QUESTION NO: 1
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.
You have a database named DB1 that has change data capture enabled.
A Microsoft SQL Server Integration Services (SSIS) job runs once weekly. The job loads changes from
DB1 to a data warehouse by querying the change data capture tables.
You remove the Integration Services job.
You need to stop tracking changes to the database. The solution must remove all the change data capture configurations from DB1.
Which stored procedure should you execute?
A. catalog.restore_project
B. sys.sp.cdc.changejob
C. sys.sp_cdc_enable_db
D. catalog.deploy_project
E. catalog.stop.operation
F. sys.sp_cdc_disable_db
G. sys.sp_cdc.stopJob
H. sys.sp.cdc.addjob
Answer: F
Explanation
sys.sp_cdc_disable_db disables change data capture for all tables in the database currently enabled.
All system objects related to change data capture, such as change tables, jobs, stored procedures and functions, are dropped.

D. dtutil.exe /SQL package1 /COPY OTS;c:\repository\package1.dtsx
Answer: B

QUESTION NO: 3
Note: This question is part of a series of questions that use the same scenario. For your convenience, the scenario is repeated in each question. Each question presents a different goal and answer choices, but the text of the scenario is exactly the same in each question in this series.
You have a Microsoft SQL Server data warehouse instance that supports several client applications.
The data warehouse includes the following tables: Dimension.SalesTerritory, Dimension.Customer,
Dimension.Date, Fact.Ticket, and Fact.Order. The Dimension.SalesTerritory and Dimension.Customer tables are frequently updated. The Fact.Order table is optimized for weekly reporting, but the company wants to change it daily. The Fact.Order table is loaded by using an ETL process. Indexes have been added to the table over time, but the presence of these indexes slows data loading.
All data in the data warehouse is stored on a shared SAN. All tables are in a database named DB1.
You have a second database named DB2 that contains copies of production data for a development environment. The data warehouse has grown and the cost of storage has increased. Data older than one year is accessed infrequently and is considered historical.
You have the following requirements:
* Implement table partitioning to improve the manageability of the data warehouse and to avoid the need to repopulate all transactional data each night. Use a partitioning strategy that is as granular as possible.
* - Partition the Fact.Order table and retain a total of seven years of data.
* - Partition the Fact.Ticket table and retain seven years of data. At the end of each month, the partition structure must apply a sliding window strategy to ensure that a new partition is available for the upcoming month, and that the oldest month of data is archived and removed.
* - Optimize data loading for the Dimension.SalesTerritory, Dimension.Customer, and Dimension.Date tables.
* - Incrementally load all tables in the database and ensure that all incremental changes are processed.
* - Maximize the performance during the data loading process for the Fact.Order partition.
* - Ensure that historical data remains online and available for querying.
* - Reduce ongoing storage costs while maintaining query performance for current data.
You are not permitted to make changes to the client applications.
You need to configure the Fact.Order table.
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:
Explanation
From scenario: Partition the Fact.Order table and retain a total of seven years of data. Maximize the performance during the data loading process for the Fact.Order partition.
Step 1: Create a partition function.
Using CREATE PARTITION FUNCTION is the first step in creating a partitioned table or index.
Step 2: Create a partition scheme based on the partition function.
To migrate SQL Server partition definitions to SQL Data Warehouse simply:
Step 3: Execute an ALTER TABLE command to specify the partition function.

QUESTION NO: 4
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.
You are implementing a Microsoft SQL Server data warehouse with a multi-dimensional data model.
You have a fact table that includes sales data for all products. The model includes a dimension named
Geography that stores all geographies. You create a dimension that has a foreign key and provides the ability to analyze sales by the following sales channels: Internet or retail store.
You need to update the data model to allow business users to analyze Internet sales by geography without changing the overall structure of the data model.
What should you do?
A. fact table
B. slowly changing dimension (SCD)
C. conformed dimension
D. non-additive measure
E. dimension table reference relationship
F. semi-additive measure
G. star schema
H. snowflake schema
Answer: B

QUESTION NO: 5
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.
You are a database administrator for an e-commerce company that runs an online store. The company has the databases described in the following table.
Each day, you publish a Microsoft Excel workbook that contains a list of product names and current prices to an external website. Suppliers update pricing information in the workbook. Each supplier saves the workbook with a unique name.
Each night, the Products table is deleted and refreshed from MDS by using a Microsoft SQL Server
Integration Services (SSIS) package. All files must be loaded in sequence.
You need to add a data flow in an SSIS package to perform the Excel files import in the data warehouse.
What should you use?
A. Sequential container
B. Union All transformation
C. Merge Join transformation
D. Lookup transformation
E. Foreach Loop container
F. Balanced Data Distributor transformation
G. Merge transformation
H. MERGE statement
Answer: D
Explanation
If you're familiar with SSIS and don't want to run the SQL Server Import and Export Wizard, create an
SSIS package that uses the Excel Source and the SQL Server Destination in the data flow.
