TA-002-P Question #132: Real Exam Question with Answer & Explanation

The correct answer is C: terraform apply -var-file="testing.tfvars". To apply variable values from a custom .tfvars file, you must specify the file using the -var-file flag with the terraform apply command.

Use the Terraform CLI (terraform plan, apply, destroy, fmt, init, validate, workspace, import, taint, providers, output)

Question

You have created a custom variable definition file testing.tfvars. How will you use it for provisioning infrastructure?

Options

Aterraform apply -var-state-file ="testing.tfvars"
Bterraform plan -var-file="testing.tfvar"
Cterraform apply -var-file="testing.tfvars"
Dterraform apply var-file="testing.tfvars"

Explanation

To apply variable values from a custom .tfvars file, you must specify the file using the -var-file flag with the terraform apply command.

Common mistakes.

A. -var-state-file is not a valid Terraform CLI option for specifying a variable definition file.
B. The command terraform plan is for creating an execution plan, not applying infrastructure, and the file extension tfvar is a typo; it should be tfvars.
D. This command is syntactically incorrect as it's missing the hyphen before var-file, which is required for CLI flags.
