C) The OUI does not support a RAC installation if the Standard Edition is chosen from the Installation Type page.
D) The Oracle Universal Installer (OUI) can detect the cluster hardware and allow the user to install the software on the local node or choose all nodes to install the software.

3. Which two tools will prompt you for the possible creation of ASM instances in a RAC environment? (Choose two.)

A) OUI
B) ASMCMD
C) SRVCTL
D) VIPCA
E) DBCA

5. View the Exhibit.
You are required to support your Oracle RAC configuration using ASM and RAID technology. You plan to discuss the storage configuration with the storage technology team. They have proposed a configuration as shown in the exhibit with a separate set of LUNs for the data disk group and the flash recovery area disk group and a 500 KB stripe size in line with other non-Oracle LUNs. The Data disk group has four250G LUNs and the FRA disk group has four500G LUNS, both of which are mirrored.

A) Retention policies that require backups to be kept for long time periods may cause wasted space due to large allocation units.
B) The LUNs are not aligned with ASM Allocation Units, which may lead to I/O bottlenecks.
C) I/O to the flash recovery area disk group for backups may cause performance issues when full table scans are occurring during batch workloads.
D) Index Range Scans would cause I/O to many different physical disks.
