Oracle Business Intelligence Foundation Suite 11g Essentials Sample Questions (Q38-Q43):

NEW QUESTION # 38
The Time Dimension hierarchy is a good example of a__________.

  • A. Skip Level Hierarchy
  • B. Ragged Hierarchy
  • C. Value-based Hierarchy
  • D. Level-based Time Dimension hierarchy

Answer: D

Explanation:
Explanation
Level-based Hierarchy
Level-based hierarchy is the first type of hierarchy in OBIEE.
Consists of an ordered set of two or more levels. For example, a Time hierarchy might have three levels for Year, Quarter, and Month. Level-based hierarchies can also contain parent-child relationships.
Dimension hierarchy levels allow :
* to perform aggregate navigation,
* to configure level-based measure calculations,
* users from Dashboard and Answers to drill down from one parent to a child level.
Special type of level-based dimension are supported:
* Unbalanced (or ragged) and Skip-level hierarchy
* time dimension to provides special functionality for modeling time series data.


NEW QUESTION # 39
The Consistency Checker checks______.

  • A. Mappings to the physical objects
  • B. Syntax errors in derived logical columns
  • C. For objects deleted from the database
  • D. The validity of objects outside the metadata using the connection

Answer: A

Explanation:
Explanation/Reference:
Consistency check is one of the process to check whether a repository is yielding proper results in Answer reports. It checks whether;
* All logical columns are mapped correctly to physical columns (B).
* All logical dimension tables have a logical key.
* There are at least two logical tables in the business model; one is a logical fact table, the other is logical dimension table with join condition.
* There are no circular logical join relationships.
* A presentation catalog exists for the business model.


NEW QUESTION # 40
Identity the three advantages of the BI Server metadata repository.

  • A. Ability to change physical sources without losing reports
  • B. Three layers support the highest level of security
  • C. Little changes in the physical layer to shift from development to production environment
  • D. Mapping of federated data sources to one logical object

Answer: B,C,D

Explanation:
Explanation
A: OBIEE Federated Repository
Instead of moving data in to a single database, OBIEE - BI Administration can access multiple databases and create a single federated repository.OBIEE BI Answer uses this federated repository and build the ad-hoc reports and dashboards.
D: Repository Metadata Consists of 3 Layers
* The Physical Layer (Schema)
* The Business Model and Mapping Layer
* The Presentation Layer
Note:
star schema


NEW QUESTION # 41
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 table sources, that specify in Content tab using the Fragmentation content areas to specify the years for each source
  • B. By creating one logical table sources and checking the "This Source should be combined with other sources at this level" box
  • C. 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.
  • D. By creating joins in the physical model so it looks like a single table
  • E. By creating two Logical Fact Tables for each database

Answer: A

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).
Reference: Siebel Business Analytics Server Administration Guide > Creating and Administering the Business Model and Mapping Layer in a Repository > Creating and Administering Logical Table Sources (Mappings) > Defining Content of Logical Table Sources


NEW QUESTION # 42
Identify the correct mode to use when opening the web catalog while performing security settings modifications and migrations.

  • A. Managed
  • B. UnManaged
  • C. Offline
  • D. Online

Answer: D

Explanation:
In online mode, you connect to a catalog on a running web server. In this mode your permissions are applied, you can select a locale, and you can see the effects of any localization on the catalog. You can see only those objects for which you have the appropriate permissions. Both Presentation Services and the web server must be running for you to open catalogs in online mode.
Use online mode when you want to make minor incremental changes or additions to the catalog, such as changes to permissions, updates to a single object, or migration of new objects to a production environment.
Note:
* You can open a catalog in one of two modes - online or offline. Both modes can operate against an actual production catalog, with no need for any downtime.
* Repository changes can be done in either online
or offline mode. Online mode is when BI Server
is actively reading the repository file (when a
user is logged in). Offline is when BI Server is
idle. Best practice is to develop in Offline mode.
Minor changes can be made when in online
mode.
