Correct Answer: C. C. Service providers
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.

Correct Answer: D. D. Traffic data
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.

Correct Answer: B. B. Trouble ticket administration
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.

Correct Answer: B. B. False
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.

Correct Answer: B. B. It is isolation of network problems
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.

Correct Answer: B. B. Active, passive
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.

Correct Answer: A. A. Trap
Explanation: It is very necessary to report problems occurring in a network to its respective network manager. Thus SNMP Trap messages are defined as alert messages that are sent to the network manager by the agent. This helps the network manager to take necessary actions on time.

Correct Answer: C. C. It is used to retrieve snmp object variables
Explanation: In Simple Network Management Protocol (SNMP) GET operations are used for retrieving SNMP object variables. GET, GETNEXT, GETBULK etc. are some of the SNMP message PDUs used for retrieving SNMP object variables.

Correct Answer: B. B. False
Explanation: SNMP is an asynchronous type of protocol. It means that messages are sent only when a problem is reported. This is a disadvantage.

Correct Answer: A. A. Lexicographic
Explanation: Lexicographic, Numerical, Collation and Alphabetical are conventional ways of arranging alphabets or objects in an order. Thus in SNMP we use Lexicographic convention for retrieval of objects.
