Demo Questions
Question 1
By using the asynchronous MySQL Replication architecture, data can be replicated to slaves. Identify three use cases of MySQL Replication.
- MySQL Replication Connector/J (ReplicationDriver) is provided to allow read capability on slave and write capability on master.
- MySQL Enterprise Backup will back up from Slave automatically.
- It provides multi-master access where the application can write and read data across the database servers.
- It allows backup to be done on the slave without impacting the master.
- You can create a slave server for reporting applications, which get only read access to the slave servers. It off-loads the master server. Additional servers allow different database server configuration.
Correct answer: BDE
Question 2
You get a Maintenance notification about your Oracle MySQL Cloud Service. What are the implications?
- There are no maintenance operations planned. You need to do them manually.
- Depending on the planned outage, you may not be affected by it. You need to read the maintenance details in the support notice.
- You need to agree to the maintenance windows. If not, you are not affected by the outage.
- You can expect an outage of your MySQL Cloud Service during the planned time.
Correct answer: D
Question 3
You use MySQL Enterprise Monitor for a group of MySQL servers. In recent weeks, the MySQL Enterprise Monitor has slowed down significantly.
Which two preventative actions should you take if your number of monitored MySQL instances has changed?
- Increase the disk space with at least 10% of the database size.
- Increase the necessary operating system swap space (Linux): mkswap /dev/sdx; swapon/dev/sdx, /etc/fstab.
- Increase the amount of RAM available to the JVM installed with Tomcat. The JVM memory settings are defined by the JAVA_OPTS line of the setenv file, which sets the environment variables for Tomcat (--JvmMs/-Xms and –JvmMx/-Xmx).
- Tune the InnoDB Buffer Pool of the MySQL Enterprise Monitor Repository database. This can have a significant impact on performance (innodb_buffer_pool_size).
