The exhibit shows Action: Modify together with Replacement: True for the FortiGate EC2 resource. According to the study guide, a True replacement value means that CloudFormation will replace the existing resource with a newly created resource rather than modifying the current instance in place. Consequently, configuration that exists only locally on the original FortiGate and is not reproduced through the CloudFormation template, bootstrap configuration, or another management mechanism will not automatically exist on the replacement instance; this includes locally created users. A replacement can also introduce service interruption, so option B cannot be assumed. The replacement instance receives a different physical resource identity, making option C incorrect. The output also does not indicate that CloudFormation will roll back the existing stack before performing the update.
