Northern Trail Outfitters (NTO) has recently implemented middleware for orchestration of services across platforms.

Answer A is valid because the Remote Process Invocation fire and forget pattern allows sending a message from Salesforceto the ERP system without waiting for a response or acknowledgement. This enables near real-time integration and reduces the latency and complexity of the integration. The Flow Builder is a low code tool that can be used to invoke an Apex actionthat makes the HTTP callout to the REST endpoint on insert of the order object12

Answer C is valid because the Change Data Capture feature allows capturing changes in Salesforce data and publishing them as eventsto a streaming channel. The middleware can subscribe to the channel and receive the events that contain the order details. The replay Id is a unique identifier for each event that can be used by the middleware to resume from the last processed event in case of failures or interruptions. This ensures reliable and consistent integration between Salesforce and the ERP system3

Answer B is not valid because the Outbound Messaging feature uses SOAP messages to send notifications to external systems based on workflow rules. This requires configuring a SOAP endpoint and a WSDL file for the ERP system, which may not be compatible with the REST endpoint requirement. Moreover, Outbound Messaging does not guarantee delivery or order of messages, which may affect the accuracy and timeliness of the integration.

Answer D is not valid because the Platform Event feature allows publishing custom events from Salesforce to external systems or vice versa using a publish/subscribe model. However, this requires creating a platform event object and defining its fields and permissions, which may notbe a low code solution. Moreover, using the record type as the platform event name may not be a valid or meaningful option, as record types are used to define different business processes or user interfaces for an object.
