Which of the following answers refers to a cloud-based VDI service?
IaaS
PaaS
DaaS
SaaS
Daas
Desktop as a Service (DaaS) is a cloud computing offering where a service provider delivers virtual desktops to end users over the Internet, licensed with a per-user subscription.
Which of the terms listed below refers to a solution that allows multiple operating systems to work simultaneously on the same hardware?
Virtualization
Clustering
Hyperthreading
Multitasking
Virtualization
In virtualization technology, a software program that manages multiple operating systems (or multiple instances of the same operating system) on a single computer system is known as:
Hypervisor
Virtual switch
Host machine
Virtual machine
hypervisor
A hypervisor, also known as a virtual machine monitor or VMM, is software that creates and runs virtual machines (VMs). A hypervisor allows one host computer to support multiple guest VMs by virtually sharing its resources, such as memory and processing.
Which of the following statements describe disadvantages of virtualization? (Select 2 answers)
Multiple virtual machines run on a single host share hardware resources which has a degrading effect on performance
In a virtualized environment, deployment of different types of OSs or multiple copies of the same OS or application becomes more difficult due to hardware configuration issues
On a larger scale, virtualization has a negative effect on operational costs due to increased power supply requirements
Hardware used for hosting virtual machines becomes a single point of failure
Multiple virtual machines run on a single host share hardware resources which has a degrading effect on performance
Hardware used for hosting virtual machines becomes a single point of failure
