Wait, does it really replicate 3 copies? That seems excessive.

I’m a bit confused about the multiple cache layers mentioned in option C. Did we cover if it includes RAM, SSD, and HDD?
CH

Hey, I heard Alibaba's caching solution is so fast, it can pre-fetch your exam answers before you even finish reading the question. Talk about a 'smart' cache!
LE

Alright, let's see... A, B, C, D, and E. Gotta love that Alibaba engineering, always pushing the boundaries of what's possible with containers and Kubernetes. Although, I have to say, the thought of a cache that can outrun my coffee break is a little intimidating.
AU
Audria

E is definitely right, horizontal scaling is a must-have for any distributed caching solution. The other options sound legit too, though I'm not too sure about F. Replicating 3 copies of local data? Isn't that a bit overkill?
WI
Willodean

Yeah, replicating 3 copies of data does seem excessive. It might be unnecessary redundancy.
AR
