Detailed Explanation:
Rationale for Correct Answer: Infrastructure as Code (IaC) focuses on defining and managing infrastructure using configuration files and automation, rather than manual processes. While IaC provides benefits like automation, reusability, and version control, it does not inherently provide a GUI. In fact, IaC is typically CLI- driven and code-centric, which is the opposite of relying on graphical interfaces.
Analysis of Incorrect Options (Distractors):
A). Reusability of code Incorrect because IaC enables reusable modules and templates, which is a key benefit.
B). Automation Incorrect because IaC automates infrastructure provisioning and management.
D). Versioning Incorrect because IaC configurations can be stored in version control systems (e.g., Git), enabling tracking and rollback.
Key Concept: IaC emphasizes automation, consistency, reusability, and version control, not graphical interfaces.

Rationale for Correct Answer (False):
Any user with access to the saved plan file (terraform plan -out=planfile) can run terraform apply planfile.
Terraform does not enforce user-specific restrictions.
Analysis of Incorrect Option:
True: Incorrect - Terraform doesn't tie plan files to individual users.
Key Concept:
Plan files ensure predictability but are not bound to the identity of the user.

terraform init is the first command that should be run after writing a new Terraform configuration or cloning an existing one from version control. It initializes a working directory containing Terraform configuration files and downloads any required providers and modules. The other commands are used for different purposes, such as importing existing resources, switching between workspaces, generating execution plans, etc.

Detailed Explanation:
* Rationale for Correct Answer: The configuration uses a data block, not a resource block. In Terraform, a data block reads information about existing infrastructure from a provider. It does not create, update, or delete infrastructure. This data source searches for an existing AWS EC2 instance with the tag Name
= web.
* Analysis of Incorrect Options (Distractors):
* A. True. Incorrect. A new AWS instance would be created using a resource block such as resource " aws_instance " " web " { ... }, not a data source.
* Key Concept: Terraform data blocks are used to query existing infrastructure, while resource blocks manage infrastructure lifecycle.

A module can declare a variable with a default value without requiring the caller to define it. This allows the module to provide a sensible default behavior that can be customized by the caller if needed. References =
