2. Introduction  Is a design and manufacturing company that creates guidance system for aircraft and rockets.  There are two buildings located in this company.  200 people works in the building 1 and 75 people works in building 2.

3. Existing Problem  Cost of ownership for existing network environment are high  Business partners are not able access to local network.  Difficulty in managing IBM Hardware.  Computers configuration are not automatic and fault tolerant.  Current OS is not robust enough  Two different protocol increase network overhead.

4. General Requirements  Minimize the cost ownership and improves productivity.  Improve the manageability by reducing the amount of administrative work.  Provide redundancy for fault tolerance.  Interoperability between 2 different networking topologies.  Minimize network traffic.  Enable Business partners to access local network for joint projects with strongest encryption capability.  Flexibility of future enhancement.

7. Proposed Plan 1.Upgrade the DC to Win2k Advanced Server and name it to parnellaerospace.com 2.Upgrade WinNT Server to Win2K Advanced Server and function as member servers in parnellaerospace.com domain. 3.Upgrade client computers to Win2K Pro. 4.Install Microsoft SNA server 4.0 on new member servers. 5.Install SNA Client software on the client computers. 6.Install Routing and Remote Access on the member server running on SNA Server. 7.Decommission the 3174 cluster control units and token ring bridge.

8. Network Infrastructure Proposal

9. Answer & Justification Question 1: You need to design an initial test model for Internet access. No external traffic can be allowed into the network and administrators need to control which websites internal users can gain access to. Which technology should you use. Answer: Proxy Server Justification: It acts a firewall component It provides access control to the network It secures the network

10. Question 2: What is the minimum number of IP-subnets you will require in your new network design? Answer: 3 IP-subnets Justification: SNA Network Building 1 Building 2

11. Question 3: You need to design the DHCP strategy for PA. What should you do? Answer: On each building place a DCHP-server. Set scope configured for each subnet in the network. Justification: Improve the manageability and availability of the client/server network

12. Question 4: You need to implement a network routing strategy for PA. What should you do? Answer: Performs static routing Justification: Decrease traffic in this large network W2K doesn’t support RIP(Dynamic routing)

13. Question 5: Which factor poses the greatest risk to your Windows 2000 deployment plan? Answer: Disruption of SNA application access Justification: SNA Server generates a Dr. Watson error in SNABASE.EXE when it receives an invalid message over a Named Pipe connection from a client. The SNA Server also logs an Event ID 624 in the Windows NT Application Log

14. Question 6: You need to allow external partners dial-in access to resources on the network. What should you do? Answer: For strong encryption on all connection, implement: –MS-CHAPv2 –MS-CHAP Justification: Provided strongest secure connection and it will only allow authorized users dial-in the network.

15. Question 7: What is the minimum number of DNS-Servers you should use in your new network? Answer: Two DNS servers Justification: For better network performance since current network seems very slow

16. Question 8. Which two factors should you consider in your new network design? Answer: Interoperability with the existing environment Remote connectivity Justification: IT manager requests the improvement between the two different networking topologies. The business partners needed to remote access to the mainframe or network.

17. Question 9. What are the two most critical problems in the current network? Answer: The network is difficult to manage and monitor. There is too much downtime. Justification: As system administrator request to improve the manageability and availability of the network. He and users want to reduce the network overhead and process faster.

18. Question 10. What is the minimum number of Wins-Servers you should use in the network? Answer: Two Wins-Servers Justification: Because there are two subnets.

19. Question 11. You are designing the initial placement of network services at Parnell Aerospace. Move the appropriate services to the appropriate building location or locations. (Use only network services that apply. You might need to reuse network services.) Building 1Building 2 DHCP DNS WINS Global Catalog Dial-Up Server
