NEW QUESTION 266
You have a Microsoft Azure SQL Data Warehouse instance that must be available six months a day for reporting. You need to pause the compute resources when the instance is not being used.
Solution: You use the Azure portal.
Does the solution meet the goal?

A. Yes
B. No

Answer: A

NEW QUESTION 267
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:
  • You are not permitted to make changes to the client applications.
  • You need to optimize the storage for the data warehouse.
What change should you make?

A. Partition the Fact.Order table, and move historical data to new filegroups on lower-cost storage.
B. Create new tables on lower-cost storage, move the historical data to the new tables, and then shrink the database.
C. Remove the historical data from the database to leave available space for new data.
D. Move historical data to new tables on lower-cost storage.

Answer: A
Explanation:
  • Create the load staging table in the same filegroup as the partition you are loading.
  • Create the unload staging table in the same filegroup as the partition you are deleteing.
From scenario: Data older than one year is accessed infrequently and is considered historical.

NEW QUESTION 268
You have the following line-of-business solutions:
  • ERP System
  • Online WebStore
  • Partner Extranet
One or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog. You have an additional server that hosts SQL Server Integration Services (SSIS) and a data warehouse. You populate the data warehouse with data from each of the line-of-business solutions. The data warehouse does not store primary key values from the individual source tables. The database for each solution has a table named Products that stored product information. The Products table in each database uses a separate and unique key for product records. Each table shares a column named ReferenceNr between the databases. This column is used to create queries that involve more than once solution. You need to load data from the individual solutions into the data warehouse nightly. The following requirements must be met:
  • If a change is made to the ReferenceNr column in any of the sources, set the value of IsDisabled to True and create a new row in the Products table.
  • If a row is deleted in any of the sources, set the value of IsDisabled to True in the data warehouse.
Solution: Perform the following actions:
  • Enable the Change Tracking feature for the Products table in the three source databases.
  • Query the CHANGETABLE function from the sources for the deleted rows.
  • Set the IsDIsabled column to True on the data warehouse Products table for the listed rows.
Does the solution meet the goal?

A. Yes
B. No

Answer: B
Explanation:
We must check for updated rows, not just deleted rows.

NEW QUESTION 269

Explanation:
To pause a SQL Data Warehouse database, use any of these individual methods:
  • Pause compute with Azure portal
  • Pause compute with PowerShell
  • Pause compute with REST APIs
NEW QUESTION 271
You have the following line-of-business solutions:
  • ERP System
  • Online WebStore
  • Partner Extranet
One or more Microsoft SQL Server instances support each solution. Each solution has its own product catalog. You have an additional server that hosts SQL Server Integration Services (SSIS) and a data warehouse. You populate the data warehouse with data from each of the line-of-business solutions. The data warehouse does not store primary key values from the individual source tables. The database for each solution has a table named Products that stored product information. The Products table in each database uses a separate and unique key for product records. Each table shares a column named ReferenceNr between the databases. This column is used to create queries that involve more than once solution. You need to load data from the individual solutions into the data warehouse nightly. The following requirements must be met:
  • If a change is made to the ReferenceNr column in any of the sources, set the value of IsDisabled to True and create a new row in the Products table.
  • If a row is deleted in any of the sources, set the value of IsDisabled to True in the data warehouse.
Solution: Perform the following actions:
  • Enable the Change Tracking for the Product table in the source databases.
  • Query the CHANGETABLE function from the sources for the updated rows.
  • Set the IsDisabled column to True for the listed rows that have the old ReferenceNr value.
  • Create a new row in the data warehouse Products table with the new ReferenceNr value.
Does the solution meet the goal?

......

NEW QUESTION 273
You have a data quality project that focuses on the Products catalog for the company. The data includes a product reference number. The product reference should use the following format:
  • Two letters followed by an asterisk and then four or five numbers. An example of a valid number is XX*55522.
  • Any reference number that does not conform to the format must be rejected during the data cleansing.
You need to add a Data Quality Services (DQS) domain rule in the Products domain. Which rule should you use?

A. value matches pattern ZA*9876[5]
B. value matches pattern AZ[*]1234[5]
C. value matches regular expression AZ[*]1234[5]
D. value matches pattern [a-zA-Z][a-zA-Z]*[0-9][0-9][0-9][0-9][0-9]

Answer: A
Explanation:
For a pattern matching rule:
  • Any letter (A...Z) can be used as a pattern for any letter; case insensitive
  • Any digit (0...9) can be used as a pattern for any digit
  • Any special character, except a letter or a digit, can be used as a pattern for itself
  • Brackets, [], define optional matching
This rule implies that the data will contain three parts: any three letters followed by a colon, which is again followed by any four digits.

NEW QUESTION 274

NEW QUESTION 295
You plan to deploy a Microsoft SQL server that will host a data warehouse named DB1. The server will contain four SATA drives configured as a RAID 10 array. You need to minimize write contention on the transaction log when data is being loaded to the database.
Solution: You replace the SATA disks with SSD disks.
Does this meet the goal?

A. Yes
B. No

Answer: B
Explanation:
A data warehouse is too big to store on an SSD. Instead you should place the log file on a separate drive.

NEW QUESTION 296
You plan to deploy a Microsoft SQL server that will host a data warehouse named DB1. The server will contain four SATA drives configured as a RAID 10 array. You need to minimize write contention on the transaction log when data is being loaded to the database.
Solution: You add more data files to DB1.
Does this meet the goal?

A. Yes
B. No

Answer: B
Explanation:
There is no performance gain, in terms of log throughput, from multiple log files. SQL Server does not write log records in parallel to multiple log files. Instead you should place the log file on a separate drive.

NEW QUESTION 297
You plan to deploy a Microsoft SQL server that will host a data warehouse named DB1. The server will contain four SATA drives configured as a RAID 10 array. You need to minimize write contention on the transaction log when data is being loaded to the database.
Solution: You configure the server to automatically delete the transaction logs nightly.
Does this meet the goal?

A. Yes
B. No

Answer: B
Explanation:
You should place the log file on a separate drive.

NEW QUESTION 298
You have a Microsoft SQL server that has Data Quality Services (DQS) installed. You need to review the completeness and the uniqueness of the data stored in the matching policy.
Solution: You profile the data.
Does this meet the goal?

A. Yes
B. No

Answer: B
Explanation:
Use a matching rule.

NEW QUESTION 299
You have a Microsoft SQL server that has Data Quality Services (DQS) installed. You need to review the completeness and the uniqueness of the data stored in the matching policy.
Solution: You create a matching rule.
Does this meet the goal?

A. Yes
B. No

Answer: B
Explanation:
Use a matching rule, and use completeness and uniqueness data to determine what weight to give a field in the matching process. If there is a high level of uniqueness in a field, using the field in a matching policy can decrease the matching results, so you may want to set the weight for that field to a relatively small value. If you have a low level of uniqueness for a column, but low completeness, you may not want to include a domain for that column.

NEW QUESTION 300
You have a Microsoft SQL server that has Data Quality Services (DQS) installed. You need to review the completeness and the uniqueness of the data stored in the matching policy.
Solution: You modify the weight of the domain in the matching rule.
Does this meet the goal?

A. Yes
B. No

Answer: A
Explanation:
Use a matching rule, and use completeness and uniqueness data to determine what weight to give a field in the matching process. If there is a high level of uniqueness in a field, using the field in a matching policy can decrease the matching results, so you may want to set the weight for that field to a relatively small value. If you have a low level of uniqueness for a column, but low completeness, you may not want to include a domain for that column.

NEW QUESTION 301
You have a server that has Data Quality Services (DQS) installed. You create a matching policy that contains one matching rule. You need to configure the Similarity of Similar percentage that defines a match. Which similarity percentage will always generate a similarity score of 0?

A. 55
B. 80
C. 70
D. 75

Answer: A
Explanation:
The minimum similarity between the values of a field is 60%. If the calculated matching score for a field of two records is less than 60, the similarity score is automatically set to 0.

NEW QUESTION 302
You need to ensure that a downstream system can consume data in a Master Data Services (MDS) system. What should you configure?

A. a Data Collector
B. a knowledge base
C. a matching policy
D. a subscription view

Answer: D
Explanation:
Subscription views to consume your master data.

NEW QUESTION 303

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.deploy_project
B. catalog.restore_project
C. catalog.stop_operation
D. sys.sp_cdc_add_job
E. sys.sp_cdc_change_job
F. sys.sp_cdc_disable_db
G. sys.sp_cdc_enable_db
H. sys.sp_cdc_stop_job

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.

NEW QUESTION 304
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. Users report that an application that uses DB1 is suddenly unresponsive. You discover that the Integration Services job causes severe blocking issues in the application. You need to ensure that the users can run the application as quickly as possible. Your SQL Server login is a member of only the ssis_admin database role. Which stored procedure should you execute?

A. catalog.deploy_project
B. catalog.restore_project
C. catalog.stop_operation
D. sys.sp_cdc_add_job
E. sys.sp_cdc_change_job
F. sys.sp_cdc_disable_db
G. sys.sp_cdc_enable_db
