HashiCorp TERRAFORM-ASSOCIATE-003 Online Questions & Answers

• Question 101:

  When do you need to explicitly execute Terraform in refresh-only mode?

  A. Before every terraform plan.
  B. Before every terraform apply.
  C. Before every terraform import.
  D. None of the above.
  C. Before every terraform import.

  ---

  Explanation

  Purpose of Refresh-Only Mode: Running Terraform in refresh-only mode updates Terraform's state file with the current state of resources in your infrastructure without making changes to the resources themselves. Context of Terraform

  Import: When using terraform import, you're adding existing resources to the state file, and running Terraform in refresh-only mode before this operation can ensure that any initial configuration syncs precisely with the actual state.

  For more on refresh-only mode in relation to terraform import, refer to Terraform's import documentation.

• Question 102:

  What does this code do?

  

  A. Requires any version of the AWS provider > = 3.0 and < 4.0
  B. Requires any version of the AWS provider > = 3.0
  C. Requires any version of the AWS provider after the 3.0 major release like 4.1
  D. Requires any version of the AWS provider > 3.0
  A. Requires any version of the AWS provider > = 3.0 and < 4.0

  Allows only the rightmost version component to increment. For example, to allow new patch releases within a specific minor release, use the full version number: ~> 1.0.4 will allow installation of 1.0.5 and 1.0.10 but not 1.1.0

• Question 103:

  Multiple provider instances blocks for AWS can be part of a single configuration file?

  A. False
  B. True
  B. True

  ---

  Explanation

  You can optionally define multiple configurations for the same provider, and select which one to use on a per-resource or per-module basis. The primary reason for this is to support multiple regions for a cloud platform; other examples include

  targeting multiple Docker hosts, multiple Consul hosts, etc.

  To include multiple configurations for a given provider, include multiple provider blocks with the same provider name, but set the alias meta-argument to an alias name to use for each additional configuration. For example:

  # The default provider configuration

  provider "aws" {

  region = "us-east-1"

  }

  # Additional provider configuration for west coast region provider "aws" {

  alias = "west"

  region = "us-west-2"

  }

  The provider block without alias set is known as the default provider configuration. When alias is set, it creates an additional provider configuration. For providers that have no required configuration arguments, the implied empty configuration

  is considered to be the default provider configuration.

• Question 104:

  In contrast to Terraform Open Source, when working with Terraform Enterprise and Cloud Workspaces, conceptually you could think about them as completely separate working directories.

  A. True
  B. False
  A. True

  ---

  Explanation

  https://www.terraform.io/cloud-docs/workspaces "When run locally, Terraform manages each collection of infrastructure with a persistent working directory, which contains a configuration, state data, and variables. Since Terraform CLI uses content from the directory it runs in, you can organize infrastructure resources into meaningful groups by keeping their configurations in separate directories.

• Question 105:

  What feature of Terraform Cloud and/or Terraform Enterprise can you publish and maintain a set of custom modules which can be used within your organization?

  A. Terraform registry
  B. custom VCS integration
  C. private module registry
  D. remote runs
  C. private module registry

  Explanation

• Question 106:

  Which of the following does terraform apply change after you approve the execution plan? Choose two correct answers.

  A. The execution plan
  B. Terraform code
  C. Cloud infrastructure
  D. State file
  E. The .terraform directory
  C. Cloud infrastructure
  D. State file

  ---

  Explanation

  The terraform apply command changes both the cloud infrastructure and the state file after you approve the execution plan. The command creates, updates, or destroys the infrastructure resources to match the configuration. It also updates the state file to reflect the new state of the infrastructure. The .terraform directory, the execution plan, and the Terraform code are not changed by the terraform apply command.

• Question 107:

  After running into issues with Terraform, you need to enable verbose logging to assist with troubleshooting the error. Which of the following values provides the MOST verbose logging?

  A. ERROR
  B. INFO
  C. WARN
  D. TRACE
  E. DEBUG
  D. TRACE

  ---

  Explanation

  Terraform has detailed logs that can be enabled by setting the TF_LOG environment variable to any value. This will cause detailed logs to appear on stderr. You can set TF_LOG to one of the log levels TRACE, DEBUG, INFO, WARN or ERROR to change the verbosity of the logs. TRACE is the most verbose and it is the default if TF_LOG is set to something other than a log level name. Examples: export TF_LOG=DEBUG export TF_LOG=TRACE

• Question 108:

  Which of the following is not a way to trigger terraform destroy ?

  A. Passing---destroy at the end of apian request
  B. Running terraform destroy from the correct directory and then typing "yes" when prompted in the CLI
  C. Using the destroy command with auto approve
  D. Delete the state file and run terraform apply
  A. Passing---destroy at the end of apian request

  ---

  Explanation

• Question 109:

  True or False: Workspaces provide identical functionality in the open-source, Terraform Cloud, and Enterprise versions of Terraform.

  A. True
  B. False
  B. False

• Question 110:

  What are some of the problems of how infrastructure was traditionally managed before Infrastructure as Code? (select three)

  A. Requests for infrastructure or hardware required a ticket, increasing the time required to deploy applications
  B. Traditional deployment methods are not able to meet the demands of the modern business where resources tend to live days to weeks, rather than months to years
  C. Traditionally managed infrastructure can't keep up with cyclic or elastic applications
  D. Pointing and clicking in a management console is a scalable approach and reduces human error as businesses are moving to a multi-cloud deployment model
  A. Requests for infrastructure or hardware required a ticket, increasing the time required to deploy applications
  B. Traditional deployment methods are not able to meet the demands of the modern business where resources tend to live days to weeks, rather than months to years
  C. Traditionally managed infrastructure can't keep up with cyclic or elastic applications

  ---

  Explanation

  Businesses are making a transition where traditionally-managed infrastructure can no longer meet the demands of today's businesses. IT organizations are quickly adopting the public cloud, which is predominantly API-driven. To meet customer demands and save costs, application teams are architecting their applications to support a much higher level of elasticity, supporting technology like containers and public cloud resources. These resources may only live for a matter of hours; therefore the traditional method of raising a ticket to request resources is no longer a viable option Pointing and clicking in a management console is NOT scale and increases the change of human error.
