If the tables were located on the same filegroup, the disk access to the data would be sequential and therefore much slower than a parallel disk read However, this is not an infinite linear increase in disk I/O throughput Data still has to be acted upon by processors, and processors manage the I/O threads that are open A general rule of thumb is to limit the number of filegroups to be equivalent to the number of processors on your system This ensures that the processor does not become the bottleneck within disk I/O operations For databases with significant write activity, you should always place the transaction log on a different set of disks This isolates the sequential write activity of the transac tion log from the random read/write activity within a data file.

1. Correct Answer: D A. Incorrect: The Move Mailbox Wizard uses the OS scheduling facilities and waits until the time selected before sending commands to Exchange Management Shell. One Exchange Management Shell command is generated for each mailbox to be moved. B. Incorrect: The Move Mailbox Wizard uses the OS scheduling facilities and waits until the time selected before sending commands to Exchange Management Shell.

1. Log on as Administrator. 2. Open Event Viewer from the Administrative Tools folder. 3. Select the Security log. 4. What types of events do you see in the Security log Only Object Access events Other types of events Remember that policies can enable auditing for numerous security-related actions, including directory service access, account management, logon, and more. 5. To filter the log and narrow the scope of your search, choose the Filter command from the View menu. 6. Configure the filter to be as narrow as possible. What do you know about the event you are trying to locate You know it is a success or failure audit; that it is an Object Access event category; and that it occurred today. Check your work by referring to Figure 6-15. 7. Click Apply. 8. Can you more easily locate the event that marked Danielle s deletion of the Report file Open the event and look at its contents. The description indicates the user and the file and the action. You could not filter for contents of the description in Event Viewer, but you could do so by exporting the file to a log analysis tool or to Microsoft Office Excel. 9. (Optional) If you have access to Microsoft Office Excel, right-click the Security log node and choose Save Log File As. Enter a name and select Comma-Delimited as the file type. Open the file in Office Excel.

The majority of the time spent in disk I/O operations is with positioning the disk head over the appropri ate disk sector to read or write data Because a transaction log is always written sequentially, the disk heads move in essentially a linear manner By isolating the trans action log from data files, you can increase write throughput by ensuring that the disk head does not have to constantly reposition in order to write changes Keep in mind that the maximum write throughput you can ever achieve in a database is the maxi mum amount of data per unit time that can be written to a transaction log In addition to using multiple files placed on multiple disk sets, you can take advan tage of another write algorithm that SQL Server uses: proportional fill Filegroups represent the storage space boundary for objects within a database.

cannot apply a particular change. This typically occurs because of a difference in constraint definitions between the Publisher and Subscriber, combined with the setting in the NFR option on the constraint. Examples include the following:

However, the files within a filegroup store the physical data You can configure files to automati cally grow when additional space is needed SQL Server generally grows files along a filegroup boundary To limit growth operations to a filegroup boundary, all files.
