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.
At the fault management level, network problems are found and corrected. Potential future problems are identified and steps are taken to prevent them from occurring or recurring. With fault management, the network stays operational, and downtime is minimized.he performance management level is involved with managing the overall performance of the network. Throughput is maximized, network bottleneck s are avoided, and potential problems are identified.
