Q21.
In ____, interoperability is achieved by using ____ waveform.

a.

cognitive-cognitive radio, same

b.

cognitive-legacy radio, different

c.

cognitive-cognitive radio, different

d.

legacy-legacy radio, different

Discuss
Answer: (a).cognitive-cognitive radio, same Explanation:There are two arrangements namely cognitive-cognitive radio and cognitive-legacy radio. Communication maybe carried out if both cognitive radios use the same waveform. Otherwise a waveform is chosen by both radios prior to communication.
Q22.
Which among the following is done to establish communication?

a.

Legacy radio reconfigures for communication

b.

Cognitive radio uses different waveform for communication

c.

Cognitive radio adapts legacy radio waveform

d.

Legacy radio adapts cognitive radio waveform

Discuss
Answer: (c).Cognitive radio adapts legacy radio waveform Explanation:Communication between cognitive and legacy radio may be achieved only if the former uses the waveform supported by legacy radio. Legacy radio does not have re-configurability features.
Q23.
Tracking the position of cognitive radio without ____

a.

authorization violates user privacy

b.

authorization is an adversarial attack

c.

authentication violates user privacy

d.

authentication is an adversarial attack

Discuss
Answer: (a).authorization violates user privacy Explanation:Security and privacy are major points of concern in a cognitive radio. The two main threats are tracking the position of cognitive radio without authorization and adversarial attack. The former is a threat to user privacy and the latter can lead to malfunction of several location based application.
Q24.
Geopriv is a working group under the ____

a.

International Engineering Task Force

b.

International Education Task Force

c.

Internet Engineering Task Force

d.

Internet Education Task Force

Discuss
Answer: (c).Internet Engineering Task Force Explanation:Geopriv is working group under IETF mainly involved in wired networks. It examines the authorization, privacy, security, and integrity required for a particular transfer of information.
Q25.
Which among the following is not a location based service?

a.

Package tracking

b.

Road side assistance

c.

Patient tracking

d.

Handover

Discuss
Answer: (d).Handover Explanation:Location awareness applications are mainly classified into location based services, location assisted transceiver optimization, location assisted network optimization, and location assisted environment identification. Package tracking, road side assistance, and patient tracking are location based services. Handover falls under location assisted network optimization.
Q26.
Which among the following is not feature of environment awareness core?

a.

Propagation channel characteristics

b.

Topographical information

c.

Meteorological information

d.

Security

Discuss
Answer: (d).Security Explanation:Environment awareness engine consists of environment sensing, environment awareness core, and environment adaption. The type of information required, means to acquire the information, and utilization of collected information are concerns of environment awareness engine.
Q27.
____ is the practice describing the arrangement of a particular place.

a.

Topology

b.

Topography

c.

Digital elevation model

d.

Time mapping

Discuss
Answer: (b).Topography Explanation:Topography describes the shapes and features of land surface. It provides accurate and detailed description of a place, city, town, or any tract of land. It includes vegetation and human made structures.
Q28.
Which among the following is not an example of topographical application?

a.

Geoscience

b.

Topographic maps

c.

Nano-topography

d.

Networking

Discuss
Answer: (d).Networking Explanation:One of the main applications of topography is topographic maps. There are applications being developed where a captured image is used as input to gather information on the location and environment. This is feature of interest for location and environmental awareness in cognitive radio.
Q29.

a.

Geology

b.

Geography

c.

Geoscience

d.

Geomorphometry

Discuss
Answer: (d).Geomorphometry Explanation:Geomorphometry involves describing the terrain, the three dimensional quality of the surface, and the identification of landmarks. It uses mathematical, statistical, and image processing techniques to describe the land surface.
