Salesforce ARC-101 Exam - Topic 10 Question 63 Discussion

Actual exam question for Salesforce's ARC-101 exam

Question #: 63
Topic #: 10

Northern Trail Outfitters (NTO) leverages Sales Cloud for tracking and managing leads, accounts, contacts, and opportunities- Orders and order fulfillment is taken care of by an Order Management System (OMS) in the back-office. When an opportunity has changed it's status to "Closed/Won" and there are products attached, the details should be passed to the OMS for fulfillment operations.

The callout from Salesforce to the OMS should be synchronous.

What should an Integration Architect do to satisfy these requirements?

AWrite a trigger that invokes an Apex proxy class to make a REST callout to the Order Management System.

BUse Process Builder to call an Apex proxy class to make a REST callout to the Order Management System.

CDevelop a batch Apex job that aggregates Closed Opportunities and makes a REST callout to the Order Management System hourly.

DBuild a Lightning Component that makes a synchronous Apex REST callout to the Order Management System when a button is clicked.

I think the trigger approach is more reliable for this scenario.

Wait, can a Lightning Component really handle synchronous calls?

Batch jobs (Option C) won't work for immediate fulfillment.

I disagree, Process Builder (Option B) is easier to manage!

Option A seems like the best choice for real-time updates.

I’m a bit confused about option D; it seems like a Lightning Component might not be the best approach for this scenario since it requires user interaction.

I practiced a similar question about integrating with external systems, and I think batch Apex like in option C wouldn't meet the synchronous requirement.

I'm not entirely sure, but I feel like using Process Builder in option B could work too, especially since it can trigger actions based on record changes.

I remember we discussed the importance of synchronous callouts for real-time processing, so I think option A might be the right choice.

This seems pretty straightforward to me. I'd go with the trigger solution - it's the most direct way to meet the synchronous requirement.

I'm a bit confused by the different options here. I'll need to make sure I understand the differences between the trigger, Process Builder, and batch job approaches before deciding.

Okay, I've got a plan. I think I'll go with the trigger option since that will ensure the callout happens right when the opportunity is closed. The synchronous part should be doable with an Apex proxy class.

Hmm, not sure about this one. The synchronous callout is a bit tricky - I'll need to review the options and make sure I understand the implications of each approach.

This looks like a straightforward integration problem, but I'll need to think through the synchronous requirement carefully.

Haha, can you imagine the order management team's faces if the Integration Architect decided to go with a batch job for this? 'Sorry, guys, you'll just have to wait an hour for your orders to process!'

Ah, the old synchronous Apex REST callout. Option D might work, but I'm not sure I like the idea of the user having to click a button. Feels a bit clunky.

But wouldn't building a Lightning Component for synchronous callouts be more efficient?

Batch Apex? Really? That's overkill for this use case. I'd avoid Option C, it's just introducing unnecessary complexity.

I'm not a big fan of triggers, they can get messy. I'd go with Option B and use Process Builder instead. Seems cleaner and more maintainable.

Option A looks like the way to go. A trigger will ensure the callout happens right when the opportunity is closed, which is exactly what the requirement specifies.
