How could change reflect in terraform without doing anything? I think A is right answer. any thoughts?

Wouldn't it be A?

https://developer.hashicorp.com/terraform/cli/commands/refresh. A should be the answer Need to run terraform plan or apply with refresh tag

"The Terraform refresh command reads the current settings from all managed remote objects and updates the Terraform state to match." Warning: This command is deprecated because its default behaviour is unsafe if you have misconfigured credentials for any of your providers. See below for more information and recommended alternatives. This won't modify your real remote objects, but it will modify the Terraform state. "You shouldn't typically need to use this command, because Terraform automatically performs the same refreshing actions as a part of creating a plan in both the Terraform plan and Terraform apply commands. This command is here primarily for backward compatibility, but we don't recommend using it because it provides no opportunity to review the effects of the operation before updating the state."

you can do terraform refresh which is a alias for terraform apply -refresh-only -auto-approve

-------------------------------

there are two ways to do this manually remove the resource using "terraform rm" from the state management and the other way is to refresh the state. Since the option given in this question is not clear enough as to run "terraform rm" or not in option C, I will go with option A is the best suited. terraform refresh

A is the best answer here terraform plan -refresh-only or terraform apply -refresh-only is best practice, but not mentioned here.

The wordings on B very unclear, while A is the closest possible answer. I would choose A over B for lack option and clarity on answers given

Due to changes in terraform versions, the answer was previously A, but is now B.

The should be B Wherever possible, avoid using 'terraform refresh' explicitly and instead rely on Terraform's behavior of automatically refreshing existing objects as part of creating a normal plan. If you don't want to automatically refresh, you can use the 'terraform apply -refresh-only' without the -auto-approve option terraform refresh is deprecated https://developer.hashicorp.com/terraform/cli/commands/refresh

A. Run terraform refresh

It seems to be A

The question is probably very old, posted at a time when option A was relevant and correct. It is however deprecated now and the suggested solution is "terraform apply -refresh-only". See https://developer.hashicorp.com/terraform/cli/commands/refresh

Chatgpt A. Run terraform refresh Yes, in older versions of Terraform (before 0.15), terraform refresh could be used to reconcile the state file with the actual infrastructure. From Terraform 0.15 and later, terraform apply performs this reconciliation. B. It will happen automatically No, Terraform does not automatically detect changes made outside of its context. You must run terraform apply (or terraform plan in older versions) to see these changes and apply them to the Terraform state file.

When you go to do anything useful (plan or apply) the state file is automatically refreshed, so the answer should be B. More a problem of the wording of the question.
