Demo Questions
Question 1
You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a storage area network (SAN).
The financial database has the following characteristics:
- A data file of 2 terabytes is located on a dedicated LUN (drive D). A transaction log of 10 GB is located on a dedicated LUN (drive E).
- Drive D has 1 terabyte of free disk space.
- Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15 hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of data to the database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You need to ensure that the minimum amount of data is lost.
Which recovery model should the database use?
- NORECOVERY
- FULL
- NO_CHECKSUM
- CHECKSUM
- Differential
- BULK_LOGGED
- STANDBY
- RESTART
- SKIP
- Transaction log
- DBO ONLY
- COPY_ONLY
- SIMPLE
- CONTINUE AFTER ERROR
Correct answer: B
Explanation:
The full recovery model requires log backups. No work is lost due to a lost or damaged data file. Can recover to a specific point in time, assuming that your backups are complete up to that point in time. Incorrect Answers:F: The bulk logged recovery model can recover to the end of any backup. Point-in-time recovery is not supported.M: The simple recovery model can recover only to the end of a backup.References: https://docs.microsoft.com/en-us/sql/relational-databases/backup-restore/recovery-models-sql-server The full recovery model requires log backups.

- A data file of 2 terabytes is located on a dedicated LUN (drive D). A transaction log of 10 GB is located on a dedicated LUN (drive E).
- Drive D has 1 terabyte of free disk space.

A full database backup is performed every Sunday at 10:00 hours. Backup operations will be performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You need to ensure that the backup size is as small as possible.
Which backup should you perform every two hours?
- NORECOVERY
- FULL
- NO_CHECKSUM
- CHECKSUM
- Differential
- BULK_LOGGED
- STANDBY
- RESTART
- SKIP
- Transaction log
- DBO ONLY
- COPY_ONLY
- SIMPLE
- CONTINUE AFTER ERROR
Correct answer: J
Explanation:
Minimally, you must have created at least one full backup before you can create any log backups. After that, the transaction log can be backed up at any time unless the log is already being backed up.

Question 3
You administer a Microsoft SQL Server 2012 instance named SQL2012 that hosts an OLTP database of 1 terabyte in size.
The database is modified by users only from Monday through Friday from 09:00 hours to 17:00 hours. Users modify more than 30 percent of the data in the database during the week.
Backups are performed as shown in the following schedule:
The Finance department plans to execute a batch process every Saturday at 09:00 hours. This batch process will take a maximum of 8 hours to complete.
The batch process will update three tables that are 10 GB in size. The batch process will update these tables multiple times.
When the batch process completes, the Finance department runs a report to find out whether the batch process has completed correctly.
You need to ensure that if the Finance department disapproves the batch process, the batch operation can be rolled back in the minimum amount of time.
What should you do on Saturday?
- Perform a differential backup at 08:59 hours.
- Record the LSN of the transaction log at 08:59 hours. Perform a transaction log backup at 17:01 hours.
- Create a database snapshot at 08:59 hours.
- Record the LSN of the transaction log at 08:59 hours. Perform a transaction log backup at 08:59 hours.
- Create a marked transaction in the transaction log at 08:59 hours. Perform a transaction log backup at 17:01 hours.
- Create a marked transaction in the transaction log at 08:59 hours. Perform a transaction log backup at 08:59 hours.
