Q121.
Which among the following is considered as the most power-efficient device?

a.

ASIC

b.

FPGA

c.

DSP

d.

GPP

Discuss
Answer: (c).DSP Explanation:Digital signal processors are simple to program, cost-effective, and power-efficient when compared to other devices such as ASIC and FGPA. However small memory and complicated instruction set architecture can increase the re-programmability cost of a digital signal processor.
Q122.
How are the general purpose processors classified?

a.

Based on memory

b.

Based on bus

c.

Based on interface

d.

Based on instruction set

Discuss
Answer: (d).Based on instruction set Explanation:Complex Instruction Set Computer processor consists of a single instruction to carry out loading, evaluation, and storing operation. Reduced Instruction Set computer processor consists of a series of instructions to carry out loading, evaluation, and storing operation. The general purpose processors are commonly classified based on the instruction set.
Q123.
Which among the following is not an API of the software communication architecture put forth by the SDR forum?

a.

Physical

b.

MAC

c.

Security

d.

Transport

Discuss
Answer: (d).Transport Explanation:An application programming interface is a computing interface that connects to a software component or a system. Components may access the API as per the terms presented by the API itself. In software communication architecture, API determines access to the physical layer, to the logical link layer, to the medium access control layer, to the security features, and to the input/output components.
Q124.
Where does black processing occur in software communication architecture?

a.

Black processing occurs between antenna and RF channel

b.

Black processing occurs between antenna and RF conversion

c.

Black processing occurs between RF conversion and INFOSEC module

d.

Black processing occurs between antenna and INFOSEC module

Discuss
Answer: (d).Black processing occurs between antenna and INFOSEC module Explanation:Military radios assign the term ‘red’ for secret information. The term ‘black’ is used to refer to protected or encrypted information during transmission. Black processing generally takes place between the antenna and INFOSEC module, particularly the decryption process.
Q125.
Which among the following is given as input to the system control unit?

a.

Human-machine interface

b.

Global framework

c.

Fault management

d.

Configuration management

Discuss
Answer: (a).Human-machine interface Explanation:System control resembles a framework. It contains a set of basic functions that are arranged in the form of a computational architecture in accordance with the norms of CORBA. It accepts input from the human-machine interface unit and overlooks the management of virtual channels, networks, security, etc.
Q126.
Constraint programming consists of variables, constraints, and domains.

a.

True

b.

False

c.

May be True or False

d.

Can't say

Discuss
Answer: (a).True Explanation:In constraint programming, a problem is described as a mathematical equation. For example, ‘a’, ‘b’, ‘c’ are three whole numbers and the sum of ‘a’ and ‘b’ must be equal to ‘c’. Here ‘a’, ‘b’, and ‘c’ are the variables. The whole number corresponds to a domain. The sum of ‘a’ and ‘b’ must be equal to ‘c’ corresponds to a constraint.
Q127.
Which among the following is a challenge in security management?

a.

Authentication

b.

Validation

c.

Encryption and decryption

d.

Balancing convenience and security

Discuss
Answer: (d).Balancing convenience and security Explanation:Security management is controlled by the system control unit. It is responsible for protecting the user data using various safety measures such as encryption. Security management must carefully balance convenience and security. This can be a timing consuming process.
Q128.
Which among the following is not a common feature between virtual channel management and network management?

a.

Identification of resources

b.

Verification of availability of resources

c.

Matching resources with requirements of application

d.

Applicable for radio resources

Discuss
Answer: (d).Applicable for radio resources Explanation:Direct virtual channel management is responsible for identifying and verifying radio resources. It finds channels to transmit information, determines channels to listen for information, determines the channels that can be used simultaneously, etc. The network management performs the same operation on digital paths, not on radio resources.
Q129.
What is used by the cognitive radio to justify the usage of resources?

a.

Computational model

b.

Component cycle

c.

Function cycle

d.

Cognition model

Discuss
Answer: (a).Computational model Explanation:A computational model is used by the cognitive radio to keep track and to justify the usage of internal resources. The computational model consists of analog and digital parameters of performance. It also establishes the relationship between parameters on the basis of measurement and control.
Q130.
Which among the following is used to represent interdependencies in cognitive radio?

a.

Representation language

b.

Constraint language

c.

Ontology language

d.

Modelling language

Discuss
Answer: (b).Constraint language Explanation:The cognitive radio learns from the data structures of various phases of the cognition cycle and inference hierarchy to determine relationships among the information that would benefit the user. Constraint languages may be used to express the interdependencies found in the information. For example, constraint language may be used to express the number of channels supported by the radio hardware during failure mode.
