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.
Correct Answer:

Explanation:
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 Agencyand published by the United StatesNISTas a USFederal Information Processing Standard.SHA stands for "secure hash algorithm".The four SHAalgorithmsare structured differently and are distinguished asSHA-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
In Object Explorer, connect to an instance of Database Engine.
On the Standard bar, click New Query.
Copy and paste the following example into the query window and click Execute.
USE AdventureWorks2012;
--If there is no master key, create one now.
IF NOT EXISTS
(SELECT * FROM sys.symmetric_keys WHERE symmetric_key_id = 101)
CREATE MASTER KEY ENCRYPTION BY
PASSWORD = '23987hxJKL95QYV4369#ghf0%lekjg5k3fd117r$$#1946kcj$n44ncjhdlj' GO CREATE CERTIFICATE Sales09 WITH SUBJECT = 'Customer Credit Card Numbers'; GO CREATE SYMMETRIC KEY CreditCards_Key11 WITH ALGORITHM = AES_256 ENCRYPTION BY CERTIFICATE Sales09; GO
-- Create a column in which to store the encrypted data.
ALTER TABLE Sales.CreditCard
ADD CardNumber_Encryptedvarbinary(128);
GO
-- Open the symmetric key with which to encrypt the data.
OPEN SYMMETRIC KEY CreditCards_Key11
DECRYPTION BY CERTIFICATE Sales09;
-- Encrypt the value in column CardNumber using the
-- symmetric key CreditCards_Key11.
-- Save the result in column CardNumber_Encrypted.
UPDATE Sales.CreditCard
SET CardNumber_Encrypted = EncryptByKey(Key_GUID('CreditCards_Key11')
, CardNumber, 1, HashBytes('SHA1', CONVERT( varbinary
, CreditCardID)));
GO

You need to migrate alerts and e-mail notifications.
Which system stored procedures should you use? (Each correct answer presents part of the solution. Choose all that apply.)
Correct Answer: B,D 🗳️
You are designing two stored procedures named Procedure1 and Procedure2.
You identify the following requirements:
* Procedure1 must take a parameter that ensures that multiple rows of data can pass into the stored procedure.
* Procedure2 must use business logic that resides in a Microsoft .NET Framework assembly.
You need to identify the appropriate technology for each stored procedure.
Which technologies should you identify?
To answer, drag the appropriate technology to the correct stored procedure in the answer area. (Answer choices may be used once, more than once, or not at all.)
