What is one difference between BPDU protection and root guard?
A. BPDU protection works with RPVST+, RSTP, and MSTP. Root guard works with RSTP or MSTP, but not RPVST+.
B. BPDU protection blocks a port if it receives any BPDU, but root guard blocks a port only if the BPDU indicates a better root path.
C. BPDU protection is typically implemented on edge ports, but root guard is typically implemented on uplinks with the root port role.
D. BPDU protection drops BPDUs received on a port, but does not block the port. Root guard blocks the port if it receives a BPDU.
