Q11.
Which among the following describes the functions of cognitive radio?

a.

Define personalities

b.

Monitor knowledge

c.

Define antenna direction using pre-stored tables

d.

Support plug and play

Discuss
Answer: (b).Monitor knowledge Explanation:The cognition functions of a cognitive radio include monitoring and constructing knowledge, particularly of repeated actions and characteristics exhibited by user, surroundings, and radio. This helps information services to match the preferences of the user.
Q12.
What degree of capability is achieved by the installation of a GPS receiver in a radio?

a.

Aware

b.

Adaptive

c.

Cognitive

d.

Programmable

Discuss
Answer: (a).Aware Explanation:An aware device can obtain useful information. A device with GPS receiver is capable of sensing its location. However, a device becomes adaptive only when it uses the information for an application such as a map.
Q13.
How can a radio be trained to accept commands from one owner entity?

a.

Perception functions

b.

Sensory functions

c.

Awareness functions

d.

Adaptive functions

Discuss
Answer: (a).Perception functions Explanation:Perception functions can sense and trace known, unknown, and background information at all time. It is considered as a sub-category of cognition functions. The ability to accept commands from a particular entity and ignore all other entities is provided by perception functions.
Q14.
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.
Q15.
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.
Q16.
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.
Q17.
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.
Q18.
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.
Q19.
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.
Q20.
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.
