Cluster parameters are persisted by all shards of the cluster and by the config server as well. Specifically, these are stored into the clusterParameters collection of the config database.

A workable solution could be to have a consistency check to verify that the cluster parameter configuration is consistent across all nodes where it is persisted. SERVER-76003 keeps track of that implementation.
