Q291.
Which among the following statements is false about the introduction of a cognitive radio in a wireless regional area network?

a.

Availability of spectrum access information to the secondary user

b.

Availability of spectrum access information to the primary user

c.

Knowledge of antenna height

d.

Usage pattern of wireless regional area network

Discuss
Answer: (b).Availability of spectrum access information to the primary user Explanation:The wireless regional area network comprises base stations, repeaters, and consumer premise equipment. It provides fixed wireless access services in rural areas. The inclusion of a radio environment map provides knowledge of location, antenna height, transmission power, and opportunistic spectrum access. It provides knowledge distribution and usage patterns of secondary users.
Q292.
Which among the following require radio transceiver database?

a.

RF environment awareness

b.

Location awareness

c.

Power consumption awareness

d.

Energy consumption awareness

Discuss
Answer: (a).RF environment awareness Explanation:RF awareness means to be aware of spectrum utilization, spectrum users, topology, interference, and other RF characteristics. Radio transceiver database, cooperative sharing, sensor networks, and field measurement are the methods applied to gain RF environment awareness.
Q293.
Which among the following techniques require geographic information database?

a.

Policy awareness

b.

Regulation awareness

c.

Mobility and trajectory awareness

d.

Background environment awareness

Discuss
Answer: (c).Mobility and trajectory awareness Explanation:Mobility and trajectory awareness computes the speed and direction of a cognitive radio. Speed and trajectory is estimated by analyzing the change of location of the radio over a period of time and by utilizing the resources of a geographic information database.
Q294.
Which among the following processes is required to extend radio adaption beyond predefined knowledge?

a.

Sorting

b.

Knowledge acquisition

c.

Reasoning

d.

Learning

Discuss
Answer: (d).Learning Explanation:The reasoning engine is responsible for applying the gathered knowledge in accordance with the current state of the system. However, the reactions will be limited to previously defined knowledge even under new situations. Learning provides the ability to study input, identify patterns, and modify the operation of the radio system as per the demands of the situations.
Q295.
Which among the following processes under learning action initiates a change in the action selection policy?

a.

Observation of state of the radio system

b.

Decision making in reasoning engine

c.

Analyses of the outcome of the decision selected by the reasoning engine

d.

Modification of knowledge base

Discuss
Answer: (d).Modification of knowledge base Explanation:The modification of the knowledge base step is generally the final step in a single learning cycle. The knowledge base is modified in accordance with the outcome of the actions implemented by the reasoning engine. The existing information in the knowledge base is altered, or the action selection policy is changed. Otherwise, new knowledge entries are included in the database.
Q296.
What is called declarative knowledge?

a.

Declarative knowledge represents a range of values applicable for assigning a variable

b.

Declarative knowledge represents assumed statements

c.

Declarative knowledge asserts and reasons over descriptive factual knowledge

d.

Declarative knowledge represents predicted knowledge

Discuss
Answer: (c).Declarative knowledge asserts and reasons over descriptive factual knowledge Explanation:Declarative knowledge involves asserting and reasoning over descriptive factual knowledge about an object. Declarative knowledge describes the semantic relationships between objects.
Q297.
Which among the following is concerned with the effect on a knowledge system?

a.

Behaviour knowledge

b.

Declarative knowledge

c.

Narrative knowledge

d.

Status and system knowledge

Discuss
Answer: (a).Behaviour knowledge Explanation:Behavioural knowledge involves actions and their effect on the knowledge system. Both internal and external effectors altering the system and the environment are included. An event begins with a set of assertions and terminates with a varying set of assertions.
Q298.
Which among the following is a benefit of symbolic knowledge representation?

a.

No encryption is required

b.

Fast translation

c.

Less memory storage

d.

Easy human comprehension

Discuss
Answer: (d).Easy human comprehension Explanation:Symbolic knowledge representation typically involves graphical or natural language notations. It is easy for humans to understand. It offers a simplistic means for conveying underlying information for human understanding and interpretation.
Q299.
Which among the following is not used for symbolic knowledge representation?

a.

Interface

b.

Objects

c.

Semantic nets

d.

Frames

Discuss
Answer: (a).Interface Explanation:In symbolic representation and reasoning systems, storage is performed using extensible data structures to capture facts, descriptions, and properties related to a concept. Semantic nets, rules, frames, and objects are some of the structures employed to represent knowledge.
Q300.
Which among the following is employed for associating new concepts in the learning process for ontology based systems?

a.

Dissimilarities between two consequent entries

b.

Similarities between two consequent entries

c.

Similarities to existing entries in memory

d.

Dissimilarities to existing entries in memory

Discuss
Answer: (c).Similarities to existing entries in memory Explanation:Learning in ontology based system involves integrating new knowledge with existing collection of entries in memory. A classifier is used to assess the degree of similarity between a new entry and the existing entries. The classifier accomplishes this by analyzing the properties and values of a new entry.
