Which two conditions are required by the ASM fast mirror resynchronization to track block changes for a set period of time before dropping the disk from the disk group?
A.
Redundancy is normal or high.
B.
compatibility.rdbms is set to a value of at least 11.1.
C.
disk_repair_time is set to a nondefault value.
D.
block_change_tracking IS enabled.
E.
db_block_checking is enabled.
F.
resumable_timeout is set to a nondefault value.
A & B are correct.
C & E are the correct answers
sorry, not correct.
A & B are correct. By default, disk_repair_time is set to non-zero value and block_change_tracking has nothing to do with this functionality
A & B are correct.

As mentioned above we need to use ASM redundancy (not external redundancy).
ASM disk group attributes COMPATIBLE.RDBMS and COMPATIBLE.ASM must be set to the minimum software release of 11.1.
Setting up DISK_REPAIR_TIME is optional. It has a default value of 3.6h
A,B is correct answer.

To use this feature, the disk group compatibility attributes must be set to 11.1 or higher.
