Other certification materials providers often include outdated or removed questions by HashiCorp in their HashiCorp Terraform-Associate-003 exam. These outdated questions lead to customers failing their HashiCorp Certified: Terraform Associate (003) exam. In contrast, we ensure our questions bank includes only precise and up-to-date questions, guaranteeing their presence in your actual exam. Our main priority is your success in the HashiCorp Terraform-Associate-003 exam, not profiting from selling obsolete exam questions in PDF or Online Practice Test.
You want to define a single input variable to capture configuration values for a server. The values must represent memory as a number, and the server name as a string.
Which variable type could you use for this input?
This is the variable type that you could use for this input, as it can store multiple attributes of different types within a single value. The other options are either invalid or incorrect for this use case.
A resource block is shown in the Exhibit section of this page. How would you reference the attribute name of this resource in HCL?
Comprehensive and Detailed in-Depth
In Terraform, the correct way to reference a resource attribute is:
pgsql
CopyEdit
resource_type.resource_name.attribute
For example, if the resource block is:
hcl
CopyEdit
resource 'kubernetes_namespace' 'example' {
metadata {
name = 'my-namespace'
}
}
To reference the name attribute, use:
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 for data sources, not resources.
D (kubernetes_namespace.test.name) -- Incorrect. The resource name is 'example', not 'test'.

How can a ticket-based system slow down infrastructure provisioning and limit the ability to scale? Choose two correct answers.
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.
You're writing a Terraform configuration that needs to read input from a local file called id_rsa.pub . Which built-in Terraform function can you use to import the file's contents as a string?
To import the contents of a local file as a string in Terraform, you can use the built-in file function. By specifying file('id_rsa.pub'), Terraform reads the contents of the id_rsa.pub file and uses it as a string within your Terraform configuration. This function is particularly useful for scenarios where you need to include file data directly into your configuration, such as including an SSH public key for provisioning cloud instances.
References = This information is a standard part of Terraform's functionality with built-in functions, as outlined in Terraform's official documentation and commonly used in various Terraform configurations.
Using the terraform state rm command against a resource will destroy it.
Comprehensive and Detailed in-Depth
The terraform state rm command removes a resource from Terraform's state file but does not destroy the resource in the actual infrastructure. It only removes Terraform's knowledge of the resource, meaning Terraform will no longer manage it.
If you run terraform state rm on a resource, Terraform will forget that the resource exists.
However, the resource will still exist in the cloud or infrastructure provider.
If you later run terraform apply, Terraform may try to recreate the resource because it is no longer present in its state file.
