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 looks correct

https://developer.salesforce.com/docs/atlas.en-us.platform_events.meta/platform_events/platform_event_limits.htm

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
