Virtual Hands On chapter 1
Oracle VirtualBox
The VDI disk file format is native to what virtualization platform?
True
The hypervisor intercepts and processes requests coming from the guest operating systems and then returns the results back to the virtual machine.
Infrastructure as a Service
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?
The hypervisor
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?
Not VDI
What format enables a virtual machine to be moved between virtualization platforms, and is often used for deploying virtual appliances?
VMware Fusion
What is NOT a product designed specifically for the virtualization of applications within a VDI environment?
OVF is the standard that was created by vendors . By using the OVF format and different types of software you can take that format and run your VM from one host to the other.
What is the Open Virtualization Format, and how does it facilitate the migration of virtual machines between hypervisors?
Templates are similar to clones. The difference is that a clone runs VM and a template isn't. (needs more)
What is the difference between a template and a clone?
An iSCSI network
What is the most commonly used form of a Storage Area Network?
OpenStack
What open standard was developed as a result of collaboration between NASA and Rackspace?
A dynamic disk does not immediately allocate the configured size of the disk.
What statement regarding virtual disk types is accurate?
Platform as a Service
What type of cloud computing service provides hardware infrastructure along with necessary operating system software for running client applications?
interacts with hardware through the hypervisor
Which of the following does an operating system installed in a guest virtual machine do?
Not shared mode
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?
True
Cloud services are highly reliant upon the use of virtualization technology.
IAAS is the most basic service and allows a company to pay for the services as they need them. Paas is a hardware infrastructure with an operating system. A small company would be able to rent a cloud environment with what they needed instead of purchasing high cost software licenses. And SaaS is known as the most common. With this you can run your applications and software from the cloud and don't have to worry about installing it on every device.
How do the three types of cloud computing differ from each other?
Not just with distributing the software but with developing the software. Multiple OS can be tested with the software without the cost of having 3 separate PC running 3 different OSs.
How might a software developer benefit from the use of virtualization?
