Recall & Review

beginner

Why should Terraform configuration files use the .tf extension?

Terraform recognizes files with the .tf extension as configuration files. This helps Terraform load and process them correctly when running commands.

What is a good practice for naming Terraform files to keep configurations organized?

Use descriptive names that reflect the purpose, like network.tf for networking resources or variables.tf for variable definitions. This makes it easier to find and manage code.

beginner

Can you use multiple .tf files in one Terraform project folder?

Yes. Terraform automatically loads all .tf files in a folder and combines them. This allows splitting configuration into smaller, manageable parts.

Should Terraform files be named with numbers or special characters for ordering?

No. Terraform does not require numbered or special character prefixes. It processes all files together regardless of name order. Use clear descriptive names instead.

intermediate

What file extension is used for Terraform variable values and why?

Terraform uses .tfvars files to store variable values separately from configuration. This helps keep sensitive or environment-specific data organized and secure.

Which file extension should Terraform configuration files have?

A .txt

B .json

C .tf

D .conf

Terraform configuration files must have the .tf extension to be recognized and processed correctly.

How does Terraform handle multiple .tf files in the same folder?

A It ignores files with similar names

B It only loads the first file alphabetically

C It requires files to be numbered to load

D It loads and combines all .tf files automatically

Terraform automatically loads and merges all .tf files in a folder to build the full configuration.

What is a recommended naming style for Terraform files?

A Descriptive names like network.tf or variables.tf

B Random numbers like 001.tf, 002.tf

C Using spaces and special characters

D Using uppercase extensions like .TF

Descriptive names help organize and understand the purpose of each Terraform file.

Which file extension is used for storing Terraform variable values?

A .tfvars

B .tf

C .var

D .json

Terraform uses .tfvars files to separate variable values from configuration code.

Is it necessary to number Terraform files to control their load order?

A Yes, numbering controls load order

B No, Terraform loads all files together regardless of name

C Only if files are in different folders

D Yes, but only for .tfvars files

Terraform processes all .tf files in a folder together without relying on file name order.
