Salesforce Integration-Architect Exam With Confidence Using Practice Dumps

Platform Events are a type of event-driven architecture that allows you to publish and subscribe to events in Salesforce and external systems. To subscribe to an event, the integration user in Salesforce needs read access to the event entity, which defines the schema and properties of the event message. To publish an event, the integration user in Salesforce needs create permission on the event entity, which is a special type of sObject that can be inserted into the platform event queue. Error handling must be performed by the remote service because the event is effectively handed off to the remote system for further processing. Salesforce does not guarantee the delivery or acknowledgment of the event by the external system. The external system should implement its own logic to handle errors, such as retrying failed events, logging errors, or sending notifications.

The integration architect should consider whether the fulfillment system can make a callback into Salesforce and whether it can implement a contract-first Outbound Messaging interface. A callback is a wayfor the fulfillment system to send a response or an acknowledgment back to Salesforce after receiving an order1. This can help ensure data consistencyand reliability between the two systems. A contract-first Outbound Messaging interface is an approach where the integration is designed based on a predefined XML schema that defines the structure and content of the messages2. This can help ensure interoperability and compatibility between the two systems. The other two questions are not relevant for the integration architect to consider. The fulfillment system does not need to create new addresses within the Order Create service, as this is a function of Salesforce3. The product catalog data does not need to be identical at all times in both systems, as long as there is a mapping or synchronization mechanism to handle any discrepancies

 Make a callout to the payment gateway through ESB supporting error handling and logging for audit purposes. This solution meets the requirements of integrating with an external RESTful service, ensuring real-time updates to the CSR, and supporting post payment processes. ESB stands for Enterprise Service Bus, which is a software architecture model that allows communication between different applications via a common bus. ESB can handle the callout to the payment gateway service, and provide error handling, logging, routing, transformation,and orchestration capabilities. ESB can also integrate with other systems or services that are involved in the post payment processes, such as billing, invoicing, or reporting.
