HashiCorp HashiCorp Certifications TA-002-P Questions & Answers

• Question 131:

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

  A. False

  B. True

  Correct Answer: B

  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 132:

  When do you need to explicitly execute terraform refresh?

  A. Before every terraform plan

  B. Before every terraform apply

  C. Before every terraform import

  D. None of the above

  Correct Answer: D

  Wherever possible, avoid using terraform refresh explicitly and instead rely on Terraform's behavior of automatically refreshing existing objects as part of creating a normal plan. Source: https://www.terraform.io/cli/commands/refresh

• Question 133:

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

  A. True

  B. False

  Correct Answer: B

  Reference: https://www.terraform.io/language/values/outputs

• Question 134:

  Given the Terraform configuration below, in which order will the resources be created?

  A. Larger image

  B. resources will be created simultaneously

  C. aws_eip will be created first aws_instance will be created second

  D. aws_instance will be created first aws_eip will be created second

  Correct Answer: D

  The aws_instance will be created first, and then aws_eip will be created second due to the aws_eip's resource dependency of the aws_instance id

• Question 135:

  A junior admin accidentally deleted some of your cloud instances. What does Terraform do when you run terraform apply?

  A. Build a completely brand new set of infrastructure

  B. Tear down the entire workspace infrastructure and rebuild it

  C. Rebuild only the instances that were deleted Most Voted

  D. Stop and generate an error message about the missing instances

  Correct Answer: C

• Question 136:

  How would you be able to reference an attribute from the vsphere_datacenter data source for use with the argument within the vsprere_folder resource in the following configuration?

  

  A. vsphere_datacenter.dc.id

  B. data.vsphere_datacenter.dc

  C. data.dc,id

  D. data.vsphere_datacenter.dc.id

  Correct Answer: D

• Question 137:

  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

  Correct Answer: C

• Question 138:

  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

  Correct Answer: ABC

  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.

• Question 139:

  When you use a remote backend that needs authentication. HashrCorp recommends that you:

  A. Push your Tefraform configuration to an encrypted git repository

  B. Write the authentication credentials in the Terraform configuration files

  C. Use partial configuration to load the authentication credentials outside of the Terraform code

  D. Keep the Terraform configuration files in a secret store

  Correct Answer: C

  We recommend omitting the token from the configuration, and instead using terraform login or manually configuring credentials in the CLI config file. Reference: https://www.terraform.io/language/settings/backends/remote

• Question 140:

  When using parent/child modules to deploy infrastructure, how would you export a value from one module to import into another module.

  For example, a module dynamically deploys an application instance or virtual machine, and you need the IP address in another module to configure a related DNS record in order to reach the newly deployed application.

  A. Export the value using terraform export and input the value using terraform input.

  B. Configure the pertinent provider's configuration with a list of possible IP addresses to use.

  C. Configure an output value in the application module in order to use that value for the DNS module.

  D. Preconfigure the IP address as a parameter in the DNS module.

  Correct Answer: C

  Output values are like the return values of a Terraform module, and have several uses:

  *

  A child module can use outputs to expose a subset of its resource attributes to a parent module.

  *

  A root module can use outputs to print certain values in the CLI output after running terraform apply.

  *

  When using remote state, root module outputs can be accessed by other configurations via a terraform_remote_state data source. https://www.terraform.io/docs/configuration/outputs.html
