Which command is used to initialize Vault after first starting the Vault service?
The vault operator init command initializes a Vault server. Initialization is the process by which Vault's storage backend is prepared to receive data.
This only happens once when the server is started against a new backend that has never been used with Vault before.

In order to reduce the time it takes to provision resources, Terraform uses parallelism. By default, how many resources will Terraform provision concurrently?
Terraform can limit the number of concurrent operations as Terraform walks the graph using the -parallelism=n argument. The default value for this setting is 10. This setting might be helpful if you're running into API rate limits.
After logging into the Vault UI, a user complains that they cannot enable Replication. Why would the replication configuration be missing?
Replication is not available in open-source versions of Vault. It is an enterprise feature.
True or False: Provisioners should only be used as a last resort.
Provisioners are used to execute scripts on a local or remote machine as part of resource creation or destruction. Provisioners can be used to bootstrap a resource, cleanup before destroy, run configuration management, etc. Even if the functionality you need is not available in a provider today, HashiCorp suggests that you consider local-exec usage as a temporary workaround and to open an issue in the relevant provider's repo to discuss adding first-class support.
Terraform-specific settings and behaviors are declared in which configuration block type?
The special terraform configuration block type is used to configure some behaviors of Terraform itself, such as requiring a minimum Terraform version to apply your configuration.
