Exam Certified Integration Architect topic 1 question 3 discussion

I would consider A, B, & E to be the correct answers. C is not correct; outbound messages are queued and retried multiple times D is not correct; platform event recovery is not handled by Salesforce; it's up to the remote system to use replay IDs to retrieve messages are within the recovery window (24 hours or 72 hours, depending on event type).

ABE for me. The challenge is chosing between B & D. I would prefer B over D because D- is not totally correct wrt fault handling. Salesforce doesnt provide complere fault handling & recovery. If the message is subscribed successfully by the consumer, but is failed therafter , its lost. So consumer has to handle it. B - near real time is right considering the PE and OM both uses Queue in between making them Async. Only Pure Sync transactional callouts ( REST AND SOAP ) are considered strictly Real time ( But for all practical purposes we used PE for real time)..

ABE looks correct

ADE is the answer

B is also incorrect because Platform Events are suited to real-time integrations https://www.salesforceben.com/salesforce-platform-events/

C is incorrect because Outbound Messages may be delivered more than once and out of order. https://help.salesforce.com/s/articleView?id=sf.workflow_om_considerations.htm&type=5

A- Platform Event: Maximum number of concurrent CometD clients (subscribers) per platform event channel or across all platform event channels = 2000 Outbound Message: A single SOAP message can include up to 100 notifications. D- Platform Event: A subscriber can retrieve events at any time and isn’t restricted to listening to events at the time they’re sent. https://developer.salesforce.com/docs/atlas.en-us.214.0.platform_events.meta/platform_events/platform_events_api_considerations.htm Outboud Message: Messages are queued until they are sent, to preserve message reliability. E Platform Event: Maximum number of event notifications published per hour = 100000

C is incorrect because order of execution is not guaranteed in both cases https://developer.salesforce.com/docs/atlas.en-us.214.0.platform_events.meta/platform_events/platform_event_limits.htm https://help.salesforce.com/s/articleView?id=sf.workflow_om_considerations.htm&type=5
