a. performs a level 0 backup once per month.
b. performs a level 2 dump one day per week
c. performs a level 5 dump every day that neither a level 0 nor a level 2 dump is performed.
In the worst case, how many restores would you have to perform to recover a file that was dumped using the preceding schedule?
