All the statements provided are true differences between Activity on Node (AON) and Activity on Arrow (AOA) networks. AOA networks do indeed sometimes require dummy activities to accurately represent the project's logical relationships. In AOA networks, nodes (which represent events or milestones) consume no resources or time, whereas in AON networks, the nodes represent the activities themselves, which do consume resources and time. Both types of networks are used in practice, but tools like Microsoft Project typically use the AON approach. Lastly, the fundamental difference in how activities are represented (nodes in AON vs. arrows in AOA) is correctly stated.
