Complete Terraform-Associate-003 HashiCorp Materials

Detailed Explanation:

Rationale for Correct Answer (C):Credentials should not be hardcoded in Terraform files. Best practice is to configure them via environment variables or secret managers.

Analysis of Incorrect Options:

A: Shared servers introduce risk and drift.

B: Storing secrets in config/version control is insecure.

D: Incorrect since option C is valid.

Key Concept:Separation of credentials from code is a Terraform security best practice.

The required_providers block is used to specify the provider versions that the configuration can work with. The version argument accepts a version constraint string, which must be enclosed in double quotes. The version constraint string can use operators such as >=, ~>, =, etc. to specify the minimum, maximum, or exact version of the provider. For example, version = ">= 3.1" means that theconfiguration can work with any provider version that is 3.1 or higher. References = [Provider Requirements] and [Version Constraints]

Detailed Explanation:

Rationale for Correct Answer (True):A cloud block in Terraform configuration specifies a single Terraform Cloud or HCP Terraform workspace. You cannot use one cloud block for multiple workspaces.

Analysis of Incorrect Option:

False: Incorrect because a cloud block is a one-to-one mapping with a single workspace.

Key Concept:Cloud blocks manage remote operations and backend configuration tied to one workspace.

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.
