D. Unless the Switch is configured for rapid spanning tree or portfast then the port will go through 20 seconds of blocking, 15 seconds of listening, and 15 seconds of learning before it starts forwarding frames.

D) 50s. By default a catalyst switch use pvst, so the port stay 20s on blocking stat, 15s on listening, 15s on learning and then forwarding. In rapid pvst the delay decrease by 15 s because no lisenting stat

C; The port is going through Listening (15 sec) and Learning (15 sec) states.

C. 30 due to STP - if you want to reduce it to 0 then portfast must be enable\configured.

0 Seconds make no sense since things take some time to even start and transfer packets. 50 seconds sound too long to pull it off. Waiting near a minute to start forwarding traffic would not make people happy 15 seconds feels closer, but I don't think that is possible so far I would say 30 seconds to make logical sense

If its still in classic STP or PVSTP it takes 50 seconds but if its RSTP or PVRSTP then it takes 30 seconds.

50 sec. 15 to listening,15 to learning,20 to learn mac add so 50 sec total.

CCNA Question of the Day: You connect a laptop to an available port on a Cisco Catalyst switch. By default, how long does it take that port to start forwarding traffic? Comment below!
