configure the EventBridge rule to invoke the Lambda function when the UPDATE_COMPLETE event occurs. Why: This automation ensures that the tag is applied immediately after a successful stack update without any manual intervention.

This corresponds to Option C: Create an Amazon EventBridge rule that matches the UPDATE_COMPLETE event pattern for the instance status of the CloudFormation stack. Configure the rule to invoke the Lambda function.
