NEW QUESTION # 74
Which are forbidden actions when the terraform state file is locked? Choose three correct answers.
- A. Terraform apply
- B. Terraform destroy
- C. Terraform state list
- D. Terraform for
- E. Terraform validate
- F. Terraform validate
Answer: A,B,F
Explanation:
The terraform state file is locked when a Terraform operation that could write state is in progress. This prevents concurrent state operations that could corrupt the state. The forbidden actions when the state file is locked are those that could write state, such as terraform apply, terraform destroy, terraform refresh, terraform taint, terraform untaint, terraform import, and terraform state *. The terraform validate command is also forbidden, because it requires an initialized working directory with the state file. The allowed actions when the state file is locked are those that only read state, such as terraform plan, terraform show, terraform output, and terraform console. Reference = [State Locking] and [Command: validate]
NEW QUESTION # 75
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. top(numcpus)
- C. max(numcpus)
- D. hight[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.

NEW QUESTION # 76
terraform init creates an example main.tf file in the current directory.
- A. True
- B. False
Answer: B
Explanation:
Comprehensive and Detailed in-Depth Explanation:terraform initdoes not create a main.tf file.
* Itinitializesthe Terraform working directory, downloads provider plugins, and configures the backend.
* Terraform does not generate an example configuration (main.tf); users must create it manually.

NEW QUESTION # 77
Why does this backend configuration not follow best practices?
- A. You should not store credentials in Terraform configuration
- B. You should use the local enhanced storage backend whenever possible
- C. An alias meta-argument should be included in backend blocks whenever possible
- D. The backend configuration should contain multiple credentials so that more than one user can execute terraform plan and terraform apply
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.

pgsql
CopyEdit
kubernetes_namespace.example.name
Explanation of incorrect answers:
* A (resource.kubernetes_namespace.example.name)- Incorrect. Terraform does not use the resource.
prefix when referencing resources.
* C (data.kubernetes.namespace.name)- Incorrect. This syntax is used fordata sources, not resources.
* D (kubernetes_namespace.test.name)- Incorrect. The resource name is "example", not "test".

- A. terraform apply
- B. terraform plan
- C. terraform destroy
- D. terraform state list
Answer: D
Explanation:
* terraform state listonly displays resources stored in the state filebut doesnot interact with the cloud provideror refresh the state.
* terraform plan, terraform apply, and terraform destroycompare or modify the infrastructure, so theyrefresh the stateto ensure accuracy.

NEW QUESTION # 80
Which of the following arguments are required when declaring a Terraform output?
- A. value
- B. default
- C. sensitive
- D. description
Answer: A
Explanation:
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.
Reference = 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.
NEW QUESTION # 81
How can a ticket-based system slow down infrastructure provisioning and limit the ability to scale? Choose two correct answers.
- A. Ticket based systems generate a full audit trail of the request and fulfillment process
- B. The more resources your organization needs, the more tickets your infrastructure team has to process
- C. End-users have to request infrastructure changes
- D. Users can access catalog of approved resources from drop down list in a request form
Answer: C
Explanation:
These are some of the ways that a ticket-based system can slow down infrastructure provisioning and limit the ability to scale, as they introduce delays, bottlenecks, and manual interventions in the process of creating and modifying infrastructure.
NEW QUESTION # 82
What is the purpose of the terraform.lock.hcl file in Terraform?
- A. There is no such file.
- B. Preventing Terraform runs from occurring.
- C. Tracking specific provider dependencies.
- D. Storing references to workspaces, which are locked.
Answer: C
Explanation:
Detailed Explanation:
* Rationale for Correct Answer (D):The terraform.lock.hcl file is automatically created and maintained by Terraform. It records the specific versions and checksums of providers used in a configuration, ensuring consistent runs across environments and machines.
* Analysis of Incorrect Options:
* A. There is no such file: Incorrect - the lock file exists and is crucial for dependency management.
* B. Storing references to workspaces: Incorrect - workspaces are tracked in the state file, not the lock file.
* C. Preventing Terraform runs: Incorrect - the lock file does not block runs; it enforces consistent provider versions.
* Key Concept:The terraform.lock.hcl file enforces provider version consistency, which is critical for reproducible and reliable Terraform deployments.

NEW QUESTION # 84
Terraform configuration can only import modules from the public registry.
- A. True
- B. False
Answer: B
Explanation:
Terraform configuration can import modules from various sources, not only from the public registry. Modules can be sourced from local file paths, Git repositories, HTTP URLs, Mercurial repositories, S3 buckets, and GCS buckets. Terraform supports a number of common conventions and syntaxes for specifying module sources, as documented in the [Module Sources] page. Reference = [Module Sources]
NEW QUESTION # 85
Where does the Terraform local backend store its state?
- A. In the terraform file
- B. In the /tmp directory
- C. In the terraform,tfstate file
- D. In the user's terraform,state file
Answer: C
Explanation:
Explanation
This is where the Terraform local backend stores its state, by default, unless you specify a different file name or location in your configuration. The local backend is the simplest backend type that stores the state file on your local disk.
NEW QUESTION # 86
You can reference a resource created with for_each using a Splat ( *) expression.
- A. True
- B. False
Answer: B
Explanation:
Explanation
You cannot reference a resource created with for_each using a splat (*) expression, as it will not work with resources that have non-numeric keys. You need to use a for expression instead to iterate over the resource instances.
NEW QUESTION # 87
Terraform variable names are saved in the state file.
- A. True
- B. False
Answer: B
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 # 88
How would you output returned values from a child module in the Terraform CLI output?
- A. Declare the output in the root configuration
- B. Declare the output in the child module
- C. Declare the output in both the root and child module
- D. None of the above
Answer: C
Explanation:
To output returned values from a child module in the Terraform CLI output, you need to declare the output in both the child module and the root module. The child module output will return the value to the root module, and the root module output will display the value in the CLI. References = [Terraform Outputs]
