A network engineer wants to prevent unauthorized devices connected to certain access ports from affecting the spanning tree topology by sending BPDUs. The ports should be shut down automatically if any BPDUs are detected. Which feature should be configured on these interfaces?
Loop Guard
BPDU Filter
Root Guard
BPDU Guard
BPDU Guard should be configured on these interfaces. BPDU Guard protects the network by disabling a port (placing it in an err-disabled state) if a BPDU is received on a PortFast-enabled access port. This prevents unauthorized devices from participating in the spanning tree and potentially causing topology changes. Root Guard prevents a port from becoming a root port but doesn't disable the port upon receiving BPDUs. Loop Guard helps prevent loops by monitoring the receipt of BPDUs on non-designated ports but doesn't shut down the port if BPDUs are received. BPDU Filter suppresses the sending and receiving of BPDUs but doesn't disable the port when a BPDU is detected, which doesn't meet the requirement.
