Question #:1
If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform Init.
True
False
Answer: A
Explanation
If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform init3. This will ensure that you use the same provider versions across different machines and runs.
Question #:2
Which of the following command would be use to access all of the attributes and details of a resource managed by Terraform?
Terraform state show ‘ provider_type_name
Terraform state list
Terraform get provider_type_name
Terraform state list provider_type_name
Answer: A
Explanation
This is the command that you would use to access all of the attributes and details of a resource managed by Terraform, by providing the resource address as an argument. For example, terraform state show 'aws_instance.example' will show you all the information about the AWS instance named example.
Question #:3
What does terraform import do?
Imports existing resources into the state file
Imports all infrastructure from a given cloud provider
Imports a new Terraform module
Imports clean copies of tainted resources
None of the above
Answer: A
Explanation
The terraform import command is used to import existing infrastructure into your Terraform state. This command takes the existing resource and associates it with a resource defined in your Terraform configuration, updating the state file accordingly. It does not generate configuration for the resource, only the state.
Question #:4
You have a list of numbers that represents the number of free CPU cores on each virtual cluster:
What Terraform function could you use to select the largest number from the list?
top(numcpus)
max(numcpus)
ceil (numcpus)
hight[numcpus]
Answer: B
Explanation
In Terraform, the max function can be used to select the largest number from a list of numbers. The max function takes multiple arguments and returns the highest one. For the list numcpus = [18, 3, 7, 11, 2], using max(numcpus...) will return 18, which is the largest number in the list.

Terraform documentation on max function: Terraform Functions - max
Question #:5
Which of these statements about HCP Terraform/Terraform Cloud workspaces is false?
They can securely store cloud credentials.
They have role-based access controls.
C. D.
Plans and applies can be triggered via version control system integrations.
You must use the CLI to switch between workspaces.
Answer: D
Explanation
In Terraform Cloud, you can switch between workspaces using both the web UI and CLI. The statement that you "must use the CLI" is false. Workspaces can securely store cloud credentials, offer role-based access control, and integrate with VCS to trigger plan and apply operations.

Question #:6
What is the provider for the resource shown in the Exhibit?
resource "aws_vpc" "main" {
name = "test"
Answer: D
Explanation
The provider for the aws_vpc resource is aws, as the resource type begins with aws_, which denotes that it is managed by the AWS provider.

Question #:7
Which method for sharing Terraform configurations fulfills the following criteria:
1. Keeps the configurations confidential within your organization
2. Support Terraform’s semantic version constrains
3. Provides a browsable directory
Subfolder within a workspace
Generic git repository
Terraform Cloud private registry
Public Terraform module registry
Answer: C
Explanation
This is the method for sharing Terraform configurations that fulfills the following criteria:
Keeps the configurations confidential within your organization
Supports Terraform’s semantic version constraints
Provides a browsable directory
The Terraform Cloud private registry is a feature of Terraform Cloud that allows you to host and manage your own modules within your organization, and use them in your Terraform configurations with versioning and access control.
Question #:8
What is a key benefit of the Terraform state file?
A state file can schedule recurring infrastructure tasks
A state file is a source of truth for resources provisioned with Terraform
A state file is a source of truth for resources provisioned with a public cloud console
A state file is the desired state expressed by the Terraform code files
Answer: B
Explanation
This is a key benefit of the Terraform state file, as it stores and tracks the metadata and attributes of the resources that are managed by Terraform, and allows Terraform to compare the current state with the desired state expressed by your configuration files.
Question #:9
You want to define multiple data disks as nested blocks inside the resource block for a virtual machine. What Terraform feature would help you define the blocks using the values in a variable?
Local values
Count arguments
Collection functions
Dynamic blocks
Answer: D
Explanation
Dynamic blocks in Terraform allow you to define multiple nested blocks within a resource based on the values of a variable. This feature is particularly useful for scenarios where the number of nested blocks is not fixed and can change based on variable input.
Question #:10
Where in your Terraform configuration do you specify a state backend?
The resource block
The data source block
The terraform block
The provider block
Answer: C
Explanation
In Terraform, the backend configuration, which includes details about where and how state is stored, is specified within the terraform block of your configuration. This block is the correct place to define the backend type and its configuration parameters, such as the location of the state file for a local backend or the bucket details for a remote backend like S3.References = This practice is outlined in Terraform's core documentation, which provides examples and guidelines on how to configure various aspects of Terraform's behavior, including state backends .
