All standard backend types support state locking, and remote operations like plan, apply, and destroy.

1. A. True
2. B. False

Correct Answer: B
Not all standard backend types support state locking and remote operations like plan, apply, and destroy. For example, the local backend does not support remote operations and state locking. State locking is a feature that ensures that no two users can make changes to the state file at the same time, which is crucial for preventing race conditions. Remote operations allow running Terraform commands on a remote server, which is supported by some backends like remote or consul, but not all.

You have created a main.tf Terraform configuration consisting of an application server, a database and a load balanced. You ran terraform apply and Terraform created all of the resources successfully.
Now you realize that you do not actually need the load balancer, so you run terraform destroy without any flags. What will happen?

1. A. Terraform will prompt you to pick which resource you want to destroy
2. B. Terraform will destroy the application server because it is listed first in the code
3. C. Terraform will prompt you to confirm that you want to destroy all the infrastructure
4. D. Terraform will destroy the main, tf file
5. E. Terraform will immediately destroy all the infrastructure

Correct Answer: C
This is what will happen if you run terraform destroy without any flags, as it will attempt to delete all the resources that are associated with your current working directory or workspace. You can use the -target flag to specify a particular resource that you want to destroy.
