You are working as a DBA in a RAC environment that is available for testing. The RAC environment has all the database files stored in the OCFS file system. You plan to install ASM and move all the database files to ASM to achieve better performance. During the installation, you selected redundancy level as normal for the disk group being added. What is the reason for selecting this redundancy level?
You want to use hardware mirroring.
You do not want to have any mirroring in the disk group.
You have two failure groups defined, so you want to use two-way mirroring.
You have three failure groups defined, so you want to use three-way mirroring.
