Question 1mediummultiple choice
Full question →mediummultiple choiceObjective-mapped
A company is planning to deploy a multi-tier web application on AWS. The architecture includes Amazon EC2 instances, an Application Load Balancer, an Amazon RDS database, and security groups. The company wants to define and provision these resources as reusable, version-controlled infrastructure so they can consistently deploy the same environment to development, testing, and production accounts. The solution should allow the team to use JSON or YAML templates to describe the resources and their dependencies. Which AWS service should the company 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 Elastic Beanstalk
AWS Elastic Beanstalk is a platform as a service that automates the deployment and scaling of applications. It does provision underlying resources, but it abstracts the infrastructure details and does not offer the ability to define the entire infrastructure as reusable JSON or YAML templates for version control. It is better suited for developers who want to focus on code rather than infrastructure management.
B
Best answer
AWS CloudFormation
AWS CloudFormation is an infrastructure as code service that enables you to model and provision AWS resources using templates written in JSON or YAML. These templates can be stored in version control systems, making it possible to deploy identical environments across multiple accounts and regions consistently.
C
Distractor review
AWS OpsWorks
AWS OpsWorks is a configuration management service that uses Chef and Puppet to manage server configurations. While it can be used to automate parts of infrastructure, it does not provide the same declarative, template-based infrastructure provisioning and version control capabilities that AWS CloudFormation offers.
D
Distractor review
AWS CodeDeploy
AWS CodeDeploy is a service that automates code deployments to any instance, including Amazon EC2 and on-premises servers. It handles the rollout of application updates, not the provisioning or definition of the underlying infrastructure resources.
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: AWS CloudFormation — AWS CloudFormation is the correct service because it allows you to define your entire AWS infrastructure as code using JSON or YAML templates. These templates can be version-controlled in a repository and reused across multiple environments, ensuring consistent deployments. AWS Elastic Beanstalk is designed for deploying applications with an automated environment, but it abstracts much of the underlying infrastructure and does not provide the same level of granular infrastructure-as-code control. AWS OpsWorks is a configuration management service using Chef and Puppet, not primarily for infrastructure provisioning. AWS CodeDeploy is for deploying application code to running instances, not for provisioning the infrastructure itself.
