NEW QUESTION 71
Which two statements describe how InnoDB recovery works? (Choose two.)

InnoDB handles most crash recoveries automatically.

InnoDB blocks some operations when innodb_force_recoveryis set to greater than 0.

There will in general be lost committed transactions after a crash using the default settings.

It is required to enable binlog_gtid_simple_recoveryto perform a crash recovery.

It is recommended to set innodb_force_recovery = 1as part of normal operations.

It is always required to enable innodb_force_recoveryto perform a crash recovery.

NEW QUESTION 72
What are three methods to reduce MySQL server exposure to remote connections? (Choose three.)

using SSL when transporting data over remote networks

using the sql_mode=STRlCT_SECURE after connections are established for encrypted communications

setting –skip-networking when remote connections are not required

setting specific grant privileges to limit remote authentication

setting –mysql_secure_configuration to enable paranoid mode

NEW QUESTION 73
You have created a new user with this statement:
CREATE USER ‘erika’@’localhost’ IDENTIFIED BY ‘first#1Pass’ PASSWORD EXPIRE; What is the outcome?

When ‘erika’@’localhost’tries to log in with the MySQL command-line client, the user will have to change the password before seeing the mysql>prompt.

When ‘erika’@’localhost’tries to log in with the MySQL command-line client, the user will not be permitted to log in because the password is expired.

When ‘erika’@’localhost’tries to log in with the MySQL command-line client, the user will be permitted to log in but will not be able to issue ant statements until the user changes the password.

You receive a syntax error that indicates that you cannot set a password and expire it at the same time.

NEW QUESTION 74
The /myfolder/my.cnffile has option set:
[mysqld]
skip-log-bin
myfolder2/my.cnfhas this option set:
/
[ mysqld]
log-bin = /valid/path/to/mysqlbinlog
All mentioned paths are accessible to the account that you are currently using. Assume that any other options mentioned in either file are valid and legal option definitions.
You start an instance by using this command line:
mysqld –defaults-file=/myfolder/my.cnf –defaults-extra-file=/myfolder2/my.cnf What is the outcome?

MySQL starts and Binary Logging is enabled.

MySQL fails to start due to the conflicting options in the configuration files.

MySQL fails to start due to conflicting options on the command line.

MySQL starts but Binary Logging is disabled.

NEW QUESTION 75
What are three typical causes of MySQL becoming suddenly slow and unavailable? (Choose three.)

A configuration change was made.

The hardware includes a single point of failure.

Monitoring has not enabled all Performance Schema instruments.

The MySQL Query Cache is disabled.

OPTIMIZE TABLE is not executed for the InnoDB tables.

The application executes a new untested query.

NEW QUESTION 76
A MySQL Server has been running an existing application successfully for six months. The my.cnf is adjusted to contain this additional configuration:

The MySQL Server is restarted without error.
What effect will the new configuration have on existing account?

They are not affected by this configuration change.

They all connect via the secure sha256_password algorithm without any configuration change.

They will have their passwords updated on start-up to sha256_password format.

They will have to change their password the next time they login to the server.

NEW QUESTION 77
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.

NEW QUESTION 78
Consider the key buffer in a MySQL server. Which two statements are true about this feature?

It caches index blocks for MyISAM tables only.

It caches index blocks for all storage engine tables.

It is a global buffer.

It is set on a per-connection basis.

It caches index blocks for InnoDB tables only.

NEW QUESTION 79
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?

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

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

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

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

NEW QUESTION 80
Host slave1 has ip address 192.0.2.10.
Host slave2 has ip address 203.0.113.50
Examine these commands:

Why did this error occur?

The host on the command line is not defined in the login path.

The mysqld instance has not been restarted after creating the login path.

There is no password defined in the login path.

The DNS is not configured correctly for slave1 host.

The .mylogin.cnf file is not readable.

NEW QUESTION 81
An admin attempts to enforce stronger security by using these commands:

The admin then leaves the system running with the specified changes. What are two remaining security concerns?

validate_password_policy cannot be set without restarting the MySQL instance.

The name of the dictionary file is too obvious.

The dictionary file word list is too short.

validate_password_dictionary_file cannot be set without restarting the MySQL instance.

The validate_password plug-in has not been loaded.

The dictionary file is an insecure location.

NEW QUESTION 82
Consider the table people with the definition:

The application uses a query such as:
SELECT * FROM people WHERE YEAR(Birthday) = 1980;
The query is not using an index.
Which two methods can be used to allow the query to use an index? (Choose two.)

Change the WHEREclause to Birthday BETWEEN 1980-01-01 AND 1980-12-31.

Add a functional index for YEAR(Birthday).

Execute ANALYZE TABLEto update the index statistics.

Add a generated column calculating YEAR(Birthday)and index that column.

Add FORCE INDEX (Birthday)to the query.

NEW QUESTION 83
You enable binary logging on MySQL Server with the configuration:
binlog-format=STATEMENT
log-bin
Which database updates are logged on the master server to the binary log by default?

all updates except to the TEMPDB database

all updates except to the PERFORMANCE_SCHEMA database

all updates not involving temporary tables

all updates to the default database, except temporary tables

all updates to all databases

NEW QUESTION 84
How does the InnoDB storage engine handle deadlocks when they are detected?

Both the affected transactions will be rolled back.

The affected transactions wait for innodb_lock_wait_timeout seconds, and then roll back.

One of the affected transactions will be rolled back, the other is allowed to proceed.

The transaction isolation level determines which transaction is rolled back.

The innodb_locks_unsafe_for_binlog setting determines which transaction is rolled back.

NEW QUESTION 85
To query two system variables, you execute this statement and get the results shown:

When you execute the following two statements, only the first one succeeds:
SET @@autocommit=0;
SET @@max_connections=200;
Why does the second statement fail?

max_connections is a read-only variable that cannot be set dynamically.

max_connections must be set globally instead of locally.

max_connections is a derived variable that can only be set indirectly.

max_connections must be set at server start in an options file.

NEW QUESTION 86
The MySQL user ‘adam’ currently has USAGE permissions to the database.
The football database is transactional and has non-stop updates from application users. The ‘adam’ user needs to be able to take consistent backups of the football database by using the –single-transaction option.
Which extra GRANT permissions are required for adam to take mysqldump backups?

The ‘adam’ user must also have SINGLE TRANSACTION global grant to take a consistent backup.

The ‘adam’ user needs the PROCESS privilege to be able to take a consistent backup while other users are connected.

The ‘adam’ user must have the SUPER privilege in order to take data backups.

The ‘adam’ user must also have SELECT on the football database for backup to work.
