Question: What triggers the sending of `notifyIRPInfoChanges` to subscribed IRPManager instances in an Entry Point (EP) Integration Reference Point (IRP) scenario?
Option 1: Periodic synchronization between EPIRP instances
Option 2: Addition or modification of IRP information via standardized interfaces
Option 3: Removal of an EPIRP instance from the operating environment
Option 4: Changes to IRP information (e.g., management scope, IRP Reference) stored in EPIRP, including initial entry via non-standardized local interfaces
Explanation: The correct answer is Option 4 because `notifyIRPInfoChanges` is sent when there are changes to the information of one IRP (including itself and other EPIRP instances) stored in EPIRP, encompassing updates and initial entry through non-standardized local interfaces upon installation.
