<A> Big Businesses <FEEDBACK> All of the following were early adopters of cloud computing when it was first developed except for big businesses. As time went on and cloud computing gained more recognition it was widely accepted by most businesses for many reasons covered in chapter 6.

<CHAPTER>#5 <STEM> Average Joes Tools is trying to bring itself into the modern era through cloud computing. They are a small business however and investing lots of money into this update is a risk. As a Computer Information Systems consultant you want to lower Average Joes Tools' worry. How might you convince them this is worth the investment? <A> Cloud computing follows a pay-as-you-go pricing model <B> Cloud computing increases effectiveness of governance and security <C> Customers have no expectations to have their needs met over the web <D>Cloud computing implementation is slow and can be monitored easily

<A> Cloud computing follows a pay-as-you-go pricing model <FEEDBACK> Cloud computing actually decreases effectiveness in governance and security, customers DO expect their needs to be over the web more and more, and cloud computing implementation is actually pretty fast. Therefore the only correct choice is A. This is true and has the added benefit of not involving a huge investment (which the small business was worried about).

<Chapter>4 <Stem>Which network would be best used for connecting networks across country? <A> WAN <B> LAN <C> BN <D> MAN

<A> WAN <FEEDBACK> LANs are used mainly for close-knit areas, such as an office floor or building. BNs connect multiple LANs to a MAN, which is used for networks that are semi-large such as JMU campus. WANs are the largest network and is what makes international connections possible.

<CHAPTER>6 <STEM> Which of the following is a more commonly used SaaS application? <A>CRM <B>TQM <C>EIS <D>BPR

<A>CRM <FEEDBACK> Customer Relationship Management models are more aligned with software as opposed to the others

<A> New technologies are always met with resistance <FEEDBACK> From the story of cloud computing, we know that the general public is always hesitant to adopt a new technology until it has been tested and perfected. There is much risk in rashly adopting a new technology before the advantages and disadvantages have been determined.

<CHAPTER> #5 <STEM> Which characteristic is NOT TRUE of cloud computing? <A> Security maturity lags because small businesses are the early adopters <B> The standards and best practices of cloud computing emerges over time <C> Early adopters and risk takers embrace the new technology of the cloud <D> The technology evolves and matures as adoption of the cloud increases

<A> Security maturity lags because small businesses are the early adopters <FEEDBACK> "A" is correct because security maturity lags due to enterprises being the late adopters not because small businesses are the early adapters. "B" "C" and "D" are all true characteristics of cloud computing

<CHAPTER>4 <STEM> What layers does the OSI model have that differ from the Internet Model? <A> Session and Presentation <B> Presentation and Transport <C> Data and Transport <D> Network and Application

<A> Session and Presentation <FEEDBACK> The two layers that the OSI model has that are different from the Internet Model are Session and Presentation. The internet model combines those into the Application layer.

<CHAPTER 6> <STEM> When speaking of clouds, the four types of deployment models are public, private, hybrid, and community. All of the following are major advantages of public clouds except: <A>Control <B>Utility Pricing <C>Core Competency <D>Elasticity

<A>Control <FEEDBACK>Control is one of the major disadvantages of public clouds. Utility pricing means users pay only for what they use. Elasticity means there is seemingly an endless pool of resources at the user's disposal. Finally, core competency means that users are outsourcing its data center and infrastructure management to companies whose core competency is managing infrastructure.

<CHAPTER>5 <STEM>Which of the following would not describe an advantage of public clouds? <A>Control <B>Elasticity <C>Core competency <D>Utility pricing

<A>Control <FEEDBACK>Utility pricing, Elasticity, and Core competency are all advantages of public clouds. Control is a disadvantage because end users must rely on public cloud vendors for performance and uptime.

<CHAPTER>4 <STEM>Which layer is in control of the physical layer by deciding when to transmit messages over the media? <A>Data Link <B>Application <C>Network <D>Transport

<A>Data Link <FEEDBACK> The layers in the Internet are often so closely coupled that decisions in one layer impose certain requirements on other layers. This is one example of how the data link layer and physical layer are closely tied together. These two layers are grouped together and are called the hardware layers

<CHAPTER>4 <STEM>What layer of the Internet Model is responsible for moving a message from one computer to the next computer in the network patch from the sender to the receiver? <A>Data Link Layer <B>Network Layer <C>Application Layer <D>Physical Layer

<A>Data Link Layer <FEEDBACK>The data link layer controls the physical layer by deciding when to transmit a message.

<CHAPTER>6 <STEM>What does the consumer manage and control in the Infrastructure as a Service (IaaS) model? <A>Deployed applications <B>Storage <C>Operating systems <D>Servers

<A>Deployed applications <FEEDBACK>Answers B, C, and D are all parts of the underlying cloud infrastructure, which the consumer doesn't control. The only things the consumer has control over are the deployed applications and sometimes configuration settings.

<CHAPTER>5 <STEM> A company wants to have a low cost, high scale and self-service capabilities for their system. Which of the following should they choose? <A>Enterprise clouds <B>Cloud computing <C>Commodity clouds <D>Software as a Service

<A>Enterprise clouds <FEEDBACK> Enterprise clouds are expensive and complex and can meet security, regulatory, and SLA requirements. Cloud computing combines the best of the mainframe era and PC-enable client server. It allows data to be online instead of having a physical database. Software as a Service is an on-demand software solution. (page 122)

<CHAPTER>4 <STEM>This type of server stores data and software that can be used by computers on the network. <A>File Server <B>Print Server <C>Web Server <D>SQL Server

<A>File Server <FEEDBACK>The print server is connected to a printer and manages all print requests, the web server stores information that can be accessed from a Web browser, and SQL Server is a relational database management system.

<CHAPTER>4 <STEM>What type of network would function best for the work the FBI does? (requires security limited to internal users) <A>Intranet <B>Extranet <C>WAN <D>LAN

<A>Intranet <FEEDBACK> Intranets are LANs with Internet technologies limited to those inside a specific organization. Extranets do not provide the level of security that an organization such as the FBI would require, as access can be provided to those outside the organization. LAN and WAN do not work, as LAN on its own does not support internet and WANs can be insecure without proper security settings.

<CHAPTER>5 <STEM>Which of the following is NOT an example of cloud computing <A>JMU email <B> Netflix <C> Instagram <D> Dropbox

<A>JMU email <FEEDBACK> the answer is JMU email because it is confined to JMU's network only.

<CHAPTER>#4 <STEM> As an IT professional you have to decide what type of network your company will use. All of the devices you are connecting are in the same building. What type of network is your best option <A>LAN <B>WAN <C>extranet <D>intranet

<A>LAN <FEEDBACK>Because all of the connected devices are located in close proximity the best option is to use LAN

<CHAPTER>4 <STEM>When considering a WAN network that spans large didstances, what method makes sense to use to connect the smaller LAN networks? <A>Lease Circuits from IXC's <B>Fiber Optics <C>Wires <D>Web Servers

<A>Lease Circuits from IXC's <FEEDBACK>Fiber optics and wires are really inefficient for long distances. Web servers are not a method but a tool.

<CHAPTER>6 <STEM>Advantages of the public cloud include all of the following, except: <A>Limited infrastructure configurations. <B>Extensive pool of resources available. <C>Pay-as-you-go pricing. <D>Outsourcing to experts in managing infrastructure.

<A>Limited infrastructure configurations. <FEEDBACK>The public cloud is not a great option for consumers who require specific hardware to resolve a problem. Each of the other options is an advantage of using a public cloud.

<CHAPTER>4 <STEM>Which layer in the internet model is responsible for determining the next computer a message should be sent? <A>Network Layer <B>Application Layer <C>Data Link Layer <D>Session Layer

<A>Networks <FEEDBACK> Infrastructure as a service grants customer access to virtual hardware- which includes storage, networks and processing

<CHAPTER>4 <STEM>Which layer does NOT help create a new Protocol Data Unit as the message passes through them? <A>Physical Layer <B>Data Link Layer <C>Network Layer <D>Application Layer

<A>Physical Layer <FEEDBACK>The message is created in the application layer, which creates the rules of HTTP, which defines a specific PDU. The network layer places it the TCP segment inside an IP PDU (IP packet), and passes the IP packet, which contains the TCP segment, which, in turn, contains the HTTP packet, which contains the message to the data link layer. The data link layers formats the message with start and stop markers, adds error checking information, places the IP packet inside an Ethernet PDU. The physical layer then takes the Ethernet PDU and sends it as a series of electrical pulses through your cable to the server (other methods of media can be used as well). It doesn't help create a PDU. (pg. 101-102)

<CHAPTER>#6 <STEM> A company stores data involving clients' SSN's, Addresses, and credit card information. Which deployment model of cloud computing services would NOT be considered a viable option? <A>Public <B> Private <C>Hybrid <D>Community

<A>Public <FEEDBACK>(pg. 135) Sensitive data should not be stored on the public cloud if it can be avoided.

<CHAPTER>6 <STEM>ABC Cookies is a small, family-owned bakery located in Harrisonburg, VA. The business has recently expanded and the owner is looking to purchase cloud computing resources to manage the company payroll, rather than keeping track of it himself in an Excel spreadsheet. Which type of resource should ABC Cookies use? <A>SaaS <B>IaaS <C>PaaS <D>NIST

<A>SaaS <FEEDBACK>Since payroll is not a core competency functionality of ABC Cookies, it makes sense for them to purchase an off-the-shelf payroll system, or IaaS. This way they do not have to support the application infrastructure or hire staff to manage it all.

<CHAPTER>4 <STEM>Which three layers of the OSI (Open Systems Interconnection Reference) Model make up the application layer of the Internet Model? <A>Session, Presentation, Application <B>Application, Transport, Internet <C>Transport, Network, Data Link <D>Network, Data Link, Physical

<A>Session, Presentation, Application <FEEDBACK> All of the layers between these two models are the same however the OSI Model just collapses these three layers into one layer. The Internet Model is the more frequently used model so our class focuses on this five layer approach instead of the seven.

<CHAPTER>4 <STEM>The IT company you work for needs you to plan and set up a network that connects together all of their offices around the world. What would you suggest? <A>WAN <B>BN <C>LAN <D>MAN

<CHAPTER> #4 <STEM> All layers of the Internet Model create a new PDU as the message passes through EXCEPT which layer? <A> Transport Layer <B> Physical Layer <C> Data Link Layer <D> Application Layer

<B> Physical Layer <FEEDBACK> "B" is correct because when at the Physical Layer it does not create a new PDU because it is the last layer that the message goes through before going from the sender's physical layer. "A" is incorrect because the Transport layer creates a new PDU as the message passes through to them and on to the Network Layer. "C" is incorrect because the Data Link Layer creates a new PDU as the message passes through to them and on to the Physical Layer. "D" is incorrect because the Application Layer creates a new PDU as the message passes through to them and on to the Transport Layer.

<CHAPTER>5 <STEM> It is smart for startups, such as Instagram, to want to design an app using cloud based security because they would rather focus on the user experience rather than managing data and hardware. Startups are uncertain about how fast or how big they will grow to be, so using cloud based security appeals to them because of ______________. <A> Productivity <B> Scalability <C> Availability <D> Workability

<B> Scalability <FEEDBACK> B (Scalability) is the correct choice as indicated on page 124. Scalability is a key feature for companies facing uncertainty about growth because they need something that can quickly adjust to meet their needs.

<C>Elasticity <FEEDBACK> With public clouds, the end user has the ability to configure software solutions to dynamically increase or decrease the amount of compute resources it needs to handle peak loads. This relates directly with elasticity.

<CHAPTER>6 <STEM>What advantage of public clouds allows the end user to react in real time to abnormal spikes in traffic? <A>Utility Pricing <B>Control <C>Elasticity <D>Core Competency

<C>Elasticity <FEEDBACK>Utility pricing allows the end user to turn on more cloud services when it needs to scale up and turn off when it needs to scale down. This advantage is directed towards no longer needing to procure physical hardware. The advantage of core competency allows the end user to spend more time focusing on its own core competency rather than the core competency of managing infrastructure where an outsource can focus on that. Control is a drawback of public clouds because the end users must rely on the public cloud vendor to meet their SLAs for performance and uptime. Elasticity is correct because the end user can configure its software solutions to dynamically increase or decrease the amount of compute resources it needs to handle peak loads. (pg. 134-135)

<CHAPTER>4 <STEM> Which server stores data and software that can be used by computers on the network? <A>Web Server <B>Print Server <C>File Server <D>Backbone network
