Description
- Explain three (3) approaches that network administrators can use in order to ensure a fault tolerant network design without a single point of failure. Of the three (3) approaches discussed, determine the single approach that you would recommend for an enterprise network. Justify your choice.
Explanation & Answer
1. Mean Time to failure and Mean time to recover - Mean time to failure is the time until the device fails and mean time to recover is the time until the device recovers from failure that occurred. They are used to measure fault tolerance and avoidance.
2. Protecting the power supply - the system cannot work without power supply, that’s why its necessary to find a mechanism that will protect power problem.
3. Use of Disk arrays – the most common malfunction is probably hard disk. They are reliable but subject to failure. That why managers use disk arrays.
the most recommended is the protection of power supply since without power the system will not work.
