Which configuration approach allows Terraform to manage resources across more than one provider?

• A. You cannot
• B. You must use separate configurations per provider
• C. You can configure multiple providers in the same configuration and reference them with alias
• D. Providers are configured per module only

Answer: (C)

Terraform can manage resources from different providers within a single configuration by defining multiple provider blocks and giving each one an alias. This lets you target distinct destinations (different regions, clouds, or accounts) in one workspace. You declare each provider with its own configuration and an alias, then attach resources to the correct provider by referencing that alias (for example, provider = aws.east or provider = azurerm.west). Modules can also receive a specific aliased provider via the providers meta-argument, ensuring nested resources use the intended credentials. This approach enables coordinated, cross-provider infrastructure inside one configuration rather than splitting things into separate files or runs.
