A switch with the MAC FDB shown in the exhibit receives an Ethernet frame with source MAC address 00:00:8c:01:00:0a and destination MAC address ff:ff:ff:ff:ff:ff. On which ports is the frame forwarded?
B. On all ports except 1/1/1
Explanation:
Source MAC: 00:00:8c:01:00:0a → already associated with port 1/1/1, so the switch updates (or confirms) this entry in its MAC forwarding table.
Destination MAC: ff:ff:ff:ff:ff:ff → this is a broadcast address.
Broadcast Behavior:
When a broadcast frame is received:
The switch forwards it out all ports except the one on which it was received.
In this case, the frame arrived on port 1/1/1, so it is forwarded out:
✅ 1/1/2
✅ 1/1/3
✅ 1/1/4
