Double-digit revenue growth is great, but I'm not sure that's the full picture of what defines the "sweet spot" for Industry 4.0. I'll need to consider the technical aspects as well.

I don't know, Memory Management does seem important, but I'm leaning more towards I/O Management based on those disk contention issues we discussed in class.

I think the key here is that the tester needs to be involved in security testing, but they don't necessarily have to do it all themselves. Collaborating with security experts is probably the best approach.
