Which two actions guarantee that time is synchronized properly on all nodes in a cluster after installing Oracle Grid Infrastructure 12c? (Choose two.)

• A.Deactivate network time protocol (NTP) on all cluster nodes; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in active mode when the clusterware is started.
• B.Configure network time protocol (NT P) on all cluster nodes; Oracle Cluster Time Synchronization Service (CTSSD) will then start automatically in observer mode when the clusterware is started.
• C.Configure network time protocol (NTP) on all cluster nodes, and then start the Oracle Cluster Time Synchronization Service (CTSSD) in active mode on all cluster nodes.
• D.If network time protocol (NT P) is not configured properly on all cluster nodes, then Oracle Cluster Time Synchronization Service (CTSSD) will start automatically in active mode when the clusterwareis started.
• E.If network time protocol (NTP) time servers are unreachable on any cluster node, then Oracle CTSSD Time Synchronization Service (CTSSD) will start automatically in active mode when the clusterware is started.

• C.The OLR can be backed up using ocrconfig.
• D.The OLR is backed up by default to a cluster file system location.

• 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.Flex ASM requires that I/Os requests be sent through an ASM Proxy Instance, regardless of database and ASM instance placement in a cluster.
• D.Hub nodes with connections from multiple leaf nodes must run an ASM instance.
• E.Instances of ASM-based databases on hosts that have no ASM instance running, require Flex ASM.
