Which of the following is a best practice for writing error messages in validation blocks?

Use technical jargon to sound professional

Include the exact value that failed validation and what is expected

Avoid mentioning the variable name

Keep the message short and vague to avoid confusion

A team manages a Kubernetes cluster with Terraform. They have a module that creates a deployment and then a service that exposes it. The service must have a stable external IP. The team wants to ensure that the service's external IP is not empty and is stable before the service is used by other resources. Which configuration should they use?

Add a `validation` block to the service resource that checks the external IP.

Add a `precondition` block to the service resource that checks the external IP before it is created.

Use a `depends_on` argument to ensure the service is created before other resources.

Add a `postcondition` block to the service resource that checks the external IP is non-empty and matches a stable pattern.
