Which among the following is not a function of the MAC layer in cognit

1.	Which among the following is not a function of the MAC layer in cognitive radio?(a) Manage accessibility of assets(b) Change client configuration(c) Change density of design(d) Choose multiple access techniquesThis question was posed to me in a job interview.I would like to ask this question from Next Generation Wireless Network topic in chapter Next Generation Wireless Network of Cognitive Radio
Answer» Correct option is (d) Choose MULTIPLE ACCESS techniques Easiest explanation: MAC layer in cognitive radio should manage the level of accessibility provided for resources of the radio. MAC layer should be AWARE of channel occupancy and surrounding spectrum environment to quickly HANDLE changes in the environment and to mitigate loss PRODUCED due to mobility. MAC layer should have the capability to change design configuration.
