  Correct Answer: CDE

  tonumber and tostring are Type Conversion function https://www.terraform.io/docs/configuration/functions.html

• Question 292:

  You have a Terraform configuration file where a variable itemNum is defined as follows:

  variable "itemNum" { default = 3}

  You also have a defined the following environment variables in your shell: TF_itemNum =6, TF_VAR_itemNum =9. You also have a terraform.tfvars file with the following contents

  itemNum = 7

  When you run the following apply command, what is the value assigned to the itemNum variable?

  terraform apply-var itemNum =4

  A. 10

  B. 6

  C. 1

  D. 4

  E. 3

  Correct Answer: D

  The-var and-var-file methods of assigning variables have the highest precedence. https://www.terraform.io/docs/configuration/variables.html

• Question 293:

  You have already set TF_LOG = DEBUG to enable debug log. Now you want to always write the log to the directory you're currently running terraform from. what should you do to achieve this.

  A. Run the command export TF_LOG_FILE=./terraform.log.

  B. Run the command export TF_LOG_PATH=./terraform.log.

  C. Run the command export TF_DEBUG_PATH=./terraform.log.

  D. No explicit action required. Terraform will take care of this as you have enable TF_LOG.

  Correct Answer: B

• Question 294:

  Which of the following best describes a Terraform provider?

  A. A plugin that Terraform uses to translate the API interactions with the service or provider.

  B. Serves as a parameter for a Terraform module that allows a module to be customized.

  C. Describes an infrastructure object, such as a virtual network, compute instance, or other components.

  D. A container for multiple resources that are used together.

  Correct Answer: A

  A provider is responsible for understanding API interactions and exposing resources. Providers generally are an IaaS (e.g. Alibaba Cloud, AWS, GCP, Microsoft Azure, OpenStack), PaaS (e.g. Heroku), or SaaS services (e.g. Terraform Cloud, DNSimple, Cloudflare). https://www.terraform.io/docs/providers/index.html

• Question 295:

  If you delete a remote backend from the configuration, will you need to rebuild your state files locally?

  A. False

  B. True

  Correct Answer: A

  You can change your backend configuration at any time. You can change both the configuration itself as well as the type of backend (for example from "consul" to "s3"). Terraform will automatically detect any changes in your configuration and request a reinitialization. As part of the reinitialization process, Terraform will ask if you'd like to migrate your existing state to the new configuration. This allows you to easily switch from one backend to another. https://www.terraform.io/docs/backends/config.html#changing-configuration

• Question 296:

  Which of the below are paid features of Terraform Cloud?

  A. Full API Coverage

  B. Secure variable Storage

  C. Roles/ Team management

  D. Cost Estimation

  E. Private Module Registry

  F. Sentinel policies

• Question 297:

  You want terraform plan and apply to be executed in Terraform Cloud's run environment but the output is to be streamed locally. Which one of the below you will choose?

  A. Local Backends

  B. This can be done using any of the local or remote backends

  C. Remote Backends

  D. Terraform Backends

  Correct Answer: C

  The remote backend stores Terraform state and may be used to run operations in Terraform Cloud.

  When using full remote operations, operations like terraform plan or terraform apply can be executed in Terraform Cloud's run environment, with log output streaming to the local terminal.

  Remote plans and applies use variable values from the associated Terraform Cloud workspace.

• Question 298:

  By default, a defined provisioner is a creation-time provisioner.

  A. True

  B. False

  Correct Answer: A

  https://www.terraform.io/docs/provisioners/index.html

• Question 299:

  What is the standard workflow that a developer follows while working with terraform open source version?

  A. Run terraform refresh to update the terraform state , then write the terraform code , and finally run terraform apply.

  B. Run terraform destroy first since you need to start from fresh every time , before running terraform apply.

  C. Write terraform code , and run terraform push , to update the terraform state to the remote repo , which in turn will take care of the next steps.

  D. Write the terraform code on the developer machine , run terraform plan to check the changes , and run terraform apply to provision the infra.

  Correct Answer: D

  You do not need to run terraform refresh as terraform plan implicitly will run terraform refresh. https://www.terraform.io/guides/core-workflow.html

• Question 300:

  You do not need to specify every required argument in the backend configuration. Omitting certain arguments may be desirable to avoid storing secrets, such as access keys, within the main configuration. When some or all of the arguments are omitted, we call this a _____________.

  A. First Time Configuration

  B. Default Configuration

  C. Changing Configuration

  D. Partial Configuration

  E. Incomplete Configuration

  Correct Answer: D

  You do not need to specify every required argument in the backend configuration. Omitting certain arguments may be desirable to avoid storing secrets, such as access keys, within the main configuration. When some or all of the arguments

  are omitted, we call this a partial configuration.

  With a partial configuration, the remaining configuration arguments must be provided as part of the initialization process. There are several ways to supply the remaining arguments:

  *

  Interactively: Terraform will interactively ask you for the required values, unless interactive input is disabled. Terraform will not prompt for optional values.

  *

  File: A configuration file may be specified via the init command line. To specify a file, use the-backend-config=PATH option when running terraform init. If the file contains secrets it may be kept in a secure data store, such as Vault, in which case it must be downloaded to the local disk before running Terraform.

  *

  Command-line key/value pairs: Key/value pairs can be specified via the init command line. Note that many shells retain command-line flags in a history file, so this isn't recommended for secrets. To specify a single key/value pair, use the-backend-config="KEY=VALUE" option when running terraform init. https://www.terraform.io/docs/backends/config.html#partial-configuration
