Answer: A. In a mesh topology, all devices are connected directly to every other device on the network. If one link fails, there is always another available. It is the most fault-tolerant network topology. A hierarchical star is a variation of the standard star and is not considered a fault-tolerant implementation. A ring topology is not considered fault tolerant. In a star topology, each device is normally connected to one central device and therefore is not fault tolerant.
The best topology is ring topology. Star is the next best after ringr, and then bus, which is pretty old, but not too expensive. Full mesh topology is theoretically the best since every device is. connected to every other device, thus maximizing speed and security. These, however, are quite expensive to install. The next best would be. tree topology, which is basically a connection of stars.
