You need to create a new dimension that allows users to list shipments by the country where the product is shipped.

Which relationship type should you use between the Shipment table and the new dimension?

A.

no relationship

B.

regular

C.

fact

D.

referenced

E.

many-to-many

F.

data mining

Answer: E

Explanation/Reference:

Explanation:

Many to Many Dimension Relationships.

In most dimensions, each fact joins to one and only one dimension member, and a single

dimension member can be associated with multiple facts. In relational database terminology, this is referred to as a one-to-many relationship. However, it is frequently useful to join a single fact to multiple dimension members. For example, a bank customer might have multiple accounts (checking, saving, credit card, and investment accounts), and an account can also have joint or multiple owners. The Customer dimension constructed from such relationships would then have multiple members that relate to a single account transaction.

Question No.13

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 InMemory with DirectQuery.

Does the solution meet the goal?

A.

Yes

B.

No

Answer: B

Explanation/Reference:

Explanation:

With InMemory with DirectQuery: Queries use the cache by default, unless otherwise specified in the connection string from the client.

Question No.14

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 Microsoft SQL Server Analysis Services (SSAS) instance that is configured to use multidimensional mode. You create the following cube:

image

Users need to be able to analyze sales by product and color. You need to create the dimension.

Which relationship type should you use between the InternetSales table and the new dimension?

A.

no relationship

B.

regular

C.

fact

D.

referenced

E.

many-to-many

F.

data mining

Answer: D

Explanation/Reference:

Explanation:

A reference dimension relationship between a cube dimension and a measure group exists when the key column for the dimension is joined indirectly to the fact table through a key in another dimension table, as shown in the following illustration.

image

A reference dimension relationship represents the relationship between dimension tables and a fact table in a snowflake schema design. When dimension tables are connected in a snowflake schema, you can define a single dimension using columns from multiple tables, or you can define separate dimensions based on the separate dimension tables and then define a link between them using the reference dimension relationship setting. The following figure shows one fact table named InternetSales, and two dimension tables called Customer and Geography, in a snowflake schema.

image

You can create two dimensions related to the InternetSales measure group: a dimension based on the Customer table, and a dimension based on the Geography table. You can then relate the Geography dimension to the InternetSales measure group using a reference dimension relationship using the Customer dimension.

Question No.16

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?

A.

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

B.

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

C.

In the SQL Server database, implement a SYNONYM.

D.

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

Answer: D

Question No.17

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 an existing multidimensional cube that provides sales analysis. The users can slice by date, product, location, customer, and employee.

The management team plans to evaluate sales employee performance relative to sales targets. You identify the following metrics for employees:

Answer: A

Question No.18

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 deploy a tabular data model to an instance of Microsoft SQL Server Analysis Services (SSAS). The model uses an in-memory cache to store and query data. The data set is already the same size as the available RAM on the server. Data volumes are likely to continue to increase rapidly.

Your data model contains multiple calculated tables.

The data model must begin processing each day at 2:00 and processing should be complete by 4:00 the same day. You observe that the data processing operation often does not complete before 7:00. This is adversely affecting team members.

You need to improve the performance. Solution: Enable Buffer Cache Extensions. Does the solution meet the goal?

A.

Yes

B.

No

Answer: B

Explanation/Reference:

Explanation:

In this scenario we would need both Buffer Cache Extensions and SSD. The buffer pool extension provides the seamless integration of a nonvolatile random access memory (that is, solid-state drive) extension to the Database Engine buffer pool to significantly improve I/O throughput.

Does the solution meet the goal?

A.

Yes

B.

No

Answer: B

Question No.20

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?

A.

Set the AttributeHierarchyVisible property to False.

B.

Set the AttributeHierarchyEnabledproperty to False.

C.

Set the AttributeVisibility property to Hidden.

D.

Set the Usage property to Regular.

E.

Set the AttributeHierarchyDisplayFolder property to Hidden.

Answer: A

Explanation/Reference:

Explanation:

The value of the AttributeHierarchyEnabled property determines whether an attribute hierarchy is created. If this property is set to False, 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 the AttributeHierarchyEnabled property is set to True, the value of the AttributeHierarchyVisible property determines whether the attribute hierarchy is visible independent of its use in a user-defined hierarchy.
