Answer:
a. Availability of software licensing
Explanation:
With feasibility analysis, we take into consideration economic, technical, legal, and scheduling factors to make sure that our project completes successfully. Acquiring license for a software can be free of cost or paid subscription. So a business analyst needs to make an account of the cost of accessing the software services. Also while automating a software installation process, it would require automatic authentication which would again require details of licensing. So in my best knowledge, analyzing availability of software licensing is a must and foremost step for a feasibility study.
Answer and Explanation:
Messages flow across an SDN controller's:
Northbound APIs:
• Messages which help in read/write state of the network and developing flow tables within the
state management layer.
• Notifications for the state-change events.
• The interaction between the controller and network control applications is done through the
northbound interface.
• Network control applications send messages to the controller.
Southbound APIs:
• Messages which help for the up-to-date view of the network's state like message for the
attached link has gone up or down, new devices are joined the network, or indications of the
device is up or down.
• Controller's southbound interface is the communication among the controller and the controlled
devices. Controlled devices are the recipients of the messages sent form the controller.

Explanation:
In case of a homogeneous network, Skype is an example and OpenTable is an example of a heterogeneous network.
<u>Homogeneous</u> networks are easier to get started with since its all pre-integrated, and even the troubleshooting is more convenient if a problem arises. However, it then becomes a security concern if you choose to place all that power to a single vendor - known as ' monoculture'. One event can affect the entire network. On the other hand, a <u>heterogeneous</u> set up does not run this risk. Several different components are utilized which are not as vulnerable to security threats.
In conclusion, homogeneous networks cost more and heterogeneous networks are more secure.
