Name: __________________________ Date: _____________1. Which of the following is not a step under the traditional network design approach?A) An analyst develops cost estimates of the circuits needed to support the network.B) An analyst takes the traffic on the current network and then multiplies that by a factor of 3.65 to come up with the estimate of the total traffic for the new network.C) An analyst meets with users to identify user needs.D) An analyst develops a precise estimate of the amount of data that users will send and receive to estimate the total amount of traffic on each part of the network.E) An analyst designs the circuits to support the estimated traffic, allowing for modest growth.2. The traditional network design approach does not work well for _________ networks.A) slowly evolvingB) rapidly growingC) staticD) modestly growingE) not growing3. Which of the following is not making the traditional design approach less appropriate for today's networks?A) The underlying technology of networking devices is changing very rapidlyB) The underlying technology of client and server devices is changing very rapidlyC) The underlying technology of circuits is changing very rapidlyD) Growth in network traffic is very highE) The most expensive part of any network is the hardware4. Which of the following is not contributing to the dramatic increase in network traffic today?A) Video applications on networks are becoming common.B) Electronic mail is now used by most people who work in organizations.C) Web searches are now commonly performed by network users.Page 1D) Client computers today can have 512 RAM, a 60 Gb hard drive, and 1.86 Ghz processors.E) Multimedia applications on networks are becoming common.5. Which of the following is false about staff costs for a network?A) The most expensive part of the network today is the staff who design, operate, and maintain itB) The emphasis is on network designs that reduce staff time needed to operate themC) Network staff are often required to learn to operate a variety of devicesD) Network staff are often required to maintain a variety of devicesE) When a variety of devices are used in a network, it takes less time to perform network management activities6. The building block design approach is sometimes called:A) wide and shallowB) narrow and deepC) wide and deepD) narrow and shallowE) narrow and flat7. Nowadays, most organizations use a simpler approach to network design called the ___________ approach.A) building-blockB) frame definitionC) prototypeD) systems development life cycleE) guided network8. Which of the following is not a step that is used in newer type of network design process?A) cost assessmentPage 2B) technology designC) implementationD) needs analysisE) none of the above is a correct answer9. In __________, the network designer attempts to understand the fundamental current and future network needs of the various users, departments, and applications.A) technology designB) needs analysisC) narrow and deep analysisD) cost assessmentE) distribution layering10. In __________, the network designer examines the available technologies and assesses which options will meet the users' needs.A) technology designB) needs analysisC) narrow and deep analysisD) cost assessmentE) distribution layering11. In __________, the network designer considers the relative cost of the technologies.A) technology designB) needs analysisC) narrow and deep analysisD) cost assessmentE) distribution layeringPage 312. Which of the following is not true about network design?A) In designing LAN networks, network designers tend to err on the side of building too big a networkB) In designing BN networks, network designers tend to err on the side of building too big a networkC) In designing WAN networks, network designers tend to err on the side of building too small a networkD) In designing LAN networks, network designers tend to err on the side of building too small a networkE) In designing MAN networks, network designers tend to err on the side of building too small a network13. In needs analysis:A) a great deal of the work has probably never been doneB) the goal is to understand what users and applications the network will supportC) the geographic scope is not an important considerationD) a baseline of current operations is not importantE) the rate of growth of network traffic is not an issue14. Gaining an understanding of the current application system and messages provides a _________ against which future design requirements can be gauged.A) backplaneB) baselineC) turnpike documentD) wish listE) RFP15. The goal of the needs analysis step is to produce a ___________, or a statement of the network elements necessary to meet the needs of the organization.A) building blockB) access layerC) core layerD) cost assessmentPage 4E) logical network design16. Which of the following is not a conceptual part, or layer, of the geographic scope of the network?A) core layerB) application layerC) access layerD) distribution layerE) the layer that connects the different distribution layers to each other17. Which of the following is not a basic level of the geographic scope of the network?A) local area networkB) focused area networkC) backbone networkD) metropolitan area networkE) wide area network18. Which of the following would not be collected by a designer, working in the needs analysis phase, who was documenting general information and characteristics of the environment in which the network must operate?A) local laws that could affect the networkB) international laws that could affect the networkC) federal laws that could affect the networkD) building codes that could affect the networkE) traffic laws that could affect the network19. __________ is not an important consideration when network designers review old and new applications.A) Reviewing the NFL scoresPage 5B) Reviewing the organization's possible changes in product mixC) Understanding the organization's strategic plansD) Understanding development plans for new uses of electronic commerceE) Reviewing the organization's projections of sales20. Which of the following is not an example of identifying protocols that are needed to support hardware and software requirements of applications that will use the network?A) an application will use HTTP over TCP/IPB) an application will run on an IBM mainframe and so the network will require SNA trafficC) an application will need a gateway to translate SNA traffic into
