Virtualization and Cloud computing (1) Flashcards
Microsoft offers users free access to a cloud-based storage account. What is the name of the service?
OneDrive
WinCloud
Shadow Copy
OneDrive
CompTIA refers to this as two words (One Drive), but Microsoft refers to it as one (OneDrive). Either way, it is the online/cloud storage account that comes with your Microsoft account. You can save files there from applications or move them there (and back again) using File Explorer (previously called Windows Explorer). There is a limited amount of storage given to each account for free, and you can purchase more as you need it
What type of cloud service offers the best security?
Community
Private
Hybrid
Private
Companies can purchase virtualization software to set up individual clouds within their own network. That type of setup is referred to as a private cloud. Running a private cloud pretty much eliminates many of the features that companies want from the cloud, such as rapid scalability, and eliminates the need to purchase and manage computer assets. The big advantage, though, is that it allows the company to control its own security within the cloud. A hybrid model would be the scenario providing benefits of both public and private clouds. The community model is something akin to a shared private cloud, with responsibilities and benefits collaboratively shared among more than one organization
Your manager tells you to purchase cloud-based services. Your network needs extra processing power and file storage. What type of service should you purchase?
PaaS
IaaS
SaaS
IaaS
Let’s say that your company needs extra network capacity, including processing power, storage, and networking services (such as firewalls), but doesn’t have the money to buy more network hardware. Instead, you can purchase Infrastructure as a Service (IaaS), which is a lot like paying for utilities—you pay for what you use. Of the four, IaaS requires the most network management expertise from the client side. In an IaaS setup, the client provides and manages the software
Your company has decided to purchase cloud services from Google. What type of cloud does Google provide?
Public
Private
Community
Public
The traditional type of cloud that usually comes to mind is a public cloud, like the ones operated by third-party companies such as Microsoft, Google, HP, Apple, Netflix, and Amazon with its Amazon Web Services (AWS). These clouds offer the best in scalability, reliability, flexibility, geographical independence, and cost effectiveness. Whatever the client wants, the client gets. For example, if the client needs more resources, it simply scales up and uses more
You have recently connected your Windows 7 workstation to a cloud storage service. You want to ensure that the cloud-based service synchronizes with your desktop every morning at 2:30 a.m. Which Windows management utility should you use to enable this?
Task Scheduler
Event Viewer
Data Sources
Task Scheduler
The Task Scheduler (which may appear as Schedule Tasks in Windows 8.x Administrative Tools) allows you to configure an application to run automatically or at any regular interval. A number of terms are used to describe the options for configuring tasks: action (what the task actually does), condition (an optional requirement that must be met before a task runs), setting (any property that affects the behavior of a task), and trigger (the required condition for the task to run)
Your company produces software and employs about 20 developers. They need to program apps for different operating systems. You decide to purchase cloud-based services to support the development team. What type of service should you purchase so they can develop their programs and then test them in environments other than where they were developed?
IaaS
SaaS
PaaS
PaaS
Platform as a Service (PaaS) adds a layer to IaaS that includes software development tools such as runtime environments. Because of this, it can be helpful to software developers; the vendor manages the various hardware platforms. This frees up the software developers to focus on building their application and scaling it. The best PaaS solutions allow for the client to export its developed programs and run them in an environment other than where they were developed
Which type of cloud service provides your company with the network hardware, infrastructure, and software needed to run your business?
PaaS
IaaS
SaaS
SaaS
The highest of the four levels of cloud service is Software as a Service (SaaS), which handles the task of managing software and its deployment, and it includes the platform and infrastructure as well. This is the model used by Google Docs, Microsoft Office 365, and even storage solutions such as Dropbox
Which feature of cloud service allows you to instantly obtain additional storage space or processing power as your company needs it?
Rapid elasticity
Resource pooling
Measured service
Rapid elasticity
In most cases, clients can get more resources instantly (or at least quickly or on-demand), which is called rapid elasticity. For the client, this is a great feature because they can scale up without needing to purchase, install, and configure new hardware. Ubiquitous access refers to clients being able to access the cloud ubiquitously, or from anywhere, anytime. Resource pooling, particularly when a cloud provider deals with multiple tenants, refers to the provider effectively saving money by not duplicating available capacity. Finally, when service provided to those tenants is monitored and paid for according to their use, it’s measured service
You are configuring the Mail app on an iPhone to use an outlook.com email address. What configuration information do you need to enter to establish connectivity?
Email address and password
Email address and password, and server name
Email address and password, and server name, and mail protocol
Email address and password
When configuring a mobile email client to access a commercial email provider, you typically just need your username and password to establish connectivity. Examples include Google, Yahoo, Outlook.com, and iCloud
What feature of Windows 8 allows users to log into the OS, download apps from the Windows Store, and sync files to the cloud with only one sign-on?
Login sync
OneDrive
Live sign-in
Live sign-in
In a non-domain-based environment, it is possible to use your Microsoft account (MSN, Hotmail, Outlook, and so forth) username and password to log into your Windows 8–based PC. This is intended to serve as a single sign-on, allowing you not only to interact with the OS but also to download apps from the Windows Store, sync files with OneDrive, and so on
You are installing virtualization on a workstation that needs to support multiple operating systems. Which type of hypervisor is best suited for this environment?
Type 1
Type 2
Either Type 1 or Type 2 will function in the same way
Type 2
A Type 2 hypervisor sits on top of an existing operating system, called the host OS. This is most commonly used in client-side virtualization, where multiple OSs are managed on the client machine as opposed to on a server. The hypervisor is also called a virtual machine manager (VMM)
You are configuring client-side virtualization on an existing Windows 8.1 64-bit workstation. You will be running OS X Yosemite in the virtual environment. Each OS requires 2 GB of RAM. Windows needs 20 GB of disk space and Yosemite needs 8 GB. What is the minimum hardware requirements for this workstation?
4 GB RAM, 28 GB disk space
2 GB RAM, 20 GB disk space
4 GB RAM, 20 GB disk space
4 GB RAM, 28 GB disk space
If presented with a scenario for installing multiple operating systems on a computer running client-side virtualization, just add the minimum hardware requirements (or recommendations) together. Treat it as if each OS needs its own minimum (which it does) and they are just sharing the available physical hardware (which they are). Also, each OS needs its own virtual network card to participate on the network and needs its security to be individually configured based on OS requirements and user needs. Treat it as though it is a separate computer
You are setting up a virtualization on a server that will be running four instances of Windows Server 2012 R2. Four different departments will be using one instance each, and all departments have been promised 16 GB RAM. Using resource pooling and using a bare-metal hypervisor, what is the minimum amount of physical RAM needed on the server?
16 GB
32 GB
64 GB
64 GB
If each client has been promised 16 GB RAM, then the server must have enough RAM to give each client their allotment. This means 64 GB in this case. The assumption is that the hypervisor will require no RAM on its own. In reality, it probably will require a little but not much. Resource pooling, when a cloud provider deals with multiple tenants, refers to the provider having additional capacity available but saving money by sharing that availability
Your company has an application developer who creates programs for Windows, Linux, and MacOS. What is the most cost-effective solution for her to be able to test her programs in multiple operating systems as quickly as possible?
Set up her workstation to dual boot
Set up her workstation with virtual machines
Create one version of each application that will run in all three OSs
Set up her workstation with virtual machines
The major feature of virtualization is breaking down that one-to-one hardware and software barrier. The virtualized version of a computer is appropriately called a virtual machine (VM). Thanks to VMs, it is becoming far less common to need dual-boot machines today than in the past. VMs allow computers to do things like run five instances of an OS or one instance of several different OSs
For which operating system can you get a preconfigured virtual machine (that runs in the Windows Virtual PC emulator) that allows users to run Windows XP-based applications?
Windows Vista
Windows 7
Windows 8
Windows 7
The ability to run applications in Windows XP Mode (XPM) is included with Windows 7 Professional, Enterprise, and Ultimate. This is a virtual client (emulating Windows XP Professional with Service Pack 3), and you must download and install Windows Virtual PC to use it. XPM was discontinued in Windows 8/8.1, but Virtual PC is still Microsoft’s latest virtualization program for home-based platforms. Hyper-V can be used on business-end Microsoft platforms, including Windows 10 Professional, Education, and Enterprise
