Q31.
Which among the following is not a part of the cognition subsystem?

a.

Inference hierarchy

b.

Cognition cycle

c.

Organisation

d.

Channel state

Discuss
Answer: (d).Channel state Explanation:The information services exhibit cognitive behaviour by using a set of design rules, functions, and components defined by the cognitive radio architecture that allow continuous growth through easy updates. The section of the cognitive architecture responsible for cognitive behaviour consists of inference hierarchy, cognition cycle, and temporal organisation.
Q32.
How does the cognition cycle operate?

a.

Active

b.

Reactive

c.

Passive

d.

Activated

Discuss
Answer: (b).Reactive Explanation:he cognition cycle carries out its functions in a reactive sequence. Stimuli from the outside world are accepted by the sensors. The information is passed to the cognition cycle to generate a response.
Q33.
Which among the following modes support real-time interaction?

a.

Waking

b.

Sleeping

c.

Prayer

d.

Prolong

Discuss
Answer: (a).Waking Explanation:The waking behaviour supports real time interaction with user and obtains real time input from the environment. It is also referred to as awake-state. However it does not imply a fixed state but a collection of behaviours.
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.
