NO.1 You are developing a SQL Server Integration Services (SSIS) package to implement an
incremental data load strategy. The package reads data from a source system that uses the SQL
Server change data capture (CDC) feature.
You have added a CDC Source component to the data flow to read changed data from the source
system.
You need to add a data flow transformation to redirect rows for separate processing of insert,
update, and delete operations.
Which data flow transformation should you use?
A. Pivot
B. Merge
C. Audit
D. CDC Splitter
Answer: B
Microsoft examen 70-458 examen certification 70-458 certification 70-458
Explanation:
MERGE with Incremental Loads The change data capture functionality that is new in SQL Server
2008 makes it easier to perform incremental loads reliably to a data warehouse. As an alternative to
using parameterized OLE DB Command transformations to perform the inserts and the updates, you
can use the MERGE statement to combine both operations.
NO.2 You are developing a SQL Server Integration Services (SSIS) package to load data into a data
warehouse. The package consists of several data flow tasks.
The package experiences intermittent errors in the data flow tasks.
If any data flow task fails, all package error information must be captured and written to a SQL
Server table by using an OLE DB connection manager.
You need to ensure that the package error information is captured and written to the table.
What should you do?
A. Use an event handler for OnError for the package.
B. Use an event handler for OnError for each data flow task.
C. Use an event handler for OnTaskFailed for the package.
D. View the job history for the SQL Server Agent job.
E. View the All Messages subsection of the All Executions report for the package.
F. Store the System::SourceID variable in the custom log table.
G. Store the System::ServerExecutionID variable in the custom log table.
H. Store the System::ExecutionInstanceGUID variable in the custom log table.
I. Enable the SSIS log provider for SQL Server for OnError in the package control flow.
J. Enable the SSIS log provider for SQL Server for OnTaskFailed in the package control flow.
K. Deploy the project by using dtutil.exe with the /COPY DTS option.
L. Deploy the project by using dtutil.exe with the /COPY SQL option.
M. Deploy the .ispac file by using the Integration Services Deployment Wizard.
N. Create a SQL Server Agent job to execute the SSISDB.catalog.validate_project stored procedure.
O. Create a SQL Server Agent job to execute the SSISDB.catalog.validate_package stored procedure.
P . Create a SQL Server Agent job to execute the SSISDB.catalog.create_execution and
SSISDB.catalog.*tart_execution stored procedures.
Q. Create a table to store error information. Create an error output on each data flow destination
that writes OnError event text to the table.
R. Create a table to store error information. Create an error output on each data flow destination
that writes OnTaskFailed event text to the table.

NO.3 DRAG DROP
You are building a fact table In a data warehouse.
The table must have a columnstore index. The table cannot be partitioned.
You need to design the fact table and load it with data.
Which three actions should you perform in sequence? (To answer, move the appropriate
actions from the list of actions to the answer area and arrange them in the correct order.)
Answer:
NO.4 You administer a Windows Azure SQL Database database named Inventory that contains a
stored procedure named p_AddInventory.
Users need to be able to SELECT from all tables in the database and execute the stored procedure.
You need to grant only the necessary permissions.
What should you do?
A. Add EXECUTE AS OWNER to the stored procedure. Add all users to the db_datareader role.
B. Add all users to the db_datawriter role. Add all users to the db_datareader role.
C. Create a new database role. Grant EXECUTE permission on p_AddInventory to the newrole. Add
all users to the role. Add all users to the db_datareader role.
D. Create a new database role. Grant EXECUTE permission on p_AddInventory to the new role.
Grant VIEW DEFINITION to to the role. Add all users to the role.
Answer: A

Explanation:
In SQL Server you can define the execution context of the following user-defined modules: functions
(except inline table-valued functions), procedures, queues, and triggers. By specifying the context in
which the module is executed, you can control which user account the Database Engine uses to
validate permissions on objects that are referenced by the module. This provides additional
flexibility and control in managing permissions across the object chain that exists between
user-defined modules and the objects referenced by those modules. Permissions must be granted to
users only on the module itself, without having to grant them explicit permissions on the referenced
objects. Only the user that the module is running as must have permissions on the objects accessed
by the module.
Reference: EXECUTE AS Clause (Transact-SQL) You administer a Microsoft SQL Server 2012 database.
NO.5 You are developing a SQL Server Integration Services (SSIS) project by using the Project
Deployment Model.
The project is deployed to a single SSIS catalog, and transfers data to and from multiple databases
hosted on SQL Server.
The project must be configured to be able to export data to and from five different production
servers that run SQL Server 2012. Each target server requires different values for connection strings
and parameters in the SSIS project.
You need to meet the requirements by using the least amount of administrative effort.
What should you do?
A. For each target server, create separate Environments in the SSIS catalog of the host SQL Server
SSIS instance. Select the appropriate Environment at package execution time.
B. Create one SSIS catalog Environment. Change the values of each Environment variable at package
execution time.
C. For each target server, create separate registry entry configurations. Select the registry entry at
package execution time.
D. For each target server, create a separate XML configuration file. Select the XML configuration file
at package execution time.

NO.6 ----
You administer a Microsoft SQL Server 2012 instance that contains a financial database hosted on a
storage area network (SAN).
The financial database has the following characteristics:
A data file of 2 terabytes is located on a dedicated LUN (drive D).
A transaction log of 10 GB is located on a dedicated LUN (drive E).
Drive D has 1 terabyte of free disk space.
Drive E has 5 GB of free disk space.
The database is continually modified by users during business hours from Monday through Friday
between 09:00 hours and 17:00 hours. Five percent of the existing data is modified each day.
The Finance department loads large CSV files into a number of tables each business day at 11:15
hours and 15:15 hours by using the BCP or BULK INSERT commands. Each data load adds 3 GB of
data to the database.
These data load operations must occur in the minimum amount of time.
A full database backup is performed every Sunday at 10:00 hours. Backup operations will be
performed every two hours (11:00, 13:00, 15:00, and 17:00) during business hours.
You need to ensure that your backup will continue if any invalid checksum is encountered.
Which backup option should you use?
A. Differential
B. Transaction log
C. FULL
D. SIMPLE
E. BULK_LOGGED
F. SKIP
G. RESTART
H. STANDBY
I. CHECKSUM
J. DBO_ONLY
K. COPY_ONLY
L. NORECOVERY
M. NO_CHECKSUM
N. CONTINUE_AFTER_ERROR
