1. Assume that your company has 1,000 desktops, for which your CIO wants to deliver an operating system and environment on demand. Discuss which Microsoft desktop virtualization tools you would require and the corresponding cost.
2. An engine health monitoring system consists of a primary unit and a standby unit. The MTTF of the primary unit is 1000 operating hours, and the MTTF of the standby unit is 333 hr when in operation and 2000 hr while in standby status. Estimate the design life of the system if specifications require a reliability of 0.90. What is the system MTTF?
3. Two nickel-cadmium batteries provide electrical power to operate a satellite transceiver. batteries are operating in parallel, they have an individual failure rate of 0.1 per e the transceiver (at a reduced power output). How- ever, the increased electrical demand will triple the failure rate of the remaining battery 6.1 Determine the system reliability at 1, 2, 3,4, and 5 yr. What is the system MTTF?
