D) The subscription automatically encrypts all messages Answer: B Explanation: Non‑durable subscriptions receive messages only while the subscriber is active; messages are not stored persistently. Question 31. Which step type is most appropriate for converting a string date “2023‑ 07 ‑ 15 ” to a Date object within a flow? A) MAP using pub.string:toDate B) INVOKE with a custom Java class only C) BRANCH with a date comparison D) EXIT with a formatted string Answer: A Explanation: pub.string:toDate converts a string representation into a Date pipeline variable.
