Calling an Apex method for this? That feels like overkill.

I’m surprised this isn’t a more common approach in LWC!

Wait, why not just update a property on the parent? Seems simpler.

I think creating a custom event is the way to go.

I keep getting confused between firing notifications and custom events. I guess both are ways to communicate, but I think custom events are more specific for this scenario.

I practiced a similar question where we had to use events to handle navigation. I think creating a custom event is the way to go for this one.

I'm not entirely sure, but I feel like updating a property on the parent could work too. It seems simpler, but does it really notify the parent properly?

I remember we talked about using custom events for communication between components. I think that might be the right approach here.

I'm a bit confused by the question. Can we share storage between vSAN clusters in this way? I'll need to review the vSAN documentation to make sure I understand the capabilities.

Hmm, this seems straightforward. I think the new state will be "Duplicated" since that's the option that makes the most sense when clicking the "Mark Duplicate" button.

A mobile-optimized website is definitely the way to go here. That's got to be the key concern they're getting at.
