Explanation:
AWS Budgets allows you to set custom budgets to track your cost and usage from the simplest to the most complex use cases. You can create recurring budgets and set up alerts for both actual (current) costs and forecasted costs. These alerts can be configured to send notifications directly to an Amazon SNS topic. This is a built-in feature and requires the least operational overhead compared to custom solutions using AWS Step Functions, Lambda, or manual checks.

Question 3
A company needs to track spending in its AWS account. The company must receive a notification when current costs and forecasted costs exceed specific thresholds.
Which solution will meet these requirements with the LEAST operational overhead?
A
Create a new IAM role. Attach the AWSPurchaseOrdersServiceRolePolicy AWS managed policy to the role. Check AWS Cost Explorer on a regular basis to monitor current costs and forecasted costs.
B
Create an AWS Cost and Usage Report. Create an AWS Step Functions state machine that runs when a new usage file is generated. Configure the state machine to pass the data to Amazon Forecast and to invoke an AWS Lambda function. Configure the Lambda function to parse the data and to send a notification to an Amazon Simple Notification Service (Amazon SNS) topic if costs exceed the thresholds.
C
Create an AWS Cost and Usage Report. Separate the current costs and forecasted costs by service. Schedule the report to be sent to an Amazon Simple Notification Service (Amazon SNS) topic each month.
D
Create a recurring cost budget in AWS Budgets. Create an alert for the actual cost. Create a second alert for the forecasted costs. Configure an Amazon Simple Notification Service (Amazon SNS) topic to receive the alerts.
