   A team maintains a custom provider that wraps an internal REST API. The provider currently uses the Terraform Plugin SDK v2. They need to add support for a new resource type that requires streaming data from the API. The SDK v2 does not support streaming. The team must decide whether to migrate to the Plugin Framework or implement a workaround. The migration will take two weeks. The workaround involves polling the API and storing data in a local file. What is the best decision?

   • AUse a provisioner with a script to handle the streaming data.
   • BImplement the polling workaround to avoid the migration cost.
   • CUse the terraform_data resource to store the streamed data.
   • DMigrate to the Plugin Framework to properly support streaming, accepting the two-week migration cost.

   A team notices that every terraform plan and apply takes several seconds longer than expected. They suspect the provider plugin is being re-installed or re-verified on every run. What is the most likely cause?

   • AThe provider's API is slow to respond.
   • BThe provider is being recompiled from source on every run.
   • CThe plugin cache is not configured, so Terraform re-downloads the provider on each run.
   • DThe .terraform.lock.hcl file is missing, causing Terraform to re-verify checksums.

   A team is evaluating whether to write a custom provider or use a provisioner for a specific infrastructure task. They need to manage a resource that has a complex API with multiple interdependent attributes. The resource must be tracked in Terraform state and support updates. What is the recommended approach?

   • AUse the terraform_data resource type to manage the API calls.
   • BWrite a custom provider that implements the resource lifecycle (create, read, update, delete) and integrates with Terraform state.
   • CUse a local-exec provisioner with a script that calls the API and manages the resource.
   • DUse a null_resource with a remote-exec provisioner to call the API.

   A Terraform configuration uses a provider that was built with the Terraform Plugin SDK v2. The team is planning to upgrade to a version of Terraform that only supports protocol version 5.5 and later. What must they verify about the provider?

   • AThe provider's source code is written in Go version 1.20 or later.
   • BThe provider binary supports the required protocol version, which depends on the SDK version it was built with.
   • CThe provider's API endpoint supports HTTPS.
   • DThe provider is signed with a valid HashiCorp GPG key.

   In Terraform's plugin-based architecture, what is the primary role of a provider plugin?

   • AIt translates Terraform's resource declarations into API calls for a specific infrastructure platform.
   • BIt compiles Terraform configuration into executable binaries.
   • CIt stores the state of all managed resources in a remote backend.
   • DIt provides the command-line interface for running Terraform commands.
