You can migrate the Terraform backend but only if there are no resources currently being managed.

1. A. False
2. B. True

Correct Answer: A
If you need to migrate to another backend, such as Terraform Cloud, so you can continue managing it. By migrating your Terraform state, you can hand off infrastructure without de-provisioning anything.

* 1. resource "aws_s3_bucket" "example" {
* 2. bucket = "my-test-s3-terraform-bucket"
* 3. …} resource "aws_iam_role" "test_role" {
* 4. name = "test_role"
* 5. …}
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?

1. A. Add explicit dependency using depends_on . This will ensure the correct order of resource creation.
2. B. This will already be taken care of by terraform native implicit dependenc
3. C. Nothing else needs to be done from your end.
4. D. 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.
5. E. 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.

Correct Answer: A
Implicit dependency works only if there is some reference of one resource to another. Explicit dependency is the option here.

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

1. A. PostgreSQL
2. B. Cassandra
3. C. MySQL
4. 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.

Correct Answer: C

What allows you to conveniently switch between multiple instances of a single configuration within its single backend?

1. A. Local backends
2. B. Providers
3. C. Remote backends
4. D. Workspaces

Correct Answer: D
Named workspaces allow conveniently switching between multiple instances of a single configuration within its single backend. ... 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.
Workspaces, allowing multiple states to be associated with a single configuration. The configuration still has only one backend, but multiple distinct instances of that configuration to be deployed without configuring a new backend or changing authentication credentials.
