Oracle Database 12c: Installation and Administration — Question 122

Which two statements are true about variable extent size support for large ASM files? (Choose two.)

Answer options

• A. The metadata used to track extents in SGA is reduced.
• B. Rebalance operations are completed faster than with a fixed extent size
• C. An ASM Instance automatically allocates an appropriate extent size.
• D. Resync operations are completed faster when a disk comes online after being taken offline.
• E. Performance improves in a stretch cluster configuration by reading from a local copy of an extent.

Correct answer: A, C

Explanation

Answer A is correct as variable extent sizes reduce the amount of metadata required in the SGA, optimizing resource usage. Answer C is also correct because ASM Instances are designed to allocate the most suitable extent size automatically. Options B, D, and E do not accurately reflect the benefits of variable extent size support and are therefore incorrect.
