AWS Budgets

Correct Answer: Setting up budget alerts with a threshold based on a percentage of the budgeted amount

Setting up budget alerts with a threshold based on a percentage of the budgeted amount is the correct option. AWS Budgets allows you to set up alerts that notify you when your actual costs exceed a specified percentage of your budgeted amount. This helps you proactively monitor and control your spending. Configuring budget actions to automatically stop resources is not the best option because it can disrupt your applications and services. Defining the budget scope based on specific services or accounts is useful for granular cost monitoring but does not directly address receiving notifications when costs exceed a percentage of the budget. Enabling cost anomaly detection is helpful for identifying unusual spending patterns but is not specifically designed for alerting based on a percentage threshold of the budgeted amount.

Correct Answer: AWS Budgets allows you to set custom budgets and receive alerts when your costs or usage exceed the budgeted amount.

AWS Budgets is the correct answer because it allows you to set custom budgets based on your cost and usage preferences. It sends alerts when your actual or forecasted costs exceed the budgeted amounts, helping you proactively manage your AWS spending. AWS Cost Explorer provides detailed cost and usage reports for analysis, but lacks the ability to set budgets and alerts. AWS Trusted Advisor offers cost optimization recommendations, but does not support custom budget creation or overspending alerts. AWS Cost and Usage Reports generate detailed cost and usage data files, but do not provide real-time budget tracking or alerting capabilities.

Correct Answer: Use AWS Budgets to set up a cost budget with alerts triggered when actual costs exceed the budgeted amount. Configure a budget action to automatically stop EC2 instances when the actual costs exceed the budget by a specified threshold.

The best solution is to use AWS Budgets to set up a cost budget with alerts triggered when actual costs exceed the budgeted amount and configure a budget action to automatically stop EC2 instances when the actual costs exceed the budget by a specified threshold. This combination of services directly addresses the requirements of monitoring costs, alerting stakeholders when costs exceed the budget, and automatically stopping resources (EC2 instances) when costs significantly surpass the budget. AWS Cost Explorer is used for analyzing and visualizing costs but does not provide the automated alerting and resource stopping capabilities needed. CloudWatch alarms can monitor costs and send notifications, but it would require additional setup with Systems Manager Automation to stop EC2 instances. Cost Anomaly Detection identifies unusual spending patterns but does not provide the granular budget alerts and automated resource stopping actions required in this scenario.
