Options :

A : Connections that have an open transaction are rolled back.

B : Connections with statements running against MyISAM tables wait for completion.

C : New client connections are not accepted after shutdown is initiated.

D : Connections are accepted during the shutdown process because a graceful shutdown can take large amounts of time.

E : Partial updates may occur for non-transactional tables.

B : InnoDB

C : MyISAM

D : All the engines included with MySQL

Answer: B

Question 4

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? (Choose two.)

Options :

A : Set binlog_format=MIXED with the –replicate-ignore-temp-table option.

B : Use the –replicate-do-db, –replicate-do-table, or –replicate-wild-do-table option with the value equal to OLD_INVENTORY.

C : Change the binlog_format option to ROW and restart mysqld before you create the OLD_INVENTORY table.

D : Stop SQL_THREAD on the slave until you have finished using the OLD_INVENTORY temporary table.

E : Use the –replicate-ignore-table option with the value equal to OLD_INVENTORY.OLD_INVENTORY and restart mysqld before creating the temporary table.

Answer: A,C

Question 5

Your MySQL environment has asynchronous position based-replication with one master and one slave.

The slave instance had a disk I/O problem, so it was stopped.

You determined that the slave relay log files were corrupted and unusable, but no other files are damaged.

You restart MySQL Server.

How can replication be restored?

Options :

A : The slave relay logs should be deleted; then execute START SLAVE;

B : The relay logs from the master should be used to replace the corrupted relay logs.
