You have table 'apps','userdata' on server that uses MyISAM storage engine.
You want to transfer this data to server but use InnoDB engine instead. You execute the following commands: ServerB commands:

B.It ensures that unique indexes have no conflicts when the data is dumped
C.It orders by primary key to assist in speeding up importing to InnoDB tables
D.It must be specified so index data is dumped correctly when –on-create-info is used

D.It deletes all binary log files after 'mysql-bin.010'
A.The snapshot size will continue to grow as changes to the volume are made
B.The snapshots take a significant amount of disk space as they are a duplicate copy of the data
C.The system can only support one snapshot per volume, and you need to remove it to be able to take your next backup
