Question 62/62
Click the Exhibit button. Switch-1 in the exhibit receives a packet from User A with a destination MAC address of 00:26:88:02:74:48. Which statement is correct?
Correct Answer: D
Explanation/Reference:
Explanation:
A switch populates its mac-address table with mac addresses registered on incoming frames. As a result, when the switch needs to forward a frame destined to that specific mac-address, it will know out of which port to send the frame. Flooding however occurs when the switch does not know of the destination mac- address? say the switch has not learnt that mac address yet; or maybe that specific entry expired so it got flushed away from the mac-address table. To ensure the frame reaches its intended destination, the switch will replicate that frame out of all ports, less the port where the frame was received that's flooding.
