Which set of actions will allow you to free disk space back to the file system?
You want to create the first configuration file for a new installation of MySQL.

Which option identifies a maximal set of sections where you can put the "max_allowed_packet=16M" parameter without creating a problem?
You have just executed a manual backup by using this command:
mysqlbackup -u root -p --socket=/tmp/my.sock --backup-dir=/my/backup/ backup The operation completed without error.
What is the state of this backup and operation required before it is ready to be restored?
Consider the key buffer in a MySQL server. Which two statements are true about this feature?
This output is from a SHOW SLAVE STATUS:
