Question No: 11

In Framework Manager, role-playing dimension query subjects are used to resolve which reporting trap?

  1. Unwanted query splits (full outer joins).

  2. One query subject with several relationships.

  3. Multiple ambiguous joins betweentwo query subjects.

  4. Queries that reference two facts with no conformed dimension.

Answer: C

Question No: 12

In Framework Manager, it is recommended to model operational metadata as a virtual star schema for which one of the following reasons?

  1. Creates an easy-to-read data dictionary for end users.

  2. Ensures inner joins between data source query subjects.

  3. Helps to remove ambiguity and provide predictable results.

Answer: D Explanation:

If authors want to perform OLAP-style queries directly against a relational database, which Framework Manager modeling technique will a modeler use?

  1. Create regular and measure dimensions and set scope.

  2. Create shortcuts to regular dimensions and fact query subjects.

  3. Create star schema groupings for dimension and fact query subjects.

  4. Create relationships between regular dimensions and measure dimensions. Answer: A

Question No: 13

What technique can Framework Manager modelers useto implement a time dimension for models that lack a time dimension?

  1. Create relationships from date fields in one dimension to date fields in another dimension.

  2. Use parameter maps to map date values in one query subject to date values in anotherquery subject.

  3. Use the Time Dimension wizard to generate a time dimension and create the appropriate relationships.

  4. Identify a time dimension table source, import into the model and create relationships to fact query subjects.

Answer: D Explanation:

Users want to compare Actual Revenue and Sales Target values by Month. Actual Revenue values are stored at the day grain in the Orders Fact table. Sales Target values

are stored at the month grain in the Sales Target Fact table.

In Framework Manager, which technique will best prevent Sales Target values from being double-counted in Query Studio reports?

  1. Define both Month and Day determinant levels in the Time Dimension and Group By Day.

  2. Define both Month and Day determinant levels inthe Time Dimension and Group By Month.

  3. Create separate star schema groupings for Orders Fact and Sales Target Fact, both at the month grain.

  4. Set scope for Actual Revenue at the Day level and Sales Target at the Month level in the Dimension Map.

Answer: B

Question No: 14

To ensure a query subject is recognized as a fact by the Cognos 10 query engine in all query scenarios, the query subject requires which cardinality rule?

  1. One instance of attached cardinality must be 1..1.

  2. One instance of attached cardinality must be 1..n.

  3. All instances of attached cardinality must be either 1..n or 0..n.

  4. All instances of attached cardinality must be either 1..1 or 0..n.

Answer: C

Question No: 15

In Framework Manager, when using star schemagroupings in the business view, conformed dimensions can be identified by which one of the following?

  1. Using a different query subject icon for display in the studios.

  2. Viewing the properties of the query subjects in Report Studio.

  3. Viewing theproperties of the query subjects in Framework Manager.

  4. Using the same name for the dimension in each star schema grouping.

Answer: D

Question No: 16

Answer: A

Question No: 17

Although modelers can use model query subjects to create entire business views, it is recommended to use them to do which of the following?

  1. Resolve conflicting keys and indexes and generate minimized SQL.

  2. Combine facts and dimensions for intuitive ad hoc business views.

  3. Resolve reporting traps and simplify snowflake tables through consolidation.

  4. Provide dimensional information through the use of determinants.

Answer: C

Question No: 18

In Framework Manager, what are the minimum requirements to implement a stored procedure that expects arguments and make it available toauthors?

  1. Import the stored procedure, add it as a model calculation, and then publish it as part of a package.

  2. Import the stored procedure, provide values that satisfy the procedure#39;s arguments, retrieve a projection list and then publish it aspart of a package.

  3. Import the stored procedure, use it to create a calculation in the expression editor and then publish the calculation as part of a package.

  4. Import the stored procedure, set the type to Data Modification, provide values that satisfythe procedure#39;s arguments, retrieve a projection list and then publish it as part of a package.

Answer: B

Question No: 19

In Framework Manager, why is it recommended that modelers alter the default all-inclusive select statements of data source querysubjects as little as possible?

  1. To generate the most efficient SQL at run time and simplify model maintenance.

  2. To prevent the exclusion of columns from a table that may be required in future reports.

  3. To prevent improperly constructed SQL andreduce issues with model documentation and readability.

  4. To provide authors with access to all columns in a database table which reduces requests to the modeler?

Answer: A

Question No: 20

In order to create complex joins in Framework Manager, a modeler can use which of the following techniques?

  1. Open the Relationship Definition dialog, and then edit the join expression as required.

  2. Select the relationship, and then from the Actions menu, select quot;Merge in New Query Subjectquot;.

  3. Open theRelationship Expression dialog, and then change both cardinality settings to 0..n or 0..1.

  4. Right-click a relationship in the Object diagram or Context Explorer, and then select quot;Create Compound Joinquot;.
