Exam Certified Integration Architect topic 1 question 3 discussion

Actual exam question from Salesforce's Certified Integration Architect
Question #: 3
Topic #: 1
[All Certified Integration Architect Questions]

A customer is evaluating the Platform Events solution and would like help in comparing/contrasting it with Outbound Messaging for real-time/near-real time needs. They expect 3,000 customers to view messages in Salesforce.
Which three considerations should be evaluated and highlighted when deciding between the solutions? (Choose three.)

  • A. Number of concurrent subscribers to Platform Events is capped at 2,000. An Outbound Messaging configuration can pass only 100 notifications in a single message to a SOAP end point.
  • B. Both Platform Events and Outbound Messaging offer declarative means for asynchronous near-real time needs. They aren't best suited for real-time integrations.
  • C. In both Platform Events and Outbound Messaging, the event messages are retried by and delivered in sequence, and only once. Salesforce ensures there is no duplicate message delivery.
  • D. Message sequence is possible in Outbound Messaging, but not guaranteed with Platform Events. Both offer very high reliability. Fault handling and recovery are fully handled by Salesforce.
  • E. Both Platform Events and Outbound Messaging are highly scalable. However, unlike Outbound Messaging, only Platform Events have Event Delivery and Event Publishing limits to be considered.

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)..

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
