An Administrator Is Defining a VSX LAG on a Pair

An administrator is defining a VSX LAG on a pair of AOS-CX switches that are defined as primary and secondary. The VSX LAG fails to establish successfully with a remote switch; however, after verification, the remote switch is configured correctly. The administrator narrows down the problem to the configuration on the AOS-CX switches. What would cause this problem?

A) Local optimization was not enabled on the VSX LAG
B) The VSX LAG hash does not match the remote peer
C) The VSX LAG interfaces are in layer-3 mode
D) LACP was enabled in active mode on the VSX LAG
