By using the 'nodetool repair' command before taking a snapshot.

None

Using the 'nodetool flush' command before taking a snapshot ensures that all in-memory writes are flushed to disk, providing a consistent snapshot across all nodes.

What is the purpose of the 'nodetool clearsnapshot' command in Cassandra?

To reset the node's configuration to default.

To delete all snapshots for a specific keyspace or the entire cluster.
