A company in a heavily regulated industry requires data in legacy systems to be displayed in Salesforce user interfaces (UIs). They are proficient in their cloud-based ETL (extract, transform, load) tools. They expose APIs built on their on-premise middleware to cloud and on-premise applications.
Which two findings about their current state will allow copies of legacy data in Salesforce?
Choose 2 answers

• A. Only on-premise systems are allowed access to legacy systems.
• B. On-premise middleware provides APIs to legacy systems data.
• C. Legacy systems can use queues for on-premise integration.
• D. Cloud-based ETL can access Salesforce and supports queues.

Customer is evaluating Platform Events solution and would like help in comparing/contrasting it with Outbound Message for a real-time / near-real time needs. They expect 3,000 consumers of messages from Salesforce.
Which three considerations should be evaluated and highlighted when deciding between the solutions?
Choose 3 answers

• A. Number of concurrent subscribers to Platform Events is capped at 2,000. An Outbound Message configuration can pass only 100 notifications in a single messages to a SOAP end point.
• B. Message sequence is possible in Outbound Message but not guaranteed with Platform Events. Both offer very high reliability. Fault handling and recovery are fully handled by Salesforce.
• C. Both Platform Events and Outbound Message are highly scalable. However, unlike Outbound Message, only Platform Events have Event Delivery and Event Publishing limits to be considered.
• D. Both Platform Events and Outbound Message offer declarative means for asynchronous near-real time needs. They aren't best suited for real- time integrations.
• E. In both Platform Events and Outbound Messages, the event messages are retried by and delivered in sequence, and only once. Salesforce ensures there is no duplicate message delivery.

A company's cloud-based single page application consolidates data local to the application with data from on premise and 3rd party systems. The diagram below typifies the application's combined use of synchronous and asynchronous calls.

The company wants to use the average response time of its application's user interface as a basis for certain alerts. For this purpose, the following occurs:
1. Log every call's start and finish date and time to a central analytics data store.
2. Compute response time uniformly as the difference between the start and finish date and time - A to H in the diagram.
Which computation represents the end-to-end response time from the user's perspective?

• A. Sum of A and H
• B. Sum of A, G, and H
• C. Sum of A to F
• D. Sum of A to H

Northern Trail Outfitters (NTO) use Salesforce to track leads, opportunities, and to capture order details. However, Salesforce isn't the system that holds or processes orders. After the order details are captured in Salesforce, an order must be created in the remote system, which manages the orders lifecylce. The Integration Architect for the project is recommending a remote system that will subscribe to the platform event defined in Salesforce.
Which integration pattern should be used for this business use case?

• A. Request and Reply
• B. Fire and Forget
• C. Batch Data Synchronization
• D. Remote Call In

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?

• A. Call the Enterprise APIs directly from the LWC's JavaScript code and redisplay the LWC on receipt of the API response.
• B. Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.
• C. Publish a Platform Event, have the middleware subscribe and update the custom object on receipt of Platform Event.
• D. Let the Lightning Data Service with an @wire adapter display new values when the custom object records change.
