Salesforce ARC-101 Exam - Topic 8 Question 26 Discussion

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?
B) Let the Lightning Data Service with an wire adapter display new values when the custom object records change.
A) Use the Continuation class to call the Enterprise APIs and then process the response in a callback method.
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.

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?

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.

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.

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.
