Question

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

I had been asked this question during an interview for a job.

Origin of the question is Building CRA on SDR Architecture in chapter Cognitive Radio Architecture of Cognitive Radio

Answer 1

Right answer is (d) Applicable for radio resources

The 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.
