Really? I always thought HFiles were more flexible than that!

Nope, one HFile only holds data for one column family.

Wait, I thought HFiles could have multiple column families?

Totally agree, HFiles are tied to specific Regions.

A HFile actually belongs to one Region, that's true.

I vaguely recall that HFiles can store multiple rows, so option D might not be the right answer either.

I feel like option C could be misleading; HFiles do contain multiple columns, but I'm not sure if that's the main issue here.

I remember practicing a question about HFiles and column families, and I think option B is definitely incorrect because HFiles should only belong to one column family.

I think HFiles are tied to regions, so option A seems correct, but I'm not entirely sure.

Base64 encoding uses a specific set of characters, so that's my best guess based on the HEX string.

I'm not too familiar with the Horizon View architecture, so I'll need to think this through carefully. I don't want to rush and accidentally select the wrong options.

I've got a good strategy for this. I'll read through the options, eliminate the ones that don't seem relevant, and then select the three that can be customized.

I'm pretty confident on this one. The getCurrentPosition function takes a success callback and a failure callback as its two arguments. The success callback is where you handle the location data, and the failure callback is where you handle any errors that occur. I feel good about selecting those two options.

This looks like a classic workflow automation problem. I think the Dataproc Workflow Template is the way to go - it should let me easily define the sequence and concurrency of the Spark jobs.

Hmm, I'm a bit unsure about this one. I think it might be D, Projection/surface pattern, but I'm not 100% confident.
