System State data includes critical system configuration and is vital for disaster recovery of which components?

• A. User documents and emails.
• B. Registry and boot files, enabling recovery of Active Directory and system configuration.
• C. Application data only.
• D. Network security policies only.

Answer: (B)

System State data covers the essential, low-level components that define how Windows boots and configures the system. The most important pieces here are the registry and the boot files, because they store the core configuration data Windows and its services rely on. When you back up and restore System State, you’re able to recover the system’s configuration and its critical services, which on a domain controller includes Active Directory data and the overall system setup. That’s why this option points to the registry and boot files as the foundational elements for disaster recovery of Active Directory and the system configuration. User data, application data, or policy files aren’t part of System State, so they aren’t the focus of this backup scope.
