Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company has multiple departments (HR, Finance, Engineering) sharing a single AWS account. Each department tags its resources with a 'Department' tag (e.g., Department:HR). The finance team wants to set monthly spending limits for each department and receive email alerts when a department's spending reaches 80% of its limit. They also want a visual dashboard to compare actual spending against the budgeted amounts. Which combination of AWS services should the finance team use?
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 and AWS Trusted Advisor
Incorrect. AWS Cost Explorer provides cost visualization and analysis, but AWS Trusted Advisor offers cost optimization recommendations and best practice checks, not budgeting or alerts. Trusted Advisor does not support setting spending limits or sending threshold alerts.
B
Distractor review
AWS Budgets and Amazon QuickSight
Incorrect. AWS Budgets can set spending limits and send alerts, which is correct. However, Amazon QuickSight is a business intelligence service that requires data preparation and setup to visualize AWS cost data. The simpler and more direct solution is AWS Cost Explorer, which is purpose-built for AWS cost visualization and does not require additional data integration.
C
Best answer
AWS Budgets and AWS Cost Explorer
Correct. AWS Budgets allows the finance team to create monthly cost budgets per department (using cost allocation tags) and configure alerts at 80% of the budgeted amount. AWS Cost Explorer provides a visual dashboard with charts and tables to compare actual spending against budgets, enabling the team to track progress without needing an external BI tool.
D
Distractor review
AWS Pricing Calculator and AWS Cost Explorer
Incorrect. AWS Pricing Calculator is used for estimating future costs of AWS services before deployment, not for setting budgets or alerts. AWS Cost Explorer alone cannot set budgets or send alerts. The team needs AWS Budgets for those capabilities.
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: AWS Budgets and AWS Cost Explorer — The finance team needs both a budgeting and an analysis tool. AWS Budgets allows creation of cost budgets with alerts based on actual or forecasted spending. AWS Cost Explorer provides interactive dashboards and graphs to visualize and analyze historical costs, including comparing actual spending against budget thresholds. Together, they meet the requirement for setting budgets and viewing progress. Cost Explorer does not directly set budgets, but it can display budget data when budgets are created. The combination of Budgets (for alerts) and Cost Explorer (for visual dashboards) is the appropriate solution.
