Oracle Business Intelligence Foundation Suite 11g Essentials Sample Questions (Q85-Q90):

NEW QUESTION # 85
What are the two disadvantages of implementing Query Caching?

A. Increased network traffic
B. Storage space for cache
C. Needs a lot of administrators' time
D. Cache results being old
E. Reduction in BI server processing time

Answer: B,D

Explanation:
B: The problem with caching of any kind is how to deal with stale data. How you decide to deal with this depends on how time critical your business intelligence queries happen to be. OBIEE provides a wide variety of mechanisms for dealing with stale data. The cache can be purged automatically at intervals. Caching can be enabled selectively for individual physical tables, so that data in a frequently updated table is never cached.
OBIEE provides a set of ODBC procedures that can be called when ETL processes complete to programmatically purge designated tables. But, by far the best way to selectively purge the cache is to use an event polling table. This table is populated by the client database whenever changes are made to any table (by an ETL process for a data warehouse or by a table-based trigger for an OLTP database). At specified intervals the BI Server polls this event polling table and deletes from its cache any query results that are dependent on the changed data.

NEW QUESTION # 86
Which task can be performed after the Administrator link has been reached through logging into OBIEE?

A. Start or Stop BI Managed Servers
B. SSO enablement
C. Manage access to Subject Areas
D. Associate map layers to columns

Answer: D

Explanation:
It is asking for Which task (NOT Which Tasks).
Using Administration (not Administrator) link in OBIEE you can go to 'Manage Map Data' and manage map components.

NEW QUESTION # 88
What is an example of a Session Variable?

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

Answer: C

Explanation:
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.

NEW QUESTION # 89
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 one logical table sources and checking the "This Source should be combined with other sources at this level" box
B. By creating two Logical Fact Tables for each database
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 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.
E. By creating joins in the physical model so it looks like a single table

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).
