Exam : Microsoft 70-453
Title : UPG: Transition Your MCITP SQL DBA 2005 to MCITP SQL 2008


1. You are the administrator of your company network. There's a SQL Server 2008 instance which hosts a large sales database in your company. The database uses the following backup strategies:
A transaction log backup is performed hourly.
A differential backup is performed every day.
A full database backup is performed once a week.
You intend to run an end-of-year batch process which will change about four percent of data within the database. And the process takes about two hours to run.
If something unexpected happens, such as the Sales department disapprove the process, you must make sure that the batch operation can be rolled back as soon as possible.
What should you do before starting the batch process?
A. You should create a database snapshot
B. You should perform a differential backup
C. You should create a marked transaction. Perform a transaction log backup
D. You should record the time before the batch operation. Perform a transaction log backup
Answer: A

2. You are the administrator of your company network. And you're in charge of SQL Server 2008 instance. Now you deploy a new database named TCK which manages large documents. The documents will be revised sometimes. Fast read access must be permitted by developing a table structure. Meanwhile, you have to reduce storage space requirements. So what action should you perform? (Each correct answer presents part of the solution. Choose two.)
A. You should use NTFS file system compression on the volume
B. You should use row-level compression on the document table
C. You should use varbinary(MAX) data type with FILESTREAM storage
D. You should enable row-level compression on all columns that use the vardecimal() data type.
Answer: AC

3. You are the administrator of your company network. And you're in charge of a SQL Server 2008 infrastructure. Now you intend to design a maintenance strategy for a mission-critical database. And the database has a large table named DPT. Index maintenance operations are also included in the design plan. When designing the strategy, you must consider the following matters:
The DPT table contains a column of the xml data type and is constantly accessed. New rows are frequently added to the DPT table. The average fragmentation for the clustered index of the Orders table is less than 2 percent.
In order to optimize the performance of the queries on the table, you have to run the strategy. So what action should you perform?
A. You should drop the clustered index of the DPT table
B. You should rebuild the clustered index of the DPT table offline once a month
C. You should reorganize the clustered index of the DPT table by decreasing the fill factor.
D. You should exclude the clustered index of the Orders table from scheduled reorganizing or rebuilding operations
Answer: D

4. You are the administrator of your company network. And you are in charge of a SQL Server 2008 instance. Now you intent to deploy a third-party database application which uses stored procedures to the instance. And the stored procedures are created by using SQL CLR integration. You should perform a configuration on the application so that the EXTERNAL_ACCESS code can access security setting. You must make sure that when you deploy the database to the instance, there's no loss of functionality. So what should you do first?
A. You should replace the readwrite non-static fields in the code with static fields
B. You should replace read-only static fields in the code with readwrite static fields
C. You should identify whether the code meets the type-safety requirements by using the peverify.exe PEVerify tool.
D. You should register the assembly on the server before deployment by using the regasm.exe assembly registration tool
Answer: C

5. You are the administrator of your company network. And you are in charge of a SQL Server 2008 instance. You intend to design the security requirements for a new database application which uses a code segment. The code segment includes the components bellow:
A class definition which uses public static fields
A method which accesses the registry on the SQL Server
A method which accesses the file system on a network file server
The code segment also uses SQL CLR integration and is implemented as a single assembly.
So what should you do to deploy the application to the instance successfully?
A. You should use the SAFE code access security for the assembly
B. You should replace all public static fields with public fields
C. You should replace all public static fields with public static read-only fields. Use the EXTERNAL_ACCESS code access security for the assembly.
D. You should replace all public static fields with public static read-only fields. Register the assembly by using the regasm.exe utility before deployment.
Answer: C

6. You are the administrator of your company network. There's a SQL Server 2008 instance which hosts a new database application in your company. Now you want to develop the security requirements for the application. Each application user has his own login to the SQL Server 2008 server. The application database executes stored procedures in the MSDB database in which the stored procedures schedule SQLAgent jobs. You must make sure that the the stored procedures in the MSDB database are executed by using the security context of the application user. So what action should you perform?
A. You should add each user to the public role in the MSDB database
B. You should add each user to the dbdtsltduser database role in the MSDB database
C. You should configure the MSDB database to use the TRUSTWORTHY option, and then add each user to the MSDB database
D. You should configure the new database to use the TRUSTWORTHY option, and then add each user to the MSDB database.
