Which address type does a switch use to make selective forwarding decisions?
A.
Source IP address
B.
Destination IP address
C.
Source and destination IP address
D.
Source MAC address
E.
Destination MAC address
Explanation:
Switches analyze the destination MAC to make its forwarding decision since it is a layer 2 device.
Routers use the destination IP address to make forwarding decisions.
A media access control address (MAC address), also called physical address, is a unique identifier assigned to network interfaces for communications on the physical network segment. MAC addresses are used as a network address for most IEEE 802 network technologies, including Ethernet and WiFi. Logically, MAC addresses are used in the media access control protocol sublayer of the OSI reference model.
MAC addresses are most often assigned by the manufacturer of a network interface controller (NIC) and are stored in its hardware, such as the card’s read-only memory or some other firmware mechanism
