Yeah, D makes sense. Oversampling shouldn't mess with those metrics.

Just to clarify, PV+ and PV- can be influenced by the sample size, right?

Wait, are you sure about that? I thought oversampling changes everything.

If I recall correctly, sensitivity and specificity are calculated from the confusion matrix itself, so they remain unaffected by the sample size changes.

I'm a bit unsure, but I feel like sensitivity might be affected by oversampling since it deals with true positives.

I think I saw a practice question about this, and it mentioned that oversampling mainly affects positive predictive values.

I remember that sensitivity and specificity are based on the actual outcomes, so they shouldn't change with oversampling, right?

This seems pretty straightforward. I'd go with option A - inserting a widget to display a CMS block with the message.

My instinct says D could work too, especially if (II) has a steady return, but I might be second-guessing myself here.

This is a good question that tests our understanding of hardware security modules and their use cases. I think the embedded cryptoprocessor and hardware-backed public key storage are the two key features that would enable secure remote access, so those are the ones I'll select.

This seems like a straightforward question about NAS service capacity management. I'll focus on the key sub-processes mentioned in the options.

Okay, I've got this. The correct answers are A and E - a developer would create a custom form stencil to make custom form controls available to the Process Designer, and to limit the form controls that are available to the Process Designer. The other options are not directly related to the purpose of a custom form stencil.
