Introducing inhomogeneity to your network for the sake of robustness would have which of the
following drawbacks?

A.
poorer performance.

B.
poor scalability.

C.
weak infrastructure.

D.
high costs in terms of training and maintenance.

E.
None of the choices.

Explanation:
An oft-cited cause of vulnerability of networks is homogeneity or software monoculture. In particular,
Microsoft Windows has such a large share of the market that concentrating on it will enable a
cracker to subvert a large number of systems. Introducing inhomogeneity purely for the sake of
robustness would however bring high costs in terms of training and maintenance.
