Terraform-Associate-003 Exam Dumps - HashiCorp Certified: Terraform Associate (003) (HCTA0-003)

Sentinel is a policy-as-code framework that integrates with Terraform Cloud to enforce security, compliance, and governance rules. You can enforce rules such as approved AMIs and ensure security best practices. Policies are written in the Sentinel language, not HCL.

Terraformis written in Go, but it isdistributed as a standalone binaryanddoes notrequire the Go runtime.

Users do not need to install Go to run Terraform.

Detailed Explanation:

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.

A (✅Correct)– Providers allow Terraform tointeract with APIsof cloud/on-premises services.

B (✅Correct)– Some Terraform providers can provisionon-premises infrastructure, such as VMware, OpenStack, etc.

C (❌Incorrect)– This describesTerraform Workspaces, not providers.

D (✅Correct)– Terraform providers allow provisioning ofpublic cloud resources(AWS, Azure, GCP, etc.).

E (❌Incorrect)– Enforcing security and compliance policies isnot a direct provider function, but it can be done using Sentinel or other policy-as-code tools.

Terraform Providers

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.

The terraform import command is used to import existing infrastructure into your Terraform state. This command takes the existing resource and associates it with a resource defined in your Terraform configuration, updating the state file accordingly. It does not generate configuration for the resource, only the state.

The description argument for Terraform variables and outputs is purely for documentation purposes and isnotstored in the Terraform state file.

Terraform variables and outputs can have descriptions for readability and clarity in .tf files.

However, these descriptions are not retained in the Terraform state file.

The state file only stores actual values and references needed for resource management, not metadata such as descriptions.

Terraform detects infrastructure drift by comparing thestate filewith the actual infrastructure.

When an instance ismanually deleted, Terraformsees it as missingand marks it for recreation.

Running terraform apply willonly recreate the missing instanceswhile leaving the rest of the infrastructure unchanged.

Explanation of incorrect answers:

A (Tear down everything and rebuild)– Incorrect. Terraform does not destroy existing infrastructure unless explicitly told to.

B (Build a completely new set of infrastructure)– Incorrect. Terraform does not create duplicates unless configuration changes.

D (Stop and error out)– Incorrect. Terraform does not fail; itrebuilds missing resourcesautomatically.
