Question 31

- (Exam Topic 3)
Which of the below features of Terraform can be used for managing small differences between different environments which can act more like completely separate working directories.

A. Repositories

B. Workspaces

C. Environment Variables

D. Backends

Correct Answer:B
workspaces allow conveniently switching between multiple instances of a single configuration within its single backend. They are convenient in a number of situations, but cannot solve all problems.
A common use for multiple workspaces is to create a parallel, distinct copy of a set of infrastructure in order to test a set of changes before modifying the main production infrastructure. For example, a developer working on a complex set of infrastructure changes might create a new temporary workspace in order to freely experiment with changes without affecting the default workspace.
Non-default workspaces are often related to feature branches in version control. The default workspace might correspond to the "master" or "trunk" branch, which describes the intended state of production infrastructure. When a feature branch is created to develop a change, the developer of that feature might create a corresponding workspace and deploy into it a temporary "copy" of the main infrastructure so that
changes can be tested without affecting the production infrastructure. Once the change is merged and deployed to the default workspace, the test infrastructure can be destroyed and the temporary workspace deleted.

Question 34

- (Exam Topic 2)
You are using a terraform operation that writes state. Unfortunately automatic state unlocking has failed for that operation. Which of the below commands can be used to remove the already acquired lock on the state?

A. terraform unlock

B. terraform force-unlock

C. terraform state unlock

D. None of the above

Correct Answer:B
Command: force-unlock
Manually unlock the state for the defined configuration.
This will not modify your infrastructure. This command removes the lock on the state for the current configuration. The behavior of this lock is dependent on the backend being used. Local state files cannot be unlocked by another process.
https://www.terraform.io/docs/commands/force-unlock.html https://www.terraform.io/docs/state/locking.html
Terraform has a force-unlock command to manually unlock the state if unlocking failed.
If you unlock the state when someone else is holding the lock it could cause multiple writers. Force unlock should only be used to unlock your own lock in the situation where automatic unlocking failed.

Question 35

- (Exam Topic 4)
resource "aws_s3_bucket" "example" { bucket = "my-test-s3-terraform-bucket" ...} resource "aws_iam_role" "test_role" { name = "test_role" ...}
Due to the way that the application code is written , the s3 bucket must be created before the test role is created , otherwise there will be a problem. How can you ensure that?

A. This will already be taken care of by terraform native implicit dependenc

B. Nothing else needs to be done from your end.

C. Add explicit dependency using depends_on . This will ensure the correct order of resource creation.

D. Create 2 separate terraform config scripts , and run them one by one , 1 for s3 bucket , and another for IAM role , run the S3 bucket script first.

E. This is not possible to control in terraform . Terraform will take care of it in a native way , and create a dependency graph that is best suited for the parallel resource creation.

Correct Answer:B
Use the depends_on meta-argument to handle hidden resource dependencies that Terraform can't automatically infer.
Explicitly specifying a dependency is only necessary when a resource relies on some other resource's behavior but doesn't access any of that resource's data in its arguments.

Question 36

- (Exam Topic 1)
What information does the public Terraform Module Registry automatically expose about published modules?

A. Required input variables

B. Optional inputs variables and default values

C. Outputs

D. All of the above

E. None of the above

Correct Answer:D
https://www.terraform.io/registry/modules/publish
"The registry extracts information about the module from the module's source. The module name, provider, documentation, inputs/outputs, and dependencies are all parsed and available via the UI or API, as well as the same information for any submodules or examples in the module's source repository."
