For the successful execution of the second command, the disk group compatibility attribute for ADVM must be set to 12.1 or higher. This is necessary for the use of the parent snapshot feature, allowing one snapshot to be created from another. If the ADVM compatibility is less than 12.1, creation from an existing snapshot is not permitted.
Correct answer is A. Creation from an existing snapshot is not permitted if there are: Any snapshots present in the file system that were created with the ADVM compatibility set to less than 12.1
A. Correct: ADVM compatibility must be 12.1 or higher for the parent snapshot feature. B. Incorrect: The parent snapshot can be read/write; it doesn't have to be read-only. C. Incorrect: High redundancy is not required for creating snapshots. D. Incorrect: The parent snapshot can be either read/write or read-only.
B - wrong - the parent snap can be RW, but it has to be created on compatible >=12.1 Creation from an existing snapshot is not permitted if there are: Any snapshots present in the file system that were created with the ADVM compatibility set to less than 12.1 https://docs.oracle.com/en/database/oracle/oracle-database/21/acfsg/acfs-commands-snapshots.html#GUID-A1E4A4B5-CD16-4ADC-817D-4CD7D2DA12DF
