Q2. A simple master-to-slave replication is currently being used. The following information is extracted from the SHOW SLAVE STATUS output:
Last_SQL_Error: Error 'Duplicate entry '8' for key 'PRIMARY' ' on query. Default database:
'mydb'. Query: 'insert into mytable VALUES ('8' , 'George') '
Retrieved _Gtid_Set: 38f32e23480a7-32a1-c323f78067fd37821: 1-8
Auto _Position: 1
You execute a “SHOW CREATE TABLE mytable” on the slave:
CREATE TABLE ‘mytable’ (
‘ID’ int(11) NOT NULL DEFAULT ‘0’,
‘name’ char(10) DEFAULT NULL,
PRIMARY KEY (‘ID’)
The table mytable on the slave contains the following:
You have issued a STOP SLAVE command. One or more statements are required before you can issue a START SLAVE command to resolve the duplicate key error.
Which statement should be used?
A. SET GLOBAL SQL_SKIP_SLAVE_COUNTER=1
B. SET GTID_NEXT=”CONSISTENCY”;
SET GTID_NEXT=” AUTOMATIC’;
C. SET GLOBAL enforce_gtid_consistency=ON
D. SET GTID_EXECUTED=”38f32e23480a7-32a1-c323f78067fd37821 : 9”;
E. SET GTID_NEXT=”38f32e23480a7-32a1-c323f78067fd37821 : 9”;
Q3. Which three methods will show the storage engine for the Country table?

B. Using the statement RESET PERFORMANCE CACHE;
C. Using the statement FLUSH PERFORMANCE CACHE;
D. Using TRUNCATE statements, for example, TRUNATE TABLE performance_schema.events_waits_current;
E. Disabling and re-enabling all instruments
F. Restarting Mysql
Q6. Full Atomicity, Consistency, Isolation, Durability (ACID) compliance is a necessity for a new
application, which heavily reads and writes data.
This requires the following config file options:
However, this configuration is expected to introduce disk I/O overhead.
What three changes will reduce disk I/O overheads?
A. Use of soft links for database directories on the same physical disk
B. Use of separate directories on the same physical disk for log files and data files
C. Placement of InnoDB log files and datadir on separate physical disks
D. Allocation of RAM to the buffer pool such that more of the data can fit in RAM
E. Use of delay_key_write=ON for batch index update
Q7. You have forgotten the root user account password. You decide to reset the password and execute the following:
Shell> /etc/init.d/mysql stop Shell> /etc/init.d/mysql start – skip-grant tables Which additional argument makes this operation safer?
A. --skip-networking, to prohibit access from remote locations
B. --reset-grant-tables, to start the server with only the mysql database accessible

B. Running the server with – skip-networking specified
C. Limiting logins to originate from the application server or the server’s subnet
D. Starting the server with – bind- address=0.0.0.0 specified
