NEW QUESTION # 42
A customer needs to do a cross database join between two tables where, one of the tables has a small number of values and the other has a large number of values. How can you optimize the way the BI Server processes the query?
- A. By specifying a many to one join between the tables with the small and large numbers of values
- B. By specifying a one-to-many join between the tables with the small and large numbers of values
- C. By creating your joins by using the Business Model Diagram
- D. By specifying a driving table
- E. By creating your logical join by using the Joins Manager
Answer: D
Explanation:
Explanation/Reference:
You can specify a Driving table parameter in a complex join.
Driving tables are for use in optimizing the manner in which the Oracle BI Server processes cross- database joins when one table is very small and the other table is very large.
The BI Server will query the driving table (the small one) and will get a list of values. The BI Server will then generate a second SQL using a parameterized IN list with the values from the first query.
Specifying driving tables leads to query optimization only when the number of rows being selected from the driving table is much smaller than the number of rows in the table to which it is being joined.
NEW QUESTION # 43
What are the two types of Session Variables?
- A. System
- B. Static
- C. Non System
- D. Dynamic
Answer: A,C
Explanation:
Explanation/Reference:
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.
Note: 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.
NEW QUESTION # 44
Identity the three advantages of the BI Server metadata repository.
- A. Three layers support the highest level of security
- B. Ability to change physical sources without losing reports
- C. Mapping of federated data sources to one logical object
- D. Little changes in the physical layer to shift from development to production environment
Answer: A,C,D
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:
NEW QUESTION # 45
One of the most common uses of Dynamic Repository Variables is to setup filters for use in reporting.
Which variable below is a valid example of a Dynamic Repository Variable?
- A. CurrentMonth
- B. Year
- C. Month
- D. Quarter
Answer: A
Explanation:
Explanation/Reference:
CurrentMonth can be calculated by a sql statement.
Note:
REPOSITORY VARIABLE(DYNAMIC)
Initialized when BI server is started
Assigned value dynamically based on the result of a query
Value is dependent of the sql provided in Initialization Block
Create a dynamic variable and provide a Name and Default Initializer.Create a new initialization block by clicking on the New button in the above screen.
Provide Intialization Block variable Name
Click on "Edit Data Source" button and provide the sql to be used for the variable, e.g.
select lower(sys_context('USERENV','SESSION_USER'))||
'@'||
lower(sys_context('USERENV','DB_NAME'))
from dual;
NEW QUESTION # 46
Which option is not an example of a level-based measure?
- A. Employee Salary
- B. Sales
- C. Brand Cost
- D. Regional Revenue
Answer: C
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 # 48
Which option describes how OBIEE natively integrates with HFM?
- A. OBIEE does not support HFM integration
- B. Through Essbase connectivity
- C. Direct relational database access
- D. Through EPM Analytic Data Model (ADM) connectivity
Answer: D
Explanation:
BI EE uses the ADM driver to extract the data from HFM.
Note: HFM (Hyperion Financial Management)
Example:
I EE connects to HFM through JavaHost. So, the setup for configuring the connectivity is to
basically make the EPM environment variables available for access to BI EE. Before making the
changes, there are a couple of things to be aware of
1.Ensure that DCOM is enabled on the BI Server machine. This is needed for HFM client to work/connect properly with HFM Server.
2.Ensure that HFM Client is installed.
The above assumes EPM 11.1.2.x version. If you are on Hyperion 9.3.3, then you need to have the ADM drivers installed manually. All of this is documented clearly. So, rather than re-iterating that i will just point to the link here. Ensure that you follow all the steps mentioned in the docs else you will have issues in the connectivity. Once all the pre-requisite steps are done, we start off with the metadata import process.

NEW QUESTION # 49
Select the correct statement.
- A. Cache needs to be purged to refresh data.
- B. Cache can degrade query performance by reading data from the disk instead of the database.
- C. Cache is seeded by manually running PL/SQL at the back end database.
- D. Cache can increase traffic to back end database.
- E. Cache provides fast and always up-to-date information.
Answer: A
Explanation:
Explanation/Reference:
In a standard OBIEE implementation, we generally want to purge and re-build the cache after every ETL (extract, transform, and load) run.
Incorrect answers:
A: A cache item might be out of date.
B: Cache reduces traffic to the back end database. At worst it does not change the amount traffic.
D: The cache disk should be at faster than the disk of the database.
E: 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 # 50
The Time Dimension hierarchy is a good example of a__________.
- A. Level-basedTime Dimension hierarchy
- B. Ragged Hierarchy
- C. Skip Level Hierarchy
- D. Value-based Hierarchy
Answer: A
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 # 52
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 Group to 0.
- B. Make Aggregate Table 1 the first table in the list of Logical Table Sources.
- C. Do not map the logical level in the Content tab.
- D. Set the Priority Croup to 5.
Answer: A
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 # 54
A customer needs to have a calculation done prior to aggregating the data. How would you accomplish this?
- A. By creating a derived measure in the Column Mapping dialog box by using the physical table columns.
- B. By creating a derived measure by using the Logical Columns available
- C. By creating a derived measure by using Logic Columns available and changing the aggregation type
- D. By creating a derived metric by using the Expression Builder
- E. By creating a derived metric by using the Calculation Wizard
Answer: A
Explanation:
Note 1: OBIEE offers two calculation types for measure in the repository:
logical
physical
You can define calculations in either of the following ways:
* Before the aggregation, in the logical table source.
* After the aggregation, in a logical column derived from two other logical columns. For example: sum(col A)
* sum(col B)
Note 2: A measure column is a column unlike the baseline column that has a default aggregation rule defined in the Aggregation tab of the Logical Column dialog in the repository.
Measure columns always calculate the aggregation with which they are defined.
Measures need to be defined in a logical fact. Any column with an aggregation rule is a measure.
NEW QUESTION # 55
When adding a new dimension to an existing logical table, what is the significance of the Logical Level setting in the Logical Table Source properties?
- A. It determines the actual value of the dimension.
- B. It defines the granularity of the dimension.
- C. It creates a new session variable.
- D. It creates a foreign key relationship.
Answer: B
Explanation:
OBIEE - Grain (Level of summarization)
Grain definition in the context of OBIEE.
The following list describes the different grains in navigating a query:
*Aggregation grain. The grain of the aggregate source of from a level based metrics
*Query grain. The grain of the request.
*Time Series grain. The grain at which the time series function aggregation is requested.
*Storage grain. The query in the example can be computed from daily sales or from monthly sales, or from quarterly sales.
Note:
The aggregation grain is defined in the content tab of the logical table source.
When the query grain match the aggregation grain of a logical table source, this one is used to
create the physical query.
