You administer a Microsoft SQL Server 2012 database. You configure Transparent Data Encryption (TDE) on
the Orders database by using the following statements:
<code>
CREATE MASTER KEY ENCRYPTION BY PASSWORD = ‘MyPassword1!’;
CREATE CERTIFICATE TDE_Certificate WITH SUBJECT = ‘TDE Certificate’;
BACKUP CERTIFICATE TDE_Certificate TO FILE = ‘d:\TDE_Certificate.cer’
WITH PRIVATE KEY (FILE = ‘d:\TDE_Certificate.key’, ENCRYPTION BY PASSWORD =
‘MyPassword1!’);
CREATE DATABASE ENCRYPTION KEY
WITH ALGORITHM = AES_256
ENCRYPTION BY SERVER CERTIFICATE TDE_Certificate;
ALTER DATABASE Orders SET ENCRYPTION ON;
</code>
You attempt to restore the Orders database and the restore fails.
You copy the encryption file to the original location. A hardware failure occurs and so a new server must be
installed and configured.
After installing SQL Server to the new server, you restore the Orders database and copy the encryptionfiles to
their original location. However, you are unable toaccess the database.
You need to be able to restore the database.
Which Transact-SQL statement should you use before attempting the restore?
A.
CREATE ASSEMBLY TDE_Assembly
FROM ‘d:\TDE_Certificate.cer’
WITH PERMISSION_SET = SAFE;
GO
CREATE CERTIFICATE TDE_Certificate
FROM ASSEMBLY TDE_Assembly;
B.
CREATE CERTIFICATE TDE_Certificate
FROM EXECUTABLE FILE = ‘d:\TDE_Certificate.cer’
C.
CREATE CERTIFICATE TDE_Certificate
FROM FILE = ‘d:\TDE_Certificate.cer’
WITH PRIVATE KEY (FILE = ‘d:\TDE_Certificate.key’, DECRYPTION BY PASSWORD
‘MyPassword1!’);
D.
DECLARE @startdate date
SET @startdate = GETDATE()
CREATE CERTIFICATE TDE_Certificate
FROM FILE = ‘d:\TDE_Certificate.cer’
WITH START_DATE = @startdate;
