Oracle MySQL 5.6 Database Administrator Sample Questions:

Question #1

Consider the three binary log files bin.00010, bin.00011, and bin.00012 from which you want to restore data.
Which method would use mysqlbinlog for greater consistency?

A. shell> mysqlbinlog bin.00010 | mysql shell> mysqlbinlog bin.00011 | mysql shell> mysqlbinlog bin.00012 | mysql
B. shell> mysqlbinlog - include-gtide=ALL bin.00010 bin.00011 bin.00012 | mysql
C. shell> mysqlbinlog - restore bin.00010 bin.00011 bin.00012
D. shell> mysqlbinlog bin.00010 bin.00011 bin.00012 | mysql

Question #2

You need to dump the data from the master server and import it into a new slave server.
Which mysqldump option can be used when dumping data from the master server in order to include the master server's binary log information?

A. Include-master-info
B. Master-binlog
C. Master-data
D. Include-log-file

Question #3

When backing up a replication slave, which three should also be backed up in addition to data?

A. Mysql.slave_relay_log_info table
B. Mysql.slave_master_info table
C. The master.info and relay.info files
D. The relay log files
E. The relay index file
F. Mysql.slave_worker_info table

Question #4

The 'allplicationdb' is using innoDB and consuming a large amount of file system space. You have a /backup partition available on NFS where backups are stored.
You investigate and gather the following information:
[mysqld] Datadir=/var/lib/mysql/ Innodb_file_per_table=0
Three tables are stored in the innoDB shared tablespace and the details are as follows: -The table data_current has 1,000,000 rows.
-The table data_reports has 1,500,000 rows. -The table data_archive has 4,500,000 rows. Shell> is -1 /var/lib/mysql/ -rw-rw---- 1 mysql mysql 744G Aug 26 14:34 ibdata1 -rw-rw---- 1 mysql mysql 480M Aug 26 14:34 ib_logfile0 -rw-rw---- 1 mysql mysql 480M Aug 26 14:34 ib_logfile1 ...
You attempt to free space from ibdata1 by taking a mysqldump of the data_archive table and storting it on your backup partition.
Shell> mysqldump - u root - p applicationdb data_archive > /backup/data_archive.sql
Mysql> DROP TABLE data_archive;
Which set of actions will allow you to free disk space back to the file system?

A. Enable compression on the table, causing InnoDB to release unused pages on disk to the file
system:
Mysql> SET GLOBLE innodb_file_per_table=1;
Mysql> SET GLOBLE innodb_file_format=Barramcuda;
Mysql> ALTER TABLE data_current ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=8;
Mysql> ALTER TABLE data_history ROW_FORMAT=COMPRESSED KEY_BLOCK_SIZE=8;
B. Execute OPTIMIZE TABLE so that the InnoDB engine frees unused pages on disk back to the
file system:
Mysql> OPTIMIZE TABLE data_current, data_reports;
C. Take a backup, stop the server, remove the data files, and restore the backup:
Shell> mysqldump - u root -p applicationdb / > /backup/applicationdb.sql
Shell> /etc/init.d/mysql stop
Shell> cd /var/lib/mysql/
Shell> rm ibdata1 ib_logfile0 ib_logfile1
Shell> /etc/init.d/mysql start
Shell> mysql - u root - p applicationdb < /backup/applicationdb.sql
D. Set the server to use its own tablespace, and then alter the table so that data is moved from the
shared tablespace to its own:
Mysql> SET GLOBAL innodb_file_per_table=1;
Mysql> ALTER TABLE data_current ENGINE=InnoDB;
Mysql> ALTER TABLE data_repors ENGINE=InnoDB;

Question #5

Which three tasks can be performed by using the performance Schema?

A. Finding client connection attributes
B. Finding queries that are not using indexes
C. Finding rows that are locked by InnoDB
D. Finding the size of each table
E. Finding the part of a code in which a single query is spending time
