I disagree with D, I thought only one function could be used.

C is correct, those functions work for integers.

Ardella 12 months ago

Wait, can we really apply multiple functions? Sounds odd.

Noel 12 months ago

I agree, B is definitely false.

Cammy 12 months ago

Option A is true, it includes all attributes.

Option D seems right too, but I can't recall if there are any limitations on how many functions we can apply in one Aggregate.

I remember practicing a question similar to this, and I think option C is definitely true because we can use those functions on integer types.

I'm not entirely sure about option B; I feel like it might be true since greyed-out columns often indicate they won't be included.

I think option A sounds correct because we usually get all the attributes plus the aggregation columns in an Aggregate.

This is a good one. I remember learning about the NumberFormat class and how to use it for currency formatting. I think option D is the way to go here.

I'm not totally sure, but option C seems off, since imaging doesn't really keep non-trained people out of the drive, right?

Okay, let me review my notes on the File API. I think Blob and FileList are the two interfaces they're asking about in this question.

This seems like a straightforward question about enabling logging for data access. I think the answer is D - Enable Data Access audit logs for the Cloud Storage API.

Hmm, I'm a bit unsure about this one. I'll need to review the details on active vs. eligible roles in Privileged Identity Management to make sure I select the right option.
