What type of connectors are specified to control noise and fan vibrations in metal ductwork for residential installations?

Flex connectors
S connectors and drive clips
Dampers and collars
Slip joints and cleats

The correct answer is: Flex connectors

Flex connectors are the most appropriate type of connectors to control noise and fan vibrations in metal ductwork for residential installations. Dampers and collars are typically used to control air flow, not noise and vibration. S connectors and drive clips are not as effective at reducing noise and vibrations, and slip joints and cleats provide minimal noise control and can potentially lead to air leaks.
