This is a study tool. The 3 wrong answers for each question are randomly chosen from answers to other questions. So, you might find at times the answers obvious, but you will see it re-enforces your understanding as you take the test each time.
1. On Windows this influences file copying during a binary MyISAM backup - It is such that you might not be able to copy table files for tables that are locked by the server. In these cases - you must stop the server before copying the table files

file-locking behavior
SELECT ... INTO OUTFILE
slower

MySQL server
text backup
exact copies
slower
3. During text backups the _____ must be running because it must read the files that are to be backed up
server
lower_case_table_names=1
textual backup
MyISAM
4. What program can be used to make binary InnoDB backups
MySQL server
Restoration
binary log

6. To force the use of lowercase database and table names what option can you set and what value specifically must you give it?
binary portability for InnoDB
dumping table contents to text format (using mysqldump)

internal structure
binary backup
mysqlhotcopy world /var/archive
