Select two benefits of enabling PortFast on an access port.

PortFast is a Cisco feature designed to optimize the Spanning Tree Protocol (STP) on access ports connected to end devices like workstations or servers. The primary benefit of PortFast is that it allows enabled interfaces to immediately transition to the forwarding state, bypassing the usual listening and learning states. This significantly reduces the time it takes for an end device to connect to the network, improving user experience. Another key benefit is that PortFast-enabled interfaces do not generate topology change notifications (TCNs) when they come up or go down. TCNs force all switches in the STP domain to age out their MAC address tables more quickly, which can temporarily disrupt network traffic. Since end devices don't cause topology changes that affect the STP tree, suppressing TCNs from these ports prevents unnecessary network instability. Incorrect options: "Enabled interfaces are automatically placed in listening state" is incorrect because PortFast bypasses the listening state. "Enabled interfaces wait 50 seconds before they move to the forwarding state" is incorrect; PortFast's purpose is to move to forwarding immediately, not to wait. "Enabled interfaces that move to the learning state generate switch topology change notifications" is incorrect because PortFast bypasses the learning state and suppresses TCNs.
