This set of Computer Network Management Multiple Choice Questions & Answers (MCQs) focuses on “NMS Design”.
1. In ______________ is controlled by a configuring file, which sets a number of parameters.
a) performance discovery
b) configuring discovery
c) discovery procedure
d) configuration management
View Answer
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.
2. Which of the following is one of the services provided by Telecom Network presently?
a) Remote Monitoring
b) Geographic Spread
c) Internet
d) Network Management
View Answer
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.
3. _____________ is a type of network that has a large number of manageable devices including switches, servers, routers, base stations, multiplexers, etc.
a) Scalability
b) Heterogeneity
c) Bursty Load
d) Geographic Spread
View Answer
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.
4. It is not important for the NMS to have an easy-to-use user interface.
a) True
b) False
View Answer
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.
5. Much of network management is performed remotely from the ____________
a) Mobile Station (MS)
b) Authentication Center (AUC)
c) Network Options Center (NOC)
d) Base Station (BS)
View Answer
Explanation: Much of network management Is performed remotely from the Network Operations Center (NOC). However, there are users who need to use the NMS from other locations. Subscribers may be located anywhere in the network.
6. One of the important functions of the Performance Manager (PM) is data collection.
a) True
b) False
View Answer
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.
7. The MDB contains the ___________ information of each managed object.
a) accounting
b) configuration
c) performance
d) security
View Answer
Explanation: A number of modules are grouped around a central managed object database (MDB). The MDB contains the configuration information of each managed object.
8. What is the function of a Fault Manager (FM)?
a) It receives notifications of events in Network Elements
b) It provides additional support for vendor specific MIB modules
c) It is responsible for automatically detecting the presence of new Network Elements in the network
d) It provides secure access to Network Elements
View Answer
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.
9. Hubs are usually manageable by SNMP and are included in topology discovery.
a) True
b) False
View Answer
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.
10. Functional modules communicate with the Network Elements through the _________
a) CMIP
b) SMTP
c) ICMP
d) ARP
View Answer
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.
