Changing the z-value field won't help much in this case.

I agree, the power setting can really influence the results.

Wait, is the output cell size really that impactful?

I think adjusting the power parameter is key too!

Definitely consider changing the search radius.

I feel like the z-value field is less relevant in this case. It’s more about how the IDW weights the points, so power and search radius seem more likely to be the right choices.

I practiced a similar question where changing the output cell size made a difference, but I don't think that's the main issue here.

I'm not entirely sure, but I think the search radius might also be important. If it's too large, it could be pulling in those high edge values from too far away.

I remember that the power parameter can really influence how much the nearby points affect the interpolation. Maybe adjusting that could help with the edge values?

Okay, I've got it! The key here is that the question is asking about costs that are "classified as" something. So the answer is likely one of the options provided, rather than an open-ended definition. I'm going to go with B - Non-value Add.

Hmm, this looks like a pretty complex test plan to analyze. I'll need to carefully review the content sample to see how well the sections are aligned.

I think the answer is B, Availability management. They would have the best understanding of potential service disruptions that could impact the continuity plan.

Band select sounds familiar, I remember reading that it helps roaming clients connect to the right band. But was it really the main setting for high-density networks?
