Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu Sample Questions:

1. You are planning to upgrade a database application that uses merge replication.
The table currently has a column type of UNIQUEIDENTIFIER and has a DEFAULT constratin that uses
the NEWID() function.
A new version of the application requires that the FILESTREAM datatype be added to a table in the
database.
The data type will be used to store binary files. Some of the files will be larger than 2 GB in size.
While testing the upgrade, you discover that replication fails on the articles that contain the FILESTREAM
data.
You find out that the failure occurs when a file object is larger than 2 GB.
You need to ensure that merge replication will continue to function after the upgrade.
You also need to ensure that replication occurs without errors and has the best performance.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A) Change the DEFAULT constraint to use the NEWSEQUENTIALID() function.
B) Place the table that will contain the FILESTREAM data type on a separate filegroup.
C) Use the sp_changemergearticle stored procedure and set the @stream_blob_columns option to true for the table that will use the FILESTREAM data type.
D) Drop and recreate the table that will use the FILESTREAM data type.

2. You administer SQL Server 2008 instances at three sites.
All sites share a mission-critical database. The business requirements specify that users at each site must be able to perform the following tasks:

You need to provide a high-availability solution that meets the business requirements.
Which solution should you implement?
