This set of Computer Network Multiple Choice Questions & Answers (MCQs) focuses on “Network Management Standards”.
1. ____________ is a network management protocol that is specified in the OSI Model.
a) Component Management Internet Protocol
b) Common Management Information Protocol
c) Simple Network Management Protocol
d) Signal Network Management Protocol
View Answer
Explanation: Common Management Information Protocol (CMIP) is a standard that was introduced as a substitute for Simple Network Management Protocol (SNMP). CMIP is used along with Common Management Information Services (CMIS) as an OSI Standard protocol. Thus it is specified in the OSI Model.
2. Which one of these is a Management notification service made available by Common Management Information Service Element (CMISE)?
a) M-ACTION
b) M-DELETE
c) M-EVENT-REPORT
d) M-CANCEL-GET
View Answer
Explanation: There are a number of services made available by Common Management Information Service Element (CMISE). M-EVENT REPORT is a management notification service. It is used for sending notifications of managed object events to the user. Services like M-ACTION, M-DELETE, and M-CANCEL-GET are management operation services that are used to send information about system operations to users.
3. The managed objects are defined as ___________ objects in SNMP.
a) tensor
b) scalar
c) vector
d) spinor
View Answer
Explanation: In SNMP, there are two types of managed objects: Scalar objects and Tabular Objects. In SNMP, major operations are applied to scalar objects. The major difference between scalar and tabular object is that the former has one instance and the latter has multiple instances.
4. The IEEE standards for Local Area Network (LAN) and Metropolitan Area Network (MAN) specifications are concerned with OSI layers __________ and _________
a) Physical, Data Link
b) Network, Transport
c) Session, Presentation
d) Data Link, Network
View Answer
Explanation: There are a set of IEEE standards that are used for network management. IEEE 802 standards are defined in Physical and Data Link Layers of OSI Model. It defines protocols, services etc. for Local Area Network (LAN), Metropolitan Area Network (MAN) and other Wireless Networks.
5. The three architectures of TMN are ____________
a) Centralized architecture, Decentralized architecture, and Hierarchical architecture
b) Tiered architecture, Peer-to-peer architecture, and Client/Server architecture
c) Security architecture, Physical architecture, and Logical Layered architecture
d) Peer-to-peer architecture, Security architecture, and Centralized architecture.
View Answer
Explanation: TMN architecture can be divided into three perspectives and those are Security architecture, Physical architecture, and Logical Layered architecture. Network management architecture consists of a Network Management system (NMS), Network Management protocol, Managed devices, Management agents and Management Information. Tiered architecture, Peer-to-peer architecture, and Client/Server architecture are the three types of Network architecture. Centralized architecture, Decentralized architecture, and Hierarchical architecture are architectures of Database Management System.
6. There are four logical layers of TMN wherein the Service Management Layer ____________
a) analyzes business aspects, trends and billing options
b) performs configuration, control, and distributes network resources
c) handles network elements, network information and helps in maintenance
d) handles administration, information and charges of service in a network
View Answer
Explanation: TMN has four logical layers that are based on the network management services: business, network, service, and element. These layers are Business Management, Network Management, Service Management, and Element Management. Thus, Service Management Layer looks after services in a network and its administration.
7. __________ is used to establish association between two network entities.
a) SMTP (Simple Mail Transfer Protocol)
b) Association Control Service Element (ACSE)
c) Remote Operation Service Element (ROSE)
d) ICMP (Internet Control Message Protocol)
View Answer
Explanation: Association Control Service Element (ACSE) is used for establishing as well as releasing associations between two network entities. Whereas Remote Operation Service Element (ROSE) is used for remote operations and helps in interaction between network entities in a distributed system. SMTP is a set of standards that allows transmission of electronic mail over internet. ICMP, on the other hand, is a protocol standard used for notifying error messages to the network devices.
8. Telecomm Network Management is a protocol model that is adopted by ANSI.
a) True
b) False
View Answer
Explanation: Telecomm Network Management Standards are defined by the International Telecommunication Unit (ITU-T). Whereas IEEE standards were adopted by the American National Standards Institute (ANSI).
9. XML based network management uses _____________ technology for network management.
a) Cascading Style Sheets
b) Extensible Markup Language
c) JavaScript Object Notation
d) Hypertext Markup Language
View Answer
Explanation: Extensible Markup Language (XML) Technologies are used in XML based network management. It is used along with SNMP in order to resolve management of network elements in an ad- hoc manner. It resolves the problem of configuration management faced in SNMP. Whereas Cascading style Sheet (CSS) is a language used for styling web pages. JavaScript Notation (JSON), on the other hand, is somewhat similar to XML and is used for serializing data. Hypertext Markup Language (HTML) is used for building web applications.
10. CMIP and SNMP protocols use IEEE standards for the upper layers.
a) True
b) False
View Answer
Explanation: CMIP standards are specified in the OSI Model and SNMP is specified in the Internet Model. The IEEE specifications define the standards for the various physical media and data link protocols. Therefore CMIP and SNMP protocols use IEEE standards for the lower layers of the OSI Model.
