QUESTION 71

DRAG DROP

You are developing a SQL Server Integration Services (SSIS) package that imports unsorted data

into a data warehouse hosted on SQL Azure. You have the following requirements:

 

Ÿ   A destination table must contain all of the data in two source tables.

Ÿ   Duplicate records must be inserted into the destination table.

 

You need to develop a data flow that imports the data while meeting the requirements. How

should you develop the data flow?

 

To answer, drag the appropriate transformation from the list of transformations to the correct

location in the answer area.

QUESTION 72

You are creating a SQL Server Master Data Services (MDS) mode). This model is used to store a

master list of products. An attribute must be added to the Product entity to define the sales

manager responsible for each product. You need to create an attribute in the Product entity that

prevents users from entering invalid sales manager values. Which type of attribute should you

create?

 

A.     Derived

B.     Domain-based

C.     User-defined

D.     Parent

E.      Explicit

F.      Recursive

 

Correct Answer: B

 

 

QUESTION 73

You develop a SQL Server Integration Services (SSIS) package that imports SQL Azure data into a

data warehouse every night. The SQL Azure data con
tains many misspellings and variations of

abbreviations. To import the data, a developer used the Fuzzy Lookup transformation to choose

the closest-matching string from a reference table of allowed values. The number of rows in the

reference table is very large. If no acceptable match is found, the Fuzzy Lookup transformation

passes a null value. The current setting for the Fuzzy Lookup similarity threshold is 0.50. Many

values are incorrectly matched. You need to ensure that more accurate matches are made by the

Fuzzy Lookup transformation without degrading performance. What should you do?

 

A.       Decrease the maximum number of matches per lookup.

B.       Change the similarity threshold to 0.55.

C.       Change the Exhaustive property to True.

D.       Increase the maximum number of matches per lookup.

QUESTION 74

You are designing a data warehouse hosted on SQL Azure. The data warehouse currently includes

the dimllser and dimDistrict dimension tables and the factSales fact table. The dimUser table

contains records for each user permitted to run reports against the warehouse, and the

dimDistrict table contains information about sales districts. The system is accessed by users from

certain districts, as well as by area supervisors and users from the corporate headquarters. You

need to design a table structure to ensure that certain users can see sales data for only certain

districts. Some users must be permitted to see sales data from multiple districts. What should

you do?

 

A.       Create a userDistrict table that contains primary key columns from the dimUser and

dimDistrict tables.

B.       Partition the factSales table on the district column.

C.       Add a district column to the dimUser table.

D.       For each district, create a view of the factSales table that includes a WHERE clause for the

district.

QUESTION 75

DRAG DROP

You are creating a sales data warehouse. When a product exists in the product dimension, you

update the product name. When a product does not exist, you insert a new record. In the current

implementation, the DimProduct table must be scanned twice, once for the insert and again for

the update. As a result, inserts and updates to the DimProduct table take longer than expected.

You need to create a solution that uses a single command to perform an update and an insert.

How should you use a MERGE T-SQL statement to accomplish this goal?

 

To answer, drag the appropriate answer choice from the list of options to the correct location or

locations in the answer area. You may need to drag the split bar between panes or scroll to view

content.

QUESTION 76

You develop three Microsoft SQL Server 2012 databases named Database1, Database2, and

Database3. You have permissions on both Database1 and Database2. You plan to write and

deploy a stored procedure named dbo.usp_InsertEvent in Database3. dbo.usp_InsertEvent must

execute other stored procedures in the other databases. You need to ensure that callers that do

not have permissions on Database1 or Database2 can execute the stored procedure. Which

Transact-SQL statement should you use?

 

A.     USE Database2

B.     EXECUTE AS OWNER

C.     USE Database1

D.     EXECUTE AS CALLER

 

Correct Answer: B

 

 

 

 

 

 

 

 

 

QUESTION 77

DRAG DROP

You administer three Microsoft SQL Server 2012 servers named ServerA, ServerB, and ServerC.

ServerA is the acting principal and ServerB is the mirror. You need to add ServerC as a witness to

the existing mirroring session between ServerA and ServerB. You need to achieve this goal

without delaying synchronization. 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.

QUESTION 78

DRAG DROP

You administer three Microsoft SQL Server 2008 R2 instances. Database mirroring is configured

in High-Safety mode with Automatic Failover between the following three servers:

 

Ÿ   SQL1 is the Principal server.

Ÿ   SQL2 is the mirror server.

Ÿ   SQL3 is the witness server.

 

You need to upgrade SQL1 and SQL2 to SQL Server 2012. You need to ensure that downtime is

minimized during the upgrade. Which six 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.

QUESTION 79

You admi
nister a Microsoft SQL Server 2012 failover cluster that contains two nodes named Node

A and Node B. A single instance of SQL Server is installed on the cluster. An additional node

named Node C has been added to the existing cluster. You need to ensure that the SQL Server

instance can use all nodes of the cluster. What should you do?

 

A.     Create a ConfigurationFile.ini file from Node B, and then run the AddNode command-line

tool on Node A.

B.     Use Node A to install SQL Server on Node C.

C.     Run the Add Node to SQL Server Failover Cluster Wizard on Node C.

D.     Use Cluster Administrator to add a new Resource Group to Node B.

 

Correct Answer: C

 

 

QUESTION 80

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:

 

Ÿ   A data file of 2 terabytes is located on a dedicated LUN (drive D).

Ÿ   A transaction log of 10 GB is located on a dedicated LUN (drive E).

Ÿ   Drive D has 1 terabyte of free disk space.

Ÿ   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 the minimum amount of data is lost. Which recovery model should the database

use?

 

A.       FULL

B.       DBO_ONLY

C.       CONTINUE_AFTER_ERROR

D.       CHECKSUM

E.       NO_CHECKSUM

F.        SIMPLE

G.       Transaction log

H.       SKIP

I.         RESTART

J.        COPY_ONLY

K.       NORECOVERY

L.        BULK_LOGGED

M.     Differential

N.      STANDBY
