Q27. 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.

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”;
Q28. Compare a typical Distributed Replicated Block Device (DRBD) with MySQL Standard Replication using master-slave replication.
Which two statements are correct?

A. Each extra column in the copy with more columns must not have a default value.
B. Columns that are common to both versions of the table must be defined in the same order on the master and the slave.
C. The slave database cannot have more columns than the master. Only the master database can have more columns.
D. Columns that are common to both versions of the table must come first in the table definition, before any additional columns are additional columns are defined on either server.
E. The master database cannot have more columns than the slave. Only the slave deatbase can have more columns.
