This set of Computer Network Management Multiple Choice Questions & Answers (MCQs) focuses on “Functional Model”.
1. _________ involves detection and isolation of the problem causing the failure in the network.
a) Configuration Management
b) Fault Management
c) Accounting Management
d) Security Management
View Answer
Explanation: Fault Management is a component of the Network Management Model. Apart from detecting and isolating problems in a telecommunication network, it also helps in the correction of those malfunctions.
2. _______ is an application oriented traffic that can be analyzed using performance-monitoring tools.
a) Web-traffic
b) File-transfer
c) Internet mail
d) Voice call
View Answer
Explanation: Performance-monitoring tools can gather statistics of all protocol layers. We can analyze the application-oriented traffic such as Web-traffic. The statistics on applications could be used to make policy decisions on managing the applications.
3. In Network Management __________ plays a vital role in secure communication between two networks.
a) monography
b) stenography
c) cryptography
d) sinography
View Answer
Explanation: Secured communication is concerned with the meddling of information as it traverses the network. The content of the information should neither be accessed nor altered by unauthorized third person. Cryptography plays a vital part in achieving this kind of security.
4. Relevant management information is embedded in managed objects, such as switches, hubs, bridges, and routers.
a) True
b) False
View Answer
Explanation: In Network Management Functional Model, the administration and maintenance of management information is looked after by configuration management. Thus each device in the network management system known as managed devices; possess some kind of management information. This setting up of parameters is involved in the configuration management.
5. Service and Business Management is an another dimension of application management, directed towards _________
a) device manager
b) customers
c) service providers
d) network manager
View Answer
Explanation: Service and Business Management is an another dimension of application management. It is directed towards service providers. These service providers ensure customer satisfaction and profitability of business.
6. __________ gathered by performance management serves as input to the process of accounting management.
a) Configuration Data
b) Security Data
c) Administration Data
d) Traffic Data
View Answer
Explanation: Accounting management looks after the cost allocation of the usage of the network whereas the performance behavior and the traffic of the network are managed by performance management. Traffic data gathered by performance management serves as input to this process.
7. In Fault management system, what can be used to track network problems?
a) Performance management tools
b) Trouble ticket administration
c) Metrics
d) Security database
View Answer
Explanation: Fault management involves the detection and isolation of the problem causing the failure in the network. A trouble ticket is generated and followed up for resolution of the problem using a trouble ticket administration system. Thus, a trouble ticket administration helps in tracking network problems.
8. Accounting management administers the traffic and performance statistics on the network.
a) True
b) False
View Answer
Explanation: There are five components of network management: Configuration Management, Fault Management, Performance Management, Security Management, and Accounting Management. Accounting management looks after the cost allocation of the usage of a network. The performance behavior and the traffic of the network are managed by performance management.
9. What is Self-healing in network management?
a) It involves physically securing the network
b) It is isolation of network problems
c) It is reconfiguration of network
d) It involves monitoring the traffic of network system
View Answer
Explanation: An NMS constantly monitors and displays in real-time major and minor alarms based on the severity of failures. Reconfiguration is a part of configuration management. In several failure situations, the network could do this automatically. This network feature is called self-healing.
10. The two primary ways of performing Fault Management are __________ and __________
a) guided, unguided
b) active, passive
c) wired, wireless
d) authorized, unauthorized
View Answer
Explanation: Active and passive are the two ways of performing the tasks of detection and isolation of problems in network. Passive fault management helps in collecting alarms from network devices whereas Active Fault Management monitors the health of these devices.
