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.
There are multiple eligibility systems that provide this service and are hosted externally.34 However, their current response times could take up to 90 seconds to process and return.
These eligibility systems can be acc8essed through APIs orchestrated via ESB (MuleSoft).
All requests from Salesforce must traverse the customer's API Gateway layer, which imposes a constraint of timing out requests after 9 seconds.

Which recommendation should the integration architect make?

• A. 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.
• B. Use Continuation callouts to make the eligibility check request from Salesforce Lightning UI at page load.
• C. Recommend synchronous Apex callouts from Lightning UI to External Systems via Mule and implement polling on an API Gateway timeout.

A customer is evaluating the Platform Events solution and would like help in comparing/contrasting it with Outbound Messaging for real-time/near-real time needs. They expect 3,000 customers to view messages in Salesforce. What should be evaluated and highlighted when deciding between the solutions?12

• A. Message sequence is possible in Outbound Messaging, but not guaranteed with Platform Events. Both offer very high reliability. Fault handling and recovery are fully handled by Salesforce.
• B. Both Platform Events and Outbound Messaging are highly scalable. However, unlike Outbound Messaging, only Platform Events have Event Delivery and Event Publishing limits to be considered.
• C. In both Platform Events and Outbound Messaging, the event messages are retried by and delivered in sequence, and 3only once. Sales4force ensures there is no duplicate message delivery.

A customer is migrating from an old legacy system to Salesforce and wants to integrate all existing systems currently working with the legacy application. Which constraint/pain-point should an integration architect consider when choosing the integration pattern/mechanism?

• A. Reporting and usability requirements
• B. Data volume and processing volume
• C. Multi-language and multi-currency requirement

Northern Trail Outfitters (NTO) uses Salesforce to track leads, opportunities, and order details that convert leads to customers. However, orders are managed by an external (remote) system. Sales reps want to view and update real-time order information in Salesforce. NTO wants the data to only persist in the external system. Which type of integration should an architect recommend to meet this business requirement?

• A. Process Orchestration
• B. Data Synchronization
• C. Data Virtualization

• B. In both Platform Events and Outbound Messaging, the event messages are retried by and delivered in sequence, and only once. Salesforce ensures there is no duplicate message delivery.
• C. Both Platform Events and Outbound Messaging offer declarative means for asynchronous near-real time needs. They aren't best suited for real-time integrations.
