Which command is most efficient in finding the pass4SymmKey of an index cluster?

The pass4SymmKey is a security key that lets various components of Splunk Enterprise authenticate securely with one another. The pass4SymmKey for an indexer cluster is configured in the server.conf file under the [clustering] stanza. To find the pass4SymmKey of an indexer cluster, the most efficient command is C, $SPLUNK_HOME/bin/splunk btool server list clustering | grep pass4SymmKey. This command uses btool to list the effective settings for the clustering service from the server.conf file and filters the output by grep to show only the pass4SymmKey value. The other commands are either incorrect or less efficient. References :=
