Terraform uses  imperative approach to deploy infrastructure as Code.

• True

• False

Answer explanation

Terraform is an example of declarative approach to deploy infrastructure as code.

Declarative approach is more concerned about “WHAT” you want and rest is up to the software to manage and get to that desired state.

In case of imperative approach, the emphasize is more on “HOW” to get to the desired state thus system expects the steps provided by the user to be able to achieve the desired state.

“_______” are the most important element in the Terraform language wherein each block describes one or more infrastructure objects to be provisioned such as virtual network, compute instances, db instances etc

Terraform stores “_____” about your managed infrastructure and configuration which is used to map real world resources to your configuration and further created plans to make changes to your infrastructure if needed.

Answer explanation

Terraform stores "states" about your managed infrastructure and configuration which is used by Terraform to map real world resources to your configuration, keep track of metadata, and to improve performance for large infrastructures.

Statement a: Terraform state is stored by default in a local file named “terraform.tfstate”.

Statement b: Terraform  state file cannot be stored at a remote location.

• Statement a True; statement b False

• Statement a False; statement b True

• Both Statements are True

• Both Statements are False

Answer explanation

Terraform stores state file by default in a local file named "terraform.tfstate", but it can also be stored remotely.

Terraform “______” command is used to check whether the proposed changes match what you expected before you actually make the changes on to the target environment

Answer explanation

terraform plan command is basically used to generate and show an execution plan

==> Terraform plan –out test.tfplan
