문제 #1

The replication for a Master and Slave MySQL Servers is up and running. The disk space for Master Server is continuously growing. The binlog size keeps growing. Which two methods can fix the issue?

A. On the Master server, disable binlog by removing the --log-bin option.
B. Set the expire_logs_days system variable to expire binary log files automatically after a given number of days.
C. To safely purge binary log files, perform these steps:
1. On each slave server, use show slave status to check which log file it is reading.
2. Obtain a listing of the binary log files on the master server with show binary logs.
3. Determine the earliest log file among all the slaves. This is the target file. If all the slaves are up-to-date, this is the last log file on the list.
4. Make a backup of all the log files you are about to delete. (This step is optional, but always advisable.)
5. Purge all log files up to but not including the target file by using the purge binary logs statement
D. Execute the purge binary logs statement without argument.
E. Delete all binlog files manually on the file system to release storage spaces.

문제 #2

An Oracle Cloud Infrastructure customer already has many database instances configured and running in the cloud; however, they are reporting that they are unable to create any more instances.
What could be the problem?

A. The customer account might have reached resource quota/limits.
B. The customer has not kept up with their patching requirements; new instances cannot be created unless the majority or the template of existing instances are up-to-date.
C. The customer reached the database instance limit of 32.
D. The customer does not have proper user rights.

문제 #3

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.
Which two are possible reasons for this problem?

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

문제 #4

Which three prerequisites are needed for creating an Oracle Linux VM instance in the Oracle Cloud Infrastructure?

A. Custom Image
B. Object Storage
C. existing VCN
D. ssh key pair
E. bare metal Oracle Linux shape
F. subnet configured on a Virtual Cloud Network (VCN)

문제 #5

By using the asynchronous MySQL Replication architecture, data can be replicated to slaves. Identify three use cases of MySQL Replication.

A. It allows backup to be done on the slave without impacting the master.
B. MySQL Enterprise Backup will back up from Slave automatically.
C. 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.
D. It provides multi-master access where the application can write and read data across the database servers.
E. MySQL Replication Connector/J (ReplicationDriver) is provided to allow read capability on slave and write capability on master.
