Q61.
Which among the following is not a challenge imposed by decision making in cognitive radio?

a.

Centralization

b.

Distribution

c.

Algorithms

d.

Wrong choices

Discuss
Answer: (d).Wrong choices Explanation:The first challenge for decision making is where and how the decision should be taken. The second challenge is whether the implementation must be centralized or distributed. The third challenge is the selection of decision algorithm.
Q62.
The concrete ____ of learning process is a challenge imposed by learning in cognitive radio.

a.

definition

b.

classification

c.

categorization

d.

manipulation

Discuss
Answer: (a).definition Explanation:The concrete definition of learning process, its objectives and contributions, is a challenge imposed by learning in cognitive radio. The learning mechanisms employed may be supervised or unsupervised.
Q63.
In dynamic security implementation, there is an increase in the number of potential interaction that can lead to a violation.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:In dynamic security implementation, there is an increase in the number of potential interaction that can lead to a violation. This leads to a decrease in time and special scales of these interactions. These conditions amplify the challenges.
Q64.
____ are used to interact with the environment.

a.

Sensors

b.

Actuators

c.

Structure models

d.

Memory

Discuss
Answer: (b).Actuators Explanation:A cognitive radio consists of sensors to collect information on the environment, actuators to interact with the environment, and a model of the environment with observed events stored in memory.
Q65.
Cognitive radio requires ____ to lower the impact in case of malfunction.

a.

diodes

b.

regulators

c.

PID controllers

d.

bridges

Discuss
Answer: (b).regulators Explanation:Cognitive radio requiresregulators to lower the impact in case of malfunction. The most popular regulator used to constraint a cognitive radio is a regulatory policy engine that has machine-readable and interpretable policies.
Q66.
The ____ property allows elimination of a policy upon producing undesirable results.

a.

evaluate

b.

examine

c.

try out

d.

permanent

Discuss
Answer: (c).try out Explanation:Machine readable policy controlled radio allows a policy to be implemented on few radios to assess the impact of the policy. If the results are undesirable, then policy can simply be eliminated. This enables quick decision making.
Q67.
_________ regulations can be made in policy driven approach.

a.

Material variant

b.

Size variant

c.

Temperature variant

d.

Spatially variant

Discuss
Answer: (d).Spatially variant Explanation:Policy driven approach allows temporal and spatially variant regulation. For example, a radio can automatically adapt to varying jurisdictions imposed by different countries by modifying or uploading a policy.
Q68.
Which among the following allows quality of service measurement?

a.

Software capable radio

b.

Software programmable radio

c.

Software defined radio

d.

Aware radio

Discuss
Answer: (d).Aware radio Explanation:An aware radio provides quality of service measurement and channel state information in addition to the services provided by software defined radio. However it cannot modify the radio parameters according to sensor input.
Q69.
Which among the following is a quality not available in a software capable radio?

a.

Frequency hopping

b.

Networking capability

c.

Link establishment

d.

Programmable cryptography

Discuss
Answer: (b).Networking capability Explanation:Frequency hopping, link establishment, and programmable cryptography are the features available in software capable radio. Each higher level radio possesses these basic capabilities with additional qualities. Networking capability and multi-waveform interoperability are additional features exhibited by software programmable radio.
Q70.
Cognitive radio includes ____

a.

heterogeneous infrastructure

b.

asymmetrical infrastructure

c.

equivalence infrastructure

d.

symmetrical infrastructure

Discuss
Answer: (a).heterogeneous infrastructure Explanation:Heterogeneous network have heterogeneous radio framework management. It is possible to allocate frequency bands to different radio access technologies. Thus combination of different technologies can be achieved by heterogeneous network.
