Fault Isolation

I’m about to leave for Nepal for a month and much of it without internet. So, this post and the next couple are homework for you. Take a look, work the problem, solve it, then show your work. Comment with why you chose your response and why you didn’t select one of the others.

This is question 17 from the ASQ CRE 2009 sample exam.

1. Fault isolation is best facilitated by using

(A) trouble reports, corrective action reports, and inspection data

(B) interchangeability, redundancy, and corrective maintenance

(C) preventive maintenance, built-in test equipment, and design simplification

(D) periodic condition inspections and correction of detected deterioration

Fault isolation can refer to many areas. The responses seem to focus on maintenance-type activities. Between the two how did you sort out a response?
