Question 1

An enterprise architect has requested the Salesforce Integration architect to review the following (see diagram & 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 UI concurrently to check eligibility of a customer for a qualifying offer.

* There are multiple eligibility systems that provides 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 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 customer's API Gateway layer and the API Gateway imposes a constraint of timing out requests after 9 seconds.

Which three recommendations should be made?

Choose 3 answers

Options :

A : ESB (Mule) with cache/state management to return a requestID (or) response if available from external system.

B : Recommend synchronous Apex call-outs from Lightning UI to External Systems via Mule and implement polling on API gateway timeout.

C : Use Continuation callouts to make the eligibility check request from Salesforce from Lightning UI at page load.

D : When responses are received by Mule, create a Platform Event in Salesforce via Remote-Call-In and use the empAPI in the lightning UI to serve 3,000 concurrent users.

E : Implement a 'Check Update' button that passes a requestID received from ESB (user action needed).

Answer: A,C

Question 2

A company needs to integrate a legacy on premise application that can only support SOAP API. After the Integration Architect has evaluated the requirements and volume, they determined 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?

Options :

A : Outbound Message for Salesforce to Legacy System direction and SOAP API using Enterprise WSDL for the communication back from legacy system to salesforce.

B : Platform Events for Salesforce to Legacy System direction and SOAP API using Partner 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.

D : Outbound Message for Salesforce to Legacy System direction and SOAP API using Partner WSDL for the communication back from legacy system to salesforce.

Answer: A

Question 3

A business wants to integrate its eCommerce platform with Salesforce to better track and engage its customers. What is a key factor that should be included as an integration requirement for CRM success?

B : Sync only the customer data that has been updated in the last 30 days

C : Real-time syncing of customer and order data between both platforms

D : Import all historical order data into Salesforce

Answer: C

Question 4

Your company has two separate Salesforce Orgs: one for sales and another for customer service.

Which integration pattern would best meet this requirement?

A : Request-Reply

B : Remote Call-In

C : Remote Process Invocation – Fire and Forget

D : Remote Process Invocation – Request and Reply

Answer: D

Question 5

A conglomerate is designing a Lightning Web Component (LWC) to display transactions aggregated from different sources. Their current system landscape is as follows:

1. Transactions are created at any time through their various on-premise and cloud-based systems.

2. All necessary transactions are replicated to a custom Transaction object in Salesforce. It is updated periodically so it only has a subset of the necessary transactions between updates.

3. Middleware supports publish-subscribe interactions and provides RESTful Enterprise APIs that can retrieve transactions from on-premise and cloud-based systems.

The company wants to address a usability concern regarding incomplete data displayed on the LWC component. What should the Integration Architect specify so the LWC will be able to display all the required transactions?

Options :

A : Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.

B : Let the Lightning Data Service with an wire adapter display new values when the custom object records change.

C : Call the Enterprise APIs directly from the LWC-s JavaScript code and redisplay the LWC on receipt of the API response.

D : Publish a Platform Event, have the middleware subscribe and update the custom object on receipt of Platform Event.
