An engineer says the production security group has drifted. What does this mean?
Infrastructure drift means real infrastructure no longer matches the IaC definition — typically due to manual changes or changes by other tools.

A team decides to import existing AWS resources into Terraform state. What does terraform import do?
terraform import is used to bring pre-existing resources under Terraform management without recreating them.
3 / 5
What is the risk of running terraform apply when significant state drift is present?
Applying when drift exists can cause Terraform to destroy or replace drifted resources to bring them back to the defined state — potentially disruptive.

What does state locking prevent in a team Terraform workflow?
State locking (via DynamoDB on AWS or Terraform Cloud) ensures only one operation modifies the state at a time, preventing corruption.

A colleague proposes using targeted applies (--target) to remediate drift on a specific resource. What is the risk?
terraform apply --target bypasses dependency checking. It can create inconsistencies between resources and is generally a last resort.
