Microsoft PRO:MS SQL Serv 08,Design,Optimize, and Maintain DB Admin Solu - 70-450 Exam Practice Test
You are a professional level SQL Sever 2008 Database Administrator.
A new database should be deployed, and the capacity requirements listed below should be satisfied.
There should be 275 GB for the database data file, while there should be 50 GB for the transaction log file. There are six 100-GB disk drives which are accessible for the database in the storage array. The six disks are attached to a redundant array of independent disks (RAID) controller, and the controller supports
RAID levels 0, 1, 5, and 10.
Since you are the technical support, you are required to maximize the write performance of the transaction
log. In addition, you should protect the database and transaction log files,
when a drive fails.
The storage system should be designed.
From the following four storage configuration, which one should you utilize?

You administer a SQL Server 2008 instance.
The instance hosts a database that is used by a Web-based application. The application processes 15,000 transactions every minute. A table in the database contains a column that is used only by the application. This column stores sensitive data.
You need to store the sensitive data in the most secure manner possible.
You also need to ensure that you minimize the usage of memory space and processor time.
Which encryption type should you use?

You administer a SQL Server 2008 instance.
You plan to design a monitoring solution for the instance to monitor object usage statistics.
The solution must identify a list of first 10 objects for each of the following components:
Most frequently executed stored procedures and functions
Long running Transact-SQL statements
You need to implement the monitoring solution to minimize performance effect by using the least amount of administrative effort.

You administer a SQL Server 2008 instance that hosts a large database.
The following backup strategy is used for the database:
A full database backup is performed at 02:00 hr every Monday.
A differential backup is performed at 23:00 hr every day.
A transaction log backup is performed on an hourly basis.
A power failure on Thursday causes the SQL Server 2008 server to restart at 09:15 hr.
Fifteen minutes after the server restarts, the users report that they are unable to execute certain queries
that access
customer data. You discover that the customer data is unmodified after the power failure.
When you execute the DBCC CHECKDB command on the database, you receive the following error
message:
Object ID 2814307832, index ID 2, partition ID 83127819437122157, alloc unit ID 82134587923221126
(type In-row data): Page (3421:169) could not be processed. See other errors for d etails.
Table error: Object ID 2814307832, index ID 2, partition ID 83127819437122157, alloc unit ID
82134587923221126 (type In-row data), page (3421:169). Test (IS_OFF (BUF_IOERR, pBUF- > bstat))
failed. Values are 16928422 and -8.
CHECKDB found 0 allocatio n errors and 2 consistency errors in table 'tbl_Customer' (object ID
2814307832).
When you execute the sp_help 'tbl_customer' stored procedure you receive the following result set:
index_name index_description
PK clustered located on PRIMARY
NCIX nonclustered located on PRIMARY
You need to ensure that the data is available as quickly as possible with minimal effect on users.

You administer a SQL Server 2008 infrastructure.
Several production databases use Transparent database encryption.
You perform full database backups of the production databases as part of your backup strategy.
You need to ensure that the database backups can be restored on another SQL Server 2008 instance if the original host server fails.

You are a professional level SQL Sever 2008 Database Administrator.
The largest table in a database is partitioned into four equal-sized parts.
The first two partitions are seldom queried, while the third partition is regularly queried by several reports. Meanwhile, the fourth partition is heavily queried and regularly modified.
The disk space of the table should be cut to the least and the query performance should be with the least impact.

After a regular test, you find that performance degradation is experienced by an instance for the three reasons:
Excessive CPU usage, Server processes paging and Deadlocks
A monitoring solution should be implemented to provide data, monitor and troubleshoot performance issues and detailed deadlock information should be contained in the provided data.
You should utilize the least amount of administrative effort to finish the task.

Two SQL Server 2008 instances are managed by you, and they are respectively called Ins01 and Ins02.
The Sales database is included in Ins01, while the Accounts database is contained by Ins02. A transaction
is
started by A procedure in the Sales database. And then, the Sales.dbo.Order table and the Accounts.dbo.
OrderHistory table are updated by the procedure through a linked server.
Since you are the technical support of the company, you are required to make sure that a
two-phase commit is utilized by the transaction.
