A thick arrow represents a large number of rows moving from one operation in the execution plan to another. The greater the number of rows transferred from one operation to another, the thicker the arrow. If a hash operation is used to handle clauses such as GROUP BY and JOIN, it often means that an appropriate index did not exist to optimize the query.

The Windows Ribbon framework is the Windows implementation of the Office Fluent User Interface. Although the Ribbon in Office 2007 is similar in concept to the one in Windows 7, it s a little bit different in appearance. Office 2010 has the same look and feel of the Windows 7 Ribbon. Keep in mind that there are many other Ribbon technologies for Native (C/C++) and Managed (.NET) code that are available, ranging from the free ones in the Windows

The DataTable itself assigns values to an auto-incrementing column in the table. This is typical of a table that contains information such as order information where it is desirable to have a unique OrderID, but the actual value of the OrderID column isn t important other than that it needs to be unique. DataColumn objects provide specific properties to create auto-incrementing columns where you can set the starting value, called the AutoIncrementSeed, as well as the increment, or number added to the last value, which is called the AutoIncrementStep. The following code sample shows how to create an auto-increment column that cre ates records with a SalesOrderID value starting at 100, and adds 5 to the previous value with each new row added. In other words, the first record created will have a value of 100 in the SalesOrderID column, and the next row will have a value of 105, the next row 110, and so on.

D. Incorrect: The business requirements of the backup procedure are to max imize performance and store backups on a fault-tolerant volume. Mirrored media sets cannot be of mixed types, so this answer does not provide a fea sible solution. 3. Correct Answer: B A. Incorrect: This sequence is incorrect because you need to restore only the last differential backup. B. Correct: To restore the database, you need to first restore the full backup and then the last differential backup (if any) since the full backup. Then you need to apply all the transaction log (including the tail-log) backups, in order, since the last data backup. C. Incorrect: This sequence is provided in the reverse order. In addition, you need to restore only the last differential backup. D. Incorrect: This sequence is provided in the reverse order. 4. Correct Answer: C A. Incorrect: A full backup disrupts the backup schedule of the Order database. B. Incorrect: A partial backup is like a full backup, except that any extra (non primary) read-only filegroups are not backed up by default. A partial backup disrupts the backup schedule configured for the Order database. C. Correct: A copy-only backup enables you to provide a copy of the backup without affecting the backup schedule of the Order database. D. Incorrect: A file backup is a backup of a single database file. A file backup disrupts the backup schedule configured for the Order database.
