2 Describe briefly SNMP operations?

Answer: SNMP: Simple Network Management Protocol (SNMP) is an "Internet-standard protocol for managing devices on IP networks". Devices that typically support SNMP include routers, switches, servers, workstations, printers, modem racks and more. SNMP is used mostly in network management systems to monitor network-attached devices for conditions that warrant administrative attention. SNMP is a component of the Internet Protocol Suite as defined by the Internet Engineering Task Force (IETF). It consists of a set of standards for network management, including an application layer protocol, a database schema, and a set of data objects.

3 Write a descriptive note on RMONv1.

Answer: The Remote Network MONitoring (RMON) MIB was developed by the IETF to support monitoring and protocol analysis of LANs.

4 Discuss the following Non-router based monitoring technique

A. Passive monitoring

Answer: Passive monitoring is a technique used to capture traffic from a network by generating a copy of that traffic, often from a span port or mirror port or via a network tap. This low risk implementation provides one of the highest values within Application Performance Management in terms of application visibility for the business. In general, this can be up and running providing details of the application performance in less than two days. It helps lay the foundation for performance trending and predictive analysis.

5 What are the tasks of a network monitor?

Answer: Network monitor: Network Monitor is a packet analyzer. It enables capturing, viewing, and analyzing network data and deciphering network protocols. It can be used to troubleshoot network problems and applications on the network. Microsoft Network Monitor 1.0 (codenamed Bloodhound) was originally designed and developed by Raymond Patch, a transport protocol and network adapter device driver engineer on the Microsoft LAN Manager Development team.

6 What are the main components of JMX SNMP manager? Explain each of them.
