D is OK
Disaster recovery
Occasionally, auto roll-back from a bad configuration fails, and MM-MC connectivity remains disrupted. In this case, you can enable Disaster Recovery mode on the MC using the command disaster-recovery on. You have full control of the /mm node, so you can make local modifications on each MC to restore MM-MC connectivity.
I bet is D, if the network administrator previusly had configured auto recovery on the MM he wouldnt have this problem.
I am genuinly confused between C and D .. because I think both of them are correct
