How do you specify a module??s version when publishing it to the public terraform Module Registry?

1. A. Configuration it in the module's Terraform code
2. B. Mention it on the module's configuration page on the Terraform Module Registry
3. C. The Terraform Module Registry does not support versioning modules
4. D. Tag a release in the associated repo

Correct Answer: D
This is how you specify a module??s version when publishing it to the public Terraform Module Registry, as it uses the tags from your version control system (such as GitHub or GitLab) to identify module versions. You need to use semantic versioning for your tags, such as v1.0.0.

terraform plan updates your state file.

1. A. True
2. B. False

Correct Answer: B
The terraform plan command does not update the state file. Instead, it reads the current state and the configuration files to determine what changes would be made to bring the real-world infrastructure into the desired state defined in the configuration. The plan operation is a read-only operation and does not modify the state or the infrastructure. It is the terraform apply command that actually applies changes and updates the state file.References = Terraform's official guidelines and documentation clarify the purpose of the terraform plan command, highlighting its role in preparing and showing an execution plan without making any changes to the actual state or infrastructure .

How could you reference an attribute from the vsphere_datacenter data source for use with the datacenter_id argument within the vsphere_folder resource in the following configuration?

1. A. Data.vsphere_datacenter.DC.id
2. B. Vsphere_datacenter.dc.id
3. C. Data,dc,id
4. D. Data.vsphere_datacenter,dc

Correct Answer: A
The correct way to reference an attribute from the vsphere_datacenter data source for use with the datacenter_id argument within the vsphere_folder resource in the following configuration is data.vsphere_datacenter.dc.id. This follows the syntax for accessing data source attributes, which is data.TYPE.NAME.ATTRIBUTE. In this case, the data source type is vsphere_datacenter, the data source name is dc, and the attribute we want to access is id. The other options are incorrect because they either use the wrong syntax, the wrong punctuation, or the wrong case. References = [Data Source: vsphere_datacenter], [Data Source: vsphere_folder], [Expressions: Data Source References]

If a module declares a variable with a default, that variable must also be defined within the module.

1. A. True
2. B. False

Correct Answer: B
A module can declare a variable with a default value without requiring the caller to define it. This allows the module to provide a sensible default behavior that can be customized by the caller if needed. References = [Module Variables]

You have created a main.tf Terraform configuration consisting of an application server, a database and a load balanced. You ran terraform apply and Terraform created all of the resources successfully.
Now you realize that you do not actually need the load balancer, so you run terraform destroy without any flags. What will happen?

1. A. Terraform will prompt you to pick which resource you want to destroy
2. B. Terraform will destroy the application server because it is listed first in the code
3. C. Terraform will prompt you to confirm that you want to destroy all the infrastructure
4. D. Terraform will destroy the main, tf file
5. E. Terraform will immediately destroy all the infrastructure

Correct Answer: C
This is what will happen if you run terraform destroy without any flags, as it will attempt to delete all the resources that are associated with your current working directory or workspace. You can use the -target flag to specify a particular resource that you want to destroy.
