NEW QUESTION # 50
Which two steps are required to provision new infrastructure in the Terraform workflow? Choose two correct answers.
- A. Import
- B. Alidate
- C. Plan
- D. apply
- E. Init
Answer: D,E
Explanation:
Explanation
The two steps that are required to provision new infrastructure in the Terraform workflow are init and apply.
The terraform init command initializes a working directory containing Terraform configuration files. It downloads and installs the provider plugins that are needed for the configuration, and prepares the backend for storing the state. The terraform apply command applies the changes required to reach the desired state of the configuration, as described by the resource definitions in the configuration files. It shows a plan of the proposed changes and asks for confirmation before making any changes to the infrastructure. References =

NEW QUESTION # 52
What are some benefits of using Sentinel with Terraform Cloud/Terraform Cloud? Choose three correct answers.
- A. You can restrict specific resource configurations, such as disallowing the use of CIDR=0.0.0.0/0.
- B. Policy-as-code can enforce security best practices
- C. You can enforce a list of approved AWS AMIs
- D. Sentinel Policies can be written in HashiCorp Configuration Language (HCL)
- E. You can check out and check in cloud access keys
Answer: A,B,C
Explanation:
Sentinel is a policy-as-code framework that allows you to define and enforce rules on your Terraform configurations, states, and plans1. Some of the benefits of using Sentinel with Terraform Cloud/Terraform Enterprise are:
* You can restrict specific resource configurations, such as disallowing the use of CIDR=0.0.0.0/0, which would open up your network to the entire internet. This can help you prevent misconfigurations or security vulnerabilities in your infrastructure2.
* Policy-as-code can enforce security best practices, such as requiring encryption, authentication, or compliance standards. This can help you protect your data and meet regulatory requirements3.
* You can enforce a list of approved AWS AMIs, which are pre-configured images that contain the operating system and software you need to run your applications. This can help you ensure consistency, reliability, and performance across your infrastructure4.

NEW QUESTION # 54
How could you reference an attribute from the vsphere_datacenter data source for use with the datacenter_id argument within the vsphere_folder resource in the following configuration?
- A. Data,dc,id
- B. Data.vsphere_datacenter,dc
- C. Data.vsphere_datacenter.DC.id
- D. Vsphere_datacenter.dc.id
Answer: C
Explanation:
The correct way to reference an attribute from the vsphere_datacenter data source for use with the datacenter_id argument within the vsphere_folder resource in the following configuration is data.
vsphere_datacenter.dc.id. This follows the syntax for accessing data source attributes, which is data.TYPE.
NAME.ATTRIBUTE. In this case, the data source type is vsphere_datacenter, the data source name is dc, and the attribute we want to access is id. The other options are incorrect because they either use the wrong syntax, the wrong punctuation, or the wrong case. References = [Data Source: vsphere_datacenter], [Data Source:
vsphere_folder], [Expressions: Data Source References]
NEW QUESTION # 55
Which option cannot be used to keep secrets out of Terraform configuration files?
- A. secure string
- B. A -var flag
- C. Environment variables
- D. A Terraform provider
Answer: A
Explanation:
A secure string is not a valid option to keep secrets out of Terraform configuration files. A secure string is a feature of AWS Systems Manager Parameter Store that allows you to store sensitive data encrypted with a KMS key. However, Terraform does not support secure strings natively and requires a custom data source to retrieve them. The other options are valid ways to keep secrets out of Terraform configuration files. A Terraform provider can expose secrets as data sources that can be referenced in the configuration. Environment variables can be used to set values for input variables that contain secrets. A -var flag can be used to pass values for input variables that contain secrets from the command line or a file. Reference = [AWS Systems Manager Parameter Store], [Terraform AWS Provider Issue #55], [Terraform Providers], [Terraform Input Variables]
NEW QUESTION # 56
What is the provider for this resource?
- A. aws
- B. Main
- C. Vpc
- D. Test
Answer: A
Explanation:
In the given Terraform configuration snippet:
resource "aws_vpc" "main" {
name = "test"
}
The provider for the resource aws_vpc is aws. The provider is specified by the prefix of the resource type. In this case, aws_vpc indicates that the resource type vpc is provided by the aws provider.

Terraform documentation on providers: Terraform Providers
NEW QUESTION # 57
You ate creating a Terraform configuration which needs to make use of multiple providers, one for AWS and one for Datadog. Which of the following provider blocks would allow you to do this?
- A.
- B.
- C.
- D.
Answer: A
Explanation:
Option C is the correct way to configure multiple providers in a Terraform configuration. Each provider block must have a name attribute that specifies which provider it configures2. The other options are either missing the name attribute or using an invalid syntax.
NEW QUESTION # 58
What does terraform import do?
- A. Imports existing resources into the state file
- B. Imports all infrastructure from a given cloud provider
- C. None of the above
- D. Imports clean copies of tainted resources
- E. Imports a new Terraform module
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.
NEW QUESTION # 59
Before you can use a new backend or HCP Terraform/Terraform Cloud integration, you must first execute terraform init.

NEW QUESTION # 63
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?
- A. ceil (numcpus)
- B. hight[numcpus]
- C. max(numcpus)
- D. top(numcpus)
Answer: C
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.

What is a key benefit of the Terraform state file?
- A. A state file is a source of truth for resources provisioned with Terraform
- B. A state file is the desired state expressed by the Terraform code files
- C. A state file can schedule recurring infrastructure tasks
- D. A state file is a source of truth for resources provisioned with a public cloud console
Answer: A
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.
NEW QUESTION # 65
You have multiple team members collaborating on infrastructure as code (IaC) using Terraform, and want to apply formatting standards for readability.
How can you format Terraform HCL (HashiCorp Configuration Language) code according to standard Terraform style convention?
- A. Designate one person in each team to review and format everyone's code
- B. Write a shell script to transform Terraform files using tools such as AWK, Python, and sed
- C. Run the terraform fmt command during the code linting phase of your CI/CD process Most Voted
- D. Manually apply two spaces indentation and align equal sign "=" characters in every Terraform file (*.tf)
Answer: C
Explanation:
Explanation
The terraform fmt command is used to rewrite Terraform configuration files to a canonical format and style.
This command applies a subset of the Terraform language style conventions, along with other minor adjustments for readability. Running this command on your configuration files before committing them to source control can help ensure consistency of style between different Terraform codebases, and can also make diffs easier to read. You can also use the -check and -diff options to check if the files are formatted and display the formatting changes respectively2. Running the terraform fmt command during the code linting phase of your CI/CD process can help automate this process and enforce the formatting standards for your team. References = [Command: fmt]2

NEW QUESTION # 67
What value does the Terraform Cloud private registry provide over the public Terraform Module Registry?
- A. The ability to share modules with public Terraform users and members of Terraform Cloud Organizations
- B. The ability to share modules publicly with any user of Terraform
- C. The ability to tag modules by version or release
- D. The ability to restrict modules to members of Terraform Cloud or Enterprise organizations
Answer: D
Explanation:
Explanation
The Terraform Cloud private registry provides the ability to restrict modules to members of Terraform Cloud or Enterprise organizations. This allows you to share modules within your organization without exposing them to the public. The private registry also supports importing modules from your private VCS repositories. The public Terraform Module Registry, on the other hand, publishes modules from public Git repositories and makes them available to any user of Terraform. References = : Private Registry - Terraform Cloud : Terraform Registry - Provider Documentation
NEW QUESTION # 68
Which Terraform collection type should you use to store key/value pairs?
- A. Set
- B. Tuple
- C. list
- D. Map
Answer: D
Explanation:
The Terraform collection type that should be used to store key/value pairs is map. A map is a collection of values that are accessed by arbitrary labels, called keys. The keys and values can be of any type, but the keys must be unique within a map. For example, var = { key1 = "value1", key2 = "value2" } is a map with two key/value pairs. Maps are useful for grouping related values together, such as configuration options or metadata. Reference = [Collection Types], [Map Type Constraints]
NEW QUESTION # 69
You ate making changes to existing Terraform code to add some new infrastructure. When is the best time to run terraform validate?
- A. Before you run terraform apply so you can validate your provider credentials
- B. Before you run terraform plan so you can validate your code syntax
- C. After you run terraform apply so you can validate your infrastructure
- D. After you run terraform plan so you can validate that your state file is consistent with your infrastructure
Answer: B
Explanation:
This is the best time to run terraform validate, as it will check your code for syntax errors, typos, and missing arguments before you attempt to create a plan. The other options are either incorrect or unnecessary.
NEW QUESTION # 70
If you update the version constraint in your Terraform configuration, Terraform will update your lock file the next time you run terraform Init.
- A. True
- B. 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.
NEW QUESTION # 71
What does this code do?
- A. Requires any version of the AWS provider > = 3.0 and <4.0
- B. Requires any version of the AWS provider > = 3.0 major release. like 4.1
- C. Requires any version of the AWS provider >= 3.0
- D. Requires any version of the AWS provider > 3.0
Answer: A
Explanation:
This is what this code does, by using the pessimistic constraint operator (~>), which specifies an acceptable range of versions for a provider or module.
NEW QUESTION # 72
The public Terraform Module Registry is free to use.
- A. True
- B. False
Answer: A
Explanation:
Explanation
The public Terraform Module Registry is free to use, as it is a public service that hosts thousands of self-contained packages called modules that are used to provision infrastructure. You can browse, use, and publish modules to the registry without any cost.
NEW QUESTION # 73
Why does this backend configuration not follow best practices?
- A. You should not store credentials in Terraform configuration
- B. An alias meta-argument should be included in backend blocks whenever possible
- C. The backend configuration should contain multiple credentials so that more than one user can execute terraform plan and terraform apply
- D. You should use the local enhanced storage backend whenever possible
Answer: A
Explanation:
Explanation
This is a bad practice, as it exposes your credentials to anyone who can access your configuration files or state files. You should use environment variables, credential files, or other mechanisms to provide credentials to Terraform.
NEW QUESTION # 74
When you include a module block in your configuration that references a module from the Terraform Registry, the "version" attribute is required.
- A. True
- B. False
Answer: B
Explanation:
The "version" attribute is optional when referencing a module from the Terraform Registry. If not specified, the latest version will be used, but it is often recommended to specify a version to ensure consistency across environments.
