Correct Answer: B. B. Scalar
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.

Correct Answer: A. A. Physical, data link
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.

Correct Answer: C. C. Security architecture, physical architecture, and logical layered architecture
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.

Correct Answer: D. D. Handles administration, information and charges of service in a network
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.

Correct Answer: B. B. Association control service element (acse)
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.

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.
