Question

A company's primary data center suffers a catastrophic failure, destroying all running infrastructure. The operations team needs to rebuild the entire environment in a secondary region as quickly as possible. Their infrastructure is fully defined in Terraform configuration files stored in a Git repository. Which advantage of Infrastructure as Code most directly enables the team to recreate this environment reliably?

Accepted Answer

Repeatability, because the same configuration can be applied to provision an identical environment on demand

Answer

Cost optimization, because Terraform automatically selects the cheapest available resources during a rebuild

Answer

Manual documentation, because engineers can read the configuration files as a runbook and click through the console

Answer

State locking, because it prevents two engineers from editing the same physical server at once
