Computer Networks — Test 6

Correct Answer: B. B. False
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).

Correct Answer: B. B. Extensible markup language
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.

Correct Answer: B. B. False
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.

Correct Answer: B. B. Security model, peer-to-peer model, centralized model, and decentralized model
Explanation: OSI network management model is governed by ISO standards. It is superior to most other models. The OSI network Management Model can be classified further into four models such as organization model, information model, communication model and functional model. Whereas tiered model, hierarchical model, client/server model, logical layered model, centralized model, decentralized model, physical model, security model and peer-to-peer model are types of architecture of TNM.

Correct Answer: C. C. Ietf
Explanation: IETF stands for Internet Engineering Task Force. It is a set of standards that implicitly defines the architecture for SNMP. SNMP network management is used for campus wide networks.

Correct Answer: B. B. False
Explanation: SNMP is used for managing Wide Area Networks (WAN) as well as Telecomm systems. Telecomm Management Network (TMN) on the other hand deals with Telecomm service providers only.

Correct Answer: A. A. The user-oriented requirements of network management
Explanation: The OSI network Management Model can be classified further into four models such as organization model, information model, communication model and functional model. The functional model deals with user-oriented requirements of Network management. Whereas Information model looks after the structure and organization of management information. The organization model deals with the components of a network management system and its functions. Lastly, the operation of layers in the application layer occurs in the communication model.

Correct Answer: C. C. It describes how the management information is structured
Explanation: The information model of the OSI network management deals with Structured Management Information (SMI) and information database known as Management Information Base (MIB). Here the SMI helps in defining the structure of management information.

Correct Answer: D. D. Functional
Explanation: The OSI network Management Model can be classified further into four models such as organization model, information model, communication model and functional model. Thus, in Web-based management, the applications developed falls under the functional model of OSI network management.

Correct Answer: B. B. False
Explanation: Configuration, fault, performance, security and accounting are the four functional areas of OSI network management. SNMP is the standard that manages WAN and telecomm systems.
