Q31.
Why is the RXML statement <Self/> added in cognitive radio?

a.

To add cognitive architecture to cognitive radio

b.

To define functions

c.

To define interfaces

d.

To eliminate components

Discuss
Answer: (a).To add cognitive architecture to cognitive radio Explanation:The cognitive radio must evaluate, monitor, and access all resources including affirming downloads. The statement <Self/> is a self-referential component. It is used to add the aware, adaptive, and cognitive radio architecture to aware, adaptive and cognitive radio.
Q32.
What capability demand was boosted upon introduction of machine learning in cognitive radio?

a.

RF sensing

b.

Haptic sensing

c.

Knowledge acquisition

d.

Resource acquisition

Discuss
Answer: (c).Knowledge acquisition Explanation:Availability of knowledge of a certain degree is essential in cognitive radio to extract user knowledge pertaining to information services. The repeated occurrences of similar activity are considered as learning opportunities. This is exploited by machine learning for incremental knowledge acquisition.
Q33.
Which among the following methods enable identification of learning opportunities in machine learning in cognitive radio?

a.

Gamma distribution

b.

Joint probability statistics

c.

Variance

d.

Uniform distribution

Discuss
Answer: (b).Joint probability statistics Explanation:Machine learning uses joint probability statistics for exploiting learning opportunities that arise due to repeated occurrence of similar situation. High quality use cases help to locate classes of user and knowledge that fine tune the set of services being provided.
Q34.
Which ontologies must work together for seamless user interaction experience?

a.

<User/> and <Self/>

b.

<User/> and <RF/>

c.

<Self/> and <User/>

d.

<Self/> and <Func/>

Discuss
Answer: (b).<User/> and <RF/> Explanation:The best user interaction experience is built when the radio can understand vague commands from the owner. This requires continuous development of user ontology. It also requires the matching of user ontology with RF domain actions.
Q35.
What does grounding mean in terms of ontology comprehension in cognitive radio architecture?

a.

Association of language used by user with that of cognitive radio

b.

Association of language used by cognitive radio with that of user

c.

Association of network used by user with that of cognitive radio

d.

Association of network used by cognitive radio with that of user

Discuss
Answer: (b).Association of language used by cognitive radio with that of user Explanation:Grounding initially beings with installation of a speech recognition subsystem that identifies common phrases used by the owner while referring to particular services. It is accomplished by text and speech recognition. It also involves asking “yes or no” questions either verbally or on display.
Q36.
Which among the following is added to AACR architecture to construct dialogs?

a.

NL acoustic facility

b.

NL visual facility

c.

Synonyms

d.

Distributive inference hierarchy

Discuss
Answer: (c).Synonyms Explanation:The RF concepts are presented to non-technical users by carefully constructing dialogs between <RF/> and <User/>. The introduction of synonyms in AACR architecture coordinates cognition–NL–synthesis interface. For example, the term antenna is associated with wireless-remote speaker.
Q37.
<User/> learns jargon to express connectivity opportunities to cognitive radio.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (b).False Explanation:<RF/> learns jargon to express connectivity opportunities to cognitive radio in <User/> terms. The NL visual facility is employed for improving user jargon one instance at a time.
Q38.
Which among the following support video-acoustic combination of interfaces in cognitive radio?

a.

Full-media correlation interfaces

b.

Full-media difference interfaces

c.

Cross-media correlation interfaces

d.

Cross-media difference interfaces

Discuss
Answer: (c).Cross-media correlation interfaces Explanation:The functional components operate together for effective operation of cognitive radio. The functional component “User SP” combines with itself for reducing operations provoked by irrelevant triggering actions. For example, video-acoustic combination help in eliminating voice commands when the person is not talking on video.
Q39.
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.
Q40.
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.
