You add a new resource to an existing Terraform configuration, but do not update the version constraint in the configuration. The existing and new resources use the same provider. The working contains a .terraform.lock, hc1 file.
How will Terraform choose which version of the provider to use?

1. A. Terraform will use the version recorded in your lock file
2. B. Terraform will use the latest version of the provider for the new resource and the version recorded in the lock file to manage existing resources
3. C. Terraform will check your state file to determine the provider version to use
4. D. Terraform will use the latest version of the provider available at the time you provision your new resource

Correct Answer: A
This is how Terraform chooses which version of the provider to use, when you add a new resource to an existing Terraform configuration, but do not update the version constraint in the configuration. The lock file records the exact version of each provider that was installed in your working directory, and ensures that Terraform will always use the same provider versions until you run terraform init -upgrade to update them.

The _____ determines how Terraform creates, updates, or delete resources.

1. A. Terraform configuration
2. B. Terraform provisioner
3. C. Terraform provider
4. D. Terraform core

Correct Answer: C
This is what determines how Terraform creates, updates, or deletes resources, as it is responsible for understanding API interactions with some service and exposing resources and data sources based on that API.

A Terraform output that sets the "sensitive" argument to true will not store that value in the state file.

1. A. True
2. B. False

Correct Answer: A
A Terraform output that sets the "sensitive" argument to true will store that value in the state file. The purpose of setting sensitive = true is to prevent the value from being displayed in the CLI output during terraform plan and terraform apply, and to mask it in the Terraform UI. However, it does not affect the storage of the value in the state file. Sensitive outputs are still written to the state file to ensure that Terraform can manage resources correctly during subsequent operations.

A module can always refer to all variables declared in its parent module.

1. A. True
2. B. False

Correct Answer: B
A module cannot always refer to all variables declared in its parent module, as it needs to explicitly declare input variables and assign values to them from the parent module??s arguments. A module cannot access the parent module??s variables directly, unless they are passed as input arguments.

If a DevOps team adopts AWS CloudFormation as their standardized method for provisioning public cloud resoruces, which of the following scenarios poses a challenge for this team?

1. A. The team is asked to manage a new application stack built on AWS-native services
2. B. The organization decides to expand into Azure wishes to deploy new infrastructure
3. C. The team is asked to build a reusable code based that can deploy resources into any AWS region
4. D. The DevOps team is tasked with automating a manual, web console-based provisioning.

Correct Answer: B
This is the scenario that poses a challenge for this team, if they adopt AWS CloudFormation as their standardized method for provisioning public cloud resources, as CloudFormation only supports AWS services and resources, and cannot be used to provision infrastructure on other cloud platforms such as Azure.
