The Log Reader Agent, logread.exe, is used only with transactional replication. It is used to extract committed transactions from the transaction log on the publisher that need to be replicated. Once extracted, the Log Reader Agent ensures that each trans action is repackaged and written into the distribution database in exactly the same sequence as the transaction was issued against the publisher. The sequencing by the Log Reader Agent is critical to ensure that transactions are not applied out of order to a subscriber.

Answers to these questions and explanations of why each answer choice is right or wrong are located in the Answers section at the end of the book.

Note that using the RESTORE VERIFYONLY statement verifies only the structure of the backup, not the actual data on the pages within this backup. However, if a backup is created with the CHECKSUM option, you can then verify the backup by using the RESTORE VERIFYONLY statement with the CHECKSUM option. This option can provide a good indication of the reliability of both the structure and the data of the backup.

project and service changes in a predictable and repeatable manner, while minimizing the risks inherent in those changes.

You could customize an administrative template with the required settings, save the template, and then export it on each computer in the workgroup.

As you might remember from the study you have undertaken for previous SQL Server 2005 exams, constraints are limitations on the data that users can insert in a column of a database table. UNIQUE or PRIMARY KEY constraints prevent users from inserting a value that already exists within the column, and CHECK constraints prevent users from inserting values that do not meet a particular rule. In the context of SQL Server 2005, an implicit constraint is a business rule. Implicit constraints could be anything from no contractor can bill more than 60 hours in a week to the maximum number of items that a customer can order at any one time. As a database administrator, you might be responsible for ensuring that the database reflects the policy rules of the business. An explicit constraint is one that the administrator applies to the database. Following from the example just mentioned, the database administrator would implement an explicit constraint by programming the database so that it would be impossible for a contractor to enter a value higher than 60 hours per week into the organization s billing database.

The IP Security Monitor snap-in improves on the Ipsecmon.exe tool in Win dows 2000. (New in Windows XP Professional and Windows Server 2003.) A stronger cryptographic master key is introduced, Diffie-Hellman 2048-bit. The Netsh command-line management tool provides convenience, plus many configuration possibilities that are not available from the IP Security Policy Management snap-in. Computer startup security (or stateful filter), if configured, is activated at startup and manages network traffic during startup. It allows only the outbound traffic that the computer initiates during startup, inbound traffic sent in response to the outbound traffic, and DHCP traffic. The persistent policy is applied if the local policy or the Active Directory directory service IPSec policy cannot be applied. Only Internet Key Exchange (IKE) traffic is exempt from traffic filters. This restriction is required in order to establish secured communication. Certain restrictions determine which computers are allowed to connect by domain, by certificate origin, or by computer group.
