HBase APIs? Not sure that’s the solution here.

I think doubling the nodes could help too.

I vaguely recall something about evenly spreading keys across the alphabet being a best practice. That might be the right approach here.

I practiced a similar question about optimizing Bigtable performance, and I think doubling the nodes could help, but it might not address the hot-spot problem directly.

I'm not entirely sure, but I feel like just deleting old records might not solve the underlying issue. It seems more like a temporary fix.

I remember we discussed hot-spotting in Cloud Bigtable during our study sessions. I think reviewing the RowKey strategy could help distribute the load better.

Hmm, I'm a bit unsure about this. I know the STEP model is about testing, but I can't quite remember the details. I'll have to think this through carefully.

Ah, I remember learning about this in class. The daemon that handles the interface between the Veritas commands and the kernel is vxconfigd. That's the right answer, B.

I think the answer is www.validator.w3.org, but I'm not completely sure. We covered a few validation tools in class.
