HashiCorp Updated Terraform-Associate-004 Exam Questions and Answers by betty

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. References = [State Locking] and [Command: validate]

Module version is optional to reference a module on the Terraform Module Registry. If you omit the version constraint, Terraform will automatically use the latest available version of the module

From the official Terraform Type Constraints Documentation:

The object({ name = string, age = number }) type expects:

name to be aquoted string, e.g. "John"

age to be anumber, e.g. 52

Option Bsatisfies both:

{

name = "John" #✅Valid string

age = 52 #✅Valid number

}

Let's analyze the incorrect ones:

❌Option A: "fifty two" is not a valid number.

❌Option C: John is unquoted (invalid string), and "fifty two" is not a number.

❌Option D: name = John is not quoted, making it an invalid string in HCL.

Terraform is strict about type and formatting. Stringsmust be quoted, and numbersmust be numeric literals.

The correct syntax to pass a variable from the root module to a child module isservers = var.num_servers. Terraform uses dot notation to reference variables.
