Question 36

old_alter_tableis 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, but the table definition remains unchanged.

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 and the table definition is changed.

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

Question 37

You are no longer able to log in to an existing MySQL Server because the root password credentials not working. You need to reset the root password to complete various administrative tasks.
What are the two major methods that will achieve this?

A.Start the MySQL Server in --safe-mode, which only loads the privilege system for changes as data is inaccessible.

B.Start the MySQL Server with reset-root-password in my.cnf, which will prompt you to enter a new root user password.

C.Start the MySQL Server with --init-file pointing to SQL that executes an ALTER USER statement to change the root user password.

D.Start the MySQL Server with --skip-grant-tables and execute SQL, which will update the root password.

E.Start the MySQL Server with -initialize-insecure to force a password reset procedure on the command line.

Question 38

After analysis on the slow query log on a high-end OLTP service, the table identified in the slow queries is:

What are the two most likely reasons for the slowness given this output?

A.Dateshould be a TIMESTAMPfield for better performance.

B.The User field is too long for most names.

C.Using default values for DATETIMEcauses table scans.

D.The engine type is not appropriate to the application use.

E.No indexes are defined.

Question 39

You are using the Performance Schema to investigate replication on a slave which has a single master. The option slave-parallel-typeis set to DATABASE.

Assume that all instruments and consumers are enabled and all threads are instrumented.
Which two facts can be concluded from the given output? (Choose two.)

A.At most, two schemas are being updates concurrently.

B.The salve has two intermediate relay slaves connected to it.

C.The slave cannot process the relay log fast enough to use all threads.

D.THREAD_ID 21has stopped running.

E.The slave is configured with slave_parallel_workers= 4

F.The server needs more cores to use all slave threads.

Question 40

Consider the index information for the dept_emptable in the employee's schema:

Which two conclusions can be made based on the output of the query?

A.The secondary indexes are optimized for unique key look-ups.

B.There are three indexes on the table.

C.The selectivity of the dept_nocolumn is the best of the indexed columns.

D.The values on the emp_nocolumn must be unique.

E.There is a redundant index on the dept_nocolumn.

F.There is a redundant index on the emp_nocolumn.
