The statement is pretty straightforward in asking you to briefly describe your experience with solenoids. If you have no experience in this area, be sure to be honest with your answer.
"I've worked on solenoids mainly to test whether they were working or not. The quickest way is to apply a charge directly to it. The multimeter sends a charge directly onto the valve, and if it opens, then I know it's working. I'm usually just testing them to see if the coil has burnt out, or if the valve has failed."
