Oracle Business Intelligence Foundation Suite 11g Essentials Sample Questions (Q62-Q67):

NEW QUESTION # 62
A customer has a requirement for rolling period calculations. What two additional steps will need to be done to enable this in the repository?

A. Specifying a sort order in the Logical Table dialog
B. Designating a chronological key for every level of every dimension hierarchy
C. Clicking the "Time" option in the Logical Table Source Dialog
D. Designating a chronological key for every logical column in the Logical Table Source
E. Clicking the "Time" option in the Logical Dimension Dialog

Answer: B,E

Explanation:
Creating Logical Time Dimensions
Compared to modeling an ordinary dimension, the time dimension requires just two additional steps: selecting the Time option in the Logical Dimension dialog, and designating a chronological key for every level of every dimension hierarchy.
Note: Time dimensions and chronological keys. You can identify a dimension as a time dimension. At least one level of a time dimension must have a chronological key. The following is a list of some guidelines you should use when setting up and using time dimensions:
* At least one level of a time dimension must have a chronological key.
* All time series measures using the AGO, TODATE, and PERIODROLLING functions must be on time levels. AGO, TODATE, and PERIODROLLING aggregates are created as derived logical columns.

NEW QUESTION # 63
What are the two leading design solutions recommended by Oracle that you would use for performance?

A. Avoid using GuidedNavigation unless the data set is large
B. Avoid returning big data sets within the Dashboard
C. Design requests that use Complex Queries
D. Use Cache

Answer: B,D

Explanation:
C: OBIEE Caching and Cache Seeding
Cache is a component that improves performance by transparently storing data such that future requests for the same criteria can be served much faster. Like other application cache is not virtual memory in OBIEE. In OBIEE cache will be stored as files on the Hard Disk of the OBIEE Server in the form of files. By Default caching is enabled in the OBIEE server configuration.
For time-consuming Dashboard Pages, we can use the concept of cache seeding in OBIEE, this can be configured as a scheduled job that will ensure that the data is cached and readily available as and when the user runs the dashboard.

NEW QUESTION # 64
A customer always wants Aggregate Table l to be looked at first to see if it can answer the query. What should be done to make sure this happens?

A. Set the Priority Croup to 5.
B. Set the Priority Group to 0.
C. Make Aggregate Table 1 the first table in the list of Logical Table Sources.
D. Do not map the logical level in the Content tab.

Answer: B

Explanation:
Explanation
Priority group
You can set priority group numbers to determine which logical table source should be used for queries for which there is more than one logical table source that can satisfy the requested set of columns.
For example, you might have user queries that can be fulfilled by both a data warehouse and an OLTP source.
Often, access to an operational system is "expensive," while access to a data warehouse is "cheap." In this situation, you can assign a higher priority to the data warehouse to ensure that all queries are fulfilled by the data warehouse if possible.
Note that the priority group of a given logical table source does not always ensure that a particular query will be fulfilled by that source.
Priority Group Designation
0 the highest-priority source (the default)
1 a lowest-priority source

NEW QUESTION # 65
Which option is not an example of a level-based measure?

A. Regional Revenue
B. Brand Cost
C. Sales
D. Employee Salary

Answer: B

Explanation:
Explanation
Note 1: A level-based measure is a column whose values are always calculated to a specific level of aggregation.
The calculation of this measure is independent of the query grain and used always the aggregation grain of the logical column.
Level-based measures allow :
* to return data at multiple levels of aggregation (the query grain and the level-based column grain) with one single query
* to create share measures (percentage), that are calculated by taking some measure and dividing it by a level-based measure. For example, you can divide salesperson revenue by regional revenue to calculate the share of the regional revenue each salesperson generates.
Note 2: To create a level based measure as the amount sold by region, you can:
* make a copy of the Amount Sold logical column
* and then
/ drag the logical column into its hierarchy level
/ or set the aggregation grain in the level tab of the logical column property.

NEW QUESTION # 66
The ODBC DSN is never used for _______.

A. Changing passwords
B. Initial import of the physical layer metadata on a Windows server
C. Initial import of the physical layer metadata, query execution, and data access on a Windows Server
D. Comparing RPDs
E. Query execution and data access on a Windows server

Answer: D

Explanation:
You do not use ODBC DSN to compare repositories.
Note: When an ODBC based application connects to a database, it connects to a logical name, the Data Source Name (DSN), which identifies the datasource to which it wants to connect.
Some external repository of configuration information holds the various DSN values that are available, together with the necessary configuration and control information needed by the ODBC driver to establish a connection and manage usage of the data source.
The DSN (data source name) is a data structure that contains the information about a specific data source (database, ...), typically used by an ODBC driver to be able to connect to it.
The DSN contains information about the data source such as:
the name,
the directory,
and the driver.
On Windows, the DSN also specifies the ODBC driver to be used to access the database.
