Salesforce ARC-101 Exam - Topic 8 Question 26 Discussion

Actual exam question for Salesforce's ARC-101 exam
Question #: 26
Topic #: 8
[All ARC-101 Questions]

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?

I recall something about Platform Events, but I'm not confident if that approach would solve the usability concern with incomplete data in this scenario.

Calling the Enterprise APIs directly from the LWC sounds familiar, but I worry about performance issues if there are too many transactions to process at once.

I think using Lightning Data Service could be a good option, but I’m not entirely clear on how it handles data synchronization with external APIs.

I remember discussing the Continuation class in class, but I'm not sure if it's the best fit here since it might not handle real-time updates effectively.

Okay, let me see here. The NIST model is all about cloud computing, so it's probably not going to require using multiple providers. I'm leaning towards option B, but I'll double-check my notes just to be sure.

Hey, at least the question didn't ask us to use a Batch Apex job to fetch the transactions. That would have been a real head-scratcher!

I'm not sure about option B. Relying on the Lightning Data Service might not be sufficient if the custom object is not updated frequently enough. We need a more proactive approach to fetch the data.
