  • 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.

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.

 examine two (2) strategies for tuning the network adapter of a Microsoft 2008 Server. Determine whether or not you would apply the same strategies to Windows Server 2012. Provide a rationale for your response

1.  Enabling offload feature-  This task is usually beneficial. However, it good to put in mind that the network adapter is not as powerful as it is required to handle offload capabilities. This strategy is applied only if the reduced through put is not expected to be a limitation.

2.  A strategy of enabling RSS (receive side scaling) – this strategy can improve web scalability and performance provided there are a fewer network adapters than the logical processors on the server. All the traffic goes through RSS-cable network adapters and incoming web requests can be processed across different CPUs simultaneously.

The same strategies can be applied with the windows server 2012 since it is just a development of Microsoft 2008 server.
