In general, inserting wires by hand a. may contaminate the wire b. is less likely to damage the wire c. can be easier and less time consuming than using an insertion tool d. is more likely to damage the wire 9. Grommet seal plugs are used a. to remove the grommets that surround the cavities b. to fill unused cavities c. for wireless communication d. for testing purposes 4

5 10. The rising water insertion sequence a. starts at the bottom and ends at the top b. starts at the top and ends on the bottom c. alternates between right to left and left to right movements d. starts in the middle and moves out in concentric circles 11. The sequence of inserting wires and verifying retention is commonly referred to as a. virtual continuity b. contact retention c. push/click/pull d. wire strain relief 12. Inadequate strain relief may result in a. unreliable connections b. contacts popping out of cavities c. tension on the grommets d. all of the above 13. The maximum insulation clearance for connector solder cups is a. no more than two wire diameters b. insulation touches the cup but does not interfere with solder wetting c. insulation enters the cup but doesn t touch the rear of the cup d. no more than one wire diameter 14. Keying is used to ensure a. a connector can be unlocked b. the insertion sequence is correct c. proper mating orientation d. electrical continuity 15.
