Q1.
Which among the following tasks may be assigned software defined radio forum manager?

a.

Assessment of propagation link

b.

Assessment of input from user

c.

Administration of computational resources

d.

Administration of propagating signals

Discuss
Answer: (c).Administration of computational resources Explanation:The cognition functions supervise the computational resources available in a platform. Certain SDR functions such software defined radio forum manager may be assigned the task of management of resources. The appropriate constraints of a resource must be considered before allocation.
Q2.
What type of characteristic should be possessed by the topological model of the world created by the cognitive radio?

a.

Explicit and ambiguous

b.

Explicit and axiomatic

c.

Implicit and ambiguous

d.

Implicit and axiomatic

Discuss
Answer: (b).Explicit and axiomatic Explanation:The cognition functions define an explicit topological model of the world including the users, the radio environment, the connecting networks, and the internal structure of the radio. Time, space, frequency, and propagation of signal are clearly defined and the model is therefore axiomatic.
Q3.
Which among the following combination is responsible for the cognition cycle?

a.

Environment – cognition

b.

Effectors – SDR

c.

SDR – SDR

d.

Cognition – cognition

Discuss
Answer: (d).Cognition – cognition Explanation:The cognition-cognition combination helps in the following operations namely orienting, planning, decision-making, and creating actions which form the cognition cycle. The user may control the elements of the radio through cognition sub system.
Q4.
Which among the following functions control the environmental sensors?

a.

Cognition function

b.

Local effector function

c.

User SP function

d.

Perception function

Discuss
Answer: (a).Cognition function Explanation:The cognition functions control the environmental sensor. Data is sent from the cognition function to switch on/off the environmental sensors, constructing internal paths from the sensors and enabling control parameters.
Q5.
The allocation of computational resources must be in agreement with the requirements of user communication.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:The cognition functions sets up and administers the radio resources which includes hardware resources, software personalities, and function. The allocation of computational resources to applications, interfaces, and functions must be in agreement with the requirements of user communication.
Q6.
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.
Q7.
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.
Q8.
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.
Q9.
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.
Q10.
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.
