Suggested Answer: C 🗳️
BPDU Guard puts a portfast port in err-disabled in case of receiving a BPDU. But root guard is a feature specially designed in order to enforce the root bridge placement in the network forcing an interface to become a designated port to prevent surrounding switches from becoming a root switch.
