Terraform and DevOps Interview Questions for Beginners | IaC, Jenkins, Git & DevSecOps

Terraform and DevOps Interview Questions for Beginners

Starting your career in Terraform, DevOps, Cloud or DevSecOps? Understanding the basic concepts is more important than memorizing tool definitions.

This beginner-friendly guide covers important interview questions from Infrastructure as Code (IaC), Terraform, Git, Jenkins, SonarQube, Artifactory, Aqua/Trivy and GitHub Actions.

Learning Approach:
Learn the concept → Understand the architecture → Practice → Explain it in an interview.

1. What is Infrastructure as Code (IaC)?

Infrastructure as Code means managing infrastructure using configuration files instead of creating cloud resources manually.

Example:

Terraform Code → Provider → Cloud Resources

Common benefits of IaC include:

• Automation
• Repeatability
• Version control
• Consistent environments
• Reduced manual configuration

2. What is Terraform?

Terraform is an Infrastructure as Code tool used to define, provision and manage infrastructure through configuration files.

A simple Terraform workflow is:

terraform init → terraform plan → terraform apply

3. What is HCL?

HCL stands for HashiCorp Configuration Language. Terraform commonly uses HCL to describe infrastructure.

resource "azurerm_resource_group" "demo" { name = "rg-demo" location = "East US" }

4. What is a Terraform Provider?

A Terraform provider allows Terraform to communicate with an external platform or service through its APIs.

Examples include:

• AzureRM Provider for Microsoft Azure
• AWS Provider for Amazon Web Services
• Google Provider for Google Cloud
• Kubernetes Provider for Kubernetes resources

5. What is a Terraform Resource?

A resource represents an infrastructure object that Terraform manages.

Examples include:

• Resource Group
• Virtual Network
• Virtual Machine
• Storage Account
• Key Vault

6. Important Terraform Commands

Command	Purpose
terraform init	Initializes the Terraform working directory
terraform plan	Shows the changes Terraform plans to make
terraform apply	Applies the planned infrastructure changes
terraform destroy	Destroys infrastructure managed by the configuration

7. What is Terraform State?

Terraform state helps Terraform keep track of the infrastructure it manages and compare the configuration with the current known state.

A common local state file is:

terraform.tfstate

In team and production environments, remote state is commonly used so that teams can manage state centrally with appropriate access control and concurrency protection.

8. What is a Terraform Variable?

Variables make Terraform configurations reusable by allowing values to be supplied instead of hard-coded.

variable "location" { type = string default = "East US" }

The same Terraform code can then be adapted for different environments such as development, testing and production. 

 

9. What is DevOps?

DevOps is a combination of practices, collaboration and automation that helps development and operations teams build, test, release and operate software more efficiently.

Plan → Code → Build → Test → Release → Deploy → Monitor

10. What is Git?

Git is a distributed version control system used to track source-code changes and support collaboration between developers and engineering teams.

A basic Git workflow is:

Clone → Branch → Code → Commit → Push → Pull Request → Merge

11. What is Jenkins?

Jenkins is an automation server commonly used to create and execute CI/CD pipelines.

A typical pipeline may look like:

Git → Jenkins → Build → Test → Security Scan → Artifact → Deploy

12. What is SonarQube?

SonarQube is used for automated code quality and code security analysis.

It can identify areas such as:

• Bugs
• Vulnerabilities
• Code smells
• Duplicated code

A CI/CD pipeline can use a SonarQube quality gate before allowing a build to continue.

13. What is Artifactory?

Artifactory is an artifact repository used to store and manage software packages and build artifacts.

Examples include:

• JAR and WAR files
• Docker images
• npm packages
• Python packages

A common DevOps approach is:

Build Once → Store Artifact → Promote Through Environments

14. What is Aqua Security / Trivy?

Aqua Security and Trivy are associated with cloud-native security and vulnerability scanning. Trivy can scan container images and other supported targets for vulnerabilities, secrets and configuration issues.

A simplified DevSecOps flow is:

Build Image → Security Scan → Security Gate → Deploy

Organizations can configure their CI/CD pipeline to stop or require review when findings meet defined security thresholds.

15. What is GitHub Actions?

GitHub Actions is a GitHub automation and CI/CD service that can execute workflows based on events such as code pushes and pull requests.

Git Push → GitHub Actions → Build → Test → Scan → Deploy

 

16. How Do These Tools Work Together?

This is one of the most useful concepts to understand for a beginner DevOps interview.

Developer

↓

Git / GitHub

↓

CI/CD Pipeline

↓

Build → Test → SonarQube → Security Scan

↓

Artifact Repository

↓

Deployment

↓

Cloud / Application Environment

↓

Monitoring

17. How Does Terraform Fit Into DevOps?

Terraform can be used to automate the infrastructure required by applications and DevOps platforms.

Git → CI/CD → Terraform Plan → Review/Approval → Terraform Apply → Cloud Infrastructure

For example, Terraform can provision resources such as virtual networks, resource groups, storage accounts, virtual machines and other supported cloud services.

18. Interview Scenario: Explain a Complete DevOps Flow

Question:

A developer pushes new code. Explain what happens from source code to deployment.

Sample answer:

Developer pushes code to Git. A CI/CD pipeline starts the build and test process. Code quality is checked using SonarQube and security scanning can be performed on dependencies or container images. The approved build artifact is stored in an artifact repository and then promoted through the required environments. Infrastructure changes can be managed using Terraform. Finally, monitoring tools are used to observe the deployed application and infrastructure.

Final Takeaway

For a beginner DevOps interview, don't focus only on memorizing definitions. Understand how the tools connect and why each tool is used.

The key idea is:

Code → Quality → Security → Artifact → Infrastructure → Deployment → Monitoring

Once you understand this flow, Terraform, Git, Jenkins, SonarQube, Artifactory, Aqua/Trivy and GitHub Actions become much easier to explain during technical interviews.
