Replicating content in a Cloud Storage bucket seems like a good idea, but I can't recall if it's the best option for improving cache hits.

I feel like the ''Cache-Region'' header might be important, especially for users in different locations. That sounds familiar.

I think shortening the expiration time could actually hurt the cache hit ratio, but I need to double-check that.

I remember discussing cache keys in class, but I'm not sure if omitting the protocol really helps with the hit ratio.

Hmm, I'm a bit unsure about this one. The exhibit shows a lot of information, and I want to make sure I understand which IP address is relevant for joining the node to the cluster.
