第2题：
You are the administrator of two Microsoft Windows 2000 advanced server computers. On these servers, you are configuring a database that will store accounting information for your company.
The data must be available at all times. Interruptions in data connectivity should not last longer than five minutes. Any changes to the database should not require you to reconfigure the client computers.
How should you configure the database?
A．Configure the database on the two servers as a SQL Server 2000 cluster.
B．Configure the database on one server, and then configure a standby database on the second server.
C．Configure the database on each server. Use Microsoft Distributed Transaction Coordinator to keep the two servers perfectly synchronized.
D．Configure the database as a federated database, and then partition half the data on each server.
正确答案：A
解析：Explanation: SQL Server 2000 failover clustering provides high availability support by allowing us to configure one failover cluster to automatically, with no manual configuration, fail over to any other node in the failover cluster configuration. In this way, we minimize system downtime and provide high server availability during an operating system failure or a planned upgrade. Before SQL Server 2000 failover clustering can be set up, we must install Windows NT 4.0, Enterprise Edition, Windows 2000 Advanced Server or Windows 2000 Datacenter Server, and the Microsoft Cluster Service (MSCS).
In this scenario a cluster would be preferred to a standby server because it would be available immediately. A standby server on the other would require manual configuration and more time to become online.
Incorrect Answers:
B: A standby server would require you to reconfigure clients to allow it to connect to the standby server when the main server goes down. It would require at least several minutes of manual administration before the standby server would be operational. But the scenario requires that no reconfiguration of the client computers should be necessary. Therefore we should use a SQL Server 2000 cluster not a standby server.
Note: A standby server is a second server that contains a copy of the databases on the primary server and that can be brought online in the event of a primary server failure or due to scheduled maintenance on the primary server. This allows users to continue working with databases when the primary server becomes unavailable. When the primary server becomes available again, any changes to the standby server's copies of databases must be restored back to the primary server.
C: The Microsoft Distributed Transaction Coordinator coordinates distributed transactions, but would not increase availability.
Note: The Microsoft Distributed Transaction Coordinator (MS DTC) is a transaction manager that allows client applications to include several different sources of data in one transaction. MS DTC coordinates committing the distributed transaction across all the servers enlisted in the transaction.
An installation of SQL Server 2000 can participate in a distributed transaction by calling stored procedures on remote servers running SQL Server, automatically or explicitly promoting the local transaction to a distributed transaction and enlist remote servers in the transaction, and making distributed updates that update data on multiple OLE DB data sources. If these OLE DB data sources support the OLE DB distributed transaction interface, SQL Server 2000 can also enlist them in the distributed transaction. The MS DTC service coordinates the proper completion of the distributed transaction to ensure that either all of the updates on all the servers are made permanent, or, in the case of errors, all erased.
D: With Federated SQL Server 2000 servers, SQL Server 2000 databases can be spread across a group of autonomous database servers. These are capable of supporting the processing growth requirements of the largest Web sites and enterprise data-processing systems built with Microsoft Windows DNA, which divides the processing units of a data processing system into logical tiers. This however does not improve availability.

第3题：
You are the administrator of a SQL Server 2000 computer. The server contains a database named Acct. You purge the Acct database of old records and perform. a full backup. The database now uses 4 GB of space. The database files are configured as shown in the Acct Properties exhibit.
The server has two hard disks that are configured as shown in the Server Configuration exhibit.
The 3 GB transaction log file for the Acct database is stored on drive C. You need to make room for a new database that has a 3 GB data file and a 1 GB transaction log file. You want to optimize database performance on both databases. You also want to minimize administrative overhead.
What should you do?
A．Shrink the empty data file on drive E. Place the new data file and the new log file on drive E.
B．Shrink the empty data file on drive E. Backup and shrink the log file on drive C to 2 GB. Place the new data file on drive E and the new log file on drive C.
C．Shrink the data file on drive D to 1 GB, and then shrink the data file on drive E to 2 GB. Place the new data file on drive D and the new log file on drive E.
D．Shrink and delete the data file on drive C, and then shrink the database files on drives D and E so that they are both 2 GB. Place the new data file and the new log file on drive C.
正确答案：B
解析：Explanation: We must add a new 3GB database with a 1GB transaction log file. Currently we have database that is using 4GB for data and 3GB for the log file. We should place the log file and the data file on two different physical disks out of performance reasons.
The command DBCC SHRINKFILE with the EMPTYFILE option can be used to shrink a datafile to empty. The data will be migrated to the other files in the filegroup. We use this method to free 4.5 GB on Drive E. Then we backup the log file on C and reduce it to 2GB. Then we put the database data file on drive (3GB) and put the log file of the new database on drive C (1GB).
Incorrect answers:
A: It’s better to put the data file and the log file of the new database on two different physical disks out of performance reasons.
C: It’s better to put the data file and the log file of the new database on two different physical disks out of performance reasons.
D: It’s better to put the data file and the log file of the new database on two different physical disks out of performance reasons.

You are the administrator of a SQL Server 2000 computer. Your company uses the server to store service contract information for its customers.
You are also the administrator of Oracle relational database management system (RDBMS) server.
This server is used to store your company’s financial information. The financial information is updated frequently throughout the day.
You need to create a series of reports that combine the service contract information and the financial information. These reports will be updated several times a day.
You want to create reports on the SQL Server computer by using the minimum amount of disk space.
What should you do?
A．Set up SQL server replication to replicate the data from the oracle server to the SQL server computer.
B．Set up the oracle server as a linked server. Create a view that joins the service contract information and the financial information.
C．Set up data transformation services (DTS) package that imports and transforms the database from the oracle server to the SQL server computer. Use SQL server agent to execute the DTS package throughout the day as needed.
D．Set up Microsoft ActiveX script. that connects to the oracle server and imports the financial information into SQL server temporary table. Create a view that joins the service contract information and the temporary table.
正确答案：B
解析：Explanation: SQL Server 2000 permits the creation of links to OLE DB data sources called linked servers. After linking to an OLE DB data source, it is possible to reference rowsets from the OLE DB data sources as tables in Transact-SQL statements and to pass commands to the OLE DB data sources and include the resulting rowsets as tables in Transact-SQL statements.
Each distributed query can reference multiple linked servers and can perform. either update or read operations against each individual linked server. A single distributed query can perform. read operations against some linked servers and update operations against other linked servers. The Microsoft OLE DB Provider for Oracle allows distributed queries to query data in Oracle databases.
Incorrect Answers:
A: Replication allows for the coping, distribution, and modification of data across an enterprise. This involves the copying of database data from one server to another. This is not the best solution in this scenario as this will require frequent replication because the reports must be updated several times a day.
C: Data Transformation Services is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.
D: Microsoft ActiveX scripts can be used to add functionality to Data Transformation Services packages, which is a set of graphical tools and programmable objects that allows for the extraction, transformation, and consolidation of data from disparate sources into single or multiple destinations. In this scenario, however, the Oracle database needs to be included in a query. Hence, Data Transformation Services are inappropriate.

第15题：
You are the administrator of a SQL Server 2000 computer. Your company purchased an accounting application from a vendor. The application stores its data in a database named Accounting on the server. The tables in this database contain columns that function as primary keys, but PRIMARY KEY and FOREIGN KEY constraints are not used.
You need to replicate data from this database to another SQL Server computer. This server will use the replicated data to generate reports. Most reports will run each month, but the accounting department needs to have the ability to run reports at any time. Reports should be accurate through the last full working day.
You cannot make any changes to the database, but you need to implement replication. Which two actions should you take? (Each correct answer presents part of the solution. Choose two)
A．Implement merge replication.
B．Implement snapshot replication.
C．Implement transactional replication.
D．Schedule replication to run continuously.
E．Schedule replication to run during off-peak hours.
正确答案：BE
解析：Explanation:
B: Snapshot replication is the best solution since we will not be making changes to the Accounting database but need to replicate data from the database to another SQL Server computer and as the accounting department needs to have the ability to run reports that only need to be accurate through the last full working day.
E: Only one snap-shot replication would be necessary per day, and to make as little impact on the daily use of the server this replication should be scheduled during off-peak hours.
Note: SQL Server 2000 provides three types of replication that can be used in distributed applications. These are snapshot replication, transactional replication and merge replication. Each type provides different capabilities.
Snapshot replication is the process of copying and distributing data and database objects exactly as they were at the time the snapshot was taken. Snapshot replication does not require continuous monitoring of changes because changes made to published data are not propagated to the Subscriber incrementally. Subscribers are updated with a complete data set and not individual transactions. As snapshot replication replicates an entire data set at one time, it may take longer to propagate data modifications to Subscribers. This type of replication in helpful in situations when data is mostly static and does not change often; it is acceptable to have copies of data that are out of date for a period of time; replicating small volumes of data; and when sites are often disconnected and high latency (the amount of time between when data is updated at one site and when it is updated at another) is acceptable.
In transactional replication, an initial snapshot of data is propagated to Subscribers, and then when data modifications are made at the Publisher, the individual transactions are captured and propagated to Subscribers. SQL Server 2000 monitors INSERT, UPDATE, and DELETE statements, and changes to stored procedure executions and indexed views. SQL Server 2000 stores the transactions affecting replicated objects and then it propagates those changes to Subscribers continuously or at scheduled intervals. Transaction boundaries are preserved. Transactional replication is used when data modifications must be propagated to Subscribers, often as they occur; transactions must be atomic; subscribers are mostly connected to the Publisher and when the application will not tolerate high latency for Subscribers receiving changes.
Merge replication allows various sites to work autonomously and merge data modifications made at multiple sites into a single, uniform. result at a later time. The initial snapshot is applied to Subscribers and then SQL Server 2000 tracks changes to published data at the Publisher and at the Subscribers. The data is synchronized between servers either at a scheduled time or on demand. Updates are made independently at more than one server, so the same data may have been updated by the Publisher or by more than one Subscriber. Therefore, conflicts can occur when data modifications are merged. This type of replication is helpful when multiple Subscribers need to update data at various times and propagate those changes to the Publisher and to other Subscribers; Subscribers need to receive data, make changes offline, and synchronize changes later with the Publisher and other Subscribers; the application latency requirement is either high or low, and when site autonomy is critical.
Incorrect Answers:
A: No data at the second server will not be changed so there is no need to use merge replication.
C: We don’t need the accuracy of transactional replication. In this scenario high latency is permissible as the reports must be accurate only through the last full working day.
Note: Transactional replication is used when data modifications must be propagated to Subscribers, often as they occur; transactions must be atomic; subscribers are mostly connected to the Publisher and when the application will not tolerate high latency for Subscribers receiving changes.
D: As the reports must be accurate through the last full working day, it not necessary to run replication continuously. Running replication continuously will place locks on the destination database, which would hamper the performance of queries and actions run against the destination database.
