Question 1

You have an InnoDB Cluster configured with three servers.

Examine this command, which executes successfully:

mysqldump -uroot -p -d mydatabase > mydatabase_backup.sql

Due to data loss, the cluster is initialized and a restore is attempted resulting in this error:

ERROR 13176 (HY000) at line 23: Cannot update GTID_PURGED with the Group Replication plugin running

Which two actions, either one of which, can fix this error and allow a successful restore of the cluster? (Choose two.)

A : Stop all instances except the primary read/write master instance and run the restore.

B : Remove the @@GLOBAL.gtid_purged statement from the dump file.

C : Create the backup by using the --set-gtid-purged=OFF option.

D : Remove the group replication plugin from each instance before restoring.

E : Remove the @@GLOBAL.gtid_executed statement from the dump file.

F : Restore using the --set-gtid-purged=OFF option.

Answer: B,C

Question 2

Examine this MySQL client command to connect to a remote database:

Question 4

You execute mysqladmin shutdown on a MySQL server that is decribed as follows:

- It is running with both active and idle client connections.

- It has open transactions against InnoDB.

- It has active multi-row inserts into MyISAM engine tables.

- Innodb_fast_shitdown is set to 1.

What are three effects of shutting down the server by using a mysqladmin shutdown command?

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.

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?

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.

C : The slave relay logs should be deleted; execute CHANGE MASTER to adjust the replication relay log file name, then issue start SLAVE;

D : The slave needs to be restored from backup.
