The State Change Notification Service is the correct service for iSNS update notifications. True or False?

• A. True
• B. False
• C. iSCSI Change Notification Service
• D. SNS Change Notification Service

Answer: (A)

The main idea is that iSNS uses a dedicated state change mechanism to alert listeners when things in the iSNS database change. The State Change Notification Service is designed to publish events about those state changes—such as devices becoming available or unavailable, or iSCSI targets/portals changing status—so subscribers can react in real time. That makes it the correct choice for iSNS update notifications. The other names don’t correspond to the standard iSNS notification components, so they aren’t the correct mechanism for this purpose.
