- A
Using the AWS Management Console to provision resources manually
Why wrong: Console-based provisioning is click-driven and manual — it's the opposite of IaC, which automates provisioning through code.
- B
Writing scripts to install software on EC2 instances
Why wrong: Software installation scripts are configuration management, not infrastructure as code — IaC focuses on provisioning the infrastructure itself, not configuring software within it.
- C
Defining and provisioning cloud resources using version-controlled configuration files
IaC treats infrastructure provisioning as a software engineering discipline — resources are defined in files, version-controlled in git, and applied through automated pipelines.
- D
Backing up AWS resource configurations to Amazon S3
Why wrong: Storing configuration backups is not IaC — IaC is about using code to create and manage the infrastructure itself.
Quick Answer
The correct answer is defining and provisioning cloud resources using version-controlled configuration files. This is because Infrastructure as Code, or IaC, treats your AWS infrastructure—like EC2 instances, VPCs, and S3 buckets—exactly like application code, allowing you to define it in machine-readable templates (such as AWS CloudFormation or Terraform) that are stored in a version control system like Git. This approach enables automated, repeatable deployments, peer review of changes, and easy rollback to previous states, eliminating manual, error-prone click-ops in the AWS Management Console. On the AWS Certified Cloud Practitioner CLF-C02 exam, this concept tests your understanding of how AWS enables automation and consistency; a common trap is confusing IaC with simple scripting or manual configuration, but remember the key differentiator is version control and declarative templates. Memory tip: think “Code, not Click”—if you can track it in Git, it’s IaC.
CLF-C02 Cloud Concepts Practice Question
This CLF-C02 practice question tests your understanding of cloud concepts. 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.
Which statement best describes the concept of 'infrastructure as code' (IaC) in the context of AWS?

Answer choices
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
Defining and provisioning cloud resources using version-controlled configuration files
Option C is correct because Infrastructure as Code (IaC) is the practice of defining and managing cloud resources through machine-readable definition files (e.g., AWS CloudFormation templates or Terraform HCL) that are stored in version control. This allows for automated, repeatable, and consistent provisioning of AWS infrastructure, enabling change management, peer review, and rollback capabilities.
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 confusing IaC with configuration management (e.g., installing software on instances) or manual provisioning, leading candidates to pick options that describe operational tasks rather than the core IaC practice of defining infrastructure in version-controlled files.
Detailed technical explanation
How to think about this question
Under the hood, IaC tools like AWS CloudFormation use a declarative template (JSON or YAML) that describes the desired state of resources (e.g., VPCs, subnets, EC2 instances). When you apply the template, the AWS CloudFormation service makes API calls to create, update, or delete resources to match the template, handling dependencies and rollbacks automatically. A real-world scenario is a multi-environment deployment (dev, test, prod) where the same IaC template is used with different parameter values, ensuring environments are identical and reducing configuration drift.
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 media company stores terabytes of video archives that are accessed once a year for audit purposes. Moving these objects to a cold storage tier (Azure Archive, S3 Glacier, or Google Nearline) costs a fraction of hot storage. Questions like this test whether you understand storage tiers, access frequency tradeoffs, and retrieval latency requirements.
