Salesforce Salesforce Certifications PDII Questions & Answers

• Question 11:

  Universal Containers wants to notify an external system in the event that an unhandled exception occurs when their nightly Apex batch gob runs.

  What is the appropriate publish/subscribe logic to meet this requirement?

  A. Have the external system subscribe to a standard Platform Event that gets fired with EventBus.publish().

  B. Have the external system subscribe to a custom Platform Event that gets fired with addError().

  C. Have the external system subscribe to a custom Platform Event that gets fired with EventBus.publish()

  D. Have the external system subscribe to a standard Platform Event that gets fired.

  Correct Answer: C

  According to 1, you can use Apex to publish event messages from a Salesforce app by calling the EventBus.publish method. For example, if you defined a custom platform event called Low Ink, reference this event type as Low_Ink__e. Next,

  create instances of this event, and then pass them to the Apex method.

  According to 2 and 3, you can write an after insert Apex trigger on the event object to subscribe to incoming events. Triggers provide an autosubscription mechanism in Apex. Unlike triggers on standard or custom objects, triggers on platform

  events don't execute in the same Apex transaction as the one that published the event. The trigger runs asynchronously in its own process. Therefore, using a custom Platform Event and EventBus.publish method seems to be the appropriate

  publish/subscribe logic to meet the requirement.
