A) Ensure that the object you don't want to be cached anymore is not shared publicly.
B) Create a new storage bucket, and move the object you don't want to be checked anymore inside it. Then edit the bucket setting and enable the private attribute.
C) Add an appropriate lifecycle rule on the storage bucket containing the two objects.
D) Add a Cache-Control entry with value private to the metadata of the object you don't want to be cached anymore. Invalidate all the previously cached copies.

Yeah, but isn't it better to just keep things public for easier access?

I vaguely recall that lifecycle rules are more about managing object retention rather than caching. So I don't think option C is relevant here.

I practiced a similar question where we had to manage caching settings. I think adding a Cache-Control entry is a common solution, so D sounds plausible.

I'm not entirely sure, but I feel like creating a new bucket just to change the privacy settings seems a bit excessive. Option B might not be the best.

I think I remember something about Cache-Control headers being important for caching behavior. Maybe option D is the right choice?

I'm pretty sure the Coastal Zone Management Act was passed in the 1970s, so I'll go with option C.

This question seems straightforward. I think the answer is B - cost tolerance can be fixed or flexed in an agile context.

I'm a little confused by the wording here. What exactly do they mean by "qualitative and quantitative insights about the level of risk"? I'll need to re-read the question a few times to make sure I understand what they're asking.

Option D, no question. Anything else is just going to create more work than necessary. Plus, who wants to deal with a whole new bucket just for one object?

Ah, the age-old question of how to override a CDN cache. I've been there before. Option D is the way to go, no doubt about it.
