• A.When you want to force Terraform to destroy a resource on the next apply
• B.When you want to force Terraform to destroy and recreate a resource on the next apply

Answer:

}

• A.The regular expression named module.web_server
• B.The output of a module named web_server
• C.By querying the AWS EC2 API to retrieve the IP address
• D.Value of the web_server parameter from the variables.tf file

Answer:
Explanation:
In a parent module, outputs of child modules are available in expressions as module. <MODULE NAME>.<OUTPUT NAME>.
For example, if a child module named web_server declared an output named instance_ip_address, you could access that value as module.web_server.instance_ip_address.

Named workspaces are not a suitable isolation mechanism for strong separation between staging and production?

• A.True
• B.False

Show Answers

Answer:
Explanation:
Organizations commonly want to create a strong separation between multiple deployments of the same infrastructure serving different development stages (e.g. staging vs. production) or different internal teams. In this case, the backend used for each deployment often belongs to that deployment, with different credentials and access controls. Named workspaces are not a suitable isolation mechanism for this scenario. https://www.terraform.io/docs/state/workspaces.html#when-to-use-multiple-workspaces

You wanted to destroy some of the dependent resources from real infrastructure. You choose to delete those resources from your configuration file and run terraform plan and then apply.
Which of the following way your resources would be destroyed?

• A.Terraform can still determine the correct order for destruction from the state even when you delete one or more items from the configuration.
• B.Those would be destroyed in the order in which they were written in the configuration file previously before you have deleted them from configuration file.
• C.The resource will be destructed in random order as you have already deleted them from configuration.
• D.You can not destroy resources by deleting them from configuration file and running plan and apply.

Show Answers

Answer:
Explanation:
Terraform typically uses the configuration to determine dependency order. However, when you delete a resource from a Terraform configuration, Terraform must know how to delete that resource. Terraform can see that a mapping exists for a resource not in your configuration and plan to destroy. However, since the configuration no longer exists, the order cannot be determined from the configuration alone.
To ensure correct operation, Terraform retains a copy of the most recent set of
dependencies within the state. Now Terraform can still determine the correct order for destruction from the state when you delete one or more items from the configuration.

During a terraform apply, a resource is successfully created but eventually fails during provisioning.
What happens to the resource?

• A.The resource will be planned for destruction and recreation upon the next terraform apply
• B.Terraform will retry to provision again.
• C.The failure of provisioner will be ignored and it will not cause a failure to terraform apply
• D.The resource will be automatically destroyed.

Show Answers

Answer:
Explanation:
If a creation-time provisioner fails, the resource is marked as tainted. A tainted resource will be planned for destruction and recreation upon the next terraform apply. Terraform does this because a failed provisioner can leave a resource in a semi-configured state. Because Terraform cannot reason about what the provisioner does, the only way to ensure proper creation of a resource is to recreate it. This is tainting.
You can change this behavior by setting the on_failure attribute, which is covered in detail below.
