Which command would you use to check for discrepancies between the actual infrastructure and your Terraform configuration?

• A. terraform plan
• B. terraform apply
• C. terraform show
• D. terraform update

Answer: (A)

The command used to check for discrepancies between the actual infrastructure and your Terraform configuration is "terraform plan." This command analyzes the current state of infrastructure and compares it with the configuration files defined in your Terraform code. It previews the changes required to align the live infrastructure with the desired state without making any actual modifications. When "terraform plan" runs, it provides a summary of what Terraform would do if you were to apply those changes, allowing you to review and confirm the actions before executing them. This ensures that you are aware of any additions, deletions, or modifications that would occur, thereby preventing unintended changes to your infrastructure. The other commands serve different purposes: "terraform apply" actually applies the changes specified in the plan, updating the infrastructure; "terraform show" displays information about the current state or the contents of the configuration; and "terraform update" is not a valid command in Terraform, as it does not exist in the context of managing infrastructure. Thus, "terraform plan" is the correct command for reviewing discrepancies.
