Which of the following is not part of a healthy virtualization implementation?

• An efficient DR plan
• Low hardware utilization
• High availability
• Backups 

EXPLANATION

The biggest issue of on-premises data centers, which have dedicated servers for each workflow, is very low hardware utilization. Companies simply can’t afford to run out of server capacity because their line-of-business (LOB) applications will work slowly or even stop, which is going to impact their revenues, so they oversize their hardware. Resource utilization of such servers is usually below 20% — they are not used at their full potential.
A healthy hypervisor implementation should have high availability (can be done by host clustering), backups (can be done by a variety of backup/replication software) and an efficient DR plan.
