Q1 (a) FCAPS is an acronym used to describe the main functional areas of network management. Name and describe these functional areas and their management purpose. [10 marks] (b) The OSI network management model, divides the management responsibility into two roles, the Manager and Agent. Explain their respective positions in a management hierarchy and then show briefly how multi-layered management can be achieved with these roles. [10 marks]
(c) Name, compare and contrast the management approaches and technologies used with the ISO model and the Internet Engineering Task Force model. You should examine the relative features of the management models, the nature of the protocols used, the operations supported and the target applications for each model. [14 marks]
Q2 (a) The ISO and IETF both use the concept of an Object Identifier or OID to identify particular managed objects or pieces of information. Draw a diagram to explain how a managed object can be identified using an OID, how it exists relative to other OIDs and how this is written and named. [10 marks]
(b) The Simple Network Management Protocol V1 (SNMP_V1) uses a restricted set of messages types and operations. What are these five message types and can you explain how they can provide for basic configuration operations? [16 marks]
(c) SNMP uses well known port numbers for communication. What are these and what possible difficulties can occur when using on corporate networks with firewalls? [8 marks]
Q 4 (a) The following diagram, Figure 3, represents the data communication over a heterogeneous network consisting of elements from multiple vendors and using multiple forms of management technology with different protocols, to implement a mobile data session. Describe one modern technology standard and solution which would allow a coherent management view and structure. You should explain in your solution how a common object model is achieved and what technologies are employed. [20 marks]
(b) You should then separately describe how this data can be accessed and how protocol translation can occur within your selected framework. [14 marks]
