Network Implementation第 41 / 100 题
An engineer configures a switch port that should immediately transition to forwarding for a single end host. Which STP feature is appropriate?
a.Root guard
b.BPDU flooding
c.PortFast
d.Trunk negotiation
解析
PortFast lets an access port skip the listening and learning states and move directly to forwarding, which is safe for ports connected to a single end device. It should not be enabled on ports connected to other switches. BPDU guard is often paired with it for protection.
