AWS provider Practice Test 4 — 10 Questions

Question 1

What is the purpose of the 'terraform providers lock' command?

Accepted Answer

To secure the provider versions and checksums.. It updates the .terraform.lock.hcl file to include all necessary provider checksums for the current configuration.

Answer

To encrypt the state file.

Answer

To prevent others from running init.

Answer

To download all providers.

Question 2

You have a nested module structure. How can you pass a variable from the root module through an intermediate module to a leaf module?

Accepted Answer

You must define the variable in the intermediate module and pass it to the leaf module.. Each intermediate module must define a variable and then pass it down using the 'source' or 'module' call block.

Answer

Define the variable only in the leaf module and refer to root by index.

Answer

You can use the 'global_vars' block in the root.

Answer

The intermediate module automatically inherits all root variables.

Question 3

Which THREE of these are benefits of using modules in Terraform?

Accepted Answer

Enforcing standardized configurations across teams.. Modules improve code reuse, organization, and standardization.

Answer

Increasing the execution speed of API calls.

Answer

Automatically preventing all resource drift.

Question 4

Which THREE of the following are true about 'lifecycle' blocks?

Accepted Answer

They are defined inside the resource configuration block.. They are per-resource, support specific arguments, and are defined inside the resource body.

Answer

They allow changing the provider version dynamically.

Answer

They are inherited from the provider block.

Question 5

You are designing a module that should conditionally create resources based on a boolean input. What feature should you use?

Accepted Answer

Use the 'count' meta-argument with a ternary expression.. The 'count' meta-argument is commonly used to toggle resource creation based on a boolean value.

Answer

Define multiple resources and use 'depends_on' to link them.

Answer

Use an 'if' block around the resource definition.

Answer

Use the 'module' meta-argument inside the resource.

Question 6

Which argument in a module block allows you to provide a custom name to the module instance?

Accepted Answer

The label immediately following the 'module' keyword.. The module block itself uses the label to name the instance, but the 'source' argument defines the location.

Answer

'name'

Answer

'instance_name'

Answer

'alias'

Question 7

Which TWO of the following are valid ways to pass a provider configuration to a child module?

Accepted Answer

Using the 'providers' meta-argument inside the module block.. Providers are either inherited from the root or passed explicitly using the 'providers' map in the module block.

Answer

Defining the provider inside the module's 'main.tf'.

Answer

Passing the provider as a string input variable.

Answer

Using a global variable for provider credentials.

Question 8

Which TWO of the following are true regarding variable validation in modules?

Accepted Answer

Validation blocks must return a boolean value.. Validation blocks and type constraints are the primary mechanisms for ensuring valid inputs.

Answer

Validation errors will only show during 'terraform apply'.

Answer

Validation blocks can read from other modules.

Answer

You can only validate string variables.

Question 9

You need to share a module across your entire organization. Which registry type should you use?

Accepted Answer

A private module registry in Terraform Cloud or Enterprise.. Terraform Cloud or Terraform Enterprise private module registries are the standard for internal organization-wide sharing.

Answer

The public Terraform Registry.

Answer

A shared network drive.

Answer

An S3 bucket with public read access.

Question 10

Which THREE items should be included in a well-documented Terraform module?

Accepted Answer

Clear documentation for each output.. Documentation should cover how to use the module, its inputs, and its outputs.

Answer

A list of all possible provider configurations.

Answer

The raw state file of the module's resources.
