Question
What is the function of a Layer 2 switch?A. Determines which interface is used to forward a frame based on the destinationMAC addressB. Forwards data based on logical addressingC. Duplicates the electrical signal of each frame to every portD. Learns the port assigned to a host by examining the destination MAC address
Solution
The function of a Layer 2 switch is:
A. Determines which interface is used to forward a frame based on the destination MAC address: This is true. A Layer 2 switch uses the MAC address of devices connected to it to decide where to forward the frames it receives.
B. Forwards data based on logical addressing: This is false. Layer 2 switches forward data based on physical (MAC) addresses, not logical addresses. Logical addressing is used by Layer 3 devices like routers.
C. Duplicates the electrical signal of each frame to every port: This is false. This is a function of a hub, not a switch. A switch only sends the frame out of the specific port that leads to the destination device.
D. Learns the port assigned to a host by examining the destination MAC address: This is true. Layer 2 switches learn the relationship between ports and connected devices' MAC addresses by examining incoming frames. This information is stored in a MAC address table.
