Unit 2 Revision : Virtualization

................................ is way to run multiple operating systems and user applications on the same hardware

• Virtualization

• Storage

• Data Warehousing

• Data Mining

Which of this is best defines Virtualization

• It is the process of running a virtual instance of a computer system in a layer abstracted from the actual hardware.

• allows one computer to do the job of multiple computers, by sharing the resources of a single hardware across multiple environments

• Provides

  Abstraction – to simplify the use of the underlying resource (e.g., by removing details of the resource’s structure)

  •Replication – to create multiple instances of the resource (e.g., to simplify management or allocation)

  Isolation – to separate the uses which clients make of the underlying resources (e.g., to improve security)

• All of the Above

What is API, ABI and ISA

• Application Programming Interface, Application Binary Interface and Instruction Set Architecture

• American Programming Interface, American Binary Interface and International Set Architecture

• Application Programming Interface, Application Business Interface and Instruction Set Algorithm

• Application Prediction Internals, Application Business Interface and Instruction Set Algorithm

One of these is a software for Type 2 Hypervisor.

• VMware ESX

• Microsoft Hyper-V

• Xen

• VMware Workstation

Which is more secure? Microkernal or Monolithic hypervisor

• Microkernal

• Monolithic

• Both are not secure

• Both are highly secure

Ability to display a graphical desktop from one computer system on another computer system or smart display device is known as

• Machine Virtualization

• Network Virtualization

• Desktop Virtualization

• Storage Virtualization

Type 1 Hypervisor.......................

Type 2 Hypervisor .......................

• also called bare metal or native

  also known as hosted hypervisors

• also known as hosted hypervisors

  also called bare metal or native

• also called as full virtualization

  also called as new virualization

• None of the above

..........................It is a multi-national cloud system that integrates private, community, and public clouds into scalable computing platforms.

• Federated Cloud

• Service Oriented Architecture

• Virtualization

• IoT

Public cloud + private Cloud = ??

• Federated cloud

• Virtual Cloud

• Hybrid Cloud

• Google Cloud

....................................refers to the process of moving a running virtual machine or application between different physical machines without disconnecting the client or application. Memory, storage, and network connectivity of the virtual machine are transferred from the original guest machine to the destination.

• Hybrid Cloud

• Federated Cloud

• Live migration

• Distributed Virtual Machine
