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

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

2. You administer a SQL Server 2008 instance.
The instance is one of three servers in a peer-to-peer transactional replication topology.
The publication contains a table named Orders. The Orders table contains 200 GB of data
across multiple partitions. A batch process bulk loads 10 GB of data to the Orders table periodically.
You need to design a replication strategy to minimize latency.
What should you do?

A) Disable the Distributor agent. Use the BULK INSERT command in the Orders table. Reinitialize the publication.
B) Explanation/Reference:
---Jeff---
C) Configure the Distributor agent to change the commit batch threshold.
D) Configure the Distributor agent to replicate transactions continually.
E) Use the BULK INSERT command in multiple staging tables. Switch partitions into the Orders table.

3. You are a professional level SQL Sever 2008 Database Administrator.
A new database named Engineering is deployed. Large documents are managed by the Engineering
database,
and the documents will be revised occasionally. A table structure should be designed to permit fast read
access.
The storage space requirements should be cut to the least.
What will you do to achieve the goal? (Choose more than one.)

A) To achieve the goal, NTFS file system compression should be utilized on the volume.
B) To achieve the goal, row-level compression should be utilized on the document table.
C) To achieve the goal, varbinary(MAX) data type should be utilized with FILESTREAM storage.
D) To achieve the goal, row-level compression should be enabled on all columns that the vardecimal() data type is utilized.

4. 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.
What should you do?

A) Drop and recreate the NCIX index.
B) Drop and recreate the PK index.
C) Restore the latest full database backup. Restore the latest differential backup. Restore all transaction log backups from the latest differential backup.
D) Restore the latest full database backup. Restore all transaction log backups from the latest full database backup.

5. You administer a SQL Server 2008 instance.
Customers report server performance degradation because of a newly implemented process. You use Dynamic Management Views to verify that there are no long running queries.
You need to correlate the operating system performance data with the actual query execution trace by using minimum administrative effort.
What should you do?

A) Use Data Collector.
B) Use SQL Server Profiler and System Monitor.
C) Use the SQLdiag.exe utility.
D) Use SQL Server Profiler and the tracerpt.exe utility.
