1. Correct Answers: B, C, E, and F A. Incorrect: The RSACryptoServiceProvider class provides asymmetric encryption, which requires the encryptor and decryptor to have related but different keys. B. Correct: The RijndaelManaged class provides symmetric encryption, which requires the encryptor and decryptor to have the same keys. C. Correct: The TripleDES class provides symmetric encryption, which requires the encryptor and decryptor to have the same keys. D. Incorrect: The DSACryptoServiceProvider class provides asymmetric digital signing, which requires the encryptor and decryptor to have related but different keys. E. Correct: The DES class provides symmetric encryption, which requires the encryptor and decryptor to have the same keys. F. Correct: The RC2 class provides symmetric encryption, which requires the encryptor and decryptor to have the same keys. 2. Correct Answers: A, C, and D A. Correct: SymmetricAlgorithm.Key must be the same on both the encryptor and decryptor. B. Incorrect: Symmetric encryption algorithms do not use a salt. Salts are used when creating keys from passwords using the Rfc2898DeriveBytes class. C. Correct: SymmetricAlgorithm.IV must be the same on both the encryptor and decryptor. D. Correct: SymmetricAlgorithm.Mode must be the same on both the encryptor and decryptor. 3. Correct Answer: C A. Incorrect: When transferring data across a network, you need to export only the public key. Because you can create new keys for future network sessions, there is no need to save the private key. B. Incorrect: If you are decrypting a file encrypted by a remote computer, you should provide the remote computer your public key. You do not need to export your private key.

Database environments that have additional server resources can perform a side-byside migration of their SQL Server 7.0 or SQL Server 2000 installations to SQL Server 2005. Side-by-side migrations involve installing SQL Server 2005 either on the same server or on a different server as your previous SQL Server installations. Having the old environment still active during the upgrade process allows for the continuous operation of the original database environment while you install and test the upgraded environment. Side-by-side migrations can often minimize the amount of downtime for the SQL Server environment. Table 1-4 shows the support for side-byside migration when upgrading from different versions of SQL Server to SQL Server 2000 (32-bit and 64-bit) and SQL Server 2005 (32-bit and 64-bit).

the same way you partition the table. In Lesson 5 of this chapter, we will discuss why this is important. When you create this index, SQL Server stores the portion of the index that corresponds to a CustomerAddressID less than or equal to 1,000 in FG1, stores the portion from 1,001 to 2,000 in FG2, and so on.

Let s begin by looking at a very basic example of two subnets, each containing one WINS server that supports a couple of hundred users. See Figure 7-8.

Choose column data types to reduce storage requirements across the enterprise. Design appropriate use of varchar across the enterprise. Denormalize entities to minimize page reads per query. Optimize table width.
