Which two statements are true regarding the configuration of ASM disk groups when installing Oracle Grid Infrastructure 12c?
A. The installer permits the creation of a disk group for use by the voting disks and OCR file.
B. If no ASM disk groups are specified during installation, then ASM instances are not started after the installation completes on any cluster node.
C. The installer permits the creation of a disk group to be used for the Recovery Area for the ASM instance.
D. If ASM disk groups are configured for the Clusterware files, then ASM must be used for all databases on the cluster.
E. ASM disk groups used for voting files and OCR files require a quorum failgroup.
Correct Answer: AB
Explanation/Reference:
Explanation:
You can store Oracle Cluster Registry (OCR) and voting files in Oracle ASM disk groups.
Incorrect Answers:
D: If you install Oracle Database or Oracle RAC after you install Oracle Grid Infrastructure, then you can either use the same disk group for database files, OCR, and voting files, or you can use different disk groups. If you create multiple disk groups before installing Oracle RAC or before creating a database, then you can do one of the following:
Place the data files in the same disk group as the Oracle Clusterware files.
Use the same Oracle ASM disk group for data files and recovery files.
Use different disk groups for each file type.
