A is incorrect because the terraform plan command will not deploy any resources at all. It will only show the changes that would be made if the terraform apply command was run. The error message in the exhibit indicates that the service principal details are invalid, which means that Terraform cannot authenticate to Azure and cannot create any resources1.

B is incorrect because you can run the terraform apply command without running the terraform plan command first. The terraform apply command will automatically generate a new plan and prompt you to approve it before applying it2. However, running the terraform plan command first can help you preview the changes and avoid any unwanted or unexpected actions.

C is correct because you must run the terraform init command once before the terraform plan command. The terraform init command initializes a working directory containing Terraform configuration files. It downloads and installs the provider plugins required for your configuration, such as the Azure provider2. It also creates a hidden directory called .terraform to store the plugin binaries and other metadata1. Without running the terraform init command, the terraform plan command will fail because it cannot find the required plugins or modules.

D is correct because the terraform plan command makes Terraform do a dry run. A dry run is a simulation of what would happen if you executed a certain action, without actually performing it. The terraform plan command creates an execution plan, which is a description of the actions that Terraform would take to make your infrastructure match your configuration2. The execution plan shows you what resources will be created, modified, or destroyed, and what attributes will be changed. The execution plan does not affect your infrastructure or state file until you apply it with the terraform apply command1.

The statement that best describes the concept of immutable infrastructure in the context of automation is:

A. It is the practice of deploying a new server for every configuration change.

Immutable Infrastructure Concept: This approach to infrastructure management involves replacing servers or components entirely rather than making changes to existing configurations once they are deployed. When a change is needed, a new server instance is provisioned with the desired configuration and the old one is decommissioned after the new one is successfully deployed and tested.

Benefits: Immutable infrastructure minimizes the risks associated with in-place updates, such as inconsistencies or failures due to configuration drift. It enhances reliability and predictability by ensuring that the deployed environment matches exactly what was tested in staging. This practice is particularly aligned with modern deployment strategies like blue/green or canary deployments.

References: The concept of immutable infrastructure is widely discussed in DevOps and cloud computing literature as a method to increase consistency and fault tolerance in automated environments.
