Nms Design — Test 1

Correct Answer: B. B. Configuring discovery
Explanation: The strategy used in the discovery process is to check a range of IP addresses for the presence of Network Elements using the simplest and most generic possible techniques. Thus Configuring Discovery is a discovery process. Here the discovery is controlled by a configuring file, which sets a number of parameters.

Correct Answer: C. C. Internet
Explanation: The characteristics of telecom or large enterprise network helps in providing a variety of services. Telecom networks today provide a variety of: services including voice, data, Internet, and video.

Correct Answer: A. A. Scalability
Explanation: Scalability is important to the life network administrator. Typically, such a network has a large number of manageable devices including switches, servers, routers, base stations, multiplexers, etc.

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.
