Q51.
Which among the following is accomplished by the combination of cognition and effector functions?

a.

Control of user

b.

Control of cognition components

c.

Establish efferent path for control of effectors

d.

Establish efferent path for cognition components

Discuss
Answer: (c).Establish efferent path for control of effectors Explanation:The combination of cognition and effector functions is used to establish the efferent path for the control of effectors. The information services deliver the relevant data to effectors. The cognition function then arranges the data, develops a path, and oversees the flow of information.
Q52.
Which among the following methods may be used to estimate interference in cognitive radio?

a.

Model the radio

b.

Model the user behaviour

c.

Model the channel

d.

Model the propagation of signal

Discuss
Answer: (d).Model the propagation of signal Explanation:he cognition function replicate the propagation of radio signal with good quality to determine the level of interference expected towards other users of the spectrum. It may also be used to verify whether the interference level is within the specified limits imposed by the protocols pertaining to the location.
Q53.
What may be determined by modelling the domain of applications in cognitive radio?

a.

Determine parameters that support the application

b.

Determine the number of applications that run simultaneously

c.

Determine application that use same resources

d.

Determine the priority of applications

Discuss
Answer: (a).Determine parameters that support the application Explanation:The cognition functions model the domain of application to find out the parameters that offer the additional support needed for effectively running an application. Quality of service, data rate, and probability of link closure are examples of such parameters that influence wireless communication.
Q54.
When does a cognitive radio give up control of application?

a.

High traffic load

b.

Long period without input from user

c.

On receiving pre-emptive command from user

d.

Bad weather conditions

Discuss
Answer: (c).On receiving pre-emptive command from user Explanation:The cognition function transfers the control of applications, interfaces, and radio resources on receiving pre-emptive command from the network or from the user. The control may be transferred to a network or a primary user depending on defined protocols.
Q55.
What is the function of decide phase?

a.

Generation of alternatives

b.

Evaluation of alternatives

c.

Establishment of priority

d.

Selection among alternatives

Discuss
Answer: (d).Selection among alternatives Explanation:The decide phase selects from a number of options generated by the planning phase. It is responsible for allocating computational and radio resources to support software in accordance to the activated plan.
Q56.
Which among the following holds true for autonomous decision?

a.

Correlation between present condition and reference condition is high

b.

Correlation between present condition and reference condition is low

c.

Covariance between present condition and reference condition is positive

d.

Covariance between present condition and reference condition is negative

Discuss
Answer: (a).Correlation between present condition and reference condition is high Explanation:Autonomous decisions are taken when the correlation between present and reference condition is high. It is preferred when the radio has been operated previously in the same spatial-temporal context. Knowledge representation depends on the radio procedure components.
Q57.
What kind of decision relies on external confirmation?

a.

Tactical decision

b.

Independent decision

c.

Predictable decision

d.

Tentative decision

Discuss
Answer: (d).Tentative decision Explanation:Tentative decisions are consulted with the user for confirmation before execution. This leads to better user experience in the future. In certain situations, the selected option is executed and the user interaction is recorded to resolve conflict.
Q58.
The decision phase controls the timing of alerts in a radio.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:Other than selecting a particular option from a set of plans, the decision phase chooses the timing to alert a user. It might alert immediately or put off the interruption according to the circumstances of the user (such as until after a meeting).
Q59.
What function belongs to external oriented actions in act phase?

a.

Parse images and videos

b.

Compose messages for interaction with environment

c.

Parse incoming RF signals

d.

Parse texts

Discuss
Answer: (b).Compose messages for interaction with environment Explanation:The function of the act phase is to engage in contact with outside world by composing messages for interaction with the local environment. The message may also have to be transferred to another cognitive radio or to a cognitive node.
Q60.
Which among the following may be used to represent information that is continuously changing?

a.

Knowledge Manipulation Language

b.

Web Ontology Language

c.

RoXen Macro Language

d.

Radio eXtensibleMarkup Language

Discuss
Answer: (b).Web Ontology Language Explanation:Web Ontology Language is a family of knowledge representation languages for developing ontologies. Ontologies are similar in structure to class hierarchies in object-oriented programming. Ontologies are suitable for information that changes continuously such as the data found on the Internet.
