You are writing a SQL Server Integration Services (SSIS) package that transfers data from a legacy system.
Data integrity in the legacy system is very poor. Invalid rows are discarded by the package but must be logged to a CSV file for auditing purposes.
You need to establish the best technique to log these invalid rows while minimizing the amount of development effort.

You are deploying a new SQL Server Integration Services (SSIS) package to several servers.
The package must meet the following requirements:
- INET Common Language Runtime (CLR) integration in SQL Server must not be enabled. - The Connection Managers used in the package must be configurable without editing the package. - The deployment procedure must be automated as much as possible.
You need to set up a deployment strategy that meets the requirements.

You administer several Microsoft SQL Server 2012 servers. Your company has a number
of offices across the world connected by using a wide area network (WAN).
Connections between offices vary significantly in both bandwidth and reliability.
You need to identify the correct replication method for each scenario.
What should you do? (To answer, drag the appropriate replication method or methods to the correct location or locations in the answer area. Each replication method may be used once, more than once, or not at all.)

Correct Answer:
A SQL Server Integration Services (SSIS) 2012 package currently downloads sales data from a Windows Azure SQL Database database.
To improve sales data accuracy, exchange rates must be downloaded daily from a public HTTP web service instead of from a weekly flat file.
You need to implement the change to the existing package while minimizing the development effort.
What should you use to call the web service to retrieve the daily exchange rates?

You are designing a SQL Server Integration Services (SSIS) data flow to load sales transactions from a source system into a data warehouse hosted on Windows Azure SQL Database. One of the columns in the data source is named ProductCode.
Some of the data to be loaded will reference products that need special processing logic in the data flow.
You need to enable separate processing streams for a subset of rows based on the source product code.
Which Data Flow transformation should you use?

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.

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.

Explanation: Only visible for Pass4Leader members. You can sign-up / login (it's free).
You administer a Windows Azure SQL Database database named Human_Resources. The database contains 2 tables named Employees and SalaryDetails.
You add two Windows groups as logins for the server:
---
CORP\Employees - All company employees CORP\HRAdmins - HR administrators only HR Administrators are also company employees.
You need to grant users access according to the following requirements:
-
CORP\Employees should have SELECT access to the Employees table.
- Only users in CORP\HRAdmins should have SELECT access to the SalaryDetails table. - Logins are based only on Windows security groups.

You are designing a SQL Server Integration Services (SSIS) 2012 package that imports data from a Windows Azure SQL Database database into a SQL Server database.
The SSIS package has the following requirements:
Every night, a very large amount of data is imported into the staging database.
Package processing time must be minimized.
The package must run on its own dedicated server when it is deployed to
production.
Transaction log activity when data is imported must be minimized.
You need to design the package to meet the requirements.
