Q32. Which two statements are true about the UNDROP clause of the ALTER DISKGROUP statement?
A. It cancels pending drops of disks dropped using the DROP DISKGROUP command.
B. A disk cannot be undropped as a result of a drop diskgroup.

C. In a RAC database, there is no LMD0 process if only one instance is running.
D. Global Enqueues and Instance Locks replace latches completely in RAC database isntances.

C. Only one ADVM volume can be created in an ASM disk group.
D. ADVM extends ASM by providing a device driver interface to storage backed by an ASM disk group.
E. File systems contained in ADVM volumes may only contain database files.
Each volume is individually named and may be configured for a single file system. Reference: https://docs.oracle.com/database/121/OSTMG/GUID-B7A61F3B-C22A-4021-A846F5EA749E79FF.htm#OSTMG32000 (See Note and the third para from the top.)

B. Their names can be seen in dict when connected to an ASM instance.
C. Their names can be seen in v$fixed_table when connected to an instance of any type that is started.
D. They exist in both in ASM and RDBSM instances, but they can display different outputs depending on theinstance type.

Q38. Which three statements are true regarding ACFS snapshots in Oracle 12c ASM?
A. They are contained in a directory on the same volume as their parent file system.
B. All ACFS snapshot operations for all filesystem are serialized clusterwide.
C. You can create a snapshot from an existing snapshot.
D. They can be administered using ASMCMD.
E. They can only be accessed when the file system is mounted.
F. They are always point-in-time copies of the parent file system.
All Oracle ACFS snapshot operations are serialized clusterwide in the kernel. you chose to create a snapshot image on an existing snapshot group, select a snapshot group from the existing snapshot group table (make sure you select a snapshot group that has not reached its maximum limit of snapshot images).
Before you can access the files on a file system, you need to mount the file system.
