Click on the exhibit below.

In the following diagram, traffic ingressing on SAP 1/2/3:1 will be passed to the layer-2 DPI device for inspection based on a filter policy applied to the ingress of the SAP. What feature should be enabled on SAP 1/2/1:100 and SAP 1/2/2:100 to ensure that incorrect information is not populated in the FDB of VPLS 1?

A.

Learning should be disabled on both SAPs connected to the DPI device to prevent FDB instability

B.

A MAC filter should be applied to both SAPs connected to the DPI to limit MAC learning on the port

C.

An IP filter should be applied to both SAPs connected to the DPI to prevent FDB instability

D.

The SAPs connected to the DPI should be configured with the "discard-unknown" feature to limit MAC learning on the port
