Which service provides change notification when iSNS updates occur to the database and client iSCSI device changes?

• A. State Change Notification Service
• B. iSCSI Change Notification Service
• C. Drive Change Notification Service
• D. SNS Change Notification Service

Answer: (A)

State change notifications are what keep the iSNS and iSCSI subsystem in sync with real-time updates. The State Change Notification Service monitors updates to the iSNS database and changes in client iSCSI devices, then broadcasts notifications so initiators and management tools can react promptly. This lets the system know when a target is added, removed, or reconfigured, or when a client’s iSCSI device state changes, enabling timely actions like rescans or path adjustments. Other options don’t fit because they describe services that aren’t responsible for propagating iSNS/iSCSI state-change events. A distinct iSCSI-specific change notification service isn’t part of Windows in this context, and drive-related or SNS naming doesn’t apply to iSNS/iSCSI state changes.
