Correct answer: Repeatability

Repeatability is the specific IaC benefit that allows the exact same infrastructure to be provisioned multiple times in different environments or regions based on the same code definition. While idempotency ensures a single apply doesn't break things, repeatability is the strategic benefit for DR.

Correct answer: Terraform uses a provider-agnostic workflow where the core CLI handles lifecycle management, while specific Plugins (Providers) handle the API translation.

Terraform Core is cloud-agnostic and handles the workflow (Plan, Apply, State). It relies on specific Providers (plugins) to translate these lifecycle events into the specific API calls required by the target platform (AWS, Azure, etc.).

Correct answer: False

False. Terraform is declarative. The order of provisioning is determined by the dependency graph derived from implicit and explicit dependencies, not the order of the text blocks in the file.

Correct answer: It is possible by defining multiple provider blocks in the configuration and instantiating resources using those specific providers.

Terraform supports multi-cloud orchestration within a single configuration by simply defining multiple `provider` blocks (e.g., one for `aws` and one for `azurerm`). Resources are then associated with the respective providers.

Correct answer: Run `terraform init` to download the new provider plugin and update the dependency lock file.

Whenever a new provider is added or a version constraint is changed, `terraform init` must be run to download the plugin binary to the `.terraform` directory and update the `.terraform.lock.hcl` file.

Correct answer: .terraform.lock.hcl

The dependency lock file (`.terraform.lock.hcl`) records the exact versions and checksums of all providers used. Committing this file ensures that `terraform init` installs the exact same versions across all environments.
