I thought you could change specs on the fly, though?

No instance type included is a big one too.

This question seems straightforward, I think the answer is B. Testers are more motivated when their contributions are recognized and they are given increased responsibilities.

I feel like break-even means we cover our fixed costs with sales, so maybe it's C? That seems to fit what we practiced in class.

Whoa, this is a serious security event. I think the best approach is to immediately contain the rogue AP to prevent any potential damage, and then worry about the other details later.

I'm a bit confused on this one. I'm not sure if the high site would have a higher or lower transmit frequency. I'll need to review the key principles behind microwave link design.
