And please give a motivation to why the statements are correct (or not correct).

Here follows a mix of various statements about link layer protocols and equipment. Which of the statements are correct? Ethernet (IEEE 802.11) and WLAN (IEEE 802.11) both use the same MAC address format and the same MAC address space. Ethernet has gone from a shared bus topology to a star topology with an active switch in the middle. This was necessary in order to bring Ethernet to gigabit speed and beyond. Ethernet is for carrying Internet traffic. Hence, an Ethernet switch only knows how to switch IP datagrams. A switch that encounters a MAC destination address that it does not recognize, uses ARP to find out where the recipient is. An Ethernet switch forwards frames through broadcasting, so that each frame is sent on all ports
