Question
1) 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.
2) Based on what you know about Unix so far, what would you tell someone wanting to learn more about Operating Systems.
How would you explain why you should use Unix vs another operating System. Or would you even recommend Unix?
Explanation / Answer
A network without any single point of failure contains
redundant network-infrastructure components (for example, switches and routers). Additionally, these redundant devices are interconnected with redundant links. Although a network host could have two network interface cards (NIC), each of which connects to a different switch, such a design is rarely
implemented because of the increased costs. Instead a network with no single points of failure in the backbone allows any single switch or router in the backbone to fail or any single link in the backbone to fail, while maintaining end-to-end network connectivity.
