The PortFast feature allows the port to enter the forwarding state immediately, bypassing the listening and learning states.
As the name says, BPDU filter filters BPDUs in both directions. BPDU filter will prevent inbound and outbound BPDU but will remove portfast state on a port if a BPDU is received. Enabling BPDU filtering on an interface is the same as disabling spanning tree on it and can cause spanning-tree loops.
On the other hand, BPDU Guard keeps an eye open for any BPDU’s entering the interfaces that are enabled this feature. The port will disable as soon as the first BPDU is received, by shutting the port down.
You’are right.
UplinkFast provides fast convergence after a direct link failure and achieves load balancing between redundant Layer 2 links using uplink groups.
correct answer :
BPDU Guard
BPDU Filter
Uplink Fast
Portfast
Root Guard

Jay is right
Agree with Jay !
I’m pretty sure these answers are wrong
I believe it is
BPDU Guard
BPDU Filter
PortFast
UplinkFast
Root Guard
It should be
BPDU Guard
BPDU Filter
UplinkFast
PortFast
Root Guard
