Wait, really? I thought it grouped them by likes.

Nah, it doesn't set the _id to null like that.

It counts posts with likes between 100 and 200.

I’m leaning towards option C, as it seems the most straightforward based on what we studied about aggregate queries.

I feel like option D sounds familiar, but it seems a bit complicated for what the question is asking.

I remember a practice question that involved grouping data by likes, but I can't recall if that's what this one does.

I think this query might be calculating the number of posts with likes between 100 and 200, but I'm not entirely sure.

Okay, let me think this through. A SnapMirror license is definitely required, but I'm not sure if a separate SnapMirror Synchronous license is needed on both clusters or just one. I'll go with A and D to be safe.

Okay, let me see... The PRINCE2 method has four integrated elements, and the question is asking about the missing one. I'm leaning towards "processes" as the best answer, but I'll double-check the other options just to be sure.
