Google Cloud Professional Cloud Database Engineer — Question 119

Your company is migrating all legacy applications to Google Cloud. All on-premises applications are using legacy Oracle 12c databases with Oracle Real Application Cluster (RAC) for high availability (HA) and Oracle Data Guard for disaster recovery. You need a solution that requires minimal code changes, provides the same high availability you have today on-premises, and supports a low latency network for migrated legacy applications. What should you do?

Answer options

• A. Migrate the databases to Cloud Spanner.
• B. Migrate the databases to Cloud SQL, and enable a standby database.
• C. Migrate the databases to Compute Engine using regional persistent disks.
• D. Migrate the databases to Bare Metal Solution for Oracle.

Correct answer: D

Explanation

The correct answer is D because Bare Metal Solution for Oracle provides the most seamless transition for Oracle databases with minimal code changes, maintaining high availability and performance. Options A and B do not support Oracle RAC and Data Guard, while C lacks the necessary features for high availability and disaster recovery that the organization currently has.
