Answer 8: Repository parameters enable you to specify that certain property values should be parameterized, but leave the actual parameterization to be defined in each test that is associated with the object repository that contains the parameterized test object property values.

Repository parameters are useful when you want to create and run tests on an object that changes dynamically.

Repositories collection is a collection object that enables you to programmatically manage the run-time collection of shared object repository files associated with the current action, for more details check QTP Help file.
