Oracle Database Administration 2019 Certified Professional — Question 89

Which two statements are true about Oracle Clustered ASM performance? (Choose two.)

Answer options

• A. Data files, redo logs, and RMAN backup pieces must be stored in different ASM disk groups for optimal performance.
• B. All ASM Disks belonging to a disk group should be of the same size for optimal performance.
• C. Hardware-based mirroring combined with ASM mirroring guarantees optimal performance.
• D. All ASM Disks belonging to a disk group should have the same hardware specifications and storage attributes for optimal performance.
• E. To improve performance a database must have two disk groups; one for data and one for the fast recovery area.

Correct answer: B, D

Explanation

Option B is correct as having ASM Disks of the same size allows for efficient data distribution and performance optimization. Option D is also correct because uniform hardware specifications ensure consistent performance across the disks. Options A, C, and E are incorrect as they do not accurately reflect the best practices for ASM performance management.
