Chat with AIExam 11: Windows Server 2008 Virtualization
Discuss the disadvantages of virtualization,and how those might be addressed.
(35) 
VerifiedOne disadvantage is that the server hardware can be a single point of failure.Plan to build in hardware fault tolerance and disaster recovery to reduce the impact of hardware failure.For example,consider purchasing server hardware that contains redundant power supplies,CPUs,memory,network interfaces,and RAID level 1 or level 5 disk storage fault tolerance.Another option is to have a backup server computer on hand in case the main one fails.As a disaster recovery step,the backup computer might already be set up with virtual machines to match those on the primary server; you can regularly back up data from the virtual machines on the primary server to those on the backup server.If the primary server goes down,the backup server can take over.For better disaster recovery,place the backup server computer in a different location from the primary server.
Another disadvantage of virtualization is that backing up all of the virtual machines on a single computer can be a much slower process than backing up a single server with a single operating system and no virtual machines.Backing up virtual machines can stress network,CPU,and memory resources on a single computer.You can reduce some of the burden by employing incremental backups.Another option is to purchase software designed to expedite backups on virtual machines.
____ allows the running of multiple workstation operating systems,such as Windows XP,Windows 7,and Linux,on one computer.

A(n)____ binds the network to a NIC in the virtual server,which in effect makes the NIC act like a virtual switch.
(34) VerifiedC
Explain the advantages of virtualization with respect to giving you freedom from hardware compatibility issues.
(45) For each virtual machine in Hyper-V,you can configure one of three virtual networking options using Hyper-V Manager's ____.
(33) Microsoft Hyper-V is an example of server virtualization software.
(36) In the Connection Window,the ____ menu includes options such as press the equivalent of CTRL+ALT+DEL and turn off the virtual machine.
(41) The key combination CTRL+ALT+LEFT ARROW is called the "____."
(36) When you take a snapshot,it creates only a very short pause in the virtual machine's operation.
(34) ____________________ virtualization allows you to divide a single network into multiple channels or bandwidths so that the network appears as multiple networks.
(27) The ____________________ partition is the disk partition that houses the Hyper-V software and the parent operating system.
(36) A(n)____________________ virtual network does not use the NIC in the virtual server and is generally used to prevent network traffic from reaching virtual machines.
(35) ____________________ virtualization allows you to set up multiple networked disk storage units to appear as one unit.
(34) Virtual machines are faster to deploy but they are generally slower to port to another computer.
