Question 56

old_alter_table is disabled as shown.
mysql> SELECT @@old_alter_table;

Consider this statement on a RANGE-partitioned table:
mysql> ALTER TABLE orders DROP PARTITION p1, p3;
What is the outcome of executing this statement?

A.All data in p1 and p3 partitions is removed and the table definition is changed.

B.Only the first partition (p1) will be dropped because only one partition can be dropped at any time.

C.All data in p1 and p3 partitions is removed, but the table definition remains unchanged.

D.It results in a syntax error because you cannot specify more than one partition in the same statement.

Question 57

The MySQL installation includes the mysql_config_editor utility for managing login paths stored in a
.mylogin.cnf file.
Which two are true about the login path feature? (Choose two.)

A.It provides a FIPS-compliant keyring for storing MySQL login details.

B.It is an alternative to storing the MySQL login details in a my.cnf file.

C.A .mylogin.cnf file can store at most one login path.

D.mysql_config_editor is the only MySQL-provided utility that can print the values stored in .mylogin.cnf.

E.A .mylogin.cnf file can be edited using a text editor, such as vim or Notepad++.

F.It provides means to help avoid accidentally exposing the MySQL login details.

Question 58

Suppose you are adding rows to a MyISAM table and the --datadir location runs out of disk space. What will happen when this occurs?

Question 59

A MySQL replication slave is set up as follows:

* Receives ROW-based binary logs
* Has the read-only option
The replication slave has been found in an error state.
You check the MySQL error log file and find these entries:

What are two possible causes for this error to occur? (Choose two.)

A.For tables with UNIQUE keys, statement-based replication must be used to maintain integrity.

B.The root user on the slave has executed FLUSH LOGS, causing the relay-log to doublewrite.

C.The slave was created with mysqldump -u root -p --skip-lock-tables -all-databases > / data/data.sql

D.The applications have the SUPERprivilege, which allows them to update rows.

E.The slave user does not have INSERT, UPDATE, or DELETEpermission and cannot execute the Write_rowsfunction.
