Which three are benefits of using RAC One Node in Oracle 12c?
A.
automatic failover for high availability
B.
ability to perform rolling patches
C.
online conversion from RAC One Node databases to multi-instance RAC databases
D.
load-balancing of services within a single instance
E.
online-conversion from non-RAC databases to RAC One Node databases
F.
multiple instances of the same database on a single node to protect against instance failure
Explanation:
Oracle Real Application Clusters One Node is a single instance of an Oracle Real Application Clusters-enabled database running on one node in a cluster. It lets
you consolidate multiple databases onto a single cluster and thereby adds to the flexibility that Oracle offers for database consolidation while reducing management
overhead by providing a standard deployment for highly available Oracle Database editions.
Overview
Failover cluster protection for unplanned downtime
Online Database Relocation for workload management
Online database patching to reduce planned downtime
(C) Online upgrade to Oracle RAC for full scalability
Benefits
(F) Protection from unplanned database or system failures
(B) Rolling upgrades and patches for your OS and database
Standard management for highly available Oracle Databases
Online Databases Relocation for database virtualization

Hello
Correct answers should be A,B and C
F is incorrect, RAC One node will not run multiple instances of the same db on the same node. It will will failover to another server in the cluster should a server, instance or a related and monitored component on this server fail (A).
Hi jk
You are right
Regards
Oracle RAC One Node is supported on all platforms on which Oracle RAC is certified. Oracle RAC One Node is certified on Oracle Virtual Machine (Oracle VM). Oracle RAC One Node provides the following benefits:
• Always available single-instance database services
• Built-in “cluster failover for high availability”
• Live migration of instances across servers
• Online “rolling patches” and rolling upgrades for single-instance databases
• “Online upgrade from single-instance to multi-instance Oracle RAC”
• Better consolidation for database servers
• Enhanced server virtualization
• Lower-cost development and test platform for full Oracle RAC
So the answer is A, B, C
A,B,C I agree
