In the 2c area of the diagram, there are three hubs connected to each other. What potential risk might this indicate?

A. Virus attack

B. Performance degradation

C. Poor management controls

D. Vulnerability to external hackers

Explanation:

Hubs are internal devices that usually have no direct external connectivity, and thus are not prone to hackers. There are no known viruses that are specific to hub attacks. While this situation may be an indicator of poor management controls, choice B is more likely when the practice of stacking hubs and creating more terminal connections is used.
