A company uses Customer Community for course registration. The payment gateway takes more than 30 seconds to process transactions. Students want results in real time to retry if errors occur. What is the recommended integration approach?

• A. Use Continuation to process payment to the payment gateway
• B. Use Request and Reply to make an API call to the payment gateway.
• C. Use Platform Events to process payment to the payment gateway.

An enterprise architect has requested the Salesforce integration architect to review the following (see diagram and description) and provide recommendations after carefully considering all constraints of the enterprise systems and Salesforce Platform limits.
About 3,000 phone sales agents use a Salesforce Lightning user interface (UI) concurrently to check eligibility of a customer for a qualifying offer.
There are multiple eligibility systems that provide this service and are hosted externally.
However, their current response times could take up to 90 seconds to process and return (there are discussions to reduce the response times in the future, but no commitments are made).
These eligibility systems can be accessed through APIs orchestrated via ESB (MuleSoft).
All requests from Salesforce will have to traverse through the customer's API Gateway layer, and the API Gateway imposes a constraint of timing out requests after 9 seconds.

Which recommendation should the integration architect make?

• A. Use Continuation callouts to make the eligibility check request from Salesforce Lightning UI at page load.
• B. Recommend synchronous Apex callouts from Lightning UI to External Systems via Mule and implement polling on an API Gateway timeout.
• C. Create a platform event in Salesforce via Remote Call-In and use the empAPI in the Lightning UI to serve 3,000 concurrent users when responses are received by Mule.

Northern Trail Outfitters has recently implemented middleware for orchestration of services across platforms. The Enterprise Resource Planning (ERP) system being used requires transactions be captured near real-time at a REST endpoint initiated in Salesforce when creating an Order object. Additionally, the Salesforce team has limited development resources and requires a low-code solution. Which option should fulfill the use case requirements?12

• A. Use Remote Process Invocation Fire and Forget pattern on insert on the Order object using Flow Builder.
• B. Implement a Workflow Rule wi5th Outbound Messaging to send SOAP messages to the designated endpoint.
• C. Implement Change Data Capture on the Order object and leverage the replay ID in the middleware solution.

A company needs to integrate a legacy on-premise application that can only support SOAP API. After the integration architect evaluates the requirements and volume, they determine that the Fire and Forget integration pattern will be most appropriate for sending data from Salesforce to the external application and getting response back in a strongly-typed format.
Which integration capabilities should be used to integrate the two systems?

• A. Outbound Messaging for Salesforce to Legacy System direction and SOAP API using Enterprise WSDL for the communication back from legacy system to Salesforce
• B. Outbound Messaging for Salesforce to Legacy System direction and SOAP API using Partner Web Services Description Language (WSDL) for the communication back from legacy system to Salesforce
• C. Platform Events for Salesforce to Legacy System direction and SOAP API using Enterprise WSDL for the communication back from legacy system to Salesforce

A company that is a leading provider of courses and training delivers courses using third-party trainers. The trainer for the company has to be verified by 10 different training accreditation verification agencies before providing training for the company. Each training accreditation agency has its own response time, which means it could take days to confirm a trainer. The company decided to automate the trainer accreditation verification process by integrating it with the agency's web service1s. What is the recommended approach to automa2te this process?3456

• A. Make an Apex callout using @future annotation to make the callout to all different agencies.
• B. Use Salesforce External Service to make the callout; Salesforce External Service should check the verification agencies until the result is verified. Then, update the trainer status to "verified".
• C. Use middleware to handl7e the callout to the 10 different verific8ation services; the middleware will handle the business logic of con9solidating the verification resu10lt from the 10 services. Then, make a call-in to Salesforce and update the verification status to "verified".
