Full question →mediummultiple choiceObjective-mapped
A company has 20 AWS accounts managed under AWS Organizations. The finance team wants to centralize billing so that the company receives volume discounts for the aggregated usage across all accounts. Additionally, the team needs to set monthly budgets for each department and automatically receive email notifications when a department's spending reaches 80% of its budget threshold. Which combination of AWS features or services should the company use to meet these requirements?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Distractor review
AWS Cost Explorer with AWS Budgets
AWS Cost Explorer is a tool for analyzing historical cost data and usage patterns, but it does not automatically send proactive notifications when a budget threshold is exceeded. While AWS Budgets provides alerts, Cost Explorer is not required for budget alerts. More importantly, Cost Explorer alone does not enable volume discounts. Consolidated Billing is the mechanism that aggregates usage across accounts for discounts.
B
Best answer
Consolidated Billing with AWS Budgets
Consolidated Billing in AWS Organizations aggregates all account usage into a single bill, enabling the company to receive volume discounts (e.g., tiered pricing for EC2, S3). AWS Budgets allows the finance team to set custom budgets for each department and automatically send email notifications when actual or forecasted costs reach a defined threshold (e.g., 80%). This combination meets both requirements.
C
Distractor review
AWS Trusted Advisor with Consolidated Billing
AWS Trusted Advisor provides cost optimization recommendations (e.g., idle resources, reserved instance opportunities) but does not offer the ability to set custom budget thresholds or automatically send alerts when spending exceeds a percentage of a budget. Consolidated Billing alone does not provide budget alerts.
D
Distractor review
AWS Cost Explorer with AWS Organizations
AWS Organizations provides centralized management of multiple accounts, but unless the Consolidated Billing feature is enabled, accounts remain on separate bills and do not aggregate usage for volume discounts. Cost Explorer is for visualizing costs, not for automated budget alerts. This combination does not fulfill the requirement for centralized billing discounts or automated budget notifications.
Common exam trap
Common exam trap: NAT rules depend on direction and matching traffic
NAT is not only about the public address. The inside/outside interface roles and the ACL or rule that matches traffic are just as important.
Technical deep dive
How to think about this question
NAT questions usually test address translation, overload/PAT behaviour, static mappings and whether the right traffic is being translated. Read the interface direction and address terms carefully.
KKey Concepts to Remember
- Static NAT maps one inside address to one outside address.
- PAT allows many inside hosts to share one public address using ports.
- Inside local and inside global describe the private and translated addresses.
- NAT ACLs identify traffic for translation, not always security filtering.
TExam Day Tips
- Identify inside and outside interfaces first.
- Check whether the scenario needs static NAT, dynamic NAT or PAT.
- Do not confuse NAT matching ACLs with normal packet-filtering intent.

Question 1
A developer needs to launch a test server for a new application prototype. The developer logs into the AWS Management Console, selects an Amazon EC2 instance type, configures the security group, and starts the instance. The instance is running within two minutes, and the developer did not need to submit a formal request to the company's IT procurement team or wait for approval from a cloud administrator. Which essential characteristic of cloud computing does this scenario best demonstrate?
Question 2
A solutions architect is planning a new web application on AWS. The workload will include 3 Amazon EC2 instances (t3.medium) running 24/7, an Application Load Balancer, and an Amazon RDS for MySQL db.t3.small database. The architect needs to estimate the monthly cost for the first year, considering different purchasing options (On-Demand, 1-year All Upfront Reserved Instance, and Compute Savings Plan). Which AWS tool should the architect use to create this estimate?
Question 3
A company's development team frequently needs temporary test environments. A developer can log into the AWS Management Console, select an Amazon EC2 instance type, configure storage, and launch the instance within minutes without any interaction with the IT infrastructure team. This capability is an example of which essential characteristic of cloud computing?
Question 4
A company's finance team needs to analyze AWS spending in detail. They require a report that includes hourly cost data for each AWS service, each individual resource (e.g., a specific EC2 instance), and any cost allocation tags applied. The team plans to export this data to an Amazon S3 bucket and then import it into a custom business intelligence (BI) analytics dashboard. Which AWS tool should the finance team use to generate this level of detailed cost data?
Question 5
A company uses AWS for its development environment. The finance team wants to set a monthly budget of $10,000. They want to receive an email notification when the actual costs reach 80% of the budget ($8,000) and again when costs exceed the budget. The team needs a managed AWS service that can automatically send these alerts without requiring custom code or third-party tools. Which AWS service should the team use?
Question 6
A company uses AWS Organizations to manage multiple accounts. The security team needs to enforce a policy that restricts SSH access (port 22) from the internet (0.0.0.0/0) in all VPCs across all accounts. The team wants to centrally define the allowed rules and automatically apply them to newly created VPCs and security groups, while also automatically remediating any existing non-compliant security groups. Which AWS service should the team use?
FAQ
Questions learners often ask
What does this CLF-C02 question test?
Static NAT maps one inside address to one outside address.
What is the correct answer to this question?
The correct answer is: Consolidated Billing with AWS Budgets — Consolidated Billing within AWS Organizations aggregates usage across all member accounts, allowing the company to benefit from volume pricing discounts. AWS Budgets enables setting custom monthly budgets for each department and can trigger email notifications (via Amazon SNS) when actual or forecasted costs exceed specified thresholds (e.g., 80% of budget). AWS Cost Explorer is a visualization tool for analyzing historical costs and usage, but it does not automatically send proactive budget alerts. AWS Trusted Advisor provides cost optimization recommendations, not budget threshold alerts. Therefore, the correct combination is Consolidated Billing for volume discounts and AWS Budgets for automated budget alerts.
