You have a SQL Server 2012 database named DB1. You have a backup device named Device1. You discover that the log file for the database is full. You need to ensure that DB1 can complete transactions. The solution must not affect the chain of log sequence numbers (LSNs). Which code segment should you execute? a) BACKUP LOG DB1 TO Device1 WITH COPY_ONLY b) BACKUP LOG DB1 TO Device1 WITH NORECOVERY c) BACKUP LOG DB1 TO Device1 WITH TRUNCATE_ONLY d) BACKUP LOG DB1 TO Device1 02. You are writing a stored procedure that will include a transaction that performs the following: - Applies a discount to the Price column of the Product table for any product that is within one month of its discontinued date - Inserts a record for each discounted product into the Specials table There is a trigger on the Product table that logs information about changes to the Price column to the PriceChanges table.

What should you do? a) Create an INSTEAD OF trigger on the view. b) Define the view by using the SCHEMABINDING option. c) Define the view by using the CHECK option. d) Materialize the view. 05. You have an index for a table in a SQL Azure database. The database is used for Online Transaction Processing (OLTP). You discover that many page splits occur when records are inserted or updated in the table. You need to minimize the number of page splits.

Which tool should you use? a) Extended Events b) Database Engine Tuning Advisor c) Data Profile Viewer d) Performance Monitor 09. You create a table using the following statement: CREATE TABLE Paintings (ID int, Title nvarchar) You populate the Paintings table with 10,000 rows of data. You discover that the Paintings table was created in the dbo schema. It must be in the ArtGallery schema. What should you execute to correct the problem? a) ALTER TABLE Paintings SWITCH ArtGallery b) ALTER SCHEMA ArtGallery TRANSFER Paintings c) ALTER TABLE Paintings MOVE TO ArtGallery d) CREATE TABLE ArtGallery. Paintings (ID int, Title nvarchar) Go SELECT " INTO ArtGallery.Paintings FROM dbo.paintings DROP TABLE Paintings 10. You have a SQL Azure database.
