You administer a Microsoft SQL Server 2012 server that hosts a transactional database
and a reporting database.
The transactional database is updated through a webapplication 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:
The differential backup of the reporting database fails.
Then, the reporting database fails at 14:00 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, and restore the latest differential backup. Then, restore
the latest log backup.
B.
Perform a point-in-time restore. Restore the latest full backup.
C.
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.
D.
Restore the latest full backup. Then, restore thelatest differential backup.
E.
Restore the latest full backup. Then, restore each differential backup taken before the
time of failure from the most recent full backup.
F.
Perform a page restore.
G.
Perform a partial restore.
H.
Restore the latest full backup.
Explanation:
Original answer is H… but I don’t particularly like any…
restore full on reporting and run update again
or use transactional full and 2 O’clock differential from Transaction db to restore the reporting db.
I’m going for something missing from question or answer
Why wouldn’t the answer be D?
have the same question as Brian.. why not D?
Since the reporting differential at 13:00 fails, the most recent backup we have is the full backup at 01:00. I don’t think it would be D, because there is no differential that can be restored after the 01:00 backup was taken. Given our limited answers, I think H is the way to go.
H
Restore the latest full backup.
I believe the answer should be D, since the database fails at 14:00 hours and the lastest full backup was taken at 1:00 am , if you restore the full database backup, you still have to restore the differential backup at 13:00 hr
what is the correct answer?
Full restore, option H is the right answer as the latest Diff Backup is corrupted.
Correct answer is D. The differential b/up performed on REPORTING db at 13:00HRS (1:00pm) failed, and this preceded the DB’s failure at 14:00HRS (2:00pm). Prior to its failure however, a FULL b/up of the REPORTING db was performed at 01:00HRS (1:00am); this is the only valid b/up to restore to the REPORTING database.
However, the TRANSACTIONAL db did not fail, and both full and differential backups were performed on it (as scheduled). After restoring the 01:00HRS (1:00am) backup to the REPORTING db, we should be applying the most recent differential backup available from the TRANSACTIONAL db (performed at 11:00HRS (11:00am)). This is the latest differential b/up performed on TRANSACIONAL db prior to failure of REPORTING db.
**Logic: 01:00HRS preceeds 11:00HRS; so, if failure occurs at 13:00HRS, there’s a differential backup available from TRANSACTIONAL at 11:00HRS.
Can you really restore a differential from the transactional on the reporting? The differential on the transaction will be from a backup that is in a different state than the backup on the reporting because different databases are different. Even if you could use a differential from, the transactional, the transfer from transactional to reporting is 30 minutes after the backup. Then a backup is taken on the reporting. If there are transaction between 0:00 and :30 on the transactional, that will be reflected in the full backup on the reporting and the differential in the transactional and would be double counted. The real life solution is to take a snapshot of the transactional and restore it so you don’t have to do any of this theoretical nonsense. I think it’s H

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 23:32 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. Perform a page restore.
B. Perform a partial restore.
C. Perform a point-in-time restore.
D. Restore the latest full backup.
E. Restore the latest full backup. Then, restore the latest differential backup.
F. Restore the latest full backup, and restore the latest differential backup. Then, restore the latest log backup.
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 each differential backup taken before the time of failure from the most recent full backup.
Answer: E
Explanation:
To recover the database, you must restore the latest full backup and then restore the latest differential backup.
Incorrect answers:
A: A page restore is used to repair isolated damaged pages. It is faster than a file restore id only a few individual pages are damaged.
B: Partial restores allow a database that contains multiple filegroups to be restored and recovered in stages.
It works with all recovery models, but is more flexible for the full and bulk-logged models than for the simple model.
C: Point in time restores are not supported for the simple backup model as log files are not part of the backup.
D: The latest full backup was performed at 01:00 hours, 22 hours and 32 minutes before the hard disk failure. A differential backup was made at 13:00 hours, 10 hours and 32 minutes before the hard disk failure. A differential backup contains data that has been added or updated since the last full backup and should be restored to minimize data loss.
F, G: There is not log backup in the simple backup model.
H: Only the latest differential backup needs to be restored.

Explanation:
The general process for creating and using an audit is as follows.
1. Create an audit and define the target.
2. Create either a server audit specification or database audit specification that maps to the audit. Enable the audit specification.
3. Enable the audit.
4. Read the audit events by using the Windows Event Viewer, Log File Viewer, or the fn_get_audit_file function.
NEW QUESTION 200
You administer a Microsoft SQL Server 2012 Enterprise Edition server that uses 64 cores. You discover performance issues when complex calculations are performed on large amounts of data under heavy system load. You need to limit the number of cores that process the calculations. What should you configure?
A. Max worker threads
B. Processor affinity
C. I/O affinity
D. Lightweight pooling
Answer: B
Explanation:
To carry out multitasking, the operating system sometimes moves process threads among different processors. This is efficient from an operating system point of view, but can reduce SQL Server performance under heavy system loads, as each processor cache is repeatedly reloaded with data. Assigning processors to specific threads can improve performance under these conditions by eliminating processor reloads; such an association between a thread and a processor is called processor affinity.
