Cisco CCNA 200-301 Practice Question

Enabling PortFast on switch ports allows connected end-user devices to bypass the listening and learning states and immediately enter the forwarding state. This reduces the delay when devices are connected or when the switch powers up, allowing for quicker network access.

• BPDU Guard is used to protect the network from loops by disabling a port if it receives a Bridge Protocol Data Unit (BPDU), but it does not eliminate the initial port delay.
• Root Guard prevents designated ports from becoming root ports but does not affect the port initialization delay experienced by end devices.
• UplinkFast is a feature that speeds up the transition of the backup link to the forwarding state in case of a primary link failure, relevant for uplink ports, not access ports connected to end devices.
