2025 Realistic Verified Free Oracle 1Z1-591 Exam Questions

Q71. The customer is questioning the necessity to have a data warehouse in place. They want to run OBIEE against various transactional systems. Identify the two limitations.

Operational system might be overburdened with analytical requests resulting in had performance for transactional processes.

TheBIserver cannot integrate various sourcesin one metadata model.

Dataquality issues might emerge, due to missing data cleansing.

Business issues are depending on real-time data.

Q72. Use of the Enterprise Install option is recommended for which three options?

Multiple instances on a single computer

Scale out for High Availability and Failover

Support for high security requirements

Evaluation of end user functionality

Single users working on a single computer

Explanation
Enterprise Install: This installation type assumes some familiarity with Oracle Business Intelligence. All software components are downloaded onto one computer. You can accept the default configuration settings or use your own. You use this installation type when you have an established Oracle WebLogic domain, and you want to extend it to the Oracle Business Intelligence application. This install option is typically used for more advanced deployments with multiple users, such as to scale out a deployment on additional computers.

Q73. A customer needs to have a calculation done prior to aggregating the data. How would you accomplish this?

By creating a derived measure by using the Logical Columns available

By creating a derived measure in the Column Mapping dialog box byusing the physical tablecolumns.

By creating a derived measure by using LogicColumnsavailable andchanging theaggregationtype

By creating a derived metricby using the Expression Builder

By creatinga derived metricby using the Calculation Wizard

Note1: 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.

Q74. Derived metrics are_____.

Derived from other logical columns

Derived from other physical columns

Used to apply pre-aggregation calculations to measures

Used to rename measures to user-friendly names

Q75. OBIEE 11g authentication of users is performed by which two components listed below?

Repository file (rpd)

Embedded WebLogic LDAP server

External directories such as Active Directory using WebLogic and Fusion Middleware’s Oracle Platform Security Services framework

BI Presentation Services

Q76. Which two steps are needed to set up Failover support for an OBIEE deployment?

Use Installer to affect Horizontal scale out of an existing instance

Employ WebLogic Enterprise Edition, licensed separately

Use Installer to set up separate single instances, then apply Horizontal scale out clustering

Apply OBIEE Clustering option

Leverage spare hardware capacity of single machine by using Vertical scale out option

Explanation/Reference:
Horizonal Scaleout of System Components
* Used for adding additional managed servers (Java components) and
system components to an existing cluster
* Used for scalability and failover
* Set up via the Universal Installer > Scale Out BI System option

Q77. Which three components are part of a cluster server?

Master Server

Repository Publishing Directory

Primary Cluster Controller

Web Server

Server request Controller

Oracle BI Cluster Server Components
*Oracle Business Intelligence Cluster Controller: The Cluster Controller determines which BI Server works in the cluster. It monitors the operation of servers in the cluster. The Cluster Controller is deployed in active-passive mode.
*Clustered BI Servers: The BI Cluster Server feature supports up to 16 BI Servers in a network domain to act as a single server. BI Servers in the cluster share requests from multiple Oracle BI clients.
*Master BI Server: A clustered Oracle Business Intelligence Server is designated as the Master BI Server. The Oracle Business Intelligence Administration Tool connects to the master BI Server for online repository changes.
*Cluster Manager: The Cluster Manager is available in the Administration Tool when a repository is opened in online mode. The Cluster Manager enables Oracle BI Server clustered instances.

Q78. Cache in OBIEE is used to_____. Select the two correct answers.

improve performance of Dashboards and Analysis

decrease query response time

improve Analysis data quality

eliminate Write Back Capabilities

create Aggregate tables

Decrease query response time which will improve performance for Dashboards and Analysis.

Q79. Which resource identifies the OBIEE Web Catalog (webcat)?

instanceconfig.xml

RCU Schema

Identity Store

nqsconfig.ini

Admin Server

C: Oracle Business Intelligence authenticates users and get groups using an Oracle WebLogic Server authentication provider against user information held in an identity store.

Q80. Which of the following characteristics pertain to a “ragged” hierarchy?

It can only be stored in an XML structure.

A branch of the hierarchy may have a different number of levels than other branches.

All values can have a maximum of six levels.

It creates multiple levels of hierarchy in the databasetable.

Ragged Hierarchies are hierarchies where some routes down the hierarchy are longer than others; for example, you may have an organizational hierarchy for salespeople where the overall boss has two assistant managers, one of them works on their own and another has three sales managers under them; some of those sales manager may have sales staff under
them, and some sales staff may have trainees under them.

Q81. How do you get the BI plug-in for MS Office?

By contacting the administrator

By downloading it from the BI Server

By downloading it from the Database Server

By downloading it from Microsoft Server

Explanation/Reference:
Download and installation of the client
The client install executable is available for download from the More Products menu in Oracle BI Interactive Dashboards and Oracle BI Answers.
See picture below.

Q82. When designing a Star Schema, which option does not apply?

The facts are quantifiable.

The fact has several foreign keys that are primary keys in the dimensional table

Fact table is joined to the related dimensional tables.

Dimensional tables are normalized.

Dimensional tables have one attribute primary key as Product_ID for products.

Explanation
In a Star Schema the dimensional tables does not need to be normalized.
A Snowflake Schema is a modified Star Schema that has normalized the dimensional tables.

Q83. Point-and-click generation of case statement logic can be accessed via which option?

Column Formula -> Bins tab

Compound Layout

Column Properties -> Conditional Format tab

Advanced Tab

Subject Area metrics

Explanation/Reference:
The “Edit Column Formula” dialog box has a second,
very tiny tab called, “Bins.” You can use this tab to have OBIEE
build a CASE statement for you in a formula (you can also create
a CASE statement yourself by using one of the functions that
appears under “Expressions” if you want). A CASE statement is a
lot like an IF-THEN-ELSE statement, except that it’s a little easier
to read when you have multiple options. Basically, it puts values
in different buckets that you define.
Note:
Figure:

Incorrect answers:
C: The “Conditional Format” tab lets you set formatting when specific conditions are met.

Q84. 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?

Make Aggregate Table 1 the first table in the list of Logical Table Sources.

Do not map the logical level in the Content tab.

Set the Priority Group to 0.

Set the Priority Croup to 5.

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

Q85. What is the first step when creating an Aggregate table in the OBI repository?

Test the Aggregate table by using Analysis

Specify the Fact table that you want to aggregate

Use Job Manager to run the Aggregate script

Create a dedicated Connection Pool

Explanation
Steps for Creating Aggregate Tables in OBIEE
1. Create all Dimension Tables, Fact Tables & Hierarchies, which are required to be aggregated.
2. Go to ToolsaUtilities (from Administration tool menu bar), a dialog box will pop up with all available utilities.
3. Select Aggregate Persistence Wizard, and then click Execute Button.
4. Now Select appropriate path where you need to generate Aggregate Table SQL.
Note : Click Generate DDL file for first time generation of Aggregate Table Click Next, to move to next page (Select Business Model & Measure Page) In Select Business Model & Measure Page, Select Appropriate Business Model & then select associated Fact / Measure.

Q86. Which component is responsible for determining the device that receives the alerts for a given user account?

Dashboard

iBot

Alerts

Delivery Profiles

Explanation
Intelligent Bursting and Output Tool (iBot).
iBot is an utility available in OBIEE which is used for reports scheduling as well as Alerts sent to the required recipients on different web accessible / communication devices.

Q87. Which are the three types of tables available to physical tables in the physical layer?

Physical Table

Stored Proc

Select

View

Table

Pull the table and column definition into the physical layer
Use the OBIEE “import metadata” wizard to pull the table and column definition into the physical layer. The wizard is used so that all of the column definitions do not need to be manually added into the physical layer.
Figure:

Note: The physical layer is the layer of the Logical Business Model where you define the physical data model of your data source. It contains information about the physical data sources.

Q88. A derived measure is never used to_________.

Calculate share measures

Add two logical columns together

Calculate a variance between two measures

Calculate the rank dimension values

Input data

Q89. Point-and-click generation of case statement logic can be accessed via which option?

Column Formula-> Bins tab

Compound Layout

Column Properties -> Conditional Format tab

Advanced Tab

Subject Area metrics

The “Edit Column Formula” dialog box has a second, very tiny tab called, “Bins.” You can use this tab to have OBIEE build a CASE statement for you in a formula (you can also create a CASE statement yourself by using one of the functions that appears under “Expressions” if you want). A CASE statement is a lot like an IF-THEN-ELSE statement, except that it’s a little easier to read when you have multiple options. Basically, it puts values in different buckets that you define.
Note: Figure:

Q90. Which three options apply to FMW Application Roles?

Provide an indirection between LDAP groups and BI roles

Can be exported / moved between FMW11g environments

Are created and managed by using the WLS Admin Console and FMW Control

Can be created by using BI Administrator Client and “pushed” to WLS Admin Console

Secures RPD permissions but NOT Web Catalog (webcat) permissions

Explanation
A: The default Application Roles available after OBIEE 11g installation are BIAdministrator, BISystem, BIConsumer and BIAuthor.
Note: In OBIEE 11g, Application roles provide insulation between permission definitions and corporate LDAP Groups. Permissions are defined at Application Role level and changes to LDAP groups just require a reassignment of the Group to the Application Roles.
See figure below:

security_12.jpg
C: Application Roles, Policies, association of Policies to application roles and association of users and groups to application roles are managed using Fusion Middleware Enterprise Manager (FMW EM).
E: Object level permission association to Applications Roles resides in the RPD for repository objects.
Permissions and Privilege for web catalog objects resides in the OBIEE Web Catalog. Wherever Groups were used in the web catalog and RPD has been replaced with Application roles in OBIEE 11g.
Note: Application Roles are introduced in OBIEE 11g. An application role is specific to the application. They can be mapped to other application roles defined in the same application scope and also to enterprise users or groups, and they are used in authorization decisions.

Q91. What are the two methodologies that are followed within an OBIEE implementation?

Do not use prototypes

Use an iterative approach

Start with a small model and then enhance the repository

Start with a big repository and trim it down with the requirements

Explanation

Q92. Which configuration can be changed through Enterprise Manager?

Minimum Number of Rows to Download to Excel

The default BI Server Repository

Start and Stop BI Services

Manages user login

The Repository can be configured within the Enterprise Manager. See Note 1 below.
Note 1:Once you’ve locked the Oracle BI Domain, you would then use the same screen back in
Enterprise Manager to browse and select the RPD file, and then enter the password, twice.

NewImage Once you’ve entered these details you would then press the Apply button, to save the changes. At this point, the RPD gets a sequence number after it, and it’s displayed as the current default online repository for the Oracle BI Domain.
Note2: An OBIEE 11g system (or “Oracle BI Domain”) is generally managed through a combination of Oracle Enterprise Manager Fusion Middleware Control, part of the Enterprise Manager “family”, or through WebLogic Server Scripting Tool (WLST) scripts. Each Fusion Middleware Control instance as shipped with OBIEE 11g controls a single Oracle BI Domain (DEV, or PROD for example), and is installed along with WebLogic Server Admin Console in the WebLogic Admin Server, one of the two JVMs (the other being the managed server) that gets installed by default with OBIEE 11g. The screenshot below shows Fusion Middleware Control showing the status of the BI Server, Presentation Server and other system components within the installation.

Q93. A customer frequently queries multiple dimension tables without a measure. What needs to be defined in the presentation layer?

Logical Key

ImplicitFact Column

Alias

Logical Column Name

CustomDisplay Name

You can define calculations in either of the following ways:- Before the aggregation,
in the logical table source. For example:sum(col_A *( col_B))- After the aggregation, in a logical
column derived from two other logicalcolumns. For example:sum(col A) * sum(col B)

Q94. Which three components are part of a cluster server?

Q95. Under what circumstances would you model within the BI environment to include transactional data directly?

When the customer needs near real-time data to support decision making in a fast changing environment

When the customer is not prepared to spend budget on data-warehousing

When the complexity of operational schema does not allow modeling in the BI repository

When it is not possible to query against a transactional system
