1: FSI Test Equipment Incorporated: Precision test equipment manufacturing FSI manufactures high-end, high-volume semi-custom test equipment Though the company only employs 150 people, sales revenue and profitability are very high because of niche market control and product price levels Each piece of equipment is built to order and goes through rigorous testing and integration As a result of market dominance, growth and profitability, company management has decided to make an initial public offering (IPO) of its stock FSI has customers through out the world Because their equipment integrates so tightly with customers’ high tech manufacturing systems, the company in reality becomes a partner with its customers during the design, manufacturing, and testing of the equipment Purchase order to operational date cycles are typically one year and approximately five systems are in the development cycle at any gives time Timely, accurate, and secure communications with the customer throughout the cycle is in imperative Hardware design involves a significant number of CAD drawings to be stored and transmitted Software development requires hundreds of thousands of lines of code for each customer Though much of the code is reused, it nonetheless requires configuration and revision control for each customer With funds raised from the IPO, FSI wants to improve its ability to interface, communicate and respond to its customers It wants to implement secure FTP of code and drawings to its customer Security is of utmost importance and therefore FSI is not sure if can trust the Internet to accomplish these transfers Because of financial concerns, the company would much prefer the Internet to a private network if it can be convinced that the transfers can be made secure Otherwise it will consider a private network The company also would like to implement an inter-company workflow system for routing of electronic forms between FSI and its customers world-wide Again, security is the issue It would be wonderful if they can use the Internet for both these functions, but the new board of directors must be convinced FSI offices are in San Jose, California The project team assigned to customers has two sub-teams: the manufacturing and development team in San Jose, and the integration teams moves on site to the customers’ facilities Communication is by telephone, e-mail, and even overnight package delivery 25% of FSI employees (38-40) people are housed at customer sites at any given time These field persons are in teams of approximately people A Novell PC LAN on Ethernet is established for each team within the customers’ facilities with a dial-up Internet connection using Livingston router for e-mail In the San Jose office, FSI has two LANs with 80 PCs The main LAN has sun AutoCAD workstations that will use the test software, 20 Pentium UNIX engineering workstations for software development on one segment, and 50 office automation desktops running the Lotus Suite on another segment These two LAN segments are connected to a Novell server with the two Ethernet cards as the only routing mechanism between the two The second LAN has five processes monitoring an analysis PCs that collect and analyses the test data This data is accesses continuously by the engineering staff from their workstation The two LANs are networked with a third Internet card in the Novel server Engineering staff is frequently frustrated with the performance across this link You have been asked to provide a design and justification for an intranet/Internet bases solution that will convince the board of directors that the solution is viable and secure CASE 2: EIC Satellite Systems: Digital satellite television programming sales EIC sells minidish satellite systems and television programs in central Europe Its sales network comprises 10 company owned offices, 25 distributed sales and installation offices www.correctexams.com - 3- Fast Way to get your Certification and a central office in Milan, Italy In the central office 75 representatives provide 24 hour telephone support and order processing for programming changes There are 200 employees in the central office with PCs running Microsoft Office in addition to telephone representatives The company’s order processing, billing, accounting and programming systems reside on a large AS400 system in Milan The 10 company offices are connected to this system with 9600bps leased lines 25 distributor offices dial in to the system twice a day to upload order and download installation work order An Ethernet LAN with three Novel servers supports the 275 central office employees On average, the 10 offices have PCs connected via Ethernet with Microsoft Windows 95 The leased line in each office does not provide a touted connection but a serial connection of 5250 terminal emulation to the communication port on the PC The 25distributer offices dial in to the three PC Anywhere remote control computers that run 5250 terminal emulation and scripts that download installation work orders and upload new account orders to the AS400 To reduce transaction processing coast EIC will implement intranet technology to replace the current data communication mode A Web server will be installed on the AS400 with backend CGI that will interface to the order processing, billing and work order system Java applets will be built for both remote PCs EIC anticipates that these changes will allow it to handle twice the transactions without upgrading the AS400, while maintaining current transaction processing times The company offices will be connected via ISDN routers using bonding between channels for the new browser-based applications Similar browser-based connections will be accomplished for the distributor offices using a direct dial to the EIC Milan main office Unless convinced otherwise, EIC intends to use the existing 9600bps lines for the routed connections It is also desirable to provide an in Internet dial-up connections for customers to make their own configuration changes online and to order pay-per-view programming Security for these transactions will be provided by secure Web transactions Data transmission encryption is not necessary because these basically are secure Web-based credit card transactions EIC would like a design and proposal from you to provide the networking for this new architecture that must be implemented in parallel with current operations CASE Orchard Leasing Corporation: Office building leasing and facilities management www.correctexams.com - 4- Fast Way to get your Certification Orchard Leasing is a contract leasing and facilities management company with headquarters in Denver, Colorado and offices in Houston, Texas, Atlanta, Georgia, Minneapolis, Minnesota, Chicago, Illinois Orchard contracts with owners to provide leasing, maintenance and management of high-density office buildings and building complexes A local office is maintained in one building in each of the cities The company’s superior service and creative and aggressive marketing has lead to very rapid growth in each of the Orchard’s marketplaces In fact, Orchard has just signed contracts for four buildings in London, England and three buildings in Frankfurt, Germany However this growth has out stripped Orchard’s ability to keep up with administrative tasks associated with business, and management is very concerned about its ability to continue to provide the same level of service, given the two new international contracts Each of the offices has historically maintained its own operation center including a Windows NT file server with leasing, marketing, maintenance, and facilities management (including billing) software, as well as standard office productivity software provided by the WordPerfect suite The business applications are all custom are all custom applications developed in Access and Visual Basic Each office has an Ethernet network on 10BaseT cabling The leasing and marketing software systems run on Apple Macintosh and maintenance and facilities management runs on Intel-based PCs Typically, there are five PCs and two Macintoshes in an office The Denver office has six PCs and three Macintoshes but will increase those numbers to ten PCs and six Macintoshes after the proposed upgrades Data is consolidated monthly in an office report sent by e-mail via the Internet to the home office in Denver This Internet connection is by way of local ISP on a dial up connection With the addition of the London and Frankfurt offices, Orchard had decided to consolidate a www.correctexams.com - 5- Fast Way to get your Certification significant portion of administrative tasks in Denver The lease administration, tenant billing, accounts receivable accounts payable, and master building records will all be consolidated in Denver The marketing, maintenance, and office productivity software will continue to reside in the branch offices The number of computers, servers and Macintoshes and PCs will remain the same as the branch offices but a new NT Server and the additional Macintoshes and PCs will be added in Denver With this upgrade, Orchard will add Microsoft’s Exchange with outlook for e-mail, scheduling, and contact management The current branch office files servers will have less of a load and therefore Orchard believes they will be able to run Exchange Server and the existing server hardware with additional memory and disk space Additionally, Orchard will be establishing a World Wide Web site in Denver to be used for marketing and communication to tenants Orchards new chief financial officer (CFO), who has responsibility for computer and information systems, has requested competitive bids for a turn-key WAN to meet Orchards needs High performance across a WAN is not seen as a priority The communications that will occur between offices are “back-office” functions and are not time critical Accomplishing the transmissions this morning rather then tomorrow is the level of criticalness Minimising cost will take priority over unneeded performance The CFO estimates that beyond e-mail, which will be normal, there will be a daily transmission of records for consolidation both to and from each office and Denver each day These documents are approximately 2MB in size CASE 4: Leviathan System’s Inc: Business software development, publishing, and sales Traditionally, Leviathan has developed and sold AS400 business software solutions In addition to its headquarter office, it had five sales offices in United States, a European office, and an Asian office It is converting its software to Windows NT client/server technology using SQL Server as the database engine for the new project line The offices are connected with a point-to-point SNA network with line speeds varying from 56k to a Frac T1 Token Ring is installed within the office for LAN applications Each of the facilities is wired with Category cable in an Intermediate Distribution Facility/Main Distribution Facility (IDF/MDF) design The company recently decided that it must completely convert the Token Ring to Ethernet This conversion will first occur in the HQ facility and then in each of the branch offices The conversion will occur one IDF at a time, that is, the Token Ring and Ethernet networks will coexist as work groups are converted The client-server products will be added, but the AS400 product line will not go away Therefore, SNA will be a fact of life for the foreseeable future The customer prefers to have a single WAN but has decided to look at a frame relay solution to transport the client/server traffic and keep the SNA network intact Some TCP/IP is in use, but only at the local LANs The AS400s are connected to the Token Ring via a 5294 controller that provides the terminal server functions between the LANs and the AS400 Leviathan considers it too expensive and problematic to put the AS400 on Ethernet, so management would consider maintaining the AS400 on a small, four -node Token Ring network and put the rest of the company in Ethernet There are 56 5250 terminals in the HQ office and the sales office, each has approximately 6PCs running 5250 terminal emulation, including the Europe and Asia offices The 5250 terminals will be converted to PCs using the 5250 terminal emulation software The HQ office also had 100 PCs and Macintoshes (for production of marketing material and product www.correctexams.com - 6- Fast Way to get your Certification documentation) Additionally, there are two notebook computers in each sales office These notebooks already use terminal emulation to dial into the AS400 for demonstrations and sales reporting This dial-in functionality must continue to exist for the AS400 and must be provided for the new client/server products There are four AS400 at the HQ office facility and one each in two if the US sales offices, the European office, and the Asian office Four Windows NT servers will be located at HQ, and a small NT server in each of the sales offices Most of the 100 PC’s in HQ run 5250 terminal emulation, which utilizes NEtBIOS Two NT Servers are at HQ Two additional servers will be installed for a total of four Windows NT Servers, two for development (a Digital Equipment Corporation Alpha and a Hewlett-Packard multiprocessor Pentium), one for Sales and Marketing, and one for all other support Software development traffic to the AS400 occurs around the clock but peaks from to p.m The development effort on the new product is expected to follow the same pattern 15 new employees will be hired for this development effort All other use of the network occurs in normal business hours Leviathan will install an Internet server hosted on an additional Windows NT system It will provide a World Wide Web presentation of Leviathan products and an FTP server to deliver product updates and fixes It will also host a discussion group system and SMTP and POP3 servers for e-mail to customers and prospects The site must provide secure FTP and a firewall to protect Leviathan internal systems Leviathan has standardised Microsoft Office for office productivity and Microsoft tools for development of its new product line Company email is provided by a system on the AS400 This system will be converted to Microsoft Exchange, but not as a part of this project The IS manager has asked for a design to connect all the offices to provide the Ethernet connectivity within the HQ office and to provide for the Internet firewall Q.1 ISDN networks supports both _ A B C D Synchronous and ADSL modems Toll-connecting trunks and tie trunks Terminal handlers and external PADs Network termination
