DFD4043 QUIZ 3

Name a software tool that will be installed on the host system to provide a layer of abstraction. Once the tool is installed, OSes and applications interact with the virtualized resources abstracted by it and not with the physical resources of the actual host computer.

• hypervisor

• virtualization

• virtual machine

• pooling machine

Select the option that describe a benefit of virtualized servers.

• Shared hardware

• Individual hardware per virtual server

• Physical servers taking less room space than virtual servers

• Virtual servers taking less disk space than physical servers

Identify the INCORRECT software used in full virtualization.

• Xen

• VmWare

• KMV

• HyperV

Select the software that can be used for Full virtualization and also Para virtualization.

• KVM

• Xen

• HyperV

• VmWare

The characteristics as shown in Figure A1 is described about:

• Para virtualization

• Full virtualization

• Hardware virtualization

• Complete virtualization

“These hypervisors run on a conventional operating system (OS)”.

Match the hypervisor that suits the above statement.

• Type 1

• Type 2

• Network

• Server

Identify the INCORRECT statement regarding virtualization:

i. A client can request access to a virtual machine from any location

ii. A cloud has only one application instances and directs requests to an instance based on their searching

iii. Computers can be partitioned into a set of virtual machines with each machine being assigned a workload

iv. Server virtualization software runs between the operating system and the hardware

• i only

• ii only

• ii and iv

• i, ii, iii and iv

Relate the problem as mentioned in the situation as shown in Figure A2 with the CORRECT method given below.

• Migrate the in-house web application server to the cloud

• Create a new cloud server, install web services, and import web application data.

• This cannot be done because only generic applications are available through the cloud.

• Create a new cloud server, install web services, and install and configure web applications

Choose the difference between the operation of traditional dual boot (multiple operating system in a machine) with OS virtualization.

• Traditional dual boot allows users to use multiple operating system meanwhile OS virtualization only allows one operating system.

• Traditional dual boot allows users to use only one operating system meanwhile OS virtualization allows multiple operating system.

• Traditional dual boot allows users to use only one operating system at a time meanwhile OS virtualization allows multiple operating system at the same time.

• Traditional dual boot allows users to use only linux operating system meanwhile OS virtualization allows multiple operating system at the same time.

“Guest operating systems and applications don't need the full use of the underlying hardware.”

The implication of the above statement relates to:

• The virtualized guest operating systems and applications don't need to be fast

• The performance of the guest operating systems and applications is not stable

• The virtualized guest operating systems and applications don't need a separate hardware

• The performance of the virtual system is not equal to the performance of the operating system running on true hardware
