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.
Best Practices. Use the 80/20 design rule Using more than one DHCP server on the same subnet provides increased fault tolerance for servicing DHCP clients located on the subnet. With two DHCP servers, if one server goes down, the other server can be made to take its place and continue to lease new addresses or renew existing clients.
