A disaster recovery test is being performed, using backups from a production system. The backup
process is as follows:
Full system save, using GO SAVE Option 21, for weekly backup
SAVCHGOBJ LIB(*ALL) is used for daily library backup, in addition to DLO and IFS saves
The disaster recovery test is at the point where libraries are ready to be restored
Which pair of actions will restore the libraries to the most recent save point, in the minimum
amount of time?

A.
Use RSTLIB(*NONSYS) to restore all libraries and object from the SAVE 21 weekly save. For
each daily tape, run a RSTLIB for each library saved by SAVCHGOBJ.

B.
Use RSTLIB(*NONSYS) to restore all libraries and object from the SAVE 21 weekly save. Then
run a RSTOBJ for each library saved by SAVCHGOBJ on the most recent daily tape.

C.
Run RSTOBJ for each library saved by SAVCHGOBJ on the most recent daily tape.
Then run RSTLIB(*NONSYS) OPTION(*NEW) to restore the remaining libraries and objects from
the SAVE 21 weekly save.

D.
For each daily tape, run RSTOBJ for each library saved by SAVCHGOBJ on the daily tapes.
Then run RSTOBJ(*NONSYS) OPTION(*NEW) to restore the remaining libraries and objects from
the SAVE 21 weekly save.
