Question 1

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.

Answer: B

Question 2

You are using the Performance Schema to investigate replication on a slave which has a single master.

The option slave-parallel-type is set to DATABASE.

Assume that all instruments and consumers are enabled and all threads are instrumented.

Which two facts can be concluded from the given output? (Choose two.)

A : The salve has two intermediate relay slaves connected to it.

B : The slave is configured with slave_parallel_workers= 4.

C : At most, two schemas are being updates concurrently.

D : THREAD_ID 21 has stopped running.

E : The slave cannot process the relay log fast enough to use all threads.

F : The server needs more cores to use all slave threads.

Answer: A,B

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? (Choose two.)

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 4

You have just created a replication slave from a backup of the master made with mysqldump:

2020-03-14-14-37-11-4ec4153145d3e66368ed58ed6f5922f5

You try to log in to the slave with the application user, but fail as follows:

The login works on the master.

Which two changes to the process can fix the issue?

A : After the restore, log in to the database and execute FLUSH PRIVILEGES.

B : Use the --flush-privileges with mysqldump.

C : Add a second dump for the 'mysql' database; --all-databases does not include it.

D : Use the --grants option to include GRANT statements in the dump.

Answer: B

Question 5

Examine the output:

Other-Image-30e9b1e03-8bbc-4275-a4c0-1ac8f11994b9

What statement is true about the start attempt?

A : MySQL server was not started due to a problem while executing process 2732.

B : MySQL server continued to start up even though another process existed.

C : systemd found the mysqld service disabled and failed to start it.

D : systemd waited for 30 seconds before timing out and start up failed.

E : systemd attempted to start mysqld, found another systemd mysqld process running, and shut it down.
