1Z1-888 Exam Questions Answered: Oracle Candidates' FAQ

Oracle MySQL 5.7 Database Administrator Sample Questions:

Question 1

You have been tasked with creating a QA MySQL instance on a DB host, which already has one large instance in /var/lib/mysql/running as the mysqluser. The MySQL configuration file for the existing instance includes:

The default instance was installed using the OS package manager. The latest binaries for both client and server are already in ENV PATH.
The new instance will run as a different user from the existing instance for security purposes.
You create the new data directory successfully and move on to initialize the new DATADIR.
You verify the output to confirm the operation's success:
[mysqlQA@linux /var/lib/]$ mysqld --initialize --datadir=/var/lib/mysql_QA 2>&1 | tail -n3
2018-05-03T12:16:10.928809Z 0 [ERROR] Could not open file '/var/log/mysqld.log' for error logging:
Permission denied
2018-05-03T12:16:10.928841Z 0 [ERROR] Aborting
[mysqlQA@linux /var/lib/]$
The initialization of the instance has failed.
What would you do to enable the initialization to succeed?

A. Pass --log-error=/var/lib/mysql_QA/mysqld.log.
B. Use mysql_install_db.
C. Change permissions on /var/log/mysqld.log to allow writes.
D. Use --no-defaults to ignore the existing config file in the default PATH.

Question 2

A simple master-to-slave replication is currently being used. This information is extracted from the SHOW SLAVE STATUS output:

You execute a `SHOW CREATE TABLE mytable" on the slave:

The table mytable on the slave contains:

You have issued a STOP SLAVE command. You have determined that it is safe to skip the transaction in this case. 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 GTID_NEXT="CONSISTENCY";
BEGIN; COMMIT;
SET GTID_NEXT="AUTOMATIC";
B. SET GLOBAL SQL_SKIP_SLAVE_COUNTER=1
C. SET GTID_EXECUTED="5da6b4f5-6f60-11e8-b2d6-0010e05f3e06:8";
D. SET GLOBAL enforce_gtid_consistency=ON
E. SET GTID_NEXT="5da6b4f5-6f60-11e8-b2d6-0010e05f3e06:8"; BEGIN; COMMIT; SET GTID_NEXT="AUTOMATIC";

Question 3

While attempting to set up a new replication slave on host `192.168.0.25' with the user `replication', you encounter this error:

What should you do to resolve this error?

A. Add the user [email protected] with the correct password to the master.
B. Add the user [email protected] with the correct password to the slave.
C. Edit the my.ini file on the slave so that the master-host variable is equal to the IP address of the master, and restart the slave.
D. Edit the DNS table on the master to include the domain name for the IP address of 192.168.0.25.

Question 4

You want to create the first configuration file for a new installation of MySQL.
- You will start mysqldmanually (not automate it to start when the host machine starts or execute as a service).
- You will stop mysqldusing mysqladmin.
- You will interact with mysqldby using only the command-line client mysql.
Which option identifies a maximal set of sections where you can put the "max_allowed_packet=16M" parameter without creating a problem?

A. [mysqladmin]
B. [mysql] and [mysqld]
C. [mysqld]
D. [mysql] and [mysqladmin]
E. [mysql]
F. [mysql] and [mysqld] and [mysqladmin]
G. [mysqld] and [mysqladmin]

Question 5

You are setting up a new installation of MySQL Server 5.7 (a GA release.) You have used a ZIP or TAR package to ensure that the mysqld binary, along with its support files, such as plug-ins and error messages, now exist on the host. Assume that the default datadir exists on the host. You installed the binary in the default location (the default --basedir value) for your operating system. Which step should you perform before defining your own databases and database tables?

A. Register mysqld as a service that will start automatically on this host machine.
B. Execute a command with a minimal form of: mysql --initialize
C. Create additional login accounts (so that everyone does not need to log in as root) and assign them appropriate privileges.
D. Create a configuration file containing default-storage-engine=InnoDB.
E. Set an exception in the host machine's firewall to allow external users to talk to mysqld.
