 Snapshots can be viewed remotely using any Kubernetes client by listing or describing cluster-scoped `ETCDSnapshotFile` resources.
 Unlike the `rke2 etcd-snapshot list` command, which only shows snapshots visible to that node, `ETCDSnapshotFile` resources track all snapshots present on cluster members.

 To rotate CA certificates and keys, use the `rke2 certificate rotate-ca` command.
 This command performs integrity checks to confirm that the updated certificates and keys are usable.
 If the updated data is acceptable, the datastore's encrypted bootstrap key is updated, and the new certificates and keys will be used the next time RKE2 starts.

 The `rke2 token rotate` command allows you to rotate and replace the original token used for server bootstrap. After running the command on a single server, all servers and agents that used the original token should be restarted with the new token. The original token will be invalidated and cannot be used to join any new servers or agents to the cluster.
