Salesforce Exam ARC-101 Topic 8 Question 26 Discussion

Actual exam question for Salesforce's ARC-101 exam

Question #: 26
Topic #: 8

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?

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

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

CCall the Enterprise APIs directly from the LWC's JavaScript code and redisplay the LWC on receipt of the API response.

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

C) looks like the most straightforward approach to me. Calling the APIs directly from the LWC component and updating the UI accordingly seems like the best way to ensure we display all the required transactions.

I see both points, but I think option B could also work well. Letting the Lightning Data Service with a wire adapter display new values when custom object records change can provide a seamless user experience.

I disagree, I believe option D is the way to go. Publishing a Platform Event and having the middleware update the custom object will ensure real-time updates and accurate data on the LWC.

I think option A is the best choice because using the Continuation class will allow us to call the Enterprise APIs asynchronously and process the response efficiently.
