One of your colleagues is trying to make a change using the mysql command-line client for his or her application session.
The colleague instant messages you this command:
mysql> SET SESSION max_connections = 200;
Why does the command fail?

• A.max_connections is not a dynamic variable. You need to change the config file and restart the database.
• B.Users can control only the max_user_connections variable.
• C.max_connections requires the GLOBAL scope.
• D.Its current user does not have the SUPER privilege.

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

• A.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.
• B.You receive a syntax error that indicates that you cannot set a password and expire it at the same time.
• C.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.
• D.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.

You have a MySQL instance with the following variables in the /etc/my.cnf file:

You issue these statements:
USE prices;
UPDATE sales.january SET amount=amount+1000;
An hour after excluding the statements, you realize that you made a mistake and you want to go to the binary log and look at the statements again.
Which statement is true? (Choose two.)

• A.Nothing is logged because you are executing an UPDATE statement that will cause changes to more than one row, and you do not have the --binlog-format value set to STATEMENT.
• B.Nothing was written to the binary log because you cannot perform a calculation in a query without enclosing the statement in single quotation marks.
• C.The changes caused by the UPDATE statement are logged to the binary log because the instance is using --binlog-format = ROW
• D.You would receive an error on the statement because you cannot update a different database that what is specified with the USE statement.
• E.The statement would fail because you cannot update more than one row at a time when using ?
  binlogformat = ROW.

You have just executed a manual backup by using this command:
mysqlbackup -u root -p --socket=/tmp/my.sock --backup-dir=/my/backup/ backup The operation completed without error.
What is the state of this backup and operation required before it is ready to be restored?

• A.Backup State = Raw Backup
  Operation = backupdir-to-image
• B.Backup State = Prepared Backup
  Operation = validate
• C.Backup State = Raw Backup
  Operation = apply-log
• D.Backup State = Compressed Backup
  Operation = copy-back
• E.Backup State = Prepared Backup
  Operation = apply-log
