Module variable assignments are inherited from the parent module and you do not need to explicitly set them.
- A. False
- B. True
Answer: A
Explanation:
Explanation
Module variable assignments are not inherited from the parent module and you need to explicitly set them using the source argument. This allows you to customize the behavior of each module instance.
NEW QUESTION # 69
Variables declared within a module are accessible outside of the module.
- A. False
- B. True
Answer: A
Explanation:
Variables declared within a module are only accessible within that module, unless they are explicitly exposed as output values1.
NEW QUESTION # 70
What type of block is used to construct a collection of nested configuration blocks?
- A. Nesting
- B. repeated.
- C. For_each
- D. Dynamic
Answer: D
Explanation:
This is the type of block that is used to construct a collection of nested configuration blocks, by using a for_each argument to iterate over a collection value and generate a nested block for each element. For example, you can use a dynamic block to create multiple ingress rules for a security group resource.
NEW QUESTION # 71
What Terraform command always causes a state file to be updated with changes that might have been made outside of Terraform?
- A. Terraform plan -refresh-only
- B. Terraform plan target-state
- C. Terraform apply -lock-false
- D. Terraform show -json
Answer: A
Explanation:
Explanation
This is the command that always causes a state file to be updated with changes that might have been made outside of Terraform, as it will only refresh the state file with the current status of the real resources, without making any changes to them or creating a plan.
NEW QUESTION # 72
When should you use the force-unlock command?
- A. You see a status message that you cannot acquire the lock
- B. Automatic unlocking failed
- C. You have a high priority change
- D. apply failed due to a state lock
Answer: B
Explanation:
Explanation
You should use the force-unlock command when automatic unlocking failed. Terraform will lock your state for all operations that could write state, such as plan, apply, or destroy. This prevents others from acquiring the lock and potentially corrupting your state. State locking happens automatically on all operations that could write state and you won't see any message that it is happening. If state locking fails, Terraform will not continue. You can disable state locking for most commands with the -lock flag but it is not recommended. If acquiring the lock is taking longer than expected, Terraform will output a status message. If Terraform doesn't output a message, state locking is still occurring if your backend supports it. Terraform has a force-unlock command to manually unlock the state if unlocking failed. Be very careful with this command. If you unlock the state when someone else is holding the lock it could cause multiple writers. Force unlock should only be used to unlock your own lock in the situation where automatic unlocking failed. To protect you, the force-unlock command requires a unique lock ID. Terraform will output this lock ID if unlocking fails. This lock ID acts as a nonce, ensuring that locks and unlocks target the correct lock. The other situations are not valid reasons to use the force-unlock command. You should not use the force-unlock command if you have a high priority change, if apply failed due to a state lock, or if you see a status message that you cannot acquire the lock. These situations indicate that someone else is holding the lock and you should wait for them to finish their operation or contact them to resolve the issue. Using the force-unlock command in these cases could result in data loss or inconsistency. References = [State Locking], [Command: force-unlock]
NEW QUESTION # 73
Which of the following module source paths does not specify a remote module?
- A. Source =''[email protected]:hasicrop/example.git''
- B. Source = "module/consul''
- C. Source = ''hasicrop/consul/aws''
- D. Source = ''githhub.comicrop/example''
Answer: B
Explanation:
Explanation
The module source path that does not specify a remote module is source = "module/consul". This specifies a local module, which is a module that is stored in a subdirectory of the current working directory. The other options are all examples of remote modules, which are modules that are stored outside of the current working directory and can be accessed by various protocols, such as Git, HTTP, or the Terraform Registry. Remote modules are useful for sharing and reusing code across different configurations and environments. References = [Module Sources], [Local Paths], [Terraform Registry], [Generic Git Repository],

NEW QUESTION # 74
Terraform variable names are saved in the state file.
- A. False
- B. True
Answer: A
Explanation:
Explanation
Terraform variable names are not saved in the state file, only their values are. The state file only stores the attributes of the resources and data sources that are managed by Terraform, not the variables that are used to configure them.
NEW QUESTION # 75
You add a new provider to your configuration and immediately run terraform apply in the CD using the local backend. Why does the apply fail?
- A. Terraform needs to install the necessary plugins first
- B. Terraform needs you to format your code according to best practices first
- C. Terraform requires you to manually run terraform plan first
- D. The Terraform CD needs you to log into Terraform Cloud first
Answer: A
Explanation:
Explanation
The reason why the apply fails after adding a new provider to the configuration and immediately running terraform apply in the CD using the local backend is because Terraform needs to install the necessary plugins first. Terraform providers are plugins that Terraform uses to interact with various cloud services and other APIs. Each provider has a source address that determines where to download it from. When Terraform encounters a new provider in the configuration, it needs to run terraform init first to install the provider plugins in a local directory. Without the plugins, Terraform cannot communicate with the provider and perform the desired actions. References = [Provider Requirements], [Provider Installation]
NEW QUESTION # 76
As a developer, you want to ensure your plugins are up to date with the latest versions. Which Terraform command should you use?
- A. terraform providers -upgrade
- B. terraform init -upgrade
- C. terraform refresh -upgrade
- D. terraform apply -upgrade
Answer: B
Explanation:
This command will upgrade the plugins to the latest acceptable version within the version constraints specified in the configuration. The other commands do not have an -upgrade option.
NEW QUESTION # 77
Terraform configuration (including any module references) can contain only one Terraform provider type.
- A. False
- B. True
Answer: A
Explanation:
Terraform configuration (including any module references) can contain more than one Terraform provider type. Terraform providers are plugins that Terraform uses to interact with various cloud services and other APIs. A Terraform configuration can use multiple providers to manage resources across different platforms and services. For example, a configuration can use the AWS provider to create a virtual machine, the Cloudflare provider to manage DNS records, and the GitHub provider to create a repository. Terraform supports hundreds of providers for different use cases and scenarios. Reference = [Providers], [Provider Requirements], [Provider Configuration]
NEW QUESTION # 78
How is terraform import run?
- A. As a part of terraform refresh
- B. All of the above
- C. As a part of terraform init
- D. By an explicit call
- E. As a part of terraform plan
Answer: D
Explanation:
The terraform import command is not part of any other Terraform workflow. It must be explicitly invoked by the user with the appropriate arguments, such as the resource address and the ID of the existing infrastructure to import. Reference = [Importing Infrastructure]
NEW QUESTION # 79
Outside of the required_providers block, Terraform configurations always refer to providers by their local names.
- A. False
- B. True
Answer: A
Explanation:
Outside of the required_providers block, Terraform configurations can refer to providers by either their local names or their source addresses. The local name is a short name that can be used throughout the configuration, while the source address is a global identifier for the provider in the format registry.terraform.io/namespace/type. For example, you can use either aws or registry.terraform.io/hashicorp/aws to refer to the AWS provider.
NEW QUESTION # 80
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.vsphere_datacenter,dc
- B. Data,dc,id
- 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. Reference = [Data Source: vsphere_datacenter], [Data Source: vsphere_folder], [Expressions: Data Source Reference]
NEW QUESTION # 81
Which of these ate secure options for storing secrets for connecting to a Terraform remote backend? Choose two correct answers.
- A. A variable file
- B. Defined in Environment variables
- C. Defined in a connection configuration outside of Terraform
- D. Inside the backend block within the Terraform configuration
Answer: B,C
Explanation:
Explanation
Environment variables and connection configurations outside of Terraform are secure options for storing secrets for connecting to a Terraform remote backend. Environment variables can be used to set values for input variables that contain secrets, such as backend access keys or tokens. Terraform will read environment variables that start with TF_VAR_ and match the name of an input variable. For example, if you have an input variable called backend_token, you can set its value with the environment variable TF_VAR_backend_token1.
Connection configurations outside of Terraform are files or scripts that provide credentials or other information for Terraform to connect to a remote backend. For example, you can use a credentials file for the S3 backend2, or a shell script for the HTTP backend3. These files or scripts are not part of the Terraform configuration and can be stored securely in a separate location. The other options are not secure for storing secrets. A variable file is a file that contains values for input variables. Variable files are usually stored in the same directory as the Terraform configuration or in a version control system. This exposes the secrets to anyone who can access the files or the repository. You should not store secrets in variable files1. Inside the backend block within the Terraform configuration is where you specify the type and settings of the remote backend. The backend block is part of the Terraform configuration and is usually stored in a version control system. This exposes the secrets to anyone who can access the configuration or the repository. You should not store secrets in the backend block4. References = [Terraform Input Variables]1, [Backend Type: s3]2,

NEW QUESTION # 82
What is a key benefit of the Terraform state file?
- A. A state file can schedule recurring infrastructure tasks
- B. A state file is a source of truth for resources provisioned with Terraform
- C. A state file is the desired state expressed by the Terraform code files
- D. A state file is a source of truth for resources provisioned with a public cloud console
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.
