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
