You can store Oracle Cluster Registry (OCR) and voting files in Oracle ASM disk groups. d 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.
