Question 19

- (Exam Topic 1)
Terraform validate reports syntax check errors from which of the following scenarios?

A. Code contains tabs indentation instead of spaces

B. There is missing value for a variable

C. The state files does not match the current infrastructure

D. None of the above

Correct Answer:B
The terraform validate command is used to validate the syntax of the terraform files. Terraform performs a syntax check on all the terraform files in the directory, and will display an error if any of the files doesn't validate. This command does not check formatting (e.g. tabs vs spaces, newlines, comments etc.). The following can be reported: invalid HCL syntax (e.g. missing trailing quote or equal sign) invalid HCL references (e.g. variable name or attribute which doesn't exist) same provider declared multiple times same module declared multiple times same resource declared multiple times invalid module name interpolation used in places where it's unsupported (e.g. variable, depends_on, module.source, provider) missing value for a variable (none of -var foo=... flag, -var-file=foo.vars flag, TF_VAR_foo environment variable, terraform.tfvars, or default value in the configuration) https://www.typeerror.org/docs/terraform/commands/validate

Question 20

- (Exam Topic 4)
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 21

- (Exam Topic 4)
Which type of block fetches or computes information for use elsewhere in a Terraform configuration?

A. provider

B. resource

C. local

D. data

Correct Answer:D
Data sources allow data to be fetched or computed for use elsewhere in Terraform configuration. Use of data sources allows a Terraform configuration to build on information defined outside of Terraform, or defined by another separate Terraform configuration.

Question 22

- (Exam Topic 1)
How can you trigger a run in a Terraform Cloud workspace that is connected to a Version Control System (VCS) repository?

A. Only Terraform Cloud organization owners can set workspace variables on VCS connected workspaces

B. Commit a change to the VCS working directory and branch that the Terraform Cloud workspace is connected to

C. Only members of a VCS organization can open a pull request against repositories that are connected to Terraform Cloud workspaces

D. Only Terraform Cloud organization owners can approve plans in VCS connected workspaces

Correct Answer:B
"In a workspace linked to a VCS repository, runs start automatically when you merge or commit changes to version control.
A workspace is linked to one branch of a VCS repository and ignores changes to other branches. You can specify which files and directories within your repository trigger runs. "

The terraform state command can be used to _____

A. Update current state

B. Refresh existing state file
