HashiCorp HashiCorp Certifications TA-002-P Questions & Answers

• Question 91:

  Terraform Enterprise (also referred to as pTFE) requires what type of backend database for a clustered deployment?

  A. PostgreSQL

  B. Cassandra

  C. MySQL

  D. MSSQL

  Correct Answer: A

  External Services mode stores the majority of the stateful data used by the instance in an external PostgreSQL database and an external S3-compatible endpoint or Azure blob storage. There is still critical data stored on the instance that must be managed with snapshots. Be sure to check the PostgreSQL Requirements for information that needs to be present for Terraform Enterprise to work. This option is best for users with expertise managing PostgreSQL or users that have access to managed PostgreSQL offerings like AWS RDS.

• Question 92:

  Why does this backend configuration not follow best practices?

  

  A. You should not store credentials in Terraform Configuration

  B. You should use the local enhanced storage backend whenever possible

  C. An alias meta-argument should be included in backend blocks whenever possible

  D. The backend configuration should contain multiple credentials so that more than one user can execute terraform plan and terraform apply

  Correct Answer: A

• Question 93:

  What resource dependency information is stored in Terraform's state?

  A. Only implicit dependencies are stored in state.

  B. Both implicit and explicit dependencies are stored in state.

  C. Only explicit dependencies are stored in state.

  D. No dependency information is stored in state.

  Correct Answer: B

  Terraform state captures all dependency information, both implicit and explicit. One purpose for state is to determine the proper order to destroy resources. When resources are created all of their dependency information is stored in the state. If you destroy a resource with dependencies, Terraform can still determine the correct destroy order for all other resources because the dependencies are stored in the state. https://www.terraform.io/docs/state/purpose.html#metadata

• Question 94:

  You need to write some Terraform code that adds 42 firewall rules to a security group as shown in the example.

  

  What can you use to avoid writing 42 different nested ingress config blocks by hand?

  A. A count loop

  B. A for block

  C. A for each block

  D. A dynamic block

  Correct Answer: D

  A dynamic block acts much like a for expression, but produces nested blocks instead of a complex typed value. It iterates over a given complex value, and generates a nested block for each element of that complex value. Reference: https://www.terraform.io/language/expressions/dynamic-blocks

• Question 95:

  Which of the following arguments are required when declaring a Terraform output?

  A. sensitive

  B. description

  C. default

  D. value

  Correct Answer: D

• Question 96:

  How would you reference the attribute "name* of this fictitious resource in HCL?

  

  A. resource.kubrnetes_namespace>example.name

  B. kubernetes_namespace.test.name

  C. kubernetes_namespace.example,name

  D. data kubernetes_namespace.name

  E. None of the above

  Correct Answer: C

• Question 97:

  Terraform variable names are saved in the state file.

  A. True

  B. False

  Correct Answer: B

  Terraform stores information about your infrastructure in a state file. This state file keeps track of resources created by your configuration and maps them to real-world resources. https://learn.hashicorp.com/tutorials/terraform/state-cli

• Question 98:

  In order to reduce the time it takes to provision resources, Terraform uses parallelism. By default, how many resources will Terraform provision concurrently?

  A. 5

  B. 50

  C. 10

  D. 20

  Correct Answer: C

• Question 99:

  Which feature of Terraform allows multiple state files for a single configuration file depending upon the environment?

  A. Terraform Modules

  B. Terraform Enterprise

  C. Terraform Workspaces

  D. Terraform Remote Backends

  Correct Answer: C

• Question 100:

  Any user can publish modules to the public Terraform Module Registry.

  A. True

  B. False

  Correct Answer: B
