Smart people needed which of the following situations can directly lead to failure of a network based on start topology? the main wire that acts as the backbone is old, and the protective cover is fraying. the system acting as the hub soda spilled on it there are a couple of computers in the network that have trouble maintaining a signal one of the computers on the system has a lot of malwarre installed on it

D doesn't make much sense, it's valid, but not what we're looking for. B also has a correlation with D, same reasoning applies. As for A, it seems pretty legit, but I don't believe that's what we're looking for.

Choice C is the most obvious one though. We're talking about a network and as may or may not know it's a wireless one in a manner of speaking. A couple of computers in the network that have trouble maintaining a signal will indefinitely lead to failure of a network since both the links and nodes of certain computer systems are incapable of maintaining a signal.
