Question: 1/50
Your team is designing a highly available Oracle database deployment on OCI for a mission-critical application. The application requires automatic failover within a region and minimal data loss without managing OS-level clustering. Which approach best meets this requirement?
Deploy Oracle Database on a single VM DB System and rely on application retry logic
Use Oracle Data Guard with a standby database in the same region and enable Fast-Start Failover
Use manual RMAN backups and restore to a new system during an outage
Deploy two separate databases and use application-level dual writes
