Question 6 - Network Robustness

Regarding the robustness of complex networks, which of the following statements is false?

B. Scale-free networks with γ > 3 behave like random networks with respect to random failures

C. In comparison with random networks, scale-free networks have enhanced robustness

D. Hubs ensure robustness against random failures, but make networks vulnerable to attacks

E. None of the above

    Acho que aqui a intenção era que a resposta fosse (B), que não me parece verdadeira, mas temo questionamentos a respeito de (A), onde alguém pode argumentar que há suporte analítico e experimental, mas não há certeza. E vejo argumentação também sobre a (D), onde alguém pode dizer que não é só a presença de hubs, mas sim toda uma estruturação em torno de uma distribuição de graus livre de escala que provoca estes efeitos. Fico com medo de aceitá-la.
