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

1. You administer a SQL Server 2008 infrastructure.
You plan to deploy a new SQL Server 2008 multi-node failover cluster. The failover cluster uses a storage
area network (SAN)
that will use redundant array of independent disks (RAID) level 5.
You need to format the logical unit numbers (LUNs) for optimal performance of the database data files.
Which of the following is the best allocation unit size you should use?

A) 156-KB
B) 8-KB
C) 32-KB
D) 64-KB

2. You administer a SQL Server 2008 database solution.
All data modifications are performed through stored procedures that use only the INSERT, UPDATE, or DELETE statements. You are designing a backup strategy.
You need to ensure that the following business requirements are met:
The backup strategy supports point-in-time recovery for failure at any time of day.
The transaction log uses the least amount of disk space.
What should you do?

A) Use the full-recovery model along with differential backups.
B) Use the simple-recovery model along with differential backups.
C) Use the full-recovery model along with transaction log backups.
D) Use hourly database snapshots.

3. You are a professional level SQL Sever 2008 Database Administrator.
A business-critical database is hosted by the instance, and the database must be constantly available to the users with no data loss. Filestream data is contained by the database.
A high-availability solution should be designed for the site.
Which solution should be utilized?

A) Database snapshot should be utilized.
B) Failover clustering should be utilized.
C) Synchronous database mirroring with a witness server should be utilized.
D) Asynchronous database mirroring should be utilized.

4. You administer a SQL Server 2008 infrastructure.
An instance contains a database that includes a large table named OrderDetails. The application queries
only execute
DML statements on the last three months data. Administrative audits are conducted monthly on data older
than three months.
You discover the following performance problems in the database. The performance of the application
queries against the
OrderDetail table is poor. The maintenance tasks against the database, including index defragmentation,
take a long time.
You need to resolve the performance problems without affecting the server performance.
What should you do?

A) Create an additional table named OrderDetailsHistory for data older than three months. Create a SQL Server Agent job that runs the following Transact-SQL statement every month. INSERT INTO OrderDetailsHistory SELECT * FROM OrderDetails WHERE DATEDIFF( m,OrderDate,GETDATE ()) > 3
B) Create an additional table named OrderDetailsHistory for data older than three months. Partition the OrderDetails and OrderDetailsHistory tables in two parts by using the OrderDatecolumn. Create a SQL Server Agent job that runs every month and uses the ALTER TABLE...SWITCH Transact-SQL statement to move data that is older than three months to the OrderDetailsHistory table.
C) Create a database snapshot for the OrderDetails table every three months. Modify the queries to use the current snapshot.
D) Create an additional table named OrderDetailsHistory for data older than three months. Use the following Transact-SQL statement. CREATE TRIGGER trgMoveData ON OrderDetails AFTER INSERT AS INSERT INTO OrderDetailsHistory SELECT * FROM OrderDetails WHERE DATEDIFF( m,OrderDate,GETDATE ()) > 3

5. You administer four SQL Server 2008 instances. Each instance hosts a single database application.
You plan to migrate all four instances to a new SQL Server failover cluster. The four instances are configured as shown in the following table.
Instance Name Configuration:
Instance 1 8 processors that have 16-GB RAM Instance 2 4 processors that have 8-GB RAM Instance 3 2 processors that have 16-GB RAM Instance 4 4 Processors that have 8-GB RAM
The four instances are fully optimized and have no spare CPU cycles or extra memory. The new cluster will host all four databases on a single virtual cluster IP address. You need to ensure that the new cluster is configured to handle the workload of all the database applications by using the minimum amount of hardware resources.
Which cluster configuration should you use?

A) Two-node active/passive cluster that has each node containing a minimum of 18 processors and a 50GB memory
B) Four-node active/active/active/passive cluster that has each node containing a minimum of 18 processors and a 50-GB memory
C) Four-node active/active/active/active cluster that has each node containing a minimum of 9 processors and a 25-GB memory
D) Two-node active/active cluster that has each node containing a minimum of 9 processors and a 25-GB memory
