Understanding Terraform Installation Methods

Which of the following is NOT a valid method to install Terraform on a Linux system?

A Installing Terraform by running 'pip install terraform' in the terminal

B Downloading the Terraform binary zip file from the official website and extracting it manually

C Installing Terraform via a Docker container image

D Using the official HashiCorp Linux package repository with apt or yum

💡 Hint

Think about the package managers and installation tools commonly used for Terraform.

Terraform is not installed via Python's pip package manager. It is distributed as a binary or through OS package managers or container images.

❓ Configuration

Verifying Terraform Installation

After installing Terraform on your system, which command will correctly display the installed Terraform version?

A terraform version check

B terraform --version

C terraform -v check

D terraform version --check

💡 Hint

Try the command that is commonly used to check version for many CLI tools.

The correct command to check Terraform version is 'terraform --version'. Other options are invalid commands and will cause errors.

Terraform Installation in a CI/CD Pipeline

You want to use Terraform in a CI/CD pipeline that runs on ephemeral Linux containers. Which approach ensures Terraform is available every time the pipeline runs without manual installation steps?

A Install Terraform manually in each pipeline run using shell commands

B Use a virtual machine with Terraform pre-installed and connect the pipeline to it

C Download Terraform binary during the first pipeline run and cache it locally on the host machine

D Use a Docker image that already includes Terraform as the pipeline environment

💡 Hint

Consider the benefits of container images for repeatable environments.

Using a Docker image with Terraform pre-installed ensures the pipeline environment always has Terraform without extra setup. Manual installs or caching add complexity or are not reliable in ephemeral containers.

❓ security

Securing Terraform Installation

Which practice improves security when installing Terraform on a production server?

A Verify the SHA256 checksum of the downloaded Terraform binary against the official HashiCorp checksum

B Download Terraform from any third-party website to get the latest version quickly

C Run Terraform as root user to avoid permission issues

D Disable TLS verification when downloading Terraform to prevent connection errors

💡 Hint

Think about how to ensure the downloaded software is authentic and untampered.

Verifying the checksum ensures the binary is exactly what HashiCorp published, preventing tampering or corruption. Downloading from untrusted sources or disabling security checks is risky.

Terraform Version Compatibility Behavior

You have Terraform version 1.4.0 installed. You run a configuration that requires version >= 1.5.0. What will happen when you run terraform init?

A Terraform will initialize successfully and ignore the version requirement

B Terraform will automatically upgrade itself to version 1.5.0

C Terraform will fail initialization with an error about incompatible Terraform version

D Terraform will prompt to downgrade the configuration to match the installed version

💡 Hint

Consider how Terraform enforces version constraints specified in configuration files.

Terraform checks the required version constraint during initialization and fails if the installed version does not meet it. It does not upgrade itself or ignore the requirement.
