Virtual Computing Chapter 1
What component of virtualization controls all physical memory, and thus has the ability to make any unused memory pages in each guest available for other virtual machines or the host computer?
The hypervisor
What statement regarding virtual disk types is accurate?
A dynamic disk does not immediately allocate the configured size of the disk.
Cloud services are highly reliant upon the use of virtualization technology.
True
What is the most commonly used form of a Storage Area Network?
An iSCSI network
A virtual machine can't share the use of a network adapter with the host
False
In virtualized computing, a single computer is capable of supporting a single operating system.
False
You are employed by a cloud service provider that offers virtual machine services along with virtual switches, storage, firewalls, and other virtual devices. What type of cloud environment does your employer sell?
Infrastructure as a Service
What is the purpose of a shadow page table when a hypervisor is used?
It tracks the memory pages allocated by each guest VM.
The VDI disk file format is native to what virtualization platform?
Oracle VirtualBox
What type of cloud computing service provides hardware infrastructure along with necessary operating system software for running client applications?
Platform as a Service
What virtualization technology makes it possible to avoid overhead associated with software-managed shadow page tables
Second Level Address Translation (SLAT)
What hypervisor uses a special guest called Domain 0 that loads along with the hypervisor and is used to directly access the hardware?
Xen
You have been tasked with creating a virtual machine that will require access to the Internet, but should be prevented from sending and receiving packets directly from the physical network. What network mode should be used?
shared (NAT) mode
What feature, supported by VMWare, allows the live migration of a running VM from one host to another?
vMotion
What statement regarding the use of Hyper-V is accurate?
Hyper-V requires a 64-bit processor with hardware virtualization support.
An ISO image file uses what format to store a disc's contents in a single file on a computer?
ISO 9660
When a Xen based guest VM makes a request for a hardware resource, such as reading from a disk, where is the request sent to?
It is sent to the Domain 0 guest.
What is NOT a product designed specifically for the virtualization of applications within a VDI environment?
VMware Fusion
Your work environment consists of a large number of Mac OS X based devices. The developers in your network have requested virtualization software be installed for their use. What product should you use?
VMware Fusion
You have been tasked with creating a virtual machine that will be providing hosted services on the physical network, and possibly the Internet. What network mode should be used?
bridged mode
