Show Suggested Answer Hide Answer
Suggested Answer: A, C

Comprehensive and Detailed Explanation From Exact Extract:

A (Correct):AVisualforce quick actioncan include Apex logic for a callout, and Visualforce is still valid in Lightning Experience.

C (Correct):ALightning Web Component (or Aura component)exposed as aquick actioncan perform callouts via Apex when the user clicks a button. This supports a more modern UI experience.

Incorrect options:

B:@future(callout=true) works but cannot be triggeredsynchronously by a button press. It's for background/automated processes.

D:Remote Actionis legacy functionality used with Visualforce/Aura and doesn't suit modern Lightning and button-driven synchronous actions.


This is part ofUser Interface (25%)andProcess Automation and Logic (30%), involvingintegration techniques and callouts.

I feel like we practiced a similar question where we had to choose between quick actions and triggers. I think option A could be a valid approach, but I’m leaning towards option C for the Lightning context.

I'm not entirely sure, but I think using an after update trigger could be risky because it might lead to governor limits being hit. Option B seems like it could work, but I’m not confident.

I remember we discussed the differences between Visualforce and Lightning components in class. I think option C might be the best choice since it aligns with Lightning Experience.
