Correct Answer: B. B. False
Explanation: Network administration is faced with two challenges: one is the increasing complexity of network equipment and the other the high attrition rate of technical staff. Hence, it is important for the NMS to have an easy-to-use user interface (UI). Increasingly, this is graphical (GU!) and may be browser based.

Correct Answer: A. A. True
Explanation: One of the important functions of the Performance Manager (PM) is data collection. This is done by periodically polling NEs for relevant performance data. The other important function of the PM is data analysis. Reports are generated to identify bottlenecks, analyze trends in order to plan capacity upgrades, and to tune the network and systems. Anomalies in performance trends may also indicate security problems such as denial of service attack.

Correct Answer: B. B. . the mdb contains the configuration information of each managed object. advertisement
Explanation: A number of modules are grouped around a central managed object database (MDB). The MDB contains the configuration information of each managed object.

Correct Answer: A. A. It receives notifications of events in network elements
Explanation: The Fault. Manager (FM) receives notifications of events in NEs. It may also infer faults by analysis of data. For instance, by comparing measured throughput. on a link with link capacity, it can detect a congestion fault. The FM notifies the operator through various means such as text, graphics, audio, etc. It may also take automatic corrective action to resolve a fault.

Correct Answer: B. B. False
Explanation: The topology of a network depends on the interconnections between routers and switches. Hubs are usually not SNMP-manageable and are not included in topology discovery.

Correct Answer: A. A. Cmip
Explanation: Functional modules communicate with the NEs through the protocol layer. This layer may support a number of common management protocols such as various versions of SNMP, XML, CMIP, and also proprietary protocols.

Correct Answer: B. B. Workstations
Explanation: The interfaces associated with various functions and services have been standardized in the TMN model. System operators interface with the operations systems using workstations.

Correct Answer: C. C. It is used to monitor the loss and signal-to-nosie ratio in the trunk transmission system in bell system
Explanation: The trunk test system is used to monitor the loss and signal-to-noise ratio in the trunk transmission system in Bell System. A trunk is a logical entity linking two switching offices.

Correct Answer: A. A. Osi
Explanation: TMN is necessary to extend the private and proprietary, but well-developed network management systems, and make them interoperable. It is to be kept in mind that TMN had been developed based on OSI management principles.

Correct Answer: B. B. False
Explanation: A logical entity, used to link two switching offices is known as Trunk. Each and every trunk in the network is inspected for their quality check. It is extremely necessary that a trunk qualifies the minimum criteria set for quality control otherwise they are removed from service.
