You administer a Microsoft SQL Server 2012 server that hosts a transactional database and a
reporting database. The transactional database is updated through a web application and is
operational throughout the day. The reporting database is only updated from the transactional
database.
The recovery model and backup schedule are configured as shown in the following table:
One of the hard disk drives that stores the reporting database fails at 16:40 hours.
You need to ensure that the reporting database is restored. You also need to ensure that data loss is
minimal.
What should you do?
A.
Restore the latest full backup. Then, restore each differential backup taken before the time of
failure from the most recent full backup.
B.
Perform a partial restore.
C.
Restore the latest full backup, and restore the latest differential backup. Then, restore the latest
log backup.
D.
Perform a point-in-time restore.
E.
Restore the latest full backup.
F.
Perform a page restore.
G.
Restore the latest full backup, and restore the latest differential backup. Then, restore each log
backup taken before the time of failure from the most recent differential backup.
H.
Restore the latest full backup. Then, restore the latest differential backup.
H.Restore the latest full backup. Then, restore the latest differential backup.
This is the correct answer. You will restore the full from 01:00 and the diff from 13:00. The database is in SINGLE so there’s no log to restore.

why not A ?

Not sure but ‘each’ would suggest more than one differential backup but the backup schedule displayed would result in there only being one possible differential backup. A trick question perhaps.

Does this mean that if the answer is H, the next data update will be at 00:30? Seems like more than minimal data loss…
