Virtualization Flashcards
Which type of computing scenario most closely describes virtualization?
A single computer in a dual-boot configuration
A single computer with a single operating system installed
A single physical computer hosting multiple logical computers
A single physical computer hosting multiple logical computers
Which computing scenario would NOT be an example of effectively using virtual machines?
Testing new software on a specific operating system
Evaluating a new version of an operating system
Supplying a user with a laptop to increase their mobility
Supplying a user with a laptop to increase their mobility
Which virtual machine resource setting often cannot be changed while the virtual machine is running?
Floppy disk drives
Memory
IDE hard drives
Memory
If you have a virtual machine running a 32-bit version of an operating system and it currently has 4 GB of RAM configured, what level of performance boost should you expect if you allocate an additional 4 GB?
Significant
None
Minimal
None
What functionality is provided by emulators in virtualization?
They allow the virtual machine to be moved to a different physical machine?
They intercept hardware requests from the physical machine and pass them to the virtual machine
They intercept hardware requests from the virtual machine and pass them to the physical machine
They intercept hardware requests from the virtual machine and pass them to the physical machine
Why should the security of a physical host machine be given additional consideration?
Because the corruption of any virtual machine means corruption of the host
Because the corruption of the host can result in corruption of all virtual machines on that host
Because the corruption of one virtual machine means corruption of all virtual machines on that host
Because the corruption of the host can result in corruption of all virtual machines on that host
Which type of computing configuration can result in a much higher demand on your local area network when using virtualization?
Desktop as a Service (Daas)
Virtual Private Network (VPN)
Virtual Desktop Infrastructure (VDI)
Virtual Desktop Infrastructure (VDI)
Which feature of hypervisors distinguishes type 1 from type 2?
Type 2 supports newer features that do not require as many emulators
Type 2 supports configuring settings while the virtual machine is running
Type 2 has a local operating system installed on the host system
Type 2 has a local operating system installed on the host system
