Given the information in the following figure, which statement is true when Computer A needs to communicate with Computer F?
Answer Options
Switch A and Switch B will flood the frame across all ports.
Only Switch A will flood the frame across all ports.
Only Switch B will flood the frame across all ports.
Switch A will flood the frame across all ports; Switch B will forward traffic only to Computer F's port.
Correct Answer: B
Explanation
Since the MAC address table is empty on Switch A, Switch A will flood the frame to all ports on the switch. This will include the router attached to interface Fa0/3. However, a router does not perform forward/filter decisions, so the frame will not be flooded any further on Router A. Switch A will forward the frame to all ports, but the router will not forward the frame onto the segment where Switch B is located. Switch B will never see the frame from Switch A because Router A segments the two networks.
