- A
AWS Budgets with budget alerts only
Why wrong: Budget alerts notify you when thresholds are crossed but don't automatically stop resources — AWS Budgets Actions is needed for automated responses.
- B
AWS Budgets Actions
AWS Budgets Actions can automatically apply IAM policies to deny further usage, stop EC2/RDS instances, or trigger custom Lambda responses when budget thresholds are exceeded.
- C
AWS Cost Explorer spending forecasts
Why wrong: Cost Explorer forecasts project future costs based on trends — it doesn't automatically stop resources when projected costs reach a threshold.
- D
AWS Service Quotas
Why wrong: Service Quotas limit how many resources can be provisioned — they don't directly limit spending or stop resources based on cost.
Question 665 of 1,024
AWS Budgets Actions — Automated Resource Termination for Cost Limits
This CLF-C02 practice question tests your understanding of billing, pricing, and support. Match the stated requirement to the specific cloud service, access model, or configuration option — many options are valid in isolation but not for this scenario. After answering, compare your reasoning against the explanation and wrong-answer breakdown below. Once you have made your selection, read the full explanation to reinforce the concept and understand why each distractor is designed to mislead on exam day.
A company wants to ensure they never spend more than $500 per month on AWS services. Which AWS feature can automatically stop or terminate resources when cost projections reach a threshold?

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 Actions
AWS Budgets Actions allow you to define cost and usage budgets with automated responses, such as stopping or terminating EC2 instances, when actual or forecasted costs exceed a specified threshold. This directly meets the requirement to enforce a $500 monthly spending limit without manual intervention. Budget alerts alone only notify you; they do not take automated actions.
Key principle: Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.

Common exam traps
Common exam trap: answer the scenario, not the keyword
The trap here is that candidates confuse budget alerts (which only notify) with Budgets Actions (which automate responses), leading them to select Option A because they overlook the requirement for automatic resource termination.
Detailed technical explanation
How to think about this question
AWS Budgets Actions use AWS Identity and Access Management (IAM) roles and AWS Lambda or Systems Manager Automation runbooks to execute predefined actions, such as stopping EC2 instances via the `ec2:StopInstances` API call. The action can be triggered when actual or forecasted costs reach a user-defined percentage of the budget (e.g., 100% of $500). A real-world scenario is a development environment where a Budget Action automatically stops non-critical instances when monthly costs approach the limit, preventing surprise bills while preserving resources for the next cycle.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
TExam Day Tips
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.
Key takeaway
Answer the scenario, not the keyword: identify the specific constraint before choosing the most familiar-sounding option.
Real-world example
How this comes up in practice
A startup's cloud architect reviews their monthly bill and notices costs are higher than expected for a long-running batch job. Switching from on-demand instances to Reserved Instances — or using Spot/Preemptible VMs — can reduce compute costs by up to 72 %. Questions like this test whether you understand the tradeoffs between commitment, flexibility, and cost across cloud pricing models.
