.5 Describe some benefits of implementing a network management solution.Ms.Phillips described her staff as having moderate networking skills.There will bea substantial implementation of new technology, such as Internet security, newrouting, and new applications.The network support people will have to be trained tosupport the infrastructure.Therefore, a well-planned centralized networkmanagement solution would have the following results: Cost savings on having to hire new support staff because the IT personnel atremote offices can be supported by more experienced staff located in centraloffice. Diagnosis of problems would be more effective. Network management can support proactive monitoring to address possibleissues before affecting users. Increased productivity would result due to a more reliable network. Increased devices could be supported with the same number of IT personnel. Travel costs would be reduced for sending experienced IT staff to remote offices. The solution would be scalable for additional offices.

CH01.book Page 65 Friday, January 7, 2000 5:35 PMC H A P T E R3Application ConsiderationsThe purpose of this chapter is to review the different types of applications that a networkarchitect should consider when designing a network.Some network application familiescannot be routed; others can.The network must provide a way to transport the traffic acrosswide-area network (WAN) links.Some network operating systems produce broadcasttraffic that can be filtered.A CCDA must be able to identify the types of applications yourclients use and must understand how those affect the network design. Do I Know This Already? QuizThe questions in the following quiz are designed to help you gauge how well you know thematerial covered in this chapter.Compare your answers with those found in Appendix A, Answers to Quiz Questions. If you answer most or all the questions thoroughly andcorrectly, you might want to skim the chapter and proceed to the Q&A and CaseStudies sections at the end of the chapter.If you find you need to review only certainsubject matter, search the chapter for those sections that cover the objectives you need toreview, and then test yourself with these question again, as well as with the Q&A and Case Studies questions.If you find the following questions too difficult, read the chaptercarefully, until you feel you can easily answer these and the Q&A and Case Studies questions.1 In which bridging environment does the frame contain the routing information to thedestination?_________________________________________________________________________________________________________________________________________________________________________________________________________2 Which scheme provides a way to automatically assign IP addresses to devices on thenetwork?_________________________________________________________________________________________________________________________________________________________________________________________________________ CH01
