William has been working on a problem with a computer at his company for several hours and still can't ascertain the problem. The computer will not turn on, and William has tried everything he can think of to fix the computer. He has replaced the power cord, the power supply, and even the power strip the computer is plugged into. William decides that it must be the motherboard and takes the computer to his shop to replace the motherboard on the computer. When he plugs the computer in, it turns on. The problem was not the computer-someone had turned off the switch for the wall outlet that the power strip was plugged into. At which step in the troubleshooting process could William have discovered this problem? (Select all that apply.)
Identify the problem, Test the theory to determine cause, and Establish a theory of probably cause. He should have checked the wall socket.

Johan is a hard drive performance engineer working at a major storage device manufacturer. He needs to measure, record, and analyze the throughput, IOPS, and the latency of the different models of drives the company produces. What is the difference between these three parameters? Select three.
Latency measures the time required to process a data request or a transaction. IOPS measures the number of read or write operations performed in one second. Throughput is the amount of data flow through a point in the data path in one second.

George is involved with a project at work. Over the last few weeks, he has noticed a gradual but significant degradation in performance when running his AutoCAD program. He calls the technician and asks him to check his computer. The technician tells George to reboot the computer and asks George how much RAM was detected. The amount of RAM reported is exactly as expected. What hardware could be causing this problem? Select two.
Motherboard RAM
While working on your computer, you receive the POST error, "Drive Not Recognized." You check your SATA cable to see if it is the problem, and it tests fine. You remove the hard drive and test it in a computer system known to be in good working condition and find that the hard drive is working. You can move data and check to make sure the OS files are not corrupt. You use a power supply tester to see if the voltage for the SATA power connection is correct, and the test shows the power is correct. You even check BIOS to make sure the hard drive can be recognized and find that all settings in BIOS are at default, so the system should recognize the hard drive. What might be the problem with your hard drive system?
Motherboard SATA port has gone bad.
You are installing a new hard drive in a system in which the hard drive will run at 6.0 Gbps. What can you use to determine whether the SATA port number into which you are connecting the drive will also run at 6.0 Gbps? All ports are standard.
