Oracle Database 12c: RAC Administration — Question 55

Which two statements are true about Flex ASM in a Flex Cluster?

Answer options

• A. Oracle databases from releases older than 12c cannot use Flex ASM.
• B. ACFS may only be configured on a hub node running an ASM instance.
• C. Instances of ASM-based databases on hosts that have no ASM instance running, require Flex ASM.
• D. Flex ASM requires that I/Os requests be sent through an ASM Proxy Instance, regardless of database and ASM instance placement in a cluster.
• E. Hub nodes with connections from multiple leaf nodes must run an ASM instance.

Correct answer: A, C

Explanation

Statement A is correct because Flex ASM is not compatible with Oracle databases from versions older than 12c. Statement C is also true since ASM-based databases require Flex ASM when there is no ASM instance running on the host. The other options are incorrect as they either misstate the requirements for ACFS or the functionality of Flex ASM in a cluster environment.
