Which statement correctly describes enabling BPDU guard on an access port that is also
enabled for PortFast?

A.
Upon startup, the port transmits 10 BPDUs. If the port receives a BPDU, PortFast and
BPDU guard are disabled on that port and it assumes normal STP operation.

B.
The access port ignores any received BPDU.

C.
If the port receives a BPDU, it is placed into the error-disable state.

D.
BPDU guard is only configured globally and the BPDU filter is required for port-level
configuration.
