During a terraform apply, a resource is successfully created but eventually fails during provisioning. What happens to the resource?

Terraform does not automatically retry resource provisioning attempts; upon failure, the resource is marked as tainted, requiring manual intervention or a subsequent apply.

Terraform does not automatically delete a resource that failed during provisioning; instead, it marks the resource as tainted so it can be re-evaluated and potentially replaced on the next apply.

Terraform does not automatically roll back an entire plan or remove all provisioned resources if a single resource's provisioner fails; only the failed resource is marked as tainted.

If a resource is successfully created but its associated provisioner fails, Terraform marks that resource as 'tainted' in the state file, signaling that it is in an inconsistent state and will be destroyed and recreated on the subsequent `terraform apply`.
