What happens if a unicast frame enters a switch interface over a transmission medium A. The switch searches the MAC address table for the destination MAC address of the frame. B. The switch floods the unicast frame. C. The switch forwards the frame to the interface corresponding to the destination MAC address of the frame in the MAC address table. D. The switch discards the frame.
Question
What happens if a unicast frame enters a switch interface over a transmission medium A. The switch searches the MAC address table for the destination MAC address of the frame. B. The switch floods the unicast frame. C. The switch forwards the frame to the interface corresponding to the destination MAC address of the frame in the MAC address table. D. The switch discards the frame.
Solution
When a unicast frame enters a switch interface over a transmission medium, the following steps occur:
A. The switch searches the MAC address table for the destination MAC address of the frame. This is the first step in the process. The MAC address table is a database that the switch uses to decide where to forward frames.
B. If the switch does not find the destination MAC address in the MAC address table, it will flood the unicast frame out of all its ports except the one it received the frame on. This is known as "flooding".
C. If the switch does find the destination MAC address in the MAC address table, it will forward the frame to the interface corresponding to the destination MAC address of the frame in the MAC address table. This is the ideal scenario as it minimizes network traffic.
D. In some cases, if the switch cannot process the frame (for example, if its processing capacity is exceeded or if there is an error in the frame), it may discard the frame. This is not a common occurrence and is generally indicative of a problem.
