OpenTofu Assessment: Intermediate (EN)

This assessment checks the level Intermediate. It combines conceptual questions, diagnostic cases and small design decisions.

Rules

  • Do not use production secrets.
  • Justify every answer with OpenTofu terminology.
  • Separate configuration, plan, state, backend, provider and real infrastructure.
  • Name recovery steps when you mention risky state or apply cases.
