Oracle Database Administration 2019 Certified Professional — Question 71

Which three are benefits of using RAC One Node in Oracle 19c? (Choose three.)

Answer options

• A. Multiple instances of the same database on a single node to protect against instance failure
• B. Ability to perform rolling patches
• C. Automatic failover for high availability
• D. Online conversion from non-RAC databases to RAC One Node databases
• E. Online conversion from RAC One Node databases to multi-instance RAC databases
• F. Load balancing of services within a single instance

Correct answer: B, D, E

Explanation

The correct answers are B, D, and E because RAC One Node allows for rolling patches, facilitates the online conversion from non-RAC to RAC One Node databases, and also supports the online conversion from RAC One Node to multi-instance RAC databases. Options A and C are not benefits of RAC One Node, as it does not involve multiple instances on a single node for instance failure protection or automatic failover capabilities.
