guarantee of power
support of live migration*
supply of consistent air flow
improvement of business practices
13. What is a difference between the functions of Cloud computing and virtualization?
Cloud computing utilizes data center technology whereas virtualization is not used in data centers.
Cloud computing requires hypervisor technology whereas virtualization is a fault tolerance technology.
Cloud computing separates the application from the hardware whereas virtualization separates the OS from the underlying hardware.*

has direct access to server hardware resources
does not require management console software*
17. Which is a characteristic of a Type 1 hypervisor?
does not require management console software
installed directly on a server*
installed on an existing operating system
best suited for consumers and not for an enterprise environment
18. How is the control plane modified to operate with network virtualization?
Control plane redundancy is added to each network device.
The control plane function is consolidated into a centralized controller.*
A hypervisor is installed in each device to allow multiple instances of the control plane.
