Which of the following commands would you use to enable BPDU Filter on a specific interface?

The command to enable BPDU Filter on a specific interface is indeed "spanning-tree bpdufilter enable." This command is specifically designed to allow BPDU (Bridge Protocol Data Unit) filtering in a spanning tree environment. When you enable BPDU Filter on an interface, the port will stop sending and receiving BPDUs, effectively preventing the switch from participating in Spanning Tree Protocol (STP) operations on that interface. This can be particularly useful in scenarios where a port is connected to a device that should not participate in spanning tree operations, such as a host or a poorly configured switch.

Using this command helps control unnecessary STP traffic, which can improve network performance in certain situations. It also ensures that the interface does not accidentally cause topology changes that could affect the stability of the network.

The other options do not correctly represent the command syntax or functionality associated with enabling BPDU Filter. For instance, “spanning-tree bpdu guard enable” is a command that enables BPDU Guard, which is a different feature designed to protect against bridging loops by disabling a port when it receives a BPDU, rather than filtering them.
