第1题:

You are the administrator of a SQL server 2000 computer that contains a database named Acct. The database contains 1.5 GB of data. The server has one 9-GB hard disk that is configured as shown in the Exhibit.

You need to import data into the database without adversely affecting database performance. The data will require an additional 2GB of storage space.

What should you do?

A.Add another data file on drive E, and then add the file to the PRIMARY filegroup.

B.Move the transaction log file to drive E, and set the file growth of Acc_Data.mdf by selecting the Unrestricted file growth option.

C.Rebuild all clustered indexes so that they have a fill factor of 100.

D.Compress drive D.


正确答案:A
解析:Explanation: We must take precautions so that the import process of 2 GB data will run. We add a new file to drive E, which has 3 GB free disk space. By placing the new file in the primary file group we ensure that new data added to the database will be added to new data file. The primary file group is the default file group and new data is automatically added to it.

Incorrect Answers:
B: Moving the transaction log from Drive D to Drive would free up 800MB. This would leave 1.3GB of free disk space on drive D. But the import process will require another 2GB so we will not have enough free disk space.

C: Rebuilding the clustered indexes with a fill factor of 100 makes that the index pages full. This would degrade performance during the import process due to page splits.

D: Compressing a partition which is used by SQL Server is not a good idea. It would, if at all possible, degrade performance.

第2题:

Your production database is running in archivelog mode and you are using recovery manager (RMAN) with recovery catalog to perform the database backup at regular intervals.

The steps to recover the damaged data files are follows: 1. Mount the database 2. Open the database 3. Recover the data file 4. Restore the data file 5. Make the data file offline 6. Make the data file online Which option identifies the correct sequence that you must use to recover the data files?()

  • A、2, 4, 3
  • B、1, 4, 3, 2
  • C、2, 5, 4, 3, 6
  • D、5, 2, 4, 3, 6
  • E、1, 5, 4, 3, 6, 2

正确答案:E

第3题:

You are the administrator of a SQL Server 2000 computer. The server contains a Data Transformation Services (DTS) package that queries multiple databases and writes the results to a text file. You run this package by using a Microsoft Windows batch file. The batch file uses the dtsrun utility to execute the DTS package.

You want to ensure that connection properties, such as login names and passwords, cannot be read or modified by users. Which two actions should you take? (Each correct answer represents part of the solution. Choose two.)

A.Save the DTS package so that it has an owner password.

B.Save the DTS package so that it has a user password.

C.Encrypt the DTS package details in the command line of the dtsrun utility.

D.Store the DTS package in the Meta. Data Services repository.

E.Store the DTS package as a Microsoft Visual Basic file.


正确答案:AC
解析:Explanation: In this scenario we will use a windows batch file with the owner password for maximum security.

A: When running the Dtsrun utility on a package you must either specify a user password or a package password. Specify a password for the package to protect sensitive user name and server password information in the package from unauthorized users with owner password. If the package has an owner password, the data is encrypted with the standard encryption API. This protects protect sensitive user name and server password information in the package from unauthorized user.
.
C: You can encrypt the command prompt options to be executed by the DTS Run utility, allowing you to create an encrypted dtsrun command for later use. This will ensure that login names, password and other command line options cannot be read or modified by users.

Note: When a package is saved to SQL Server or as a structured storage file, DTS package passwords can be assigned to the package. These passwords are used in addition to the Windows Authentication or SQL Server Authentication passwords to connect to an instance of SQL Server.

There are two types of DTS package passwords that can be set: an owner password and a user password. If an owner password is set, the package user needs the password to edit or run the package and if a user password is set, the package users with access to the user password can run the package.

Incorrect Answers:
B: There is no need to create a user password. The package will be run with an owner password. The owner password will be protected since the command options are encrypted.

D: The Meta. Data Services repository is the storage container for the meta. data used by Analysis Services. Meta. data is stored in tables in a relational database and is used to define the parameters and properties of Analysis server objects. DTS package information can be saved to Meta. Data Services. This saves meta. data information about the databases referenced in the package, which can be viewed though the DTS Browser.

E: When a DTS package is saved as a Visual Basic file, these files can be used as templates, or starting points, for user-implemented Visual Basic packages. The generated code sets all properties of all objects referenced in the package to the initial values they will have when package execution begins. This includes those that are set to their default values.

第8题:

You are the administrator of a SQL Server 2000 computer. You are creating a data transformation services package. As the first step in this process, you need to load data from text files into a database table. These text files contain data on new stores that join your franchise. The text files list the data columns in the following format StoreID, StoreName, Address, City, State, PostalCode, ManagerID, StoreTypeID, FacilityID.

The destination table is configured as shown in the exhibit.

You want to load the data into the table as quickly as possible. What should you do?

A.Use a Bulk Insert Task to read the data into a temporary table. Use an Execute SQL task to import the appropriate data into the destination table.

B.Create and edit a format file to select the columns you want to import. Use a Bulk Insert Task, and then specify the format file to import the appropriate data into the destination table.

C.Use a transform. data task to import the data. Use Microsoft ActiveX transformation scripts to write the appropriate data to the appropriate columns in the destination table.

D.Create and edit a format file to select the columns you want to import. Use a transform. data task, and then specify the format file to import the appropriate data into the destination table.
