CV0-004 Operations and Support Practice Question
A company wants to be notified when their monthly AWS spending exceeds $10,000. Which AWS service should they use to set up this alert?
⚠ Common exam trap
CV0-004 often tests the difference between cost visibility tools and cost alerting tools — candidates pick Cost Explorer or Trusted Advisor for notifications, when only AWS Budgets is designed to alert on spending thresholds.

Why each option matters
Answer the question above first, then reveal the full breakdown to understand why each option is right or wrong.
Correct answer & explanation
✓
AWS Budgets
AWS Budgets allows you to set custom cost budgets and configure alerts when actual or forecasted spending exceeds a defined threshold, such as $10,000 per month. It sends notifications via email or SNS when the threshold is breached, directly satisfying the requirement to be notified about monthly spending exceeding a specific amount.
Answer analysis
Option-by-option breakdown
For each option: why learners choose it and why it is or isn't the right answer here.
- ✗
AWS Trusted Advisor
Why it's wrong here
Trusted Advisor inspects account configuration against best-practise checks and surfaces cost-optimisation recommendations, but it neither tracks month-to-date spend nor sends threshold notifications. It tempts because it does report cost findings, yet AWS Budgets is the service that monitors actual spend against a defined limit.
- ✓
AWS Budgets
Why this is correct
AWS Budgets lets you define a monthly cost budget with a threshold and configure alerts when actual or forecast spend exceeds it. This directly satisfies the $10,000 notification requirement, whereas CloudWatch alarms track metrics rather than billing amounts.
- ✗
AWS Cost Explorer
Why it's wrong here
Cost Explorer visualises and forecasts historical spending through reports and charts, but it does not evaluate a threshold or dispatch notifications. It tempts because it displays the cost data the alert concerns, yet AWS Budgets performs the monitoring and Amazon SNS the delivery.
- ✗
AWS CloudWatch Alarms
Why it's wrong here
CloudWatch Alarms monitor metrics such as CPU or custom metrics, not billing totals; they cannot natively trigger on AWS cost data. AWS Budgets is the service for spend thresholds, so it would be correct when alerting on forecasted or actual monthly account expenditure.
