Question 1

You are developing a SQL Server Analysis Services (SSAS) tabular project.

You need to grant the minimum permissions necessary to enable users to query data in a data model.

Which role permission should you use?

AExplorer

BProcess

CBrowser

DAdministrator

ESelect

FRead

Answer : F

Question 2

You are responsible for installing new database server instances.

You must install Microsoft SQL Server Analysis Services (SSAS) to support deployment of the following projects. You develop both projects by using SQL Server Data Tools.

You need to install the appropriate services to support both projects.

Which two actions should you perform? Each correct answer presents part of the solution.

AInstall one tabular instance of SSAS and enable the Data Mining Extensions.

BInstall one multidimensional instance of SSAS.

CInstall one tabular instance of SSAS.

DInstall a multidimensional instance and a Power Pivot instance of SSAS on the same server.

EInstall two separate tabular instances of SSAS.

Answer : B, C

Analysis Services can be installed in one of three server modes: Multidimensional and Data Mining (default), Power Pivot for SharePoint, and Tabular.

Question 3

You are optimizing a Microsoft SQL Server Analysis Services (SSAS) multidimensional model over a SQL Server database. You have a table named City which has several dimensions that do not contain a space in their names. One dimension is named SalesTerritory rather than Sales Territory.

You need to ensure that Report developers can drag the attribute name to the report rather than having to re-label the attributes by implementing spaces. You must minimize administrative effort and not break any upstream processes.

What should you do?

AIn the SQL Server database, run the system procedure sp_rename to rename the columns in the base tables with the target name.

BIn SQL Server Management Studio, navigate to the City table, expand the columns, press F2, and rename the columns in the base tables.

CIn the SQL Server database, implement a SYNONYM.

DIn the SQL Server database, implement a view over the City table that aliases the columns in the tables.

Answer : D

Question 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 administer a Microsoft SQL Server Analysis Services (SSAS) tabular model for a travel agency that specializes in vacation packages. Vacation bookings and packages are stored in a SQL Server database. You use the model as the basis for customer emails that highlight vacation packages that are currently underbooked, or projected to be underbooked.

The company plans to incorporate cruise ship vacation packages. Cruise ship vacation packages include new features such as region availability and cruise line specialties that require changes to the tabular model.

You must ensure that the tabular model reflects the new vacation packages.

You need to configure the tabular data model.

What should you do?

AEnsure that DirectQuery is enabled for the model.

BEnsure that DirectQuery is disabled for the model.

CEnsure that the Transactional Deployment property is set to True.

DEnsure that the Transactional Deployment property is set to False.

EProcess the model in Process Full mode.

FProcess the model in Process Data mode.

GProcess the model in Process Defrag mode.

Answer : E

Process Full processes an Analysis Services object and all the objects that it contains. When Process Full is executed against an object that has already been processed, Analysis Services drops all data in the object, and then processes the object. This kind of processing is required when a structural change has been made to an object, for example, when an attribute hierarchy is added, deleted, or renamed.

Question 5

You are building a Microsoft SQL Server Analysis Services multidimensional model over a SQL Server database. In a cube named OrderAnalysis, there is a standard cube dimension named Stock Item.

This dimension has the following attributes:

Users report that the attributes Stock Item Key and Photo are distracting and are not providing any value. They have asked for the attributes to be removed. However, these attributes are needed by other cubes.

You need to hide the specified attributes from the end users of the OrderAnalysis cube. You do not want to change the structure of the dimension.

Which change should you make to the properties for the Stock Item Key and Photo attributes?

ASet the AttributeHierarchyVisible property to False.

BSet the AttributeHierarchyEnabledproperty to False.

CSet the AttributeVisibility property to Hidden.

DSet the Usage property to Regular.

ESet the AttributeHierarchyDisplayFolder property to Hidden.

Answer : A

The value of theAttributeHierarchyEnabledproperty determines whether an attribute hierarchy is created. If this property is set toFalse, the attribute hierarchy is not created and the attribute cannot be used as a level in a user hierarchy; the attribute hierarchy exists as a member property only. However, a disabled attribute hierarchy can still be used to order the members of another attribute. If the value of theAttributeHierarchyEnabledproperty is set toTrue, the value of theAttributeHierarchyVisibleproperty determines whether the attribute hierarchy is visible independent of its use in a user-defined hierarchy.

Question 6

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.)

ACreate a new role named Sales Persons with Read permission. Add each salesperson's logon as a member to the role.

BAdd 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.

CCreate 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.

DCreate 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.

Answer : B

Question 7

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.

A company has an e-commerce website. When a customer places an order, information about the transaction is inserted into tables in a Microsoft SQL Server relational database named OLTP1. The company has a SQL Server Analysis Services (SSAS) instance that is configured to use Tabular mode. SSAS uses data from OLTP1 to populate a data model.

Sales analysts build reports based on the SSAS model. Reports must be able to access data as soon as it is available in the relational database.

You need to configure and deploy an Analysis Services project to the Analysis Services instance that allows near real-time data source access.

Solution: In the Deployment Option property for the report, you set the Query Mode to DirectQuery with InMemory.

Does the solution meet the goal?

AYes

BNo

Answer : A

With DirectQuerywithInMemory mode the queries use the relational data source by default, unless otherwise specified in the connection string from the client.
