A : Use replication to roll out changes to higher environments.

B : Use backup and restore to roll out changes to higher environments.

C : Use Liquibase to roll out changes to higher environments.

D : Manually capture detailed DBA audit logs when changes are rolled out to higher environments.

Answer: C

Question 3

Your application follows a microservices architecture and uses a single large Cloud SQL instance, which is starting to have performance issues as your application grows. in the Cloud Monitoring dashboard, the CPU utilization looks normal You want to follow Google-recommended practices to resolve and prevent these performance issues while avoiding any major refactoring. What should you do?

Question 4

Your company is migrating the existing infrastructure for a highly transactional application to Google Cloud. You have several databases in a MySQL database instance and need to decide how to transfer the data to Cloud SQL. You need to minimize the downtime for the migration of your 500 GB instance. What should you do?

A : Create a Cloud SQL for MySQL instance for your databases, and configure Datastream to stream yourdatabase changes to Cloud SQL.Select the Backfill historical data check box on your stream configuration to initiate Datastream tobackfill any data that is out of sync between the source and destination.Delete your stream when all changes are moved to Cloud SQL for MySQL, and update your applicationto use the new instance.

B : Create migration job using Database Migration Service.Set the migration job type to Continuous, and allow the databases to complete the full dump phase andstart sending data in change data capture (CDC) mode.Wait for the replication delay to minimize, initiate a promotion of the new Cloud SQL instance, andwait for the migration job to complete.Update your application connections to the new instance.

C : Create migration job using Database Migration Service.Set the migration job type to One-time, and perform this migration during a maintenance window.Stop all write workloads to the source database and initiate the dump. Wait for the dump to be loadedinto the Cloud SQL destination database and the destination database to be promoted to the primarydatabase.Update your application connections to the new instance.

D : Use the mysqldump utility to manually initiate a backup of MySQL during the application maintenancewindow.Move the files to Cloud Storage, and import each database into your Cloud SQL instance.Continue to dump each database until all the databases are migrated.Update your application connections to the new instance.

Answer: C
