Salesforce Certified Platform Developer II — Question 208

Instead of waiting to send emails to support personnel directly from the finish method of a batch Apex process, Universal Containers wants to notify an external system in the event that an unhandled exception occurs.

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

Answer options

• A. Publish the error event using the addError() method and write a trigger to subscribe to the event and notify the external system.
• B. Publish the error event using the addError() method and have the external system subscribe to the event using CometD.
• C. Publish the error event using the Eventbus.publish() method and have the external system subscribe to the event using CometD.
• D. No publishing is necessary. Have the external system subscribe to the BatchApexErrorEvent.

Correct answer: D

Explanation

The correct answer is D because the external system can directly subscribe to the BatchApexErrorEvent without the need for additional publishing. Options A, B, and C incorrectly suggest using addError() or Eventbus.publish(), which are not necessary in this context since the external system can directly listen for the error events.
