Oracle Database 10g R2: Administering RAC Sample Questions:

1. You are migrating a single-instance Oracle database to RAC. The data files and Flash Recovery Area would be migrated to ASM using the RMAN commands BACKUP AS COPY DATABASE and BACKUP RECOVERY AREA, and stored in an ASM diskgroups called +DB_DG and +FR_DG. The DB_CREATE_FILE_DEST parameter would be set to +DB_DG and the DB_RECOVERY_FILE_DEST parameter would be set to +FR_DG.
What are the three best options for the location of your archivelogs so that they may be used properly for recovery without DBA intervention? (Choose three.)

A) Cluster File System with each instance writing to a separate location as long as they are in directories under the same mount point.
B) Cluster File System with each instance writing to a shared location.
C) Local File System with each instance writing to a local location provided that NFS read mount points are created to all other nodes with instances of the database.
D) ASM diskgroup +DB_DG as specified for the Database Area provided that the ASM diskgroup is mounted on all ASM instances.
E) ASM diskgroup +FR_DG as specified for the Flash Recovery Area provided that the ASM diskgroup is mounted on all ASM instances.
F) Local File System with each instance writing to a local location provided that the path names are identical on all nodes.
