問題文
A DBA wants files of one type in a disk group to be striped and mirrored differently from the rest. Which statement describes how templates work?
選択肢
- Templates are read solely at the moment a disk group is created, so a template that is added later has no effect on the files that are created in that disk group afterwards.
- Each disk group has a default template for every file type, and a template can be customized so that a file created with it gets the striping and the mirroring that the template names.
- Templates apply to disks rather than to files, so a template names the failure group that a disk joins and the region of the disk that the extents of a mirrored file may be placed in.
- Each disk group has one template that applies to all of the file types, and the striping and the mirroring of an individual file can solely be changed by moving that file into another disk group afterwards.
