NEW QUESTION # 24
You want to migrate an on-premises MySQL database to a MySQL DB system on OCI.
Which method provides the least amount of application down time when switching to the DB system?

A. Store the exported data in object storage to speed up the export and import.
B. Use inbound replication to synchronize the MySQL database transactions to the DB system.
C. Run MySQL Shell on an OCI compute instance to export and import the data for faster migration.
D. Use the largest DB system shape to speed up the import.

Answer: B

Explanation:
To migrate an on-premises MySQL database to a MySQL DB system on OCI with the least amount of application downtime,use inbound replication to synchronize the MySQL database transactions to the DB system(Answer C).
* Inbound Replication: This method involves setting up replication from your on-premises MySQL database to the MySQL DB system in OCI. This ensures that all changes and transactions are continuously replicated, keeping the DB system up to date with minimal downtime.
* Steps to Implement:
* Set up the MySQL DB system in OCI.
* Configure the on-premises MySQL database as the master and the OCI DB system as the slave.
* Start the replication process to keep the DB system synchronized with the on-premises database.
* When ready, switch the application to the DB system with minimal downtime as the data is already synchronized.

* Incorrect format. The username should come before the password in the URL.
C:mysqlsh mysql://admin:[email protected]
* Correct format. This is a valid way to connect using a URL-like format whereadminis the username,MySQL8.0is the password, and10.0.1.221is the host.
D:mysqlsh -h10.0.1.221 -uadmin -pMySQL8.0
* Correct format. This is a valid way to connect using flags, with no spaces between the flags and their values.
E:mysqlsh -host 10.0.1.221 -user admin -password MySQL8.0
