 Outbound Message is a SOAP-based notification service that sends information about changes in Salesforce to a specified endpoint. It is a type of Remote Process Invocation—Fire and Forget integration pattern, which means that Salesforce does not wait for a response from the external system. Outbound Message can be configured using workflow rules or process builder, and it can include a subset of fields of the object that triggered the message. Outbound Message requires the external system to expose a SOAP web service that conforms to the WSDL generated by Salesforce1.

SOAP API is a way to access Salesforce dataand functionality using SOAP (Simple Object Access Protocol), which is a standard XML-based protocol for exchanging structured data over the web. SOAP API can be used for both inbound and outbound integration, and it supports two types of WSDL (Web Service Description Language) files: Enterprise and Partner. Enterprise WSDL is a strongly typedWSDL file that is specific to an organization’s Salesforce configuration. It can be used when the client application knows the objects and fields it needs to accessat compile time. Partner WSDL is a loosely typed WSDL file that is generic for any organization. It can be used when the client application needs to access data dynamically at run time2.

Therefore, the correct answer is A, because Outbound Message is suitable for Fire and Forget integration from Salesforce to the legacy system, and SOAP API using Enterprise WSDL is suitable for getting response back in a strongly typed format from the legacy system to Salesforce.

Option A is correct because using ESB (Mule) with cache/state management can help to handle the long-running requests from Salesforce and return a request ID or a response if available from the external systems. This way, Salesforce does not have to wait for the externalsystems to respond and can avoid the API gateway timeout1

Option C is correct because using Continuation callouts can make the eligibility check request from Salesforce from Lightning UI at page load without blocking the UI thread. Continuation callouts are asynchronous and can handle long-running requestsup to 60 seconds23

Option E is correct because implementing a ‘Check Update’ button that passes a requestID received from ESB can allow the user to manually check the status of the eligibility check request. This can be useful when theresponse is not available within the Continuation timeout limit or when the user wants to refresh the data4

Option B is incorrect because recommending synchronous Apex callouts from Lightning UI to External Systems via Mule and implementing polling on APIgateway timeout can cause performance issues and user frustration. Synchronous Apex callouts block the UI thread and can only handle requests up to 120 seconds. Polling on API gateway timeout can increasethe network traffic and consume the callout limits25

Option D is incorrect because creating a Platform Event in Salesforce via Remote-Call-In and using the empAPI in the lightning UI to serve 3,000 concurrent users can introduce complexity and scalability issues. Platform Events are meant for event-driven architecture and not for request-response scenarios. Remote-Call-In requires an additional license and configuration. empAPI has a limit of 1,000 concurrent subscribers per channel678

Leveraging Middleware for all back-office system integrations ensuring real time alerting, monitoring and reporting capabilities is the best integration solution for this scenario.Middleware is a software layer that acts as an intermediary between Salesforce and other systems, providing a common platform for data transformation, routing, orchestration, security, error handling, logging, and monitoring. Middleware can help to ensurereliability and performance of the integrations, as well as provide visibility and control over the integration processes. Middleware can also support various integration patterns and protocols, such as SOAP, REST, JMS, etc. Reference: Salesforce Integration Architecture Designer Resource Guide, page 14
