Oracle Business Intelligence Foundation Suite 11g Essentials Sample Questions (Q101-Q106):

NEW QUESTION # 101
What is an example of a Session Variable?

A. OLAP DSN
B. User Organization
C. ETL Load Date
D. Top Customers by Revenue

Answer: B

Explanation:
Explanation/Reference:
Note 1: There are four types of variables that you can use:
Session
Repository
Presentation
Request
Note 2: Session Variables
A session variable is a variable that is initialized at login time for each user. When a user begins a session, the Oracle BI Server creates a new instance of a session variable and initializes it.
There are as many instances of a session variable as there are active sessions on the Oracle BI Server. Each instance of a session variable could be initialized to a different value.
There are two types of session variables:
System - A session variable that the Oracle BI Server and Oracle BI Presentation Services use for specific purposes.
System session variables have reserved names that cannot be used for other kinds of variables (such as static or dynamic repository variables and non-system session variables).
Non-system - A system variable that the administrator creates and names. For example, the administrator might create a SalesRegion non-system variable that initializes the name of a user's sales region.
The administrator creates non-system session variables using the Oracle BI Administration Tool.
Incorrect answers:
A: ETL Load Date is a DAC Source System Parameter.
C: OLAP DSN is a Repository variable.

NEW QUESTION # 102
An organization has re-implemented one of its systems but has not moved history. One database has data for all years up to 2010 and the other has data for years from 2011 to the present. The organization needs data from the years 2010 and 2011 on a single report. How can you model this in the RPD?

A. By creating two Logical Fact Tables for each database
B. By creating two logical table sources and checking the "This Source should be combined with other sources at this level" box leaving the Fragmentation content area blank.
C. By creating two logical table sources, that specify in Content tab using the Fragmentation content areas to specify the years for each source
D. By creating joins in the physical model so it looks like a single table
E. By creating one logical table sources and checking the "This Source should be combined with other sources at this level" box

Answer: C

Explanation:
Explanation
Note: This source should be combined with other sources at this level (check box) Description: Check this box when data sources at the same level of aggregation do not contain overlapping information. In this situation, all sources must be combined to get a complete picture of information at this level of aggregation.
Note 2: To use a source correctly, the Analytics Server has to know what each source contains in terms of the business model. Therefore, you need to define aggregation content for each logical table source of a fact table.
The aggregation content rule defines at what level of granularity the data is stored in this fact table.
Use the Content tab of the Logical Table Source dialog box to define any aggregate table content definitions, fragmented table definitions for the source, and Where clauses (if you want to limit the number of rows returned).

NEW QUESTION # 103

A. Technical Requirements Definition
B. DashboardTesting
C. Data Quality Assessment
D. Business RequirementsDefinition

NEW QUESTION # 104
Identify the two true statements about alias tables.

A. Alias tables are set up to include best practice naming conventions for physical table names.
B. Alias tables are set up to create another physical copy of the data.
C. Alias tables are set up to avoid triangular or circular joins.
D. Alias tables are set up to create a copy of the data with a filter applied to it.

Answer: A,C

Explanation:
It is a best practice to create aliases for all tables. Aliases are created in the Physical Layer of the repository. Some of the benefits of using aliases are given below:
(A) * An alias is used to avoid circular joins and to configure self joins.
*You can create a join relationship which is different than the actual foreign key relationship in the database. This helps in defining relationships to meet business model criteria.
*Aliases can function in numerous ways to define business model e.g. a table can act both as a dimension and a fact using aliases.
(B) * You can rename aliases to make physical and business model easier to understand.

NEW QUESTION # 105
What is the process in which there is redundancy of data to improve performance?

A. Normalization
B. Granularity
C. Cardinality
D. Denormalization
E. Redundancy

Answer: D

Explanation:
Denormalization is the process of intentionally backing away from normalization to improve performance by suppressing join and permitting the use of star transformation technique.
Denormalization should not be the first choice for improving performance and should only be used for fine tuning of a database for a particular application.
