How does AWS Budgets notify you when your costs exceed a threshold?

You set a budget in AWS Budgets with an alert threshold of 80% of your monthly budget. What happens when your actual costs reach 85%?

A AWS Budgets sends an email notification to the contacts you specified.

B AWS automatically stops all running resources to prevent further costs.

C AWS Budgets increases your budget limit automatically to avoid service interruption.

D No notification is sent until the budget reaches 100%.

💡 Hint

Think about how AWS Budgets alerts work to keep you informed.

AWS Budgets sends notifications to alert you when your costs exceed the thresholds you set. It does not stop resources or change budgets automatically.

❓ Configuration

Which AWS service must be enabled to receive billing alerts via SNS?

You want to receive billing alerts through Amazon SNS notifications. Which AWS service must you enable first?

A AWS Budgets

B AWS Billing Alerts (via CloudWatch billing alarms)

C AWS Cost Explorer

D AWS CloudTrail

💡 Hint

Billing alerts via SNS are linked to a specific AWS monitoring service.

To receive billing alerts via SNS, you must enable AWS Billing Alerts, which are CloudWatch billing alarms that monitor your estimated charges.

❓ Architecture

Designing a multi-account billing alert system

You manage multiple AWS accounts under AWS Organizations. You want a centralized billing alert system that notifies your finance team when any account exceeds its budget. Which architecture is best?

A Set up AWS Budgets in each account separately and configure SNS topics in each account to notify the finance team.

B Use AWS Config rules in each account to monitor billing and send alerts to the finance team.

C Create CloudWatch billing alarms in each account and send alerts to individual email addresses per account.

D Use the master payer account to create consolidated AWS Budgets and configure a single SNS topic for alerts across all linked accounts.

💡 Hint

Think about how AWS Organizations and consolidated billing work together.

The master payer account can create consolidated budgets that cover all linked accounts, allowing centralized alerting via a single SNS topic.

❓ security

Securing billing alert notifications

You want to ensure that only authorized users can modify billing alert configurations and receive notifications. Which AWS feature helps enforce this?

A Enable AWS WAF on the billing alert SNS topic.

B Use AWS Shield to protect billing alert endpoints.

C Attach IAM policies to restrict access to AWS Budgets and SNS topics.

D Configure billing alerts to use public email addresses only.

💡 Hint

Think about controlling who can change settings and who can receive alerts.

IAM policies control permissions for AWS Budgets and SNS, ensuring only authorized users can modify alerts or subscribe to notifications.

Optimizing billing alert thresholds for cost control

Your company wants to catch unexpected cost spikes early without causing alert fatigue. Which billing alert threshold strategy is best?

A Set multiple alerts at 50%, 75%, and 90% of the budget to provide early warnings and escalate notifications.

B Set a single alert at 100% of the monthly budget to notify only when the budget is fully used.

C Set alerts only at 90% and 100% to reduce the number of notifications sent.

D Do not set alerts; rely on monthly billing reports to review costs.

💡 Hint

Think about balancing early detection with avoiding too many alerts.

Multiple alert thresholds allow early detection of cost increases and help teams respond before the budget is fully consumed, reducing surprises.
