Question 1

Consider the index information for the dept_emp table in the employee’s schema:

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

There are three indexes on the table.
There is a redundant index on the dept_no column.
The secondary indexes are optimized for unique key look-ups.
The values on the emp_no column must be unique.
The selectivity of the dept_no column is the best of the indexed columns.
There is a redundant index on the emp_no column.

Correct answer: CF

Question 2

Which two statements are true about InnoDB auto-increment locking?

InnoDB never uses table_level locks.
InnoDB always protects auto-increment updates with a table-level lock
InnoDB does not use locks to enforce auto-increment uniqueness.
The auto-increment lock can be a table-level lock.
Some settings for innodb_autoinc_lock_mode can help reduce locking.

Correct answer: DE

Question 3

You want to create a temporary table named OLD_INVENTORY in the OLD_INVENTORY database on the master server. This table is not to be replicated to the slave server.

Which two changes would ensure that the temporary table does not propagate to the slave?

Set binlog_format=MIXED with the --replicate-ignore-temp-table option.
Use the --replicate-do-db, --replicate-do-table, or --replicate-wild-do-table option with the value equal to OLD_INVENTORY.
Change the binlog_format option to ROW and restart mysqld before you create the OLD_INVENTORY table.
Stop SQL_THREAD on the slave until you have finished using the OLD_INVENTORY temporary table.
Use the --replicate-ignore-table option with the value equal to OLD_INVENTORY.OLD_INVENTORY and restart mysqld before creating the temporary table.

Correct answer: BE

mysql_config_editor is the only MySQL-provided utility that can print the values stored in .mylogin.cnf.
A .mylogin.cnf file can store at most one login path.
It provides a FIPS-compliant keyring for storing MySQL login details.
A .mylogin.cnf file can be edited using a text editor, such as vim or Notepad++.
It is an alternative to storing the MySQL login details in a my.cnf file.
It provides means to help avoid accidentally exposing the MySQL login details.
