   A team is configuring a Google Cloud environment. They have a service account (google_service_account "sa") and a bucket (google_storage_bucket "bucket"). The bucket's IAM policy must grant access to the service account's email. Which configuration correctly creates an implicit dependency so the service account is created before the IAM policy?

   • ACreate the IAM policy in a separate terraform apply run after the service account is created.
   • BUse a variable for the service account email and pass it to the IAM policy resource.
   • CIn the google_service_account resource, set depends_on = [google_storage_bucket_iam_policy.bucket_iam].
   • DIn the google_storage_bucket_iam_policy resource, set member = "serviceAccount:${google_service_account.sa.email}".

   In which scenario would you need to use depends_on to ensure proper resource ordering?

   • AWhen resources are in different modules
   • BWhen a resource must be created after another resource, but its configuration does not reference any attribute of that resource
   • CWhen a resource references an attribute of another resource
   • DWhen resources use the same provider

   A team manages a multi-tier application. The database (aws_db_instance "db") is created first, then the application server (aws_instance "app"), and finally the load balancer (aws_lb "lb"). The application server references the database endpoint. The load balancer has depends_on = [aws_instance.app]. During a terraform apply, the team notices that the load balancer is created after the application server, but the application server is sometimes created before the database. What is the most likely cause?

   • AThe application server references the database endpoint through a variable, so the implicit dependency is lost.
   • BThe load balancer's depends_on on the application server forces the app server to be created before the database.
   • CThe application server uses a data source to look up the database endpoint.
   • DThe database resource is in a different module, so dependencies are not tracked.

   A developer has two resources: aws_instance "app" and aws_eip "eip". The EIP is associated with the instance using aws_eip_association "eip_assoc" with instance_id = aws_instance.app.id. The developer wants to ensure the EIP is created before the association. Which statement is true?

   • AThe association implicitly depends on both the instance and the EIP because it references the instance ID and the EIP's allocation ID.
   • BThe EIP must be created before the instance because the association references both.
   • CThe developer must add depends_on = [aws_eip.eip] to the association because the EIP is not referenced.
   • DThe association only depends on the instance because it references the instance ID, not the EIP.
