As part of the learning process, a switch will flood the single frame out all of its other ports when it cannot find the destination MAC address in the switch’s lookup table.
If a broadcast frame is received with a destination MAC address ff ff ff ff ff ff, the switch forwards the broadcast frame out all of the other ports.
so, correct answer should be 3.
for option 2 the term used is broadcasting and for option 3 the term used is flooding.
but my understanding of the difference between flooding and broadcasting is not clear.
Any one having clear concept about these two terms please share...
