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

Rationale for Correct Answer (A):

Terraform does not automatically update state references when resource identifiers are renamed. Instead, you must use a moved block in your configuration to inform Terraform how to map the old resource to the new one. This prevents Terraform from destroying and recreating the resource.

Analysis of Incorrect Options:

B & C: Incorrect syntax — moved requires from and to.

D: Incorrect, Terraform won’t auto-detect renames and will plan to destroy and recreate the resource unless a moved block is provided.

Key Concept:

The moved block is essential for refactoring resource names without losing resources in state.

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.

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.
