28. Universal Containers (UC) decided it will not send emails to support personnel directly from Salesforce in the event that an unhandled exception occurs. Instead, UC wants an external system to be notified of the error. What is the appropriate publish/subscribe logic to meet these requirements?

Client Notifications

Explanation:

Publish/Subscribe is a system of communication between a publisher and a subscriber wherein the client subscribes to receive messages from the publisher. Client notifications is a publish/subscribe logic which enables an asynchronous system of message delivery. This means that message is sent at regular intervals. This is the case with the requirement of the Universal Containers who sends mails to support personnel from Salesforce in cases of unhandled exceptions.

Clients can book themselves on to a queue to be able to receive heads-up when there is a publication. Universal Containers can make this kind of Client notifications for an external system.
