Question: 1 Your company has a SQL Azure subscription. You implement a database named Database1. Database1 has two tables named Table1 and Table2. You create a stored procedure named sp1.Sp1 reads data from Table1 and inserts data into Table2. A user named User1 informs you that he is unable to run sp1. You verify that User1 has the SELECT permission on Table1 and Table2. You need to ensure that User1 can run sp1. The solution must minimize the number of permissions assigned to User1. What should you do? A. Grant User1 the INSERT permission on Table2. B. Add User1 to the db_datawriter role. C. Change sp1 to run as the sa user. D. Grant User1 the EXECUTE permission on sp1.

Answer: D Question: 2 You use SQL Server 2012 to maintain the data used by the applications at your company. You plan to create a table named Table1 by using the following statement. (Line numbers are included for reference only.)

You need to ensure that Table1 contains a column named UserName. The UserName column will: • Store string values in any language. • Accept a maximum of 200 characters. • Be case-insensitive and accent-insensitive Which code segment should you add at line 03? A. UserName varchar(200) COLLATE Latin1_General_CI_AI NOT NULL. B. UserName nvarchar (200) COLLATE Latin1_General_CI_AI NOT NULL. C. UserName nvarchar(200) COLLATE Lati1l_General_CS_AS NOT NULL.

D. UserName varchar(200) COLLATE Latin1 General CS AS NOT NULL.

Answer: B Question: 3 DRAG DROP You have a table named Table1 that contains 1 million rows. Table1 contains a column named Column1 that stores sensitive information. Column1 uses the nvarchar (16) data type. You have a certificate named Cert1. You need to replace Column1 with a new encrypted column named Column2 that uses one-way hashing. Which code segment should you execute before you remove Column1? To answer, move the appropriate code segments from the list of code segments to the answer area and arrange them in the correct order.

Explanation: Box 1: First create a hash key using the certificate. Not AES: AES is not based on hashing. Box 2: Add a column with varbinary data type. Box 3: Box 4: Note: * There are a few different hashing algorithms available in SQL Server 2005: MD2, MD4, MD5, SHA, SHA1, with each having pros and cons. * In cryptography, SHA-1 is a cryptographic hash function designed by the United States National Security Agency and published by the United States NIST as a US Federal Information Processing Standard . SHA stands for " secure hash algorithm ". The four SHA algorithms are structured differently and are distinguished as SHA-0 , SHA-1 , SHA-2 , andSHA-3 . SHA-1 is very similar to SHA-0, but corrects an error in the original SHA hash specification that led to significant weaknesses. The SHA-0 algorithm was not adopted by many applications. SHA-2 on the other hand significantly differs from the SHA-1 hash function. SHA-1 is the most widely used of the existing SHA hash functions, and is employed in several widely used applications and protocols. * To encrypt a column of data using a simple symmetric encryption

You need to create the missing index. Which code segment should you execute? A. CREATE NCNCLUSTERED INDEX 1X1 on Schema1.Table1 (Column1) INCLUDE (Column4) B. CREATE NCNCLUSTERED INDEX 1X1 on Schema1.Table1 (Column1) C. CREATE NONCLUSTERED INDEX 1X1 on Schema1.Table1 (Column1, Column2, Column3) INCLUDE(Column4) D. CREATE NONCLUSTERED INDEX 1X1 on Schema1.Table1 (Column1) INCLUDE(Column4) WHERE Column2 <> Column3

Answer: C Question: 5 You are creating a table to support an application that will cache data outside of SQL Server. The application will detect whether cached values were changed before it updates the values. You need to create the table, and then verify that you can insert a row into the table. Which code segment should you use?

Question: 6 DRAG DROP You run the following code segment:

After you add 10,000 rows to Customers, you discover that the index is fragmented. You need to defragment the index in the least amount of time. Which code segment should you execute? To answer, drag the appropriate value to the correct location in the code segment in the answer area. (Answer choices may be used once, more than once, or not at all.)

Explanation: Note: Locking the table during the process and not recomputing statistics would be the fastest. * Online = OFF Table locks are applied for the duration of the index operation. An offline index operation that creates, rebuilds, or drops a clustered, spatial, or XML index, or rebuilds or drops a nonclustered index, acquires a Schema modification (Sch-M) lock on the table. This prevents all user access to the underlying table for the duration of the operation. An offline index operation that creates a nonclustered index acquires a Shared (S) lock on the table. This prevents updates to the underlying table but allows read operations, such as SELECT statements. * STATISTICS_NORECOMPUTE = ON Out-of-date statistics are not automatically recomputed. Reference: ALTER INDEX (Transact-SQL)
