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.

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.

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.

Current Network Infrastructure Parnell Aerospace Client/Server LAN Diagram

Proposed Plan1. Upgrade the DC to Win2k Advanced Server and name

it to parnellaerospace.com2. 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.

Answer & JustificationQuestion 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

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

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

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)

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

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.

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

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.

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.

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.

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.)
