Which three statements are true about the Oracle Clusterware 19c Flex Cluster architecture? (Choose three.)
Which three statements are true about the Oracle Clusterware 19c Flex Cluster architecture? (Choose three.)
In the Oracle Clusterware 19c Flex Cluster architecture, each hub node must indeed be connected to storage shared across all hub nodes, ensuring data consistency and synchronization (A). Hub nodes also require direct access to the Oracle Cluster Registry (OCR) file, which contains information critical for the cluster's operation (E). Additionally, hub nodes need direct access to the voting disks, which are used to monitor the health and status of all nodes within the cluster, helping in quorum decisions (F).
A. Correct - Hub nodes need shared storage accessible to all hub nodes. B. Incorrect - Leaf nodes do not need to be connected to storage shared across all cluster nodes. C. Incorrect - Leaf nodes do not require shared storage with other leaf nodes. D. Incorrect - Leaf nodes do not need direct access to the voting disks. E. Correct - Hub nodes require direct access to the OCR file. F. Correct - Hub nodes require direct access to the voting disks.
