A database backup schedule consists of weekly full backups performed on Saturday at 12:00 a.m. and daily differential backups also performed at 12:00 a.m. If the database is restored on Tuesday afternoon, which of the following is the number of individual backups that would need to be applied to complete the database recovery?
A.
1
B.
2

Easy one: We have
Sat = Full
Sun = Dif
Mon = Dif
So I need:
Sat Full + Mon Dif (As monday dif also contains Sunday dif)

pay attention differential backup is difference from the full backup.
incremental backup is the difference from the last incremental backup.
then 2 is correct, you have to apply the full + the last diff backup.
