Intro to Terraform

Which of the following best describes a Terraform provider?​

• A container for multiple resources that are used together​

• Serves as a parameter for a Terraform module that allows a module to be customized​

• Describes an infrastructure object, such as a virtual network, compute instance, or other component​

• A plugin that Terraform uses to translate the API interactions with the service​

What happens when a terraform apply is executed?​

• Reconciles the state Terraform knows about with the real-world infrastructure​

• Creates the execution plan for the deployment of resources​

• The backend is initialized and the working directory is prepped​

• Applies the changes required in the target infrastructure in order to reach the desired configuration​

Which flag would be used within a Terraform configuration block to identify the specific version of a provider required?​

• required-provider​

• required-version​

• required_versions​

• required_providers​

True or False: You can migrate the Terraform backend but only if there are no resources currently being managed.​

• True

• False

In regards to Terraform state file, select all the statements below which are correct: (select 3)

• The state file is always encrypted at rest​

• The Terraform state can contain sensitive data, therefore the state file should be treated as sensitive​

• Storing state remotely can provide better security​

• When using local state, the state file is stored in plain-text​

• Using the mask feature, you can instruct Terraform to mask sensitive data in the state file​

Before a new provider can be used, it must be ______ (Select 2)​

• Approved by HashiCorp​

• Initialized​

• Uploaded to source control​

• Declared in the configuration​

What are some of the problems of how infrastructure was traditionally managed before Infrastructure as Code?

• Pointing and clicking in a management console isn't scalable as businesses move to a multi-cloud deployment model​

• Requests for infrastructure or hardware required a ticket, increasing the time required to deploy applications​

• Traditional deployment methods are not able to meet the demands of the modern business where resources tend to live days to weeks, rather than months to years​

• Traditionally managed infrastructure can't keep up with cyclic or elastic applications​

• All of the above

By default, where does Terraform store its state file?​

• remotely using Terraform Cloud​

• current working directory​

• shared directory​

• Amazon S3 bucket​

What happens when a terraform plan is executed?​

• It creates an execution plan and determines what changes are required to achieve the desired state in the configuration files.​

• It applies the changes required in the target infrastructure in order to reach the desired configuration​

• It reconciles the state Terraform knows about with the real-world infrastructure​

• The backend is initialized and the working directory is prepped​

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

• terraform taint​

• terrform fmt​

• terraform destroy​

• terraform refresh​
