Which of the following is a significant cause of failure when using the technology-focused approach to BI Application development?
Users often have difficulty understanding new technology.
New technology often contains internal flaws and errors that affect the delivered solution.
The solution is focused on a single subject area.
Developers often focus on just the data.
Which of the following statements is true about the Waterfall Approach?
The five steps in the process are considered valid for BI software development projects.
Each step is performed in sequence but you return to previous steps at specific points in the development cycle.
It is designed so that requirements that are not discovered in the Analysis step will cascade out during the design phase.
Project management tools no longer encourage the Waterfall Approach.
While Cognos 8 BI will support any data warehouse design, which of the following designs does Cognos recommend for new warehouse development?
Operational Data Store
Dimensionally Modeled Relational
Normalized Enterprise
Dimensional Bus
Which of the following statements best describes the Iterative Approach of application development?
A prototype solution is developed after the initial user interviews. This prototype is then used as a basis for refining specific design requirements.
The design step is repeated multiple times before proceeding to the development step. Each pass through the design step further refines the eventual solution.
The solution is developed and delivered to the users. After approximately 2 weeks, the users are interviewed for any missing requirements and any new requirements form the
basis for the next iteration.
A prototype is created that addresses 80 to 90% of the business requirements. This is
demonstrated to the users and their feedback is used to refine the prototype in subsequent iterations.
Which of the following issues is Iterative Development specifically designed to address?
The very act of developing a system or solution will change the business requirements.
Users understand their business processes but they don't usually understand application development.
No developed solution will satisfy all users equally.
Users often feel that IT does not understand the business.
Why should an application's performance be monitored on an ongoing basis after it goes
into production?
Initial performance tests are usually too optimistic.
There is little value in performance tests before a system goes into production.
Usage patterns on applications tend to change over time.
New releases of system and application software usually degrade performance.
After a BI application is placed into production, all of the following are considered part of
the process to prepare for the next iteration of the application, EXCEPT:
Record and track enhancement requests
Communicate with users to insure the application is delivering value
Periodically re-apply the V-test model against the developed components
Enhance application documentation to reflect errors and omissions
Which of the following is the recommended method of implementing a regular backup plan
for a BI Application?
Implement a BI application backup plan separate from other production applications.
Back up the production application into the test environment.
Copy the BI application to a duplicate environment.
Integrate the BI application into existing production backup plans.
Which of the following describes an advantage of using the dimensionally modeled
relational (DMR) technique to access a normalized data structure?
Eliminates the need for aggregate tables
Reduces the time needed to fetch the required data
Enables drill up/down functionality in reports and ad hoc queries
Enables creation of IQDs for creating Power Cubes
Which of the following describes how Cognos 8 works with aggregate aware table in
relational data sources?
Cognos 8 can create aggregate aware tables within the database.
Cognos 8 redirects its generated SQL to take advantage of aggregate aware tables.
Cognos 8 does not make any specific adjustments for aggregate aware tables.
Cognos 8 can monitor reports that are run and suggest aggregate aware tables.
All of the following describe design intent of an operational database EXCEPT:
Record the day to day operations of the company
Maximize the speed of inserts and updates to the database
Enhance reporting through foreign keys and indexes
Facilitate performing specific functional tasks
Which of the following is a valid strategy for addressing failover for the content store?
Install active and passive instances of the content store.
Install active and passive instances of the Content Manager service.
Take advantage of failover protection in the Applications tier by installing the content store on a server that hosts multiple instances of the report service.
Take advantage of database backup and failover strategies and policies already in place in the environment.
Using the diagram below to install and configure Cognos 8 BI, which of the following
components will NOT address automatic failover?
Cognos 8 BI Content Manager (Active)
Cognos 8 BI Content Manager (Passive)
Cognos 8 BI Report Server
Cognos 8 BI Gateway
