Online Test: „CPRE Knowledge“
Unfortunately, it wasn’t quite enough this time.
You have not answered the required number of questions correctly. Only {quiz_percent} percent of the questions have been answered correctly.
Of course, you can repeat the online test at any time.
It might also be a good idea to invest some time in the basic techniques, methods, and terminology of requirements engineering to get a higher score on your way to becoming a Certified Professional for Requirements Engineering.
Overview of questions and answers:
Question 1
Fundamental Principles of Requirements Engineering
During the Requirements Engineering process for an online database, you find out that data protection regulations do not apply, as the data processed by the system is anonymized.
What will be influenced by this finding?
- The system boundary
- The context boundary
- System interfaces
- Gray zone of the system boundary
Key

Question 2
Work Products and Documentation Practices
To support young actors and directors, a contest for short films is held. The three best films will be presented with an award. The films submitted must have a maximum length of 20 minutes and must take the constraints depicted in the following diagram into consideration.
Which of the following statements match the above diagram?
- Three directors may direct a film collaboratively.
- A film with only one actor may be submitted.
- A director may direct two films submitted.
- An actor may star in any number of films.
- A film must have ten actors starring in it.
Question 3
Practices for Requirements Elaboration
The Kano model states that dissatisfiers (basic factors) are hard to elicit.
Which of the techniques mentioned below is the best elicitation technique for dissatisfiers?
- Interview
- Questionnaire
- Field observation
- Brainstorming
Question 4
Work Products and Documentation Practices
You want to design a requirements document in such a way that it is particularly well suited for the people who will work with the document in further phases of the development process.
From the following sentences, choose the two best combinations of the role and its criteria for the requirements.
- For the testers, it must be possible to realize the requirements.
- For the developers, it must be possible to change the requirements easily.
- For all people involved, the requirements in a work product have to be consistent.
- For the project manager, the requirements have to be necessary.
- For the maintenance staff, it must be possible to prioritize the requirements.
Question 5
Work Products and Documentation Practices
A company wants to introduce an authorization process for accessing confidential parts of the company’s intranet by issuing time-limited passwords.
Determine which of the following requirements are modeled correctly in the state diagram above.
- Blocked users can be unblocked by resetting the user’s password.
- If abuse has been determined, the password has to be blocked.
- If the validity period has expired, the password has to be deleted.
- If an application is approved, no new application can be created.
Question 6
Work Products and Documentation Practices
The following activity diagram represents performing a measurement.
Which of the following statements match the above diagram?
- Initialize measuring device must happen prior to Register at server.
- Register at server happens as soon as Load certificates is ready.
- Initialize network connection and Load certificates must finish at the same time.
- Deactivate measuring device is executed as soon as Data receipt confirmed is true.
Question 7
Practices for Requirements Elaboration
In your project, a new braking system for high speed trains is developed.
Which validation technique is most suitable for this situation, where the system requirements of a safety-critical component should be validated?
- A/B testing
- Prototype
- Walkthrough
- Inspection
Question 8
Practices for Requirements Elaboration
You have produced a requirements baseline and delivered it to development. In the meantime, stakeholders have submitted change requests for requirements of this baseline.
Which of the following answers represent correct change management for requirements?
- Changes with regard to requirements that are part of the baseline are implemented through the creation of new versions of the requirements within this requirements baseline.
- Prior to adjusting the requirements to the change requests, the impact of the changes has to be determined.
- Change requests can be submitted at any time and may be considered for development when creating a future baseline.
- Time-critical change requests are neither analyzed nor estimated but delivered directly to development.
- If the development for changed requirements has not started yet, the change can easily be processed without creating a new baseline.
Question 9
Process and Working Structure
Which two major facets below are the most important to consider when configuring an RE process?
- The time facet: linear vs. iterative
- The budget facet: tight vs. large
- The purpose facet: prescriptive vs. explorative
- The methodology facet: structure-based vs. process-based
- The interaction facet: team-driven vs. individual-driven
Question 10
Tool Support
Which of the following is NOT a capability of Requirements Engineering tools?
- Managing logical relationships between requirements
- Deriving test cases from requirements
- Generating documents from the requirements
- Supporting views on requirements
Are you already equipped with the perfect tool?
The technical knowledge of Requirements Engineering is an important basis for the daily work of the requirements engineer. It is equally important to rely on the right tools that can support you in your work.
Take a look at our toolbox. For example, get to know the numerous features of objectiF RM, a software for requirements analysis, requirements modeling and requirements management.
Plus, you can even derive test cases from requirements ;-)
And how about your colleagues?
A common understanding of terms within a company and between business partners is just as important as the uniform use of techniques. This is the basis for sustainable project success.
Invite your colleagues to take the online test as well. Feel free to share it on social media and via email.
