2. How can inventory in each winery s database be queried and updated by central office users A. Create an HTTP endpoint with the BATCHES option enabled for use by central office users. B. Create a certificate for central office users that will authenticate to each win ery s database. C. Create an HTTP endpoint with the SSL and BATCHES options enabled for use by central office users. D. Create an HTTP endpoint with the CLEAR ports option. 3. What is the best way to allow central office users to access data in each winery s database without needing to open an HTTP endpoint to ad hoc queries, with the least amount of administrative effort A. Create a Windows group in the domain, add the Windows group to each winery s database, and grant appropriate database permissions to the group. B. Create a local Windows group on each server, add the Windows group to each winery s database, and grant appropriate database permissions to the group. C. Add each user s Windows login to each database and grant appropriate permissions. D. Create a SQL Server login on each database for each user and grant appro priate permissions.

DMVs, introduced in SQL Server 2005, are increasingly used for a variety of tasks, one of which is to identify poorly performing queries. You can use Profiler and the DTA to debug SQL Server queries, but they need to run on a monitoring or test server because they degrade performance on a production server. Procedures that use DMVs, on the other hand, can run in a production environment. You can use (for example) the following DMVs to identify and analyze poorly performing queries:

To help you successfully master the exam objectives presented in this chapter, com plete the following practice tasks.

Application changes are needed, and it is not easy to implement and maintain. Not easy to implement and maintain and can be cumbersome if you need to search for all data.

Create an HTTP endpoint that exposes each of the stored procedures in the AdventureWorks database as Web methods. Write a Microsoft Visual Studio application that will make calls to the HTTP endpoint and display the results of each call in a grid attached to a DataSet object.

The practice tests on this book s companion CD offer many options. For example, you can test yourself on just one exam objective, or you can test yourself on all the 70-443 certification exam content. You can set up the test so that it closely simulates the expe rience of taking a certification exam, or you can set it up in study mode so that you can look at the correct answers and explanations after you answer each question.

This DMV contains a row for each query plan in SQL Server s query plan cache. When SQL Server removes a plan from the cache, it eliminates the corresponding row from the view. The DMV returns the following aggregate performance statistics for cached query plans:

Security was one of the major design features for Microsoft SQL Server 2005. Instead of looking at the security system as an upgrade, it is more accurate to say that the entire security system from SQL Server 2000 was removed and rearchitected. Every line of code in SQL Server 2005 was written to plug into the security architecture, pro viding the most comprehensive security that SQL Server has ever had. It is impossible to perform an action within SQL Server 2005 without directly interacting with the security system. This chapter will explain the entire security system, beginning with the SQL Server services and moving through each layer to the objects within a database.

Data partitioning involves moving data from a single database server into more than one repository. It is not uncommon for applications to perform fine when they are moved into production and then start to slow as more data is added to the database. In some cases, changes made to the application or the database, such as applying indexes, allow the application to return to acceptable performance. In cases where this is no longer possible, you might need to consider implementing a data-partitioning model. There are two kinds of data partitioning: vertical and horizontal. Vertical partitioning involves splitting a table into multiple tables. Typically, this is done to reduce data redundancy, but if a database has gone through the normalization process, this type of partitioning might not be
