Which command lets you experiment with terraform expressions?

1. A. Terraform console
2. B. Terraform validate
3. C. Terraform env
4. D. Terraform test

Correct Answer: A
This is the command that lets you experiment with Terraform expressions, by providing an interactive console that allows you to evaluate expressions and see their results. You can use this command to test your expressions before using them in your configuration files.

Which of these commands makes your code more human readable?

1. A. Terraform validate
2. B. Terraform output
3. C. Terraform show
4. D. Terraform fmt

Correct Answer: D
The command that makes your code more human readable is terraform fmt. This command is used to rewrite Terraform configuration files to a canonical format and style, following the Terraform language style conventions and other minor adjustments for
readability. The command is optional, opinionated, and has no customization options, but it is recommended to ensure consistency of style across different Terraform codebases. Consistency can help your team understand the code more quickly and easily, making the use of terraform fmt very important. You can run this command on your configuration files before committing them to source control or as part of your CI/CD pipeline. References =

Which of the following is not a valid Terraform collection type?

1. A. Tree
2. B. Map
3. C. List
4. D. set

Correct Answer: A
This is not a valid Terraform collection type, as Terraform only supports three collection types: list, map, and set. A tree is a data structure that consists of nodes with parent-child relationships, which is not supported by Terraform.

Which is the best way to specify a tag of v1.0.0 when referencing a module stored in Git (for example.
Git::https://example.com/vpc.git)?

1. A. Append pref=v1.0.0 argument to the source path
2. B. Add version = ??1.0.0?? parameter to module block
3. C. Nothing modules stored on GitHub always default to version 1.0.0

Correct Answer: A
The best way to specify a tag of v1.0.0 when referencing a module stored in Git is to append ?ref=v1.0.0 argument to the source path. This tells Terraform to use a specific Git reference, such as a branch, tag, or commit, when fetching the module source code. For example, source = "git::https://example.com/vpc.git?ref=v1.0.0". This ensures that the module version is consistent and reproducible across different environments. References = [Module Sources], [Module Versions]

Which of the following arguments are required when declaring a Terraform output?

1. A. value
2. B. description
3. C. default
4. D. sensitive

Correct Answer: A
When declaring a Terraform output, the value argument is required. Outputs are a way to extract information from Terraform-managed infrastructure, and the value argument specifies what data will be outputted. While other arguments like description and sensitive can provide additional context or security around the output, value is the only mandatory argument needed to define an output.References = The requirement of the value argument for outputs is specified in Terraform's official documentation, which provides guidelines on defining and using outputs in Terraform configurations.
