I am not sure about
C The OCR is backed up by default to a cluster file system location.
the default location is /cdata/ actually is file system, but thinking a bit I guess it could be storage on ACFS partition… therefore
I will go to the JAG answer…
Correct A,B,D ( but for me C is also true, but not specific)
Correct: A,B,D
Wrong C: /cdata is in LFS. GI binaries cannot be placed at CFS
Wrong E: Automatic backups are not supported for the OLR.
Wrong F: The default backup location for the OLR is in the path grid_home/cdata/host_name. To change the OLR backup location: ocrconfig -local -backuploc new_olr_backup_path
ABD
