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?
You administer a SQL Server 2005 instance. The instance is configured to use the named pipes network communication protocol.
You plan to upgrade the instance to SQL Server 2008.
You need to ensure that the upgraded isntance can continue to use the named pipes network communication protocol. You also need to ensure that the server uses the most secure authentication method available.
Which authentication method should you use?
A. NTLM authentication
B. Kerberos authentication
C. SQL Server authentication
D. Mixed-mode authentication
You administer a SQL Server 2008 instance. Your company security policy is designed to prevent changes to the server to the server
configuration. You plan to use Policy-Based Management Framework to implement the security policy. You need to ensure that the policy is configured to meet the security requirement. What should you do?
A. Use a domain account for the SQLAgent service.
B. Use the Local Service account for the SQLAgent service.
C. Enable the nested triggers server configuration option.
D. Disable the nested triggers server configuration.
You administer a SQL Server 2008 infrastructure.
The infrastructure contains SQL Server 2008 servers across four sites. All sites are connected via a WAN link. All sites use the same database application.
Your company has the following business requirements:
* All sites maintain data related to their site.
* Each site has access to data related to other sites.
* In the event of any site failure, database activity is redirected to another site.
You need to implement a replication topology that meets the business requirements.
Which solution should you implement?
A. Snapshot replication
B. HTTP Merge replication
C. Peer-to-Peer replication
D. Transactional replication that uses updating subscriptions
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?
A. Symmetric key encryption
B. Asymmetric key encryption
C. Certificate-based encryption
D. Transparent data encryption
You administer SQL Server 2008 instances at three sites. All sites share a mission-critical database. The business requirements specify that users at each site must be able to perform the following tasks:
Access and modify data on all sites with minimal latency.
Minimize data loss in the event of a server failure.
You need to provide a high-availability solution that meets the business requirements. Which solution should you implement?
A. Failover clustering
B. Peer-to-Peer replication
C. Asynchronous database mirroring without a witness server
D. Log shipping to servers at two of the sites to provide read-only copies of data
You deploy a new database application to a SQL Server 2008 instance on a server that has 4 processor cores and 64 GB of RAM. The application uses partitioned tables.
During testing, deadlocks occasionally occur on queries that are attempting to read data.
You find out that the deadlocks are related to the table partitions. You need to ensure that the application executes without deadlocks for the read queries. You also need to ensure that dirty reads do not occur.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)
A. Disable partition-level lock escalation.
B. Move each partitioned table to its own filegroup.
C. Add additional database files to each partitioned table.
D. Move the clustered indexes for the partitioned tables to a separate filegroup.
You administer a SQL Server 2008 instance. You plan to design a high-availability solution by using database mirroring.
The current application includes programming logic that will retry transactions if a failover occurs.
You need to configure a strategy that will provide the minimum amount of latency for committed transactions.
What should you do?
A. Pause database mirroring.
B. Configure manual failover role switching.
C. Configure forced service role switching.
D. Configure automatic failover role switching.
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 PK index.
B. Drop and recreate the NCIX index.
C. Restore the latest full database backup. Restore all transaction log backups from the latest full
D. Restore the latest full database backup. Restore the latest differential backup. Restore all transaction
log backups from the latest differential backup.
You are a professional level SQL Sever 2008 Database Administrator.
A SQL Server 2008 instance at the New York central site is managed by you, and it is called Ins01. There is a sales team in your company, and their task is to finish purchase orders for customer requests. The sales team updates data regularly in a local database by utilizing their portable computers. When the central site is connected by portable computers, a database named Sales will be synchronized with the local database. A duplication model will be created to duplicate the local database to the Sales database.
The requirements listed below should be satisfied by the duplication model:
First, when the same data is updated by multiple users independently, there should be no data conflicts.
Secondly, sensitive data such as product price cannot be updated by the sales team.
Thirdly, the data should be synchronized by the sales team not only at scheduled times but also on demand.
The best model should be identified to have data duplicated, and you should be reduced the development efforts to the least.
Which action will you perform?
A. You should utilize snapshot duplication along with each portable computer that is set up as a subscriber.
B. You should utilize transactional duplication along with each portable computer that is set up as a publisher.
C. You should utilize merge duplication along with each portable computer that is set up as a subscriber.
D. You should utilize SQL Server Integration Services (SSIS) to promote the date modification and pull
updates to the Sales database along with the SSIS packages, on demand.
