1 In order to protect the system from a hard-drive failure so that access to the data

is available immediately after the hard drive fails (with no delay), what two most

commonly used fault tolerance methods would you recommend? (Hint: suggest

two different RAID levels).

Assuming the workstation currently has one hard drive installed, what additional

hardware would be necessary to implement each of the two methods?

5.3 What additional fault tolerance method would you recommend in order to

protect the workstation from the other natural disasters like floods and fires?

Does this method protect against hard-drive failures as well? If so, why would

you not use it instead of (as opposed to in addition to) the methods discussed

above?

5.4 Develop a backup strategy for the workstation assuming that the amount of time

it takes to perform backups is not very important, but it is critical that restore

procedures take as little time as possible. Assume the company operates 7 days a

week and there should be a daily backup taking place. In the spaces below

specify the type of backup that should occur each day.
