Full set: 77 questions

Answer options

A: The ACFS file system will be permanently removed from the volume.

B: The ACFS mount registry with Oracle restart is automatically deleted.

C: The disabling of volume does not destroy data in the file system. Correct answer

D: The volume can be enabled and the file system can be mounted back again to access the existing data. Correct answer

E: The ACFS file system will be permanently removed from the volume only if the file system is empty.

Correct Answer:

C. The disabling of volume does not destroy data in the file system.; D. The volume can be enabled and the file system can be mounted back again to access the existing data.

Explanation

The voldisable operation only marks the volume offline; it does not affect the on-disk contents. After reenabling the volume, the same ACFS file system can be remounted and the data accessed. No automatic deletion or file-system removal occurs.

Why Incorrect

A – voldisable does not delete the file system. B – The ACFS mount registry entry is retained; manual removal is required if desired. E – File-system removal is never automatic, regardless of contents.
