Discussion
Suppose the maintenance package identifies several possible field replaceable units (FRUs) that will resolve the problem. What should you do after turning the power off?
Answer: A
Correct answer: Replace the indicated parts, one at a time in the recommended order
Changing one part at a time is what identifies which was faulty; replacing them all at once repairs the machine but teaches nothing and wastes good parts. The recommended order puts the most likely first.
