Actual exam question from Oracle's 1z0-060
Question #: 82
Topic #: 1
[All 1z0-060 Questions]

You support Oracle Database 12c Oracle Database 11g, and Oracle Database log on the same server.
All databases of all versions use Automatic Storage Management (ASM).
Which three statements are true about the ASM disk group compatibility attributes that are set for a disk group?

  • A. The ASM compatibility attribute controls the format of the disk group metadata.
  • B. RDBMS compatibility together with the database version determines whether a database Instance can mount the ASM disk group.
  • C. The RDBMS compatibility setting allows only databases set to the same version as the compatibility value, to mount the ASM disk group.
  • D. The ASM compatibility attribute determines some of the ASM features that may be used by the Oracle disk group.
  • E. The ADVM compatibility attribute determines the ACFS features that may be used by the Oracle 10 g database.

Suggested Answer: ABD 🗳️
A, D: The value for the disk group COMPATIBLE.ASM attribute determines the minimum software version for an Oracle ASM instance that can use the disk group.
This setting also affects the format of the data structures for the Oracle ASM metadata on the disk.
B: The value for the disk group COMPATIBLE.RDBMS attribute determines the minimum COMPATIBLE database initialization parameter setting for any database instance that is allowed to use the disk group. Before advancing the COMPATIBLE.RDBMS attribute, ensure that the values for the COMPATIBLE initialization parameter for all of the databases that access the disk group are set to at least the value of the new setting for COMPATIBLE.RDBMS.
For example, if the COMPATIBLE initialization parameters of the databases are set to either 11.1 or 11.2, then COMPATIBLE.RDBMS can be set to any value between 10.1 and 11.1 inclusively.
Incorrect Answers:
E:
/The value for the disk group COMPATIBLE.ADVM attribute determines whether the disk group can contain Oracle ASM volumes. The value must be set to 11.2 or higher. Before setting this attribute, the COMPATIBLE.ASM value must be 11.2 or higher. Also, the Oracle ADVM volume drivers must be loaded in the supported environment.
/ You can create an Oracle ASM Dynamic Volume Manager (Oracle ADVM) volume in a disk group. The volume device associated with the dynamic volume can then be used to host an Oracle ACFS file system.
The compatibility parameters COMPATIBLE.ASM and COMPATIBLE.ADVM must be set to 11.2 or higher for the disk group.
Note:
* The disk group attributes that determine compatibility are COMPATIBLE.ASM, COMPATIBLE.RDBMS. and COMPATIBLE.ADVM. The COMPATIBLE.ASM and
COMPATIBLE.RDBMS attribute settings determine the minimum Oracle Database software version numbers that a system can use for Oracle ASM and the database instance types respectively. For example, if the Oracle ASM compatibility setting is 11.2, and RDBMS compatibility is set to 11.1, then the Oracle ASM software version must be at least 11.2, and the Oracle Database client software version must be at least 11.1. The COMPATIBLE.ADVM attribute determines whether the Oracle ASM Dynamic Volume Manager feature can create a volume in a disk group.
