The busy group started complaining because of the slow network performance. The network was operating at 50% utilization, whereas 30% utilization is acceptable. If you are the Information Technology Engineer of the corporation and have to resolve the problem technically. Question : 1) Describe four choices for resolving the problem maintaining the lan as Ethernet Lan. 2) State the advantages of each approach. 3) State the disadvantages of each approach. 4) Give reasoning about the choice you would prefer. AN ISO 9001 : 2008 CERTIFIED INTERNATIONAL B-SCHOOL
  • 2. CASE STUDY : 2 Assume these are two management stations – one SNMP based and the other Corba based. The SNMP based manager does poll based fault management of a device by sending SNMP requests every 2 minutes. The Corba based NMS fault management is fully push based and the NMS receives a notification when there is a fault. The size of the SNMP request and response PDUS is 150 bytes and the size of a CORBA notification is about 400 bytes. During 1 hour these are 20 alarms. Question: 1) Calculate the bandwidth used in both cases. 2) How do you differentiate between both the cases?
  • 3. CASE STUDY : 3 WLAN is created as an air interface 802.11 from 802.3 Ethernet interface. BSS comprises a set of wireless stations controlled by a wireless termination point (WTP) you have set up your home network using a wireless access point (WAP), which is connected to the Ethernet output of ADSL coming into your house. Question: 1) What are the two modes of MAC types that the WTP could be configured in? 2) Assume that you have a WIFI AP, how is it configured? 3) Write the SNMP query to use to validate your answer in (2) 4) What is your general understanding about the above.
  • 4. CASE STUDY : 4 As a network engineer in a Network Operations Center, you are following up on two trouble tickets. You do not have a network management system and you have to use the basic network tools to validate the problem before you can resolve them (i) Please explain what tools you would use in each case and how it would validate the consumer complaint? Question: 1) Trouble Ticket 100: Customer says that when he receives messages, the message is periodically missing some characters. 2) Trouble Ticket 101: Customer in Atlanta complaints that when she tried to lag into the system server, headquarters.com in New York, she gets disconnected with a time out. However, her colleague in her New York office reports that he is able to access the system.
