    THE KEY HERE IS "WITHOUT DAMAGING" THE SLAB. CORE CYLINDER TEST TAKES A CHUNK OUT OF THE POURED/CURED/EXISTING CONCRETE AND IT "DAMAGES" IT.

    WE DO THE SAME AT OUR FIRM, BUT FOR THIS TEST'S PURPOSE, GET FAMILIAR WITH DESTRUCTIVE VS NON-DESTRUCTIVE CONCRETE TESTING

    THE IMPACT HAMMER TEST IS A TINY DEVICE THAT DOESN'T EVEN SCRATCH THE SURFACE OF THE CONCRETE.

    Jorge is right, the rebound hammer is completely harmless. However, the question is awfully written, the correct answer must be Schmidt hammer, Swiss hammer or a Rebound hammer. An impact hammer is a totally different thing.

    This question is a CLASSIC  example of how you need to carefully read the question and hone in on the exact requirement.  The question clearly states "without damaging the floor."  You are correct that in the real world, sure, you could probably find an area of the floor that's out of view and take a cylinder.  To you and I, we'd walk in and not see this core having been taken out.  But - everyone above is correct - you've now damaged the floor.  Period.  The question doesn't give leeway to non-high profile areas.  Thus, it cannot be a correct answer in this instance.

    This is one of those black-and-white scenario questions that test your ability to grasp a concept and apply it directly. Try to avoid having your personal experiences trip you up here. 

    Hope this helps.
