Terraform state rm safely removes resources from Terraform management without destruction, making B the correct choice.

Question 120

Which Terraform feature allows you to encapsulate multiple resources, accept input variables, and provide outputs for reuse across different configurations?

A) Providers

B) Modules

C) Workspaces

D) Locals

ANSWER: B) Modules

EXPLANATION

Modules are a key feature in Terraform that allow the creation of reusable, encapsulated infrastructure components with inputs and outputs, promoting maintainability, modularity, and scalability.

A) Providers
Providers define APIs and resource types Terraform can manage. They are not used for encapsulating multiple resources, handling inputs and outputs, or creating reusable infrastructure packages. A is incorrect.

B) Modules
This is the correct answer. Modules group multiple resources along with input variables and outputs into a reusable unit. They can be local, sourced from the same repository, or remote, fetched from Terraform Registry or Git repositories. Modules enable standardized infrastructure patterns, reducing code duplication and promoting consistent deployments across multiple environments. Input variables allow customization, while outputs expose key values to other modules or configurations. Nested modules facilitate complex infrastructure hierarchies, supporting large-scale deployments and multi-team collaboration. Modules also improve maintainability by centralizing logic; updates in a module propagate to all configurations that use it, reducing errors and ensuring consistency. By encapsulating resources with inputs and outputs, modules support Infrastructure as Code best practices, modular design, and scalable, reusable infrastructure deployments. They allow teams to implement consistent architecture patterns, enforce governance standards, and achieve operational efficiency, making them fundamental for advanced Terraform usage.

C) Workspaces
Workspaces provide isolated state files for multiple environments but do not encapsulate resources or provide reusable inputs and outputs. C is incorrect.

D) Locals
Locals compute intermediate values within a module for internal reuse but do not encapsulate resources or support reusable inputs and outputs. D is incorrect.

Modules encapsulate resources, support input variables, and provide outputs for reuse, making B the correct choice.
