Which type of cache invalidation does the Cache scope support without having to write any additional code?

Show Suggested Answer Hide Answer
Suggested Answer: C

The Cache scope supports time to live (TTL) as a cache invalidation strategy without having to write any additional code. TTL specifies how long the cached response is valid before it expires and needs to be refreshed. The Cache scope also supports custom invalidation strategies using MEL or DataWeave expressions.

I vaguely recall that notification-based invalidation is the easiest to implement without extra code, so I’m leaning towards D as well.

I practiced a similar question last week, and I think it was about write-through invalidation. But I'm confused if that's the right context here.

I'm not entirely sure, but I feel like Time to live (C) was discussed in relation to automatic cache management.

I think the answer might be D, Notification-based invalidation. I remember it being mentioned in a lecture about cache scopes.

I'm leaning towards D. Notification-based invalidation. That seems like it would fit with the Cache scope's built-in functionality, but I'm not 100% sure. I'll have to review my notes to be certain.

Okay, let me think this through step-by-step. The question is asking about the type of cache invalidation the Cache scope supports without additional code. That means it's likely one of the default options, not something custom-built. Based on the choices, I'd say C. Time to live seems like the most likely answer.

Hmm, I'm a bit unsure about this one. I know the Cache scope has some built-in invalidation options, but I can't quite remember which ones off the top of my head. I'll have to think this through carefully.

I'm pretty sure the answer is C. Time to live seems like the most straightforward cache invalidation approach that the Cache scope would support without additional code.

White-behind invalidation? I think that's what happens when you accidentally spill milk on your white shirt. Not exactly a cache management strategy.

Notification-based invalidation? That's like getting a warning when your food in the fridge is about to expire. Useful, but not exactly what we're looking for here.

Write-through invalidation? That's like trying to clean your car by driving it through a car wash while it's still moving. Not the most efficient approach.
