Q31.
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.
Q32.
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.
Q33.
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.
Q34.
What type of control is exhibited by awake-state of cognition subsystem?

a.

Temporally different

b.

Isochronous

c.

Asynchronous

d.

Serial

Discuss
Answer: (b).Isochronous Explanation:The awake-state or waking behaviour controls the cognitive radio resources isochronously. It maps the stored environmental interactions to the present input-response case being operated. Machine learning converts these interactions and cases into knowledge.
Q35.
Which among the following modes should be invoked when a considerable period of disuse is expected?

a.

Off

b.

Prayer

c.

Sleeping

d.

On

Discuss
Answer: (c).Sleeping Explanation:When long periods of disuse are predicted, the cognitive radio should enter into sleeping behaviour by itself. The cognitive radio is trained to identify situations that require sleeping behaviour. It may seek permission before entering sleep mode.
Q36.
What type of operations is performed in sleeping behaviour?

a.

No operation

b.

Non incremental machine learning

c.

Incremental machine learning

d.

Current knowledge generation

Discuss
Answer: (b).Non incremental machine learning Explanation:During sleeping behaviour, the radio processes the experience accumulated during the waking behaviour. This is accomplished by using non-incremental machine learning algorithms. It will map the present case integrated knowledge to overall integrated knowledge.
Q37.
What is the responsibility of prayer behaviour?

a.

Invoke sleeping behaviour

b.

Invoke waking behaviour

c.

Resolve conflicts

d.

Erase present input-response behaviour

Discuss
Answer: (c).Resolve conflicts Explanation:When the user chooses to disregard the decision taken by the cognitive radio, it is added to a list of conflicts. These conflicts may be resolved using overall knowledge developed during sleeping behaviour. Otherwise it is added to a list of unresolved conflicts which is resolved during praying behaviour.
Q38.
What language is used by prayer behaviour to work with the home network while resolving a conflict?

a.

Web Ontology Language

b.

Radio Knowledge Representation Language

c.

RoXen Macro Language

d.

Knowledge Query and Manipulation Language

Discuss
Answer: (d).Knowledge Query and Manipulation Language Explanation:Prayer behaviour resolves conflict with the help of home network. The conflict is presented to the network using Knowledge Query and Manipulation Language. If the conflict is resolved, it is integrated into overall knowledge.
Q39.
The entrance of a stimulus invokes a new cognition cycle.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:The entrance of a stimulus invokes a new cognition cycle during the waking behaviour. It is also invoked by the completion of cognition cycle which was already in process. The stimulus is obtained by monitoring the information signals such as voices, images, radio signals, etc.
Q40.
What is the function of the observe phase?

a.

Sense and perceive

b.

Sense and respond

c.

Perceive and respond

d.

Sense and forget

Discuss
Answer: (a).Sense and perceive Explanation:The observe phase interacts with the environment by analysing the input information stream. It may accept multiple inputs from different directions and in different format.
