Q51. HOTSPOT 

You are developing a SQL Server Integration Services (SSIS) package. The package contains a user-defined variable named @Queue which has an initial value of 10. 

The package control flow contains many tasks that must repeat execution until the @Queue variable equals 0. 

You need to enable the tasks to be grouped together for repeat execution. 

Which item should you add to the package? (To answer, select the appropriate item in the answer area.) 


Answer: 



Q52. HOTSPOT 

You are developing a SQL Server Integration Services (SSIS) package to implement an incremental data load strategy. The package reads rows from a source system and compares them to rows in a destination system. New rows will be inserted and changed rows will be updated. 

You have used a Lookup transformation and a Conditional Split transformation. The Lookup transformation joins the source and destination table on the business key, and includes all columns from the destination table in the data flow output. The Conditional Split transformation inspects the destination columns and directs data flow to either insert new records or update existing records. 

You need to configure the Lookup transformation to ensure that all records flow to the Conditional Split transformation, regardless of whether the rows match an existing row in the destination table. 

Which setting should you select? (To answer, select the appropriate option in the answer area.)

Q53. Note: This question is part of a series of questions that use the same or similar answer choices. An answer choice may be correct for more than one question in the series. Each question is independent of the other questions in this series. Information and details provided in a question apply only to that question. 

To ease the debugging of packages, you standardize the SQL Server Integration Services (SSIS) package logging methodology. 

The methodology has the following requirements: 

. Centralized logging in SQL Server 

Simple deployment 

Availability of log information through reports orT-SQL 

Automatic purge of older log entries 

Configurable log details 

You need to configure a logging methodology that meets the requirements while minimizing the amount of deployment and development effort. 

What should you do? 

A. Use the gacutil command. 

B. use the dtutil /copy command. 

C. use the Project Deployment Wizard. 

D. create an OnError event handler. 

E. create a reusable custom logging component. 

F. Run the package by using the dtexec /rep /conn command. 

G. Run the package by using the dtexec /dumperror /conn command. 

H. Run the package by using the dtexecui.exe utility and the SQL Log provider. 

I. Add a data tap on the output of a component in the package data flow. 

J. Deploy the package by using an msi file. 

K. Deploy the package to the Integration Services catalog by using dtutil and use SQL Server to store the configuration. 

Answer: C 


Q54. RAG DROP 

You administer a Microsoft SQL Server 2012 database. 

The database is backed up according to the following schedule: 

Daily full backup at 23:00 hours. 

Differential backups on the hour, except at 23:00 hours. 

Log backups every 10 minutes from the hour, except on the hour. 

The database uses the Full recovery model. 

A developer accidentally drops a number of tables and stored procedures from the database between 22:40 hours and 23:10 hours. You perform a database restore at 23:30 hours to recover the dropped table. 

You need to restore the database by using the minimum amount of administrative effort. You also need to ensure minimal data loss. 

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: 



Q55. You develop a SQL Server Integration Services (SSIS) package that imports Windows Azure SQL Database data into a data warehouse every night. 

The Windows Azure SQL Database data contains 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. Change the similarity threshold to 0.40. 

B. Decrease the maximum number of matches per lookup. 

C. Change the similarity threshold to 0.55. 

D. Change the Exhaustive property to True. 

Answer: C 

Explanation: The similarity thresholds can be set at the component and join levels. The join-level similarity threshold is only available when the transformation performs a fuzzy match between columns in the input and the reference table. The similarity range is 0 to 1. The closer to 1 the threshold is, the more similar the rows and columns must be to qualify as duplicates.

Q57. HOTSPOT 

You administer a Microsoft SQL Server 2012 database. 

The database contains a table that has the following definition: 


You want to export data from the table to a flat file by using the SQL Server Import and Export Wizard. 

You need to ensure that the following requirements are met: 

The first row of the file contains the first row of data. 

Each record is of the same length. 

The date follows the U.S. date format. 

The file supports international characters.

Q59. RAG DROP 

You administer a Microsoft SQL Server 2012 database. 

All database traffic to the SQL Server must be encrypted by using secure socket layer (SSL) certificates or the connection must be refused. 

Network administrators have deployed server certificates to the Windows store of all Windows servers on the network from a trusted Certificate Authority. This is the only Certificate Authority allowed to distribute certificates on the network. 

You enable the Force Encryption flag for the MSSQLServer protocols, but client computers are unable to connect. They receive the following error message: 

"A connection was successfully established with the server, but then an error occurred during the pre-login handshake, (provider: SSL Provider, error: 0 - The certificate chain was issued by an authority that is not trusted.) (Microsoft SQL Server)" 

You notice the following entry in the SQL Server log: 

"A self-generated certificate was successfully loaded for encryption." 

You need to configure SQL Server to encrypt all client traffic across the network. You also need to ensure that client computers are able to connect to the server by using a trusted certificate.
