DevOps Infrastructure as Code - Practice Questions 2026
Course Description
Mastering Infrastructure as Code (IaC) is the cornerstone of modern DevOps engineering. Whether you are working with Terraform, CloudFormation, Ansible, or Pulumi, the ability to automate environment provisioning is a high-demand skill. This course is meticulously designed to bridge the gap between theoretical knowledge and practical application through a comprehensive bank of practice exams.
Why Serious Learners Choose These Practice Exams
Serious learners understand that watching tutorials is only half the battle. To truly master DevOps IaC, you must be able to troubleshoot complex configurations and understand the "why" behind every resource declaration. Our practice exams are crafted to challenge your logic, test your attention to detail, and prepare you for the unpredictable nature of real-world production environments. By simulating the pressure of a certification or a technical interview, you build the muscle memory needed to deploy infrastructure safely and efficiently.
Course Structure
This course follows a progressive learning path, moving from fundamental syntax to complex architectural patterns.
Basics / Foundations: This section focuses on the "what" and "why" of IaC. You will be tested on the benefits of version-controlled infrastructure, idempotent operations, and the core differences between declarative and imperative approaches.
Core Concepts: Here, we dive into the essential building blocks. You will encounter questions regarding resource providers, state management, variables, and outputs. This ensures you have a solid grasp of how tools interact with cloud APIs.
Intermediate Concepts: This module introduces modularity and reusability. Expect questions on writing reusable modules, handling data sources, and managing dependencies between different infrastructure components.
Advanced Concepts: Challenge yourself with topics like state locking, remote backends, workspace management, and security best practices such as secret management and policy-as-code integration.
Real-world Scenarios: Theoretical knowledge meets reality. These questions present you with a business problem—such as scaling a multi-tier application or disaster recovery setup—and ask you to identify the best IaC implementation.
Mixed Revision / Final Test: A comprehensive simulation of a professional exam environment. This section pulls from all previous categories to ensure your knowledge is well-rounded and that you can pivot between different concepts quickly.
Sample Practice Questions
Question 1
In a Terraform-based workflow, you realize that a resource was manually deleted from the Cloud Console, but it still exists in your local state file. Which command should you run to ensure your state file reflects the actual current state of the infrastructure?
Option 1: terraform apply -auto-approve
Option 2: terraform refresh
Option 3: terraform taint
Option 4: terraform import
Option 5: terraform destroy
Correct Answer: Option 2
Correct Answer Explanation: The terraform refresh command is used to reconcile the state Terraform knows about via its state file with the real-world infrastructure. It queries the provider API and updates the state file to match.
Wrong Answers Explanation:
Option 1: This would attempt to reach the desired state defined in your code, potentially trying to recreate the resource, but it doesn't specifically focus on just updating the state file.
Option 3: Taint marks a resource for deletion and recreation during the next apply; it does not update the state to reflect reality.
Option 4: Import is used to bring existing resources under Terraform management for the first time, not to update existing tracked resources.
Option 5: This would attempt to remove all managed infrastructure, which is the opposite of reconciling state.
Question 2
You are using Ansible to configure several web servers. You want to ensure that a specific task only runs if the operating system is Ubuntu. Which keyword should you use in your task definition?
Option 1: filter
Option 2: validate
Option 3: when
Option 4: check
Option 5: loop
Correct Answer: Option 3
Correct Answer Explanation: The when clause in Ansible allows for conditional execution of tasks based on facts, variables, or the results of previous tasks.
Wrong Answers Explanation:
Option 1: Filters are used to transform data within templates or variable expressions, not for conditional task execution.
Option 2: Validate is typically used within the copy or template modules to check the syntax of a file before moving it into place.
Option 3: Check mode is a global flag to simulate a run; it is not a per-task conditional keyword.
Option 5: Loop is used for iteration over a list of items, not for conditional logic.
Question 3
Why is it considered a best practice to use a Remote Backend (such as S3 with DynamoDB locking) for IaC state files in a team environment?
Option 1: It makes the code run faster by offloading execution to the cloud.
Option 2: It prevents multiple team members from running updates simultaneously and corrupting the state.
Option 3: It automatically encrypts the source code of your infrastructure.
Option 4: It replaces the need for a Version Control System like Git.
Option 5: It allows you to write code in a GUI instead of a text editor.
Correct Answer: Option 2
Correct Answer Explanation: Remote backends support state locking (via services like DynamoDB). This ensures that only one person can modify the infrastructure at a time, preventing race conditions and state corruption.
Wrong Answers Explanation:
Option 1: Remote backends store data; they do not provide additional compute power for execution.
Option 3: While backends can encrypt the state file, they do not encrypt your actual .tf or .yml source code.
Option 4: State management is separate from versioning; you still need Git to track changes to your logic.
Option 5: Backends are storage and locking mechanisms, not code editors or graphical interfaces.
