Adaface Sample Terraform Questions

Given the following Terraform code:

What would be the value of the extra_security_group_id output when create_security_group is set to true, project_environment is set to "staging", and enable_additional_security_group is set to false?

Consider the following Terraform code:

Which statement is true about this Terraform code?
            
            A. The code creates an EC2 instance and assigns an EIP to it within a VPC.
            B. The code creates an EC2 instance, but it is not associated with the specified security group.
            C. The code creates an EC2 instance and an EIP, but does not associate the EIP with the instance.
            D. The code creates a security group that allows SSH access to the EC2 instance from anywhere.
            E. The code creates an EC2 instance with the specified security group, but does not assign an EIP to it.

Consider the following Terraform code snippet, which represents a simplified infrastructure for a web application:

In the above code, a security group (`web`) and a web server (`web`) are being created. An Elastic IP (`web`) is also being created and associated with the web server. The `web` Elastic IP has a lifecycle policy that prevents it from being destroyed.
            
            Which of the following statements is true?

A: The Elastic IP (`web`) will not be associated with the `web` instance if the security group fails to create.
            B: The Elastic IP (`web`) can be disassociated manually in the AWS console without affecting the Terraform state.
            C: The Elastic IP (`web`) will be released when the `web` instance is destroyed.
            D: A Terraform destroy operation will fail due to the lifecycle policy of the `web` Elastic IP.
            E: The `web` instance must be manually terminated before the security group can be deleted.

Consider the following Terraform code snippet:

This code creates a Google Compute Engine instance and uses a local-exec provisioner to print a message when the instance is created. It also has a lifecycle block that sets create_before_destroy to true.
            
            What will happen if you update the machine_type parameter for the google_compute_instance resource and execute terraform apply?

A: Terraform will fail to apply the changes due to the create_before_destroy lifecycle rule.
            
            B: Terraform will destroy the existing instance, create a new one, and the provisioner will print the message once.
            
            C: Terraform will create a new instance before destroying the old one, and the provisioner will print the message twice.
            
            D: Terraform will update the existing instance without creating a new one or destroying the old one, and the provisioner will print the message once.
            
            E: Terraform will create a new instance before destroying the old one, but the provisioner will print the message only once.
