Question 1


If a BPDU is received on a port where BPDU guard is configured, that port is put into errdisable state (nearly the same as shutdown state) immediately. BPDU Guard is often configured on a PortFast-enabled port to prevent a switch from connecting to. When that switch begins to send BPDU to a BPDU guard port, it will be blocked immediately.

Question 2

Question 3

Question 4


The Portfast feature can be configured on both access or trunk port. This feature instructs the port to skip listening and learning state and move to forwarding state immediately.

“Skip 802.1D timers” here means “skip the listening and learning timers” so in fact these two answers have same meanings.
