A. Security
B. Configuration
C. Accounting
D. Performance
Explanation: SNPv1 provides active management tasks. It sets the foundation for performing fault and configuration management. In configuration management, network operations are controlled whereas in fault management network problems are solved.
A. Non-statistical
B. Dynamical
C. Statistical
D. Demographical
Explanation: The characterization of the performance of a computer network is statistical in nature. This led to the logical step of measuring the statistics of important parameters in the network from the NOC and the development of remote monitoring (RMON) specifications.
A. Passive
B. Active
C. Mobile
D. Dynamic
Explanation: SNMP messages going across the network between a manager and an agent is examined. This is accomplished by using a tool that “sniffs” every packet that is going across a local area network (LAN), opens it and analyzes it. Thus it is a passive operation.
A. True
B. False
C.
D.
Explanation: In RMON, individual segments can be monitored on a continuous basis. This characteristic of RMON proves to be more advantageous. It helps in faster detection and reporting of faults to the Network Management System. It provides better control of the network.
A. It is a device that deals with the storage of management information
B. It is a tool that addresses operation and administration of functional model
C. It is a device that does the function of monitoring the packets
D. It is a device that provides complete model for network management
Explanation: When SNMP messages going across the network between a manager and an agent is analyzed then it’s called network monitoring or probing. Here the messages are not modified. This is achieved using a device called network monitor or probe.
A. True
B. False
C.
D.
Explanation: Physical object and Processor are the two components of probe in a Network. When these two components operate from the same place, geographically then the probe is called as the local probe.
A. It is a processor that analyzes the data
B. It is remote monitoring of the network using a probe
C. It is a device that is connected to the transmission medium
D. It is a module that collects data from the remotely monitored networks
Explanation: Remote Monitoring Network can be defined as the standard that is used to gather information from a network for monitoring purpose. This gathering of information from a network can be accomplished using devices such as monitors, consoles, probes etc. Thus it is useful in remote monitoring of the network using a probe.
A. It reduces the necessity of agents in the network to be visible at all times to the nms
B. It provides additional support for vendor specific mib modules
C. It is an excellent medium for fault management
D. It is widely accepted and works good for device monitoring
Explanation: The use of RMON devices has several advantages. The overall benefits of implementing RMON technology in a network are higher network availability for users and greater productivity for administrators. One of the advantages of RMON is that it reduces the necessity of agents in the network to be visible at all times to the NMS. Other options convey the advantages of SNMP that are different from those of RMON.
A. True
B. False
C.
D.
Explanation: For a network configuration system to work successfully, several conditions need to be met. Network components are made by different vendors. Even the RMON devices may be from different vendors. Thus, just as in the communication of network management information, standards need to be established for common syntax and semantics for the use of RMON devices.
A. LAN
B. WAN
C. Pan
D. MAN
Explanation: A device that monitors the data packets in a network is called a network monitor or a probe. In a fiber-distributed data interface (FDDI) backbone network with a local Ethernet LAN. There are two remote LANs, one a token-ring LAN and another, an FDDl LAN, connected to the backbone network. Thus a token-ring probe monitors the token-ring LAN.
