Question : An organization is considering installing a local area network (LAN) in a site under construction. If system availability is the main concern, which of the following topologies is MOST appropriate ?
The Correct Answer is : A. Ring Explanation : A ring or loop topology would enable messages to be re - routed should the network cabling be severed at any point or a hardware element failed. With the correct settings in network hardware, the loss of any link could be invisible to the users. In line and bus networks, which are essentially the same thing, terminals are connected to a single cable. If this cable is severed, all terminals beyond the point of severance will be unavailable. A star network clusters terminals around hubs, connected to the server by separate lines in the form of a star. If any line is severed, all terminals in the cluster at the end of that line would be disconnected.
