Full question →mediummultiple choiceObjective-mapped
A company runs a diverse workload on AWS that includes Amazon EC2 instances of various families and sizes across multiple regions, Amazon RDS databases, and a serverless application using AWS Lambda and AWS Fargate. The finance team wants to reduce compute costs by making a 1-year hourly spend commitment, but they need the flexibility to change instance families, sizes, regions, or switch between EC2, Fargate, and Lambda without losing the discount. Which AWS pricing model should the finance team choose 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
Best answer
Compute Savings Plan
Correct. Compute Savings Plans apply to any EC2 instance (any family, size, region), AWS Fargate, and AWS Lambda. They provide significant discounts in exchange for a consistent hourly spend commitment and offer the maximum flexibility to change instance attributes or move between compute services.
B
Distractor review
Reserved Instances (Standard)
Incorrect. Standard Reserved Instances provide a discount but are locked to a specific instance family and region. They do not cover AWS Fargate or AWS Lambda, and changing instance attributes would require purchasing new reservations.
C
Distractor review
Reserved Instances (Convertible)
Incorrect. Convertible Reserved Instances offer some flexibility to change instance family or region, but they still apply only to Amazon EC2 (not Fargate or Lambda) and require a 1:1 exchange of attributes. They also do not provide the broad service coverage of a Compute Savings Plan.
D
Distractor review
On-Demand
Incorrect. On-Demand pricing offers no commitment and results in the highest hourly cost. While it is flexible, it does not provide the cost savings the finance team is looking for.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
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.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- 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.

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?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Compute Savings Plan — Compute Savings Plans offer the flexibility required by this scenario. They apply to EC2 instance usage (across any instance family, size, or region), AWS Fargate, and AWS Lambda. By committing to a consistent amount of compute usage (measured in $/hour) for a 1- or 3-year term, customers receive a lower price compared to On-Demand. Standard Reserved Instances are tied to a specific instance family and region, while Convertible Reserved Instances allow changing family or region but still require a 1:1 exchange of attributes and do not cover Fargate or Lambda. On-Demand provides no discount. Therefore, Compute Savings Plan is the best choice for the described flexible, multi-service workload.
