HashiCorp HashiCorp Certifications TA-002-P Questions & Answers

• Question 11:

  Your team uses terraform OSS . You have created a number of resuable modules for important , independent network components that you want to share with your team to enhance consistency . What is the correct option/way to do that?

  A. Terraform modules cannot be shared in OSS version . Each developer needs to maintain their own modules and leverage them in the main tf file.

  B. Upload your modules with proper versioning in the terraform public module registry .Terraform OSS is directly integrated with the public module registry , and can reference the modules from the code in the main tf file.

  C. Terraform module sharing is only available in Enterprise version via terraform private module registry , so no way to enable it in OSS version.

  D. Store your modules in a NAS/ shared file server , and ask your team members to directly reference the code from there. This is the only viable option in terraform OSS ,which is better than individually maintaining module versions for every developer.

  Correct Answer: B

  Software development encourages code reuse through reusable artifacts, such as libraries, packages and modules. Most programming languages enable developers to package and publish these reusable components and make them

  available on a registry or feed. For example, Python has Python Package Index and PowerShell has PowerShell Gallery. For Terraform users, the Terraform Registry enables the distribution of Terraform modules, which are reusable

  configurations. The Terraform Registry acts as a centralized repository for module sharing, making modules easier to discover and reuse.

  The Registry is available in two variants:

  *

  Public Registry houses official Terraform providers--which are services that interact with an API to expose and manage a specific resource--and community-contributed modules.

  *

  Private Registry is available as part of the Terraform Cloud, and can host modules internally within an organization. https://www.terraform.io/docs/registry/index.html

• Question 12:

  You have configured an Auto Scaling group in AWS to automatically scale the number of instances behind a load balancer based on the instances CPU utilization. The instances are configured using a Launch Configuration. You have observed that the Auto Scaling group doesn't successfully scale when you apply changes that require replacing the Launch Configuration. Why is this happening?

  A. You need to configure an explicit dependency for the Auto Scaling group using the depends_on meta-parameter.

  B. You need to configure an explicit dependency for the Launch Configuration using the depends_on meta-parameter.

  C. You need to configure the Auto Scaling group's create_before_destroy meta-parameter.

  D. You need to configure the Launch Configuration's create_before_destroy meta-parameter.

• Question 13:

  What does Terraform use .terraform.lock.hcl file for?

  A. Tracking provider dependencies Most Voted

  B. There is no such file

  C. Preventing Terraform runs from occurring

  D. Storing references to workspaces which are locked

  Correct Answer: A

  https://www.terraform.io/language/files/dependency-lock "hcl , and this name is intended to signify that it is a lock file for various items that Terraform caches in the . terraform subdirectory of your working directory. Terraform automatically creates or updates the dependency lock file each time you run the terraform init command."

• Question 14:
