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, choiceB is more likely when the practice of stacking hubs and creating more terminal connections is used.
Yep, no image on this one either…

The question relates to the network topology needs to be revised to reflect the key word ‘risk’ in the q’s.
Anyway, close to the answer is:
\Ans A – multiple HUB means not only degrade the traffic but the most is ‘envites’ attack from adjacent network- ex. worms(virus) which propagates and contaminates other network.
\Ans B – high traffic due to many nodes/HUB would not address risk in the first place.
\Ans C – In terms of Systems Admin, managing the network would decloud the performance report of the network.
\Ans D – multiple HUB connectivity is likely vurnirable to internal hackers as well.
