A data center engineer bundles four interfaces into a port-channel between a Nexus 9000 and a downstream server using LACP. The requirement is that if fewer than three member links are operational, the entire port-channel must go down rather than forward traffic on the remaining links. Additionally, if the server sends no LACP PDUs on a member interface, that interface must NOT independently forward traffic as a standalone access port. Which combination of configuration achieves both requirements?
