Question 2

You have a MySQL Server instance (running with Port# 3306) monitored by the Service Manager in MySQL Enterprise Monitor. You cloned the MySQL Database instance and configured it to be a replicated MySQL instance as Slave using Port# 3316 on the same machine as the Master Server. The replication configuration is working correctly. The Master and Slave Servers are running.
You are trying to add the newly created MySQL Slave instance to the Monitor. The Service Manager in MySQL Enterprise Monitor notifies you that the new instance is successfully added; however, it is not added correctly at the newly added configuration points to the old Master monitored items. The Monitor shows only one monitored MySQL instance for Master and Slave.
Identify two reasons for this problem.

A. The MASTER and SLAVE are grouped as one instance for monitoring.
B. All the MySQL instances (Master and Slave) have the same server_uuid in <datadir>/auto.cnf.
C. The mysql.instance table on SLAVE is cloned with the same content as MASTER, which has the same server UUID.
D. The SLAVE and MASTER instances are started with the same configured value for the option - - monitor_server_uuid.
E. The mysql.inventory table on SLAVE is cloned with the same content as MASTER, which has the same server UUID.

You create two database tables as shown by the following CREATE TABLE statements:
CREATE TABLE parent (
parent_id INT,

PRIMARY KEY (parent_id)
);
CREATE TABLE child (
child_id INT,
parent_id INT,
name_first VARCHAR(30),
name_last VARCHAR(30),
PRIMARY KEY (child_id)
);
After populating both tables with data, which statement would produce an output of only the parents' first and last names and the first and last names of the related children?

A. SELECT p1.name_first, p1.name_last, c1.name_first, c1.name_last FROM parent p1 LEFT JOIN child c1 ON (c1.parent_id=p1.parent_id);
B. SELECT name_first, name_last FROM parent, child LEFT JOIN parent_id WHERE parent_id = child_id;
C. SELECT * FROM parent, child LEFT JOIN (child) ON (child.parent_id=parent.parent_id);
D. SELECT * .name_first, *.name_last FROM BOTH parent, child WHERE parent_id IS EQUAL;
