Oracle Database Administration 2019 Certified Professional — Question 45

Which three statements are true about the Oracle Clusterware 19c Flex Cluster architecture? (Choose three.)

Answer options

• A. Each hub node must be connected to storage shared across all hub nodes.
• B. Each leaf node must be connected to storage shared across all cluster nodes.
• C. Each leaf node must be connected to storage shared across all leaf nodes.
• D. Leaf nodes require direct access to the voting disks.
• E. Hub nodes require direct access to the OCR file.
• F. Hub nodes require direct access to the voting disks.

Correct answer: A, E, F

Explanation

The correct answers A, E, and F are true because hub nodes in a Flex Cluster architecture need to have shared storage access for proper operation, including direct access to the OCR file and voting disks. Options B, C, and D are incorrect as leaf nodes do not require shared storage across all cluster nodes, nor do they need direct access to voting disks.
