Removing a measure seems risky; we need all the data we can get.

I practiced a similar question where increasing clusters helped, so I’m leaning towards option D, but I need to think it through more.

Removing one of the measures seems risky; I feel like we might lose important information that could help with classification.

I think adding more measures could provide better separation between the clusters, but I’m not confident about which measures would be effective.

I remember reading that increasing the number of clusters can sometimes help reduce overlap, but I'm not entirely sure if that's the best approach here.

I think the answer is B. The whitelist will allow mysoftware.exe to run, but it will still be uploaded to WildFire for analysis.

I recall that breaches of duty can lead to liability for the director, which makes me lean toward option 3 being correct.

This looks like a classic out-of-memory issue during training. I think reducing the batch size is the way to go here.

I think RHEL is based on Fedora, but I'm not entirely sure. I remember it being something like a core or upstream version.
