Exam 1z0-078 topic 1 question 43 discussion

D: "ASM disk groups used for voting files and OCR files require a quorum failgroup." This statement is correct. Disk groups that contain Oracle Clusterware files (OCR and voting files) have a higher minimum number of failure groups than other disk groups because the voting files are stored in quorum failure groups. A quorum failure group ensures that a quorum of the specified failure groups are available and is used to determine if the disk group can be mounted if there is a loss of one or more failure groups. E: The Installer permits the creation of a disk group for use by the voting disks and OCR file is true. The Oracle Universal Installer can be used to install Oracle Clusterware, which can put the Oracle Cluster Registry (OCR) and the voting files on Oracle Automatic Storage Management (Oracle ASM). The installer provides the option to automatically mirror OCR. Also, the Grid Infrastructure Management Repository can be created in its own disk group during installation of Oracle Grid Infrastructure.

B but NOT for ASM Instance. ASM Instance can't be in archivelog mode, so recovery area isn't needed. I think this answer is badly transcribed. A database can use ASM or shared storage independently C incorrect, ASM diskgroup can be created for the first time after ASM startup D quorum failgroup is required for voting diskgroup with normal or high redundancy

A. Incorrect: Databases can use other storage options independently of ASM being used for Clusterware files. B. Correct: The Installer allows creating a disk group for the Recovery Area during installation. C. Incorrect: ASM instances can still be started without specifying ASM disk groups during installation. D. Incorrect: ASM requires redundancy but does not specifically require a "quorum failgroup." E. Correct: The Installer allows creating a disk group for voting disks and OCR files during installation.
