Do you mean the mysql system database, or a specific database/table that's in the NDB cluster engine? The mysql system database falls outside of the cluster realm, so each server has its own independent copy.

I would say though that for most purposes, you probably don't want to use NDB Cluster. It is suitable for very specific use cases, and is 'abused' in other situations.
These days, there are better solutions for many cases, including Galera cluster which is a synchronous replication mechanism in MariaDB 5.5 (-cluster) and above. It's not available in stock (Oracle) MySQL.

What do you mean by running MySQL in cluster mode - MySQL Cluster? If so then the data is stored in the data nodes rather than the MySQL Servers and so if bad data is written to one MySQL Server then that same bad data will be viewed through the other MySQL Server too.

if you set up your LAN MySQL server in to cluster, will it make the new data's entered on a laptop MySQL database that is not connected on the LAN synchronize with the cluster, once that laptop got connected with the LAN again? Is it also possible to set up a cluster on a web host MySQL, so that when you log in on the online database, your offline data will synchronize with the MySQL cluster on your web host?
