Question 1

- (Exam Topic 4)
What is a downside to using the Vault provider to read secrets from Vault?

A. Secrets are persisted to the state file and plans.

B. Terraform and Vault must be running on the same version.

C. Terraform and Vault must be running on the same physical host.

D. Terraform requires a unique auth method to work with Vault.

Correct Answer:A
The Vault provider allows Terraform to read from, write to, and configure Hashicorp Vault.
Interacting with Vault from Terraform causes any secrets that you read and write to be persisted in both Terraform's state file and in any generated plan files. For any Terraform module that reads or writes Vault secrets, these files should be treated as sensitive and protected accordingly.

Question 2

- (Exam Topic 4)
Which of the following locations can Terraform use as a private source for modules? (Choose two.)

A. Internally hosted SCM (Source Control Manager) platform

B. Public Terraform Module Registry

C. Private repository on GitHub

D. Public repository on GitHub

Correct Answer:AC

Question 3

- (Exam Topic 4)
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.

What kind of configuration block will create an infrastructure object with settings specified in the block?

Correct Answer:C

Question 5

- (Exam Topic 3)
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

Correct Answer:D
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 6

- (Exam Topic 1)
Which of the following is allowed as a Terraform variable name?

A. count

B. name

C. source

D. version

Correct Answer:B
"The name of a variable can be any valid identifier except the following: source, version, providers, count, for_each, lifecycle, depends_on, locals." https://www.terraform.io/language/values/variables
