QUESTION: 117

Provisioners should only be used as a last resort.

False
True

Answer(s): B

Explanation:

Provisioners are a Last Resort
Terraform includes the concept of provisioners as a measure of pragmatism, knowing that there will always be certain behaviors that can't be directly represented in Terraform's declarative model.
However, they also add a considerable amount of complexity and uncertainty to Terraform usage. Firstly, Terraform cannot model the actions of provisioners as part of a plan because they can in principle take any action. Secondly, successful use of provisioners requires coordinating many more details than Terraform usage usually requires: direct network access to your servers, issuing Terraform credentials to log in, making sure that all of the necessary external software is installed, etc.
The following sections describe some situations which can be solved with provisioners in principle, but where better solutions are also available. We do not recommend using provisioners for any of the use-cases described in the following sections.
Even if your specific use-case is not described in the following sections, we still recommend attempting to solve it using other techniques first, and use provisioners only if there is no other option.

QUESTION: 118

Which Terraform command will force a marked resource to be destroyed and recreated on the next apply?

terraform fmt
terraform destroy
terraform taint
terraform refresh

Answer(s): C

Explanation:

The terraform taint command manually marks a Terraform-managed resource as tainted, forcing it to be destroyed and recreated on the next apply.
This command will not modify infrastructure, but does modify the state file in order to mark a resource as tainted. Once a resource is marked as tainted, the next plan will show that the resource will be destroyed and recreated and the next apply will implement this change.
Forcing the recreation of a resource is useful when you want a certain side effect of recreation that is not visible in the attributes of a resource. For example: re-running provisioners will cause the node to be different or rebooting the machine from a base image will cause new startup scripts to run.
Note that tainting a resource for recreation may affect resources that depend on the newly tainted resource. For example, a DNS resource that uses the IP address of a server may need to be modified to reflect the potentially new IP address of a tainted server. The plan command will show this if this is the case.

QUESTION: 119

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

Local backends
Providers
Remote backends
Workspaces

Answer(s): D

Explanation:

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. https://www.terraform.io/docs/state/workspaces.html

QUESTION: 120

terraform refresh will update the state file?

True
False

Answer(s): A

Explanation:

The terraform refresh command is used to reconcile the state Terraform knows about (via its state file) with the real-world infrastructure. This can be used to detect any drift from the last-known state, and to update the state file.
This does not modify infrastructure, but does modify the state file. If the state is changed, this may cause changes to occur during the next plan or apply.
