NEW QUESTION 1
You deploy a Microsoft Azure SQL Data Warehouse instance. The instance must be available eight hours each day.
You need to pause Azure resources when they are not in use to reduce costs.
What will be the impact of pausing resources? To answer, select the appropriate options in the answer area. NOTE: Each correct selection is worth one point.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
To save costs, you can pause and resume compute resources on-demand. For example, if you won't be using the database during the night and on weekends, you can pause it during those times, and resume it during the day. You won't be charged for DWUs while the database is paused.
When you pause a database:
Compute and memory resources are returned to the pool of available resources in the data center Data Warehouse Unit (DWU) costs are zero for the duration of the pause.
Data storage is not affected and your data stays intact.
SQL Data Warehouse cancels all running or queued operations. When you resume a database:
SQL Data Warehouse acquires compute and memory resources for your DWU setting. Compute charges for your DWUs resume.
Your data will be available.
You will need to restart your workload queries. References:

NEW QUESTION 2
Note: This question is part of a series of questions that present the same scenario. Each question in the series contains a unique solution that might meet the stated goals. Some question sets might have more than one correct solution, while others might not have a correct solution.
After you answer a question in this sections, you will NOT be able to return to it. As a result, these questions will not appear in the review screen.
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.

When users enter data, they do not consistently apply the correct names for the sports. The following table shows examples of the data entry issues.

You need to improve the quality of the data.
Which four 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.

NEW QUESTION 6
You administer a Microsoft SQL Server Master Data Services (MDS) model. All model entity members have passed validation.
The current model version should be committed to form a record of master data that can be audited and create a new version to allow the ongoing management of the master data.
You lock the current version. You need to manage the model versions.
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.

• A. Mastered
• B. Not Mastered

Answer: A

Explanation:
Box 1: Validate the current version.
In Master Data Services, validate a version to apply business rules to all members in the model version. You can validate a version after it has been locked.
Box 2: Commit the current version.
In Master Data Services, commit a version of a model to prevent changes to the model's members and their attributes. Committed versions cannot be unlocked.
Prerequisites:
Box 3: Create a copy of the current version.
In Master Data Services, copy a version of the model to create a new version of it. Note:

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.
