Exam 200-301 topic 1 question 256 discussion

• Interfaces with portfast enabled that come up will go to forwarding mode immediately, the interface will skip the listening and learning state. • A switch will never generate a topology change notification for an interface that has portfast enabled. https://networklessons.com/switching/cisco-portfast-configuration

C&D are correct for sure :)

From studies, C is right.

For the exam which one will be the correct answer the most voted or this answers ?

Makes the STP process faster.

Cisco Learning Network > CCNA Certification Community: portfast Post by Elvin Arias Soto "The Portfast feature is used on access ports to bypass the listening and learning states of STP, meaning that a port shoud inmediately go to forwarding state, note that a Portfast enabled port also do not generate Topology Change Notifications (TCNs). The reason why the port is not going to forwarding is becuase Portfast has two variants, one for access ports and one for trunks. In order to enable Portfast on trunk ports you should enter the "spanning-tree portfast trunk" command on interface mode. ..."

C and D

C and D

Portfast does two things for us: Interfaces with portfast enabled that come up will go to forwarding mode immediately, the interface will skip the listening and learning state. A switch will never generate a topology change notification for an interface that has portfast enabled. https://networklessons.com/switching/cisco-portfast-configuration
