Oracle Database Administration 2019 Certified Professional — Question 20

Which two statements are true about initialization parameters for Clustered ASM instances? (Choose two.)

Answer options

• A. The maximum value of ASM_POWER_LIMIT is 1024.
• B. The default value of INSTANCE_TYPE is ASM.
• C. A change to ASM_DISKSTRING requires a restart of all ASM instances for the change to take effect.
• D. The ASM_DISKGOUPS parameter is optional.
• E. ASM_POWER_LIMIT controls the number of RDBMS instances that can access a disk group while it is being rebalanced.

Correct answer: A, D

Explanation

Option A is correct because the maximum value of ASM_POWER_LIMIT is indeed 1024. Option D is also correct as ASM_DISKGROUPS is optional. The other options are incorrect because B is wrong since INSTANCE_TYPE defaults to ASM, C is false because changes to ASM_DISKSTRING do not require a restart of all ASM instances, and E is inaccurate as ASM_POWER_LIMIT does not control RDBMS access during rebalancing.
