Question 96

Which two methods will provide the total number of partitions on a table? (Choose two.)

A.Query the INFORMATION_SCHEMA.PARTITIONS table

B.Use the command: SHOW TABLE STATUS

C.Query the performance_schema.objects_summary_global_by_type table

E.Use the command: SHOW CREATE TABLE

Question 97

An existing master-slave setup is currently using a delayed replication of one hour. The master has crashed and the slave must be "rolled forward" to provide all the latest data.
The SHOW SLAVE STATUSindicates these values:
* RELAY_LOG_FILE=hostname-relay-bin.00004
* RELAY_LOG_POS=1383
Which command set would make the slave current?

A.STOP SLAVE; CHANGE MASTER TO MASTER_DELAY=0; RELAY_LOG_FILE = `hostname-relay- bin.00004', RELAY_LOG_POS = 1383;

B.STOP SLAVE; CHANGE MASTER TO RELAY_LOG_FILE = `hostname-relay-bin.00004', RELAY_LOG_POS = 1383;

C.STOP SLAVE; SET GLOBAL master_delay=0; START SLAVE;

D.STOP SLAVE; CHANGE MASTER TO MASTER_DELAY=0; START SLAVE;

Question 98

Consider the two partial outputs of the SHOW GLOBAL VARIABLEScommand from a master and slave server:
Master:

Slave:

There is a problem with the slave replicating from the master. Which statement describes the cause of the problem?

A.server_idis not unique.

B.The shared_memory_base_namevariable must match the master.

C.The log_binvariable is set to OFF on the slave.

D.The version of the slave is newer that the version of the master.

E.The max_connectionsvariable on the slave needs to be increased.

Question 99

This output is from a SHOW SLAVE STATUS:

What would cause the SQL_Delay variable to have a value of 360?

A.The master has performed a large transaction, which will take 360 seconds to complete on the slave.

B.The network latency between the master and the slave is 360 milliseconds.

C.The slave will need an estimated 360 seconds to update the remaining contents from the relay log.

D.The slave was configured for delayed replication with a delay of six minutes.

Question 100

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?

A.The .mylogin.cnf file is not readable.

B.The DNS is not configured correctly for slave1 host.

C.There is no password defined in the login path.

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