That said, most responsible boot camp vendors require attendees to have at least one year's experience with the tools and technologies being taught, so they can concentrate primarily on exam preparation. I would be very worried about entrusting my systems or networks to somebody whose only experience with tools and technologies came from a boot camp; but for those already in the know just trying to get certified, it's not such a big deal. According to boot camp operators I've interviewed, about 75-80% of all attendees there have their costs covered by employers or some other source of funding (scholarship, VA/GI Bill, etc.). That tells me that it's expedient for employers to send their people to boot camps, and probably explains why they remain so popular.
