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.
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
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.
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
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.
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.
