Infrastructure As Code MCQs with Answers and Explanations

Immutable infrastructure means servers are never modified after deployment. When changes are needed, new server instances are built and deployed to replace old ones. This ensures consistency, repeatability, and easier rollbacks.

Terraform uses HCL (HashiCorp Configuration Language) as its primary language for defining infrastructure. HCL is human-readable and declarative, though Terraform also supports JSON for configurations.

The "cattle, not pets" philosophy treats servers as interchangeable and disposable — when one fails, it is replaced rather than repaired. This approach supports automation, immutability, and scalability in modern DevOps.

Terraform is an open-source Infrastructure as Code tool developed by HashiCorp. It allows users to define and provision cloud and on-premises infrastructure using declarative configuration files.

IaC stands for Infrastructure as Code, a practice where infrastructure is provisioned and managed using code and automation tools like Terraform, Ansible, or CloudFormation instead of manual processes.

IaC is the practice of defining and managing infrastructure through code instead of manual configuration.

Infrastructure as Code (IaC) is the practice of managing infrastructure using machine-readable configuration files.
