A. B. C. D.AD
Layer 2 broadcast frames are used for broadcasting information to all devices within a specific network segment. They are identified by a destination MAC address of ff:ff:ff:ff:ff:ff. Here are the correct statements about Layer 2 broadcast frames:
A. Layer 2 broadcast frames are processed by all devices on the same VLAN. This statement is correct. When a Layer 2 broadcast frame is sent out by a device within a VLAN, all other devices within that VLAN will receive and process the frame. This includes switches, routers, and other devices.
B. Layer 2 broadcast frames are discarded by routers that connect to multiple VLANs. This statement is also correct. Routers are designed to connect multiple networks together and typically do not forward Layer 2 broadcast frames between networks. Instead, they rely on Layer 3 broadcast mechanisms such as ICMP to propagate information between networks.
C. Layer 2 broadcast frames are relayed by routers to all connected VLANs. This statement is not correct. As mentioned earlier, routers typically do not forward Layer 2 broadcast frames between networks. They instead rely on Layer 3 broadcast mechanisms to propagate information.
D. Layer 2 broadcast frames are relayed by switches to devices on the same VLAN. This statement is also correct. Switches are designed to forward Layer 2 frames within the same VLAN. When a Layer 2 broadcast frame is received on a switch port, the switch will forward the frame out to all other ports within the same VLAN, allowing all devices within the VLAN to receive and process the frame.
In summary, Layer 2 broadcast frames are processed by all devices on the same VLAN, discarded by routers that connect to multiple VLANs, and relayed by switches to devices on the same VLAN.
