Network Consultant Scenario You have been contracted to build a network for a multimedia development firm that currently uses a 10-Mbps Ethernet network. The company requires a high-bandwidth network for the multimedia team, which constantly views and manipulates large files across the network. The company is expecting moderate growth. You are to come up with a solution to support the high-bandwidth applications and growth potential of this company. Required result: ¦ Increase network bandwidth. Optional result: ¦ Support future growth. Improve server response time. Proposed solution: ¦ Install CAT 5 UTP cable in a star topology with the existing hub. ¦ Upgrade the workstation’s adapter cards to support 100 Mbps. ¦ Increase the amount of RAM in the server.The proposed solution ___________. a. achieves the required result and both optional results b. does not achieve the required result but achieves both the optional results c. does not achieve the required result but does achieve one of the optional results d. achieves the required result but cannot achieve either of the optional results e. chieves neither the required result nor either of the optional results Ans:Correct answer should be e. achieves neither the required result nor either of the optional results the result the firm wants to achieve is to Increase network bandwidth. Optional results are, the solution proposed should support future growth and improve server response time. The proposed solution does not meet any of the above mentioned requirements. Though CAT-5 cable supports up to 100 Mbps, it will not improve the network bandwidth significantly. Bottleneck will be Hub.Instead of Hub, firm should put switch which will decrease collision. If it is layer-3 switch, VLAN can also be configured which will improve response time and network performance. Similarly, this solution does not support future growth. In fact, futuristic solution would suggest use of CAT 5e cable, Layer-3 switch, server farm. Using router would give better result, but since firm is witnessing moderate growth only, we can rule out the use of router for time being as it is a costly solution. Increasing RAM of servers is not a solution but ad-hoc measure.Performance of server depends on so many things including processor speed, quality of network, memory etc. Increasing RAM is only a try. Instead firm could create a server farm. When a hub receives a packet of data, it transmits the packet to all of its ports and, thus, to all of the other network equipments on the network. If two or more PCs on the network try to send packets at the same time a collision occurs, which detoriates the network performance. Switch break-up collision domain. So, it will give improved network performance.Also, a layer-3 switch can be used to configure VLAN which will improve the network performance dramatically as packets can be restricted inside own virtual LAN. Use of CAT 5e cable will help the firm in future when firm can put equipments supporting higher bandwidth and goes for network revamping. Otherwise firm will have to lay the cable again. A server farm is a group of computers acting as servers and housed together at a same place. It helps the firm in maintaining the particular location (like cooling). Server farms are typically co-located with the network switch which improves the server response.
