Your manager has instructed you to start using terraform for the entire infra provisioning of the application stack. There are 4 environments - DEV , QA , UAT , and PROD. The application team has asked for complete segregation between these environments including the backend , state , and also configurations ,since there will be unique resources in different environments . What is the possible way to structure the terraform code to facilitate that.

• A.Completely separate the working directories , keep one for each environment . For each working directory , maintain a separate configuration file , variables file , and map to a different backend.
• B.Completely separate the working directories , keep one for each environment . For each working directory , maintain a separate configuration file , variables file , and map to the same backend.
• C.Implement terraform workspaces , and map each environment with one workspace.
• D.Enable remote backend storage . Configure 4 different backend storages , one for each environment.

• A.source = "git::https://example.com/my_test_module.git#tag=v1.0.4"
• B.source = "git::https://example.com/my_test_module.git&ref=v1.0.4"
• C.source = "git::https://example.com/my_test_module.git?ref=v1.0.4"

Your developers are facing a lot of problem while writing complex expressions involving difficult interpolations . They have to run the terraform plan every time and check whether there are errors , and also check terraform apply to print the value as a temporary output for debugging purposes. What should be done to avoid this?

• A.Use terraform console command to have an interactive UI with full access to the underlying terraform state to run your interpolations , and debug at real-time.
• B.Add a breakpoint in your code, using the watch keyword , and output the value to console for temporary debugging.
• C.Use terraform zipmap function , it will be able to easily do the interpolations without complex code.
• D.Use terraform console command to have an interactive UI , but you can only use it with local state , and it does not work with remote state.
