A. 2080::8::200C B. 2080::0:8:0:0:200C C. 2080:0000:0000:0000:0008:0000:0000:200C D. 2080::8:0:0:200C E. 2080:0:0:0:8::200C F. 2080:0:0:0:8:0:0:200C Answer: D IPv6 addresses are represented as a series of 16-bit hexadecimal fields separated by colons (:) in the format: x:x:x:x:x:x:x:x. Following are two examples of IPv6 addresses: FEDC:BA98:7654:3210:FEDC:BA98:7654: :0:0:0:8:800:200C:417A It is common for IPv6 addresses to contain successive hexadecimal fields of zeros. To make IPv6 addresses less cumbersome, two colons (::) may be used to compress successive hexadecimal fields of zeros at the beginning, middle, or end of an IPv6 address (the colons represent successive hexadecimal fields of zeros). Table 2 lists compressed IPv6 address formats. A double colon may be used as part of the ipv6-address argument when consecutive 16-bit values are denoted as zero. You can configure multiple IPv6 addresses per interfaces, but only one link-local address. Note Two colons (::) can be used only once in an IPv6 address to represent the longest successive hexadecimal fields of zeros. The hexadecimal letters in IPv6 addresses are not case-sensitive.

QUESTION NO: 90 The West Ridge School District in North Carolina has approximately 2,800 students occupying five schools: three grade schools, one junior high, and one high school. All telephone service is handled by the local phone company. Every phone call is switched by the providers centrex switch, then routed to the appropriate school. Each school is networked with fractional T1 Frame Relay and Cisco routers. The users are on a switched 10/1/100 network utilizing Cisco switched and Category 5 cable. Internet access is through the high school which has an Internet connection through a provider 35 miles away via a T1 Frame Relay. The school district needs to put phones in each classroom for compliance with the Safe- Schools initiative, but the cost is high and facilities are lacking. In addition to the phones, the district would like to install video in each school for video conference and for distance learning in the high school. Video partners will be connected with ISDN PRI LINKS. There is also a need to protect the student information stored on local serves and shared between the schools are as students graduate from elementary school to junior high, and students transfer in and out of the district. Which two are advantages of suggesting IP telephony to this customer? (Choose two) A. Voice, video and data run on the same Cat5 cable. B. Long distance charges can be reduced by running VoIP. C. All reliance on the local phone company can be eliminated. D. The cost of adding additional telephones is minimal. Answer: A, D A. In a converged network, voice, video and integrated data runs on the same physical media. D. The cost is reduced and minimized by requiring less from the telephone service provider. Incorrect: B: Chapter 17, CCDA Exam Certification Guide: Page 435 The introduction of packet-voice technology allows the convergence of data and voice networks --- which lets companies save toll charges on voice telephone calls and reduce their total cost of ownership by not having to build and operate networks for voice, video, and data. Long distances charges are reduced when the remote site is part of the IP network. In this case, the schools are part of a local school district and any long distance calls would not apply to this rule. C: Calls that are placed between offices through the private voice network are called on-net. If a user needs to place a call outside the private network, the call is routed to the local PSTN. If the call is forwarded to the PSTN, it is called off-net. Because not all calls are point to point the need for local company still exists

Subnetworks are assigned by Public Authorities C. Subnetworking is not allowed in IPv6 D. IPv4 compatible IPv6 addresses E. Subnetworks are assigned by Internet Service Providers Answer: A The aggregatable global address typically consists of a 48-bit global routing prefix and a 16- bit subnet ID or Site-Level Aggregator (SLA). In the IPv6 aggregatable global unicast address format document (RFC 2374), the global routing prefix included two other hierarchically structured fields named Top-Level Aggregator (TLA) and Next-Level Aggregator (NLA).The IETF decided to remove the TLS and NLA fields form the RFCs because these fields are policy-based. Some existing IPv6 networks deployed before the change might still be using networks based on the older architecture. A 16-bit subnet field called the Subnet ID could be used by individual organizations to create their own local addressing hierarchy and to identify subnets. A subnet ID is similar to a subnet in IPv4, except that an organization with an IPv6 subnet ID can support up to 65,535 individual subnets.

65 B. Routers convert OSPF to IS-IS for IPv6 C. There is no change in OSPF between IPv4 and IPv6 D. OSPF can not be used with IPv6 E. There is a new version of OSPF for IPv6 Answer: E OSPF is a routing protocol for IP. It is a link-state protocol, as opposed to a distance-vector protocol. Think of a link as being an interface on a networking device. A link-state protocol makes its routing decisions based on the states of the links that connect source and destination machines. The state of a link is a description of that interface and its relationship to its neighboring networking devices. The interface information includes the IPv6 prefix of the interface, the network mask, the type of network it is connected to, the routers connected to that network, and so on. This information is propagated in various type of link-state advertisements (LSAs).

A dozen stock traders will require constant data access to exchange all around the world. This access must be fast and without interruption. Which two feature can help you provide this level of connectivity? (Choose two) A. CDP B. IGRP C. CoS D. QoS E. GoS Answer: C, D This document describes Quality of Service (QoS) for Voice over IP (VoIP) in a LAN environment by mapping Type of Service (ToS) to Class of Service (CoS) parameters. Until recently, the general consensus was that QoS would never be an issue in the enterprise side due to the bursty nature of network traffic and the capability of buffer overflow. The reason for QoS on the LAN side is due to buffering, not lack of bandwidth. For this reason, QoS tools are required to manage these buffers to minimize loss, delay, and delay variation. Transmit buffers have a tendency to fill to capacity in high-speed networks due to the bursty nature of data networks combined with the high volume of smaller Transmission Control

66 Protocol (TCP) packets. If an output buffer fills, ingress interfaces are not able to immediately place new flow traffic into the output buffer. Once the ingress buffer fills, which can happen quickly, packet drops occur and this is where voice quality may possibly degrade due to packet loss.

Both modules employ access control to filter traffic, although the edge distribution module can rely somewhat on the entire edge functional area to perform additional security functions. Both modules use Layer 3 switching to achieve high performance, but the edge distribution module can add additional security functions because the performance requirements are not as great. The edge distribution module provides the last line of defense for all traffic destined to the campus module from the edge module.

A small window size will reduce the number of retransmissions C. A small window size would improve performance D. there is not enough information to determine the effect window size Answer: A Some protocols, such as Novell s traditional NetWare Core Protocol (NCP), use a pingpong approach, where each request generates a reply. This a approach is an inefficient use of bandwaidth, but it can be replaced by the burst mode protocol. With burst mode, a station can send as much data as there is room in the reciever s receive window. In the TCP/IP suit, the TCP supports windowing and flow control.

68 C. IPv6 address cannot use route summarization D. IPv6 address have built in router summarization based on Top level aggregators, Next Level aggregators and Site Level aggregators E. The routers in the IPv6 network use proprietary protocols to optimize router summarization based on the size of their routing tables Answer: D In addition to required protocols, infrastructure address space needs to be identified since this is the space the ACL will be protecting. Infrastructure address space includes any addresses that are used for the internal network and should rarely, if ever, be accessed by external sources such as router interfaces, point-to-point link addressing and critical infrastructure services. Since these addresses will be used for the destination portion of the infrastructure ACL, summarization is critical and, wherever possible, these addresses should be grouped into classless interdomain routing (CIDR) blocks.

Broadcasts can be controlled through the use of VLANs C. Routers do not forward broadcasts D. Broadcasts don t occur at Layer 3 Answer: B, C QUESTION NO: 161 TestKing operates a chain of 50 video rental shires located in the Europe. They currently have a Point-of-Sale (I'OS) system in which each store posts its daily sales data and inventory changes to a central database through dial-up communication. There is no interaction between the stores and the central system during business hours. The central site runs on an Ethernet LAN. The only always-on WAN link is an Internet connection using wireless broadband to a local ISP. TestKing wants to enhance their service offering by creating a new E-Commerce web site where customers can browse and search a catalog of video titles and select the ones they want for rental. The system will instantly communicate the order to the nearest store where employees pull the order and hold it until the customer picks it up. The service must operate on a 24x7 basis. TestKing sees this new business strategy as a means to increase revenue and expand the business nationally. They see an opportunity to expand the web site in the future to video, DVD and music sales on a worldwide level. The company wants all stored to be connected to the central site through WAN links. The company is upgrading the central inventory database so that sales and rentals can be posted immediately in real-time. An Internet-based and instant-messaging system will be set up for all headquarters employees and store managers to use. TestKing believes that networking the stores will improve order fulfillment processes which will improve customer satisfaction and thus, boost revenue. It will also help communication with store employees. TestKing wants to upgrade the local LAN to a Gigabit and Fast Ethernet system to facilitate the demands of the new and upgraded systems. They have budgeted $500,000 for the networking equipment and another $10,000/month for the WAN charges including a faster Internet connection. They believe that 256Kbps speeds will be adequate to the stores. Since they have no staff capable of managing the new network, they will hire two engineers that already have the training and experience. The project must be complete in 6 months when the new inventory system goes online. The IT manager has concerns about the security of the servers and workstations on the network when all stores become connected. He doesn't want any Internet access to or from the stores. He is depending on you to recommend an effective yet affordable solution that will protect his system from intruders. Which two are business constraints imposed by the TestKing Video Company on this new network design project? (Choose two)

88 Section B Practice Questions CASE 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, , 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 8 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 . In the San Jose office, FSI has two LANs with 80 PCs. The main LAN has 5 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

89 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 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 4 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 3 Orchard Leasing Corporation: Office building leasing and facilities management

90 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 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

91 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 , 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 , 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 5 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 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 5 Macintoshes (for production of marketing material and product

92 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.
