Which method should be used to convert a single-instance Oracle 19c Database to a RAC Database?
A.
Using the rconfig utility to migrate the database to shared storage and then using DBCA to start one or more RAC database instances on the cluster
B.
Using DBCA to migrate the database to shared storage and then to start one or more RAC database instances on the cluster
C.
Using the rconfig utility to create a template from the single-instance database and then using DBCA to create a RAC database on the cluster using that template
D.
Using DBCA to create a template from the single-instance database and then to create a RAC database on the cluster using that template
D: Using DBCA to create a template
This is a supported method for converting a single-instance database to RAC. DBCA automates the configuration of the control file attributes, creates the undo tablespaces and the redo logs, and creates the initialization parameter file entries for cluster-enabled environments. DBCA also configures Oracle Net Services, Oracle Clusterware resources, and the configuration for Oracle RAC database management using Oracle Enterprise Manager or the Server Control utility (SRVCTL)
D DBCA template creation and RAC conversion are part of required step for DBCA single-instance to RAC conversion

A. Incorrect:
rconfig used for template, not storage migration.
DBCA does not start RAC instances.
B. Incorrect:
DBCA does not migrate to shared storage.
Oversimplifies RAC instance startup.
C. Correct:
rconfig for template creation.
DBCA for creating RAC database from template.
D. Incorrect:
DBCA can create template but insufficient for RAC setup.
Ignores necessary RAC configuration steps.
Looks like D
