Trang 1break the linked server you created for secured access to Oracle Answer D
is incorrect because you already have linked server, and while linked servers
provide an alternative to distributed ad hoc distributed, they don’t prevent
distributed ad hoc queries
9 You need to write a query that joins data from your local SQL Server Instance with data from an Oracle instance You need to be able to submit specific syntax to the Oracle instance to get the correct results by using a pass-through query No linked servers currently exist for the remote Oracle instance You are not an administrator on the system Which one of the following choices meets your needs?
A Use OPENQUERY( )
B Use OPENDATASOURCE( )
C Use OPENROWSET( )
D Create a Linked Server
Correct Answer and Explanation: C Answer C is correct
becauseOPEN-ROWSET( ) allows you to submit pass-through queries to a remote system, and it does not require that you be an administrator as long as an administrator has allowed ad hoc distributed queries and enabled the required provider for
ad hoc access
Incorrect Answers and Explanations: A, B, and D Answer A is incorrect
because OPENQUERY requires that you have a linked server definition in
order to use it Answer B is incorrect because the OPENDATASOURCE( ) function does not support pass-through queries Answer D is incorrect because
you are not an administrator, and don’t have the privilege to create linked servers on the SQL Server instance
10 You need to provide support for distributed queries to a remote SQL Server instance, but you need to allow it only for selected users Which one of the following solutions meets the requirements?
A Grant execute permissions on the OPENROWSET function to the
selected users
B Create a linked server and assign the selected users credentials to use when connecting to the remote instance
C Enable the “disallow adhoc access” on the SQL Server OLE DB to prevent
ad hoc access
Trang 2D Use sp_configure to set the “Ad Hoc Distributed Queries” to 1
Correct Answer and Explanation: B Answer B is correct because Linked
servers allow you to create specific login details for individual users to remote
databases
Incorrect Answers and Explanations: A, C, and D Answer A is incorrect because
you can not grant specific permissions to system functions OPENROWSET
is a system function Answer C is incorrect because disallowing ad hoc access
on the provider would affect all users, not just specific users Answer D is
incorrect because it allows all users, not just specific users, to perform distributed
ad hoc queries
11 Developers complain that they are receiving errors when trying to perform ad
hoc distributed queries against Oracle, although they are able to run distributed
ad hoc queries against SQL Server What must you do to solve the problem?
A Install the Oracle client libraries on the developer workstations
B Use sp_configure to set the “Ad Hoc Distributed Queries” to 1
C Enable the “disallow adhoc access” property on the Oracle OLE DB provider
D Disable the “disallow adhoc access” property on the Oracle OLE DB provider
Correct Answer and Explanation: D Answer D is correct Because developers
can run ad hoc queries against other database engines, the problem must be
specifically with the Oracle provider Disabling the “disallow adhoc access”
property on the Oracle provider would solve the problem
Incorrect Answers and Explanations: A, B, and C Answer A is incorrect
because distributed queries rely on the providers available on the server, not on
the client workstations Answer B is incorrect because developers can already
run ad hoc queries against other SQL Servers The option must already be
turned on for the query to be true Answer C is incorrect because enabling the
“disallow adhoc access” property on the provider actually prevents its use in ad
hoc queries
12 You need to transfer a database to another server for testing purposes You
want to ensure that you get the entire database as well as any logins and SQL
Server Agent Jobs related to the database You want to perform the transfer as
easily as possible Which one of the following tools best meets your needs?
A Import and Export Wizard
B Copy Database Wizard
Trang 3C Business Intelligence Development Studio
D BCP
Correct Answer and Explanation: B Answer B is correct because the Copy
Database wizard makes it easy to transfer an entire database, as well as
environmental values like Logins and SQL Server Agent jobs between two instances of SQL Server
Incorrect Answers and Explanations: A, C, and D Answer A is incorrect
Although you could use the Import and Export Wizard to transfer each and every table in the source database, you would not be able to transfer the other database objects like stored procedures and functions, nor the metadata Answer
C is incorrect because it isn’t the easiest way to accomplish the task BIDS does
make it possible to create packages that meet our needs, but it would involve much more effort to create and deploy the package than is required by the
Copy Database Wizard Answer D is incorrect because BCP could help move
only the data itself, not the object definitions and metadata, nor the external objects like logins and SQL Server Agent Jobs
13 You need to import data from an Access database into a database in SQL Server You want to perform the import as simply as possible Which one of the following options best meets the requirements?
A Import and Export Wizard
B Copy Database Wizard
C Business Intelligence Development Studio
D BCP
Correct Answer and Explanation: A Answer A is correct The Import and
Export Wizard makes it simple to directly export data from an Access database and import it into SQL Server
Incorrect Answers and Explanations: B, C, and D Answer B is incorrect
because it requires the source and destination both be SQL Server Answer C
is incorrect because while BIDS would allows us to create a package that meets our needs, it would not be as simple as the Import and Export Wizard
Answer D is incorrect because BCP import from flat files into SQL Server.
14 You need to deploy an SSIS package to a production server You want to use package roles to control access to the packages When the developer creates the package, which protection level should they use?
Trang 4A Encrypt sensitive with password
B Encrypt all with user key
C Rely on server storage and roles for access control
D Encrypt all with password
Correct Answer and Explanation: C Answer C is correct To use the package
roles, the package must be stored in the MSDB database, and be saved with the
“Rely on server storage and roles for access control” protection level
Incorrect Answers and Explanations: A, B, and D Answers A, B and D rely
on passwords or a key unique to the package creator for access rather than
package roles
15 Your company implements formal development, test, and production
environ-ments Packages are using servers in the development environment, tested on
servers in the test environment, and finally run in the production environment You need to point the packages to the correct servers depending on the
envi-ronment without having to edit the packages themselves Which of the
fol-lowing options best supports changing the properties of a package at runtime?
A Package Configurations
B DTExec command line options
C “SQL Server Integrations Services Packages” step in a job
D DTExecUI options
Correct Answer and Explanation: A Answer A is correct Package
Configurations make it possible to store the various properties needed in the
different environments in XML files, SQL tables or other locations Package
configurations can be assigned at run-time to easily change the properties of
a package
Incorrect Answers and Explanations: B, C, and D Answers B, C and D all use
the same runtime to run a package While you can use the options of the
commands to manually set properties of packages when you run them, it is
much more difficult and repetitive than using package configurations
16 You receive a data file each day from a business partner You need to import
the file each morning after it is received Your developers have created a
package to properly import the file, and have deployed the package to your
SSIS instance When they saved the package, they used the “Encrypt all with
Trang 5Password” protection level You need to make sure the password can’t be seen
in the scheduled job’s definition What should you do to schedule the package?
A Create a SQL Server Agent job and use an “Operating System (cmdExec)” step to run the DTExec utility
B Create a SQL Server Agent job and use a “SQL Server Integration Services Package” step
C Use the “Scheduled Tasks” in windows to run the DTExec utility nightly
D Use the “Scheduled Tasks” in windows to run the DTExecUI utility nightly
Correct Answer and Explanation: B Answer B is correct By using the
SQL Server Integration Services Package job step, we can securely enter the password needed to open the package, and prevent it from being stored in clear text
Incorrect Answers and Explanations: A, C, and D Answer A is incorrect
because the password to access the package would be easily viewed by anybody
who could read the jobs definition Answer C is incorrect because it too
would allow the passwords to be seen by anybody that could read the scheduled
task’s definition Answer D is incorrect because the DTExecUI uses a GUI
You should not schedule GUI programs that require user input
17 You are a sysadmin on your SQL Server instance You are trying to manage the package roles on the “Export Product Data” package shown in Figure 8.8, but receive an error What must you do to allow the package roles to be used?
A Use the “Encrypt all with user key” protection level
B Use the “Encrypt all with password” protection level
C Save the package to the MSDB database rather than the file system
