Terraform CloudFormation IaC Basics

1. Which key benefit does IaC provide for infrastructure management?

Version control and reproducibility of infrastructure

Elimination of all cloud costs

Automatic compliance with all security standards

Removal of the need for cloud providers

IaC enables version tracking, peer review, and consistent infrastructure deployment across environments.

Explanation

IaC enables version tracking, peer review, and consistent infrastructure deployment across environments.

2. Why is managing Terraform state carefully important?

State files contain the mapping between config and real resources; loss or corruption causes infrastructure mismanagement

State files are required to run Terraform commands

State files encrypt all sensitive data automatically

State files reduce cloud provider costs by 50%

State is critical because it tracks which real resources correspond to your configuration, enabling safe updates and deletions.

Explanation

State is critical because it tracks which real resources correspond to your configuration, enabling safe updates and deletions.

3. In CloudFormation, which section defines the actual AWS resources to create?

Resources

Parameters

Outputs

Metadata

The Resources section is mandatory in CloudFormation templates and specifies all AWS resources to be created.

Explanation

The Resources section is mandatory in CloudFormation templates and specifies all AWS resources to be created.

4. What is the purpose of a Terraform data source?

To query and reference existing infrastructure resources

To create new cloud resources

To encrypt sensitive data

To schedule automated tasks

Data sources allow Terraform to read information about existing resources without managing them.

Explanation

Data sources allow Terraform to read information about existing resources without managing them.

5. Terraform's remote backend stores state ______ to enable team collaboration.

Remote backends like S3 store state files centrally, allowing multiple team members to work on the same infrastructure safely.

Explanation

Remote backends like S3 store state files centrally, allowing multiple team members to work on the same infrastructure safely.

6. Which of these is true about CloudFormation change sets?

They preview changes before updating a stack

They permanently delete resources

They encrypt all data in transit

They limit stack size to 1 MB

Change sets allow you to review proposed stack modifications before execution, reducing risk of unintended changes.

Explanation

Change sets allow you to review proposed stack modifications before execution, reducing risk of unintended changes.

7. In Terraform, an output is used to ______ values from your infrastructure.

Outputs display important values generated by resources, making them accessible after infrastructure deployment.

Explanation

Outputs display important values generated by resources, making them accessible after infrastructure deployment.

8. What is the main difference between declarative and imperative IaC?

Declarative describes the desired state; imperative describes steps to achieve it

Imperative is faster than declarative

Declarative only works with AWS

Imperative uses JSON while declarative uses YAML

Declarative tools like Terraform let you specify what you want; imperative tools like Ansible define how to achieve it.

Explanation

Declarative tools like Terraform let you specify what you want; imperative tools like Ansible define how to achieve it.

9. CloudFormation templates use ______ to define input parameters for stacks.

Parameters allow users to provide input values when creating or updating CloudFormation stacks.

Explanation

Parameters allow users to provide input values when creating or updating CloudFormation stacks.

Submit

10. In Terraform, what is a variable?

A way to parameterize configurations for reusability

A permanent storage location for data

A type of cloud instance

A security certificate

Variables allow you to input values into Terraform configurations, making them flexible and reusable across deployments.

Explanation

Variables allow you to input values into Terraform configurations, making them flexible and reusable across deployments.

11. What is Infrastructure as Code (IaC)?

Managing infrastructure through programming and configuration files rather than manual setup

Writing Python code to replace all cloud services

A security protocol for encrypting infrastructure data

A method of storing backup copies of infrastructure

IaC treats infrastructure configuration as code, enabling version control, automation, and repeatability.

Explanation

IaC treats infrastructure configuration as code, enabling version control, automation, and repeatability.

12. What does 'terraform plan' command do?

Shows a preview of changes before applying them

Immediately applies all configuration changes

Deletes all managed resources

Encrypts the state file

The plan command generates an execution plan, showing what infrastructure changes will occur without making them.

Explanation

The plan command generates an execution plan, showing what infrastructure changes will occur without making them.

13. Terraform uses ______ as its primary configuration language.

HCL (HashiCorp Configuration Language) is Terraform's domain-specific language for defining infrastructure.

Explanation

HCL (HashiCorp Configuration Language) is Terraform's domain-specific language for defining infrastructure.

Submit

14. In CloudFormation, what is a stack?

A collection of AWS resources created from a template

A storage location for backups

A type of database service

A networking topology

A CloudFormation stack is the instantiation of a template, containing all resources defined within it.

Explanation

A CloudFormation stack is the instantiation of a template, containing all resources defined within it.

15. What is a Terraform module?

A container for reusable Terraform configurations and best practices

A security group rule in AWS

A type of encryption algorithm

A CloudFormation parameter

Modules allow you to package and reuse Terraform code, promoting consistency and reducing duplication.

Explanation

Modules allow you to package and reuse Terraform code, promoting consistency and reducing duplication.

16. Which CloudFormation template format is JSON-based and more widely supported?

YAML

JSON

HCL

XML

CloudFormation supports both JSON and YAML, but JSON is the original format with broader tool support.

Explanation

CloudFormation supports both JSON and YAML, but JSON is the original format with broader tool support.

17. In Terraform, a ______ is a single resource instance managed by your configuration.

Resources represent cloud infrastructure objects like EC2 instances, S3 buckets, or VPCs.

Explanation

Resources represent cloud infrastructure objects like EC2 instances, S3 buckets, or VPCs.

Submit

18. CloudFormation is the IaC service for which cloud provider?

Google Cloud

Microsoft Azure

Amazon Web Services (AWS)

DigitalOcean

CloudFormation is AWS's native IaC tool; other providers have equivalents like Azure Resource Manager and Google Cloud Deployment Manager.

Explanation

CloudFormation is AWS's native IaC tool; other providers have equivalents like Azure Resource Manager and Google Cloud Deployment Manager.

19. What is the primary purpose of Terraform state files?

To track the current state of managed infrastructure resources

To store encryption keys for cloud providers

To log all user authentication attempts

To compile Terraform code into machine language

State files maintain a mapping between Terraform configuration and real-world resources, enabling updates and destruction.

Explanation

State files maintain a mapping between Terraform configuration and real-world resources, enabling updates and destruction.

20. Which of these is a declarative IaC tool?

Ansible

Terraform

Chef

Puppet

Terraform uses declarative syntax where you specify the desired end state; Ansible, Chef, and Puppet are imperative tools.

Explanation

Terraform uses declarative syntax where you specify the desired end state; Ansible, Chef, and Puppet are imperative tools.
