  1. I would say B is the closest option to be “correct”, but it is not entirely correct. The switch would flood the frames out all the ports that belong to the Vlan where the broadcast was received. But not necessarily all ports, maybe only one port belongs to that vlan…

    Now, CAM table reaching the limit could cause that behavior. But not TCAM.

  2. B is correct.

    Frames are addressed to reach every computer on a given LAN segment if they are addressed to MAC address FF:FF:FF:FF:FF:FF.
