To further practice and reinforce the skills you learned in this chapter, you can perform the following tasks:

ithin many applications you need to construct queries that go beyond a basic SELECT statement, such as creating running totals, finding gaps in sequences, traversing a recursive hierarchy, or ranking data within a set. In this chapter, you will learn how to extend the querying techniques that you have learned within this book to encompass subqueries, common table expressions (CTEs), and ranking functions.

In the real world, you would rarely want users to have permission to log on locally to a domain controller, however, in our one-system test environment, this capability is important. Although there are several ways to achieve this goal, the easiest is to add the Domain Users group to the Print Operators group. The Print Operators group has the right to log on locally. 1. Open Active Directory Users And Computers. 2. In the tree pane, select the Builtin container. 3. Open the Properties of the Print Operators group. 4. Use the Members tab to add Domain Users to the group.

John earned his MCDST and is in the process of obtaining an entry-level IT job. He enjoys working with people, but he also enjoys the hands-on aspect of the technology. He has several computers at home, and he has connected them and configured a small domain just for the fun of it. He likes working inside the computer, too, adding mem ory, replacing cards, and so on. He is certain that someday he wants to own his own computer-repair or network-consulting business. He wants to make sure that he gets the best work experience possible. 1. What type of entry-level job do you think is best for John as he works to meet his goals Why

The DELETE statement allows you to remove from the database rows that are no longer required. With the DELETE statement, entire rows of data are removed from the table. If you want to simply remove a value from a column in a given row, you should use an UPDATE statement.

4. In Exchange Management Shell, issue the command Suspend-StorageGroupCopy Identity Replicate. When you are prompted to confirm this action, type A and press Enter. 5. Issue the command Get-StorageGroupCopyStatus Identity Replicate again to verify that the Replicate storage group now has the status Suspended, as shown in Figure 13-8. 6. Issue the command Resume-StorageGroupCopy Identity Replicate to resume LCR. 7. Verify that LCR has resumed by reissuing the Get-StorageGroupCopyStatus Identity Replicate command.

Select a method for deploying configuration settings to Windows 7 workstations. Understand the process of creating and deploying Group Policy objects. Understand the differences between startup/shutdown scripts and logon/logoff scripts.

Why are statistics important to query performance During its evaluation of a query, the query optimizer uses the statistical information to estimate the cost of using an index and determine the optimal query plan for a query.

You should use System Restore. Most likely, Ken did not create a manual restore point, and it is also unlikely that the setup program for the backup utility created one. You should find the most recent automatic restore point and restore the computer to that point.

Although every laptop is different, certain basic components do not vary. This section introduces the major components of a laptop and where they can usually be found.

Obtaining Diagnostic IPSec Information One of the steps in diagnosing IPSec problems or just establishing that the policy is working like you think it should is to obtain information about the current policy. The Show commands described later in Table 11-7 provide that information. The information that each command reveals iden tifies the settings in the policy. For example, the Show Filterlist command lists the infor mation in the policies filter list. Filter list options were listed in Table 11-6. Some examples of the Show command syntax are illustrated next. In the commands, the equal sign is part of the command and the italicized words are replaced by some value as indicated below the command.
