I thought STRIP_NULL_VALUES was for something else.

I’m confused; I thought SKIP_BYTE_ORDER_MARK was related to file formats, not verification. I need to double-check my notes!

I’m leaning towards VALIDATION_MODE as well. It sounds familiar from a similar practice question we did last week.

I remember practicing a question about COPY commands, and I feel like STRIP_NULL_VALUES was mentioned, but it doesn't seem right for verification.

I think the parameter for verifying data files might be VALIDATION_MODE, but I'm not entirely sure.

I've got a good feeling about VALIDATION_MODE. That seems like the most relevant option for verifying data files.

I'm a bit unsure about this one. I'll need to double-check the COPY command documentation to make sure I understand the different parameters.

Ah, I remember learning about the VALIDATION_MODE parameter in our SQL lessons. That sounds like it could be the right answer.

Okay, I think the key here is to find the parameter that verifies the data files instead of loading them. Let me review the options.

Wait, so we can't go back and review the previous questions? That's going to make this a bit more challenging. I'll need to make sure I get it right the first time.

Ah, this one's tricky. I think I remember seeing something about creating IBM Object Storage in the web console, but I can't recall if that's a valid selection from the home page. I'll have to think this through.

Wait, do we need to do all four steps or just a subset? I want to make sure I select the right answer choice. Let me re-read the question carefully.
