Quiz 4 cloud computing

Identify which statement is TRUE about a bare metal hypervisor?

• It can only be hosted on an existing operating system.

• It requires a separate license for the native operating system

• It has minimum functionality to support only one type of operating system

• It runs directly on server hardware to provide virtual machines with timesharing resources.

Based on the statement s below, select the BEST description of hypervisor?

• Act as filters the messages that are getting exchanged between the networks.

• It is used to protect the sensitive data from professional hackers and other spammers who are usually remain active to get the data

• Known as virtual machine monitor (VMM) that manages resources for virtual machines

• Hypervisor focus on a few layers like cloud application, infrastructure providing and providing platform markets.

Select the best statement describes the relationship between application, server, and client in a multi­tenancy environment?

• Single instance of software running on a server and serves one client

• Single instance of software running on a server and serves multiple clients.

• Multiple instances of software running on a server and serves multiple clients.

• Multiple instances of software running on multiple servers and serves one client.

A company gathers, stores, manages, and protects data as part of its business. How can it create business value from the data?

• Create a virtualized server infrastructure

• Create a virtualized application infrastructure

• Create a virtualized information infrastructure

• Create a virtualized end user / client infrastructure

Select the INCORRECT match between virtualization technology and its respective software

• Full Virtualization – KVM

• Full virtualization – Vm Ware

• Full virtualization – HyperV

• Full virtualization – Linux

Choose the scenarios that need virtualization software.

• A client needs to run one operating system at a time.

• A company needs an application to reduce hardware and electricity costs.

• A company needs to additional costs and configuration complexities when upgrading the hardware.

In creating a new virtual machine, by using a virtualization software, a user is able to do following EXCEPT:

• hardware settings such as how much memory the VM should have.

• what hard disks should be virtualized through which container files and what CDs are mounted,

• devide the operating system into multiple versions based on latest update.

• state information whether the Virtual Machine is currently running and saved its snapshots.

Choose the benefits of server consolidation with Microsoft Hyper-V:

• improved server utilization rates.

• larger physical servers in your data center

• decreased power and cooling costs per physical server

• upgrading the server OS on a host machine

Process of creating a virtual environment on an existing server to run your desired program, without interfering with any of the other services provided by the server or host platform to other users referred as:

• Isolation

• Virtualization

• Encryption

• Encapsulation

Define the role of virtualization in cloud computing?

• It removes operating system inefficiencies

• It improves the performance of web applications.

• It optimizes the utilization of computing resources.

• It adds extra load to the underlying physical infrastructure and has no role in cloud computing.
