Identify the differences in the two MIBs that exemplify this difference. 3. Explain the GetRequest-PDU and GetNextRequest-PDU SNMP operations in detail. 4. a) Discuss in detail about SNMPv2 structure of management information. b) Briefly explain about SNMPv2 protocol data structures and its operations. 5. a) Explain the RMON1 groups and their functions. b) Explain the relationship between control and data tables. 6. a) Explain the TMN information architecture. b) Explain the TMN architecture realization by means of an example. 7. a) Explain briefly about the protocol analyzer. b) Explain the network status monitoring commands that are available in the UNIX and Windows environments. 8. a) Write about the DMI infrastructure. b) Explain the JMX architecture.

3 Set No a) Explain the basic communication architecture. b) What are the goals of network management? c) What are the challenges in managing the network? 2. a) Describe in detail about organization and information models. b) An SNMP manager sends a request for the values of the sys Uptime in the System group and if Type in the interfaces group for if Number value of 3. Write the PDUs with the fields filled in for i) the get-request PDU ii) the get-response PDU with nosuchname error message for iftype. 3. a) Explain the functional model of SNMP. b) Explain the GetRequest-PDU SNMP operation in detail. 4. a) Explain the SNMPv2 network management architecture on multiple transport domains. b) Explain the GetBulkRequest-PDU operation in SNMPv2. 5. a) Explain in detail about RMON groups and functions.also give relationships between control and data types. b) Describe in detail about ATM remote monitoring. 6. a) Explain the TMN functional architecture. b) Explain the various issues in implementing TMN. 7. a) Explain about the functional components of a NMS. b) Write short notes on Tivoli enterprise manager. 8. a) Explain the architecture of web based enterprise management. b) Write the desktop management interface (DMI) functional block diagram.

4 Set No a) Compare SNA, OSI and Internet protocol layer models. b) Explain various groups of network management functions. 2. a) Write the object DESCRIPTOR and syntax of the following SNMP managed entities i) IP address ii) a row in the interfaces table ( the row specifications only, not the objects in the row) iii) the MAC address of an interface card. b) Explain in detail about SNMP protocol specifications and SNMP operations. 3. Explain in detail the administrative model of SNMP. 4. a) Explain the changes to the system group in SNMPv2. b) Generate an ASN.1 OBJECT_GROUP macro for the address translation group in SNMPv2 implementation. 5. a)how would you measure the types and distribution of frames in a token ring LAN. b) An NMS connected to the Ethernet LAN is monitoring a network of 10,000 nodes comprising routers,hubs and workstations. It sends an SNMP query to each station once a minute and receives a response when the stations are up. Assume that an average frame size is 1000 bytes long for getrequest and response messages. i) What is the traffic load on the LAN that has the NMS? ii) If the Ethernet LAN operates at a maximum efficiency of 40% throughput, what is the overhead due to network monitoring. 1 of 2
