第17题：

A system administrator has backed up the datavg volume group using the savevg command. There are several raw logical volumes and some unmounted jfs filesystems in datavg. Which of the following statements is true about this backup?（）

• A、The volume group and all logical volumes will be recreated. All raw and jfs filesystms will be backed up and restored.
