                              • A. The incorrect logical unit for the ge-1/1/2 interface is configured under the OSPF hierarchy.
                              • B. The ge-1/1/2 interface is configured under the wrong OSPF area.
                              • C. The metric configured on ge-1/1/2 is not valid.
                              • D. The interface-type is not configured properly on the ge-1/1/2 interface.
