Microsoft Developing SQL Data Models - 70-768 FREE EXAM DUMPS QUESTIONS & ANSWERS]

Question 1

Drag and Drop Question
You install a SQL Server Analysis Services (SSAS) instance in tabular mode on a server.
While processing a very large tabular model, you receive an out-of-memory error. You identify that the amount of physical memory in the server is insufficient. Additional physical memory cannot be installed in the server.
You need to configure the server to allow paging to disk by using the operating system page file (pagefile.sys).
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.)

Correct Answer:

Explanation:
* View or set configuration properties in Management Studio In SQL Server Management Studio, connect to an Analysis Services instance. In Object Explorer, right-click the Analysis Services instance, and then clickProperties. The General page appears, displaying the more commonly used properties. To view additional properties, click theShow Advanced (All) Propertiescheckbox at the bottom of the page.
Modifying server properties is supported only for tabular mode and multidimensional mode servers. If you installed PowerPivot for SharePoint, always use the default values unless you are directed otherwise by a Microsoft product support engineer.
* VertiPaqPagingPolicy
Specifies the paging behavior in the event the server runs low on memory. Valid values are as follows:
Zero (0) is the default. No paging is allowed. If memory is insufficient, processing fails with an out- of-memory error.
1 enables paging to disk using the operating system page file (pagefile.sys). When VertiPaqPagingPolicy is set to 1, processing is less likely to fail due to memory constraints because the server will try to page to disk using the method that you specified. Setting the VertiPaqPagingPolicy property does not guarantee that memory errors will never happen. Out of memory errors can still occur under the following conditions:
There is not enough memory for all dictionaries. During processing, Analysis Services locks the dictionaries for each column in memory, and all of these together cannot be more than the value specified for VertiPaqMemoryLimit.
There is insufficient virtual address space to accommodate the process. To resolve persistent out of memory errors, you can either try to redesign the model to reduce the amount of data that needs processing, or you can add more physical memory to the computer.
Applies to tabular server mode only
* Incorrect: VertiPaqMemoryLimit
If paging to disk is allowed, this property specifies the level of memory consumption (as a percentage of total memory) at which paging starts. The default is 60. If memory consumption is less than 60 percent, the server will not page to disk. This property depends on the VertiPaqPagingPolicyProperty, which must be set to 1 in order for paging to occur.
Applies to tabular server mode only.

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. Determine whether the solution meets the stated goals.
You have a Microsoft SQL Server Analysis Services (SSAS) multidimensional database that stores customer and order data for customers in the United States only. The database contains the following objects:

You must create a KPI named Large Sales Target that uses the Traffic Light indicator to display status. The KPI must contain:

You need to create the KPI.
Solution: You set the value of the Status expression to:

Does the solution meet the goal?

A. No B. Yes

Question 3

What type of partitioning strategy should you implement to support the analysis of hourly Internet sales transactions?

A. Set the model to DirectQuery With In-Memory Mode. Define a sample partition for the Internet Sales table to view data during development. B. Create one partition per day dynamically by running an SSIS package daily to build the new partition. Load the data for the current day by performing a Process Full operation on the partition. C. Create one partition per hour per day dynamically by running an SSIS package each hour to build the new partition. Load the data for the current hour by performing a Process Add, and then execute a Process Recalc on the partition D. Convert the model to DirectQuery. Add columnstore indexes to the source tables. In the model, define a sample partition for all tables to view data during development.

Question 4

You are troubleshooting query performance for a SQL Server Analysis Services (SSAS) cube.
A user reports that a Multidimensional Expressions (MDX) query is very slow.
You need to identify the MDX query statement in a trace by using SQL Server Profiler.
Which event class should you use?

A. Progress Report Begin B. Query Begin C. Get Data From Aggregation D. Execute MDX Script Begin E. Query Subcube F. Calculate Non Empty Begin

Question 5

You are developing a SQL Server Analysis Services (SSAS) tabular project.
In the data warehouse, a table named Sales Persons and Territories defines a relationship between a salesperson's name, logon ID, and assigned sales territory.
You need to ensure that each salesperson has access to data from only the sales territory assigned to that salesperson. You need to use the least amount of development effort to achieve this goal.
What should you do? (More than one answer choice may achieve the goal. Select the BEST answer.)

A. Create a separate tabular model for each sales territory and assign each tabular model a corresponding sales territory name.
Grant each salesperson access to the corresponding tabular model of the assigned sales territory. B. Create a new Active Directory Domain Services (AD DS) security group and add each salesperson as a member.
Then create a new role named Sales Persons with Read permission.
Add the group as a member to the new role. C. Add the Sales Persons and Territories table to the model, define the relationships, and then implement dynamic security by using row filters.
Grant each salesperson access to the model. D. Create a new role named Sales Persons with Read permission.
Add each salesperson's logon as a member to the role.

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 administer a Microsoft SQL Server Analysis Services (SSAS) tabular model for a retail company.
The model is the basis for reports on inventory levels, popular products, and regional store performance.
The company recently split up into multiple companies based on product lines.
Each company starts with a copy of the database and tabular model that contains data for a specific product line.
You need to optimize performance of queries that use the copied tabular models while minimizing downtime.
What should you do?

A. Process the model in Process Full mode. B. Ensure that DirectQuery is disabled for the model. C. Ensure that the Transactional Deployment property is set to False. D. Ensure that DirectQuery is enabled for the model. E. Ensure that the Transactional Deployment property is set to True. F. Process the model in Process Data mode. G. Process the model in Process Defrag mode.
