The Terraform state file stores the attributes of all managed resources. When outputs are not defined, the most direct way to inspect these attributes is by using the terraform state subcommands. The terraform state list command will display the addresses of all resources in the current state. Once the specific resource address is identified, terraform state show can be used to print all of its attributes, including the public IP address, directly from the state file. This is a non-destructive, read-only operation designed for state inspection.

A. Using terraformremotestate requires writing a new configuration, which is not a quick method for simply viewing an attribute of an existing resource.

C. The terraform output command only works if an output block has been explicitly defined in the configuration, which the scenario states was not done.

D. This is a destructive and slow process. It would destroy the existing resource and create a new one, which would have a different public IP address.

state list command: "The terraform state list command is used to list resources within a Terraform state." This supports the first step of identifying the resource.

state show command: "The terraform state show command is used to show the attributes of a single resource in the Terraform state... This command can be useful for inspecting the current state of a resource." This confirms it is the correct tool for viewing the resource's attributes like an IP address.

Output Values: "The terraform output command is used to extract the value of an output variable from the state file." This implies an output must first be defined in the configuration.

terraformremotestate Data Source: "The terraformremotestate data source allows you to use the root-level outputs of another Terraform configuration as input data." This shows its purpose is for sharing data between configurations
