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

2. You are a professional level SQL Sever 2008 Database Administrator.
They are respectively named Ins01, Ins02, Ins03 and Ins04. A single database application is hosted by each instance. All four instances should be removed to a new SQL Server failover cluster. You can see the configuration of the four instances from the table listed below:

All the four instances are sufficiently optimized, and there are no spare CPU cycles or extra memory in
the instances.
All four databases will be hosted by the new cluster on a single virtual cluster IP address.
Since you are the technical support, you are required to set the new cluster to handle the workload of all the database applications with the least amount of hardware resources.
From the four cluster configuration, which one should be utilized?

A) Two-node active/active cluster should be utilized and a minimum of 9 processors and a 25-GB memory are contained by each node.
B) Two-node active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.
C) Four-node active/active/active/active cluster should be utilized and a minimum of 9 processors and a 25-GB memory are contained by each node.
D) Four-node active/active/active/passive cluster should be utilized and a minimum of 18 processors and a 50-GB memory are contained by each node.

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

4. You are a professional level SQL Sever 2008 Database Administrator.
A large database is hosted by the instance. High volumes of queries and transactions that are
processor intensive
are experienced by the database. An incremental backup strategy should be designed for the database.
In addition,
backup compression will be utilized.
Since you are the technical support of the company, you are required to reduce the impact from the backup
jobs
on the performance of the server to the least.
Which action will you perform to achieve the goal?

A) To achieve the goal, the database backup should be spread across multiple backup devices.
B) To achieve the goal, the Affinity I/O Mask configuration option should be reconfigured.
C) To achieve the goal, database snapshots should be utilized.
D) To achieve the goal, the Resource Governor should be utilized.

5. You are a professional level SQL Sever 2008 Database Administrator.
A large database is hosted by the instance. The company utilizes the following backup strategy for the
database.
First, the performance of a full database backup is implemented at 02:00 hr every Monday.
Secondly, the performance of a differential backup is implemented at 23:00 hr every day.
Thirdly, the performance of a transaction log backup is implemented on an hourly basis.
A reboot is caused on the SQL Server 2008 server by a power failure at 09:15 hr, Thursday.
Fifteen minutes after the reboot of the server, it is reported that certain queries that access customer data
cannot be executed. You find that the customer data remains unvaried after the power failure.
When the DBCC CHECKDB command is executed on the database, the following error message is
received.
Object ID 2814307832,
index ID 2, partition ID 83127819437122157,
alloc unit ID 82134587923221126 (type In-row data): Page (3421:169) could not be processed.

Test (IS_OFF (BUF_IOERR, pBUF->bstat)) failed.
Values are 16928422 and -8.CHECKDB found 0 allocation errors and 2 consistency errors in table
'tbl_Customer' (object ID 2814307832).
When the sp_help 'tbl_customer' stored procedure is executed, the following result set is received:
index_name index_description
PK clustered located on PRIMARY NCIX nonclustered located on PRIMARY
Since you are the technical support, you are required to make sure that the data should be accessible in the shortest time. And the impact on users should be cut to the least.
Which action will you perform to finish the task?

A) To finish the task, the NCIX index should be dropped and recreated.
B) To finish the task, the latest full database backup should be recovered. And then, the latest differential backup should be recovered. At last, all transaction log backups should be recovered from the latest differential backup.
