Which two statements are correct about Layer 2 broadcast frames? (Choose two.)
A.
Layer 2 broadcast frames are processed by all devices on the same VLAN.
B.
Layer 2 broadcast frames are discarded by routers that connect to multiple VLANs.
C.
Layer 2 broadcast frames are relayed by routers to all connected VLANs.
D.
Layer 2 broadcast frames are relayed by switches to devices on the same VLAN.
Explanation:
1.Layer 2 broadcasts are sent to the broadcast mac address ffff:ffff:ffff if ethernet and so can be received by any device. Layer 3 broadcasts are sent to the broadcast network address, which for an ip network of 10.1.1.0/24 would be 10.1.1.255. If the IP network was over ethernet, a layer 3 broadcast would also result in a layer 2 broadcast.
2.A switch sends a layer 2 broadcast to all the ports that are in the same broadcast domain, ie the same vlan (which can be all ports). Some of those ports may have other switches connected, which will receive the broadcast on a port, and issue it out to all other ports on the same broadcast domain as the incoming port. So no, that isn’t correct.
