1. Which integration strategy adds components one at a time starting from the lowest level of the system hierarchy? → Bottom-up integration
2. For organizations that do not follow the principles of ISO/ICE/IEEE 15288 or the SEBoK to specify their life cycle processes this handbook can? → add significant value in new domains, if appropriately applied
3. When decomposing a system architecture, which criterion is most important for defining subsystem boundaries? → Minimizing coupling between subsystems while maximizing internal cohesion
4. As more systems engineers accept and use common terminology, SE will experience improvements in communications, understandings and ultimately. → Productivity
5. Which method is commonly used in ASEP trade studies to rank alternatives by assigning weighted scores? → Weighted scoring matrix (Pugh matrix)
6. During the implementation phase, the project plan is put into motion and the work of the project is performed → True
7. Which tool is used to visualize the hierarchy of objectives and sub-objectives in a trade study? → Objectives tree (value hierarchy)
8. Which concept describes the practice of hiding internal implementation details of a component behind a well-defined interface? → Encapsulation
9. What architectural pattern is most appropriate when a system must process data through a series of sequential transformations? → Pipe-and-filter pattern
10. In reliability block diagrams (RBDs), components arranged 'in series' means: → All components must function for the system to function
11. What is 'requirements traceability' in the context of stakeholder needs? → The ability to link each system requirement back to a stakeholder need it addresses
12. The Systems Development Life Cycle (SDLC) is a _________ for describing the phases involved in developing and maintaining information systems → Framework
13. In technical planning, the primary purpose of creating a Work Breakdown Structure (WBS) is to: → Provide a hierarchical, deliverable-oriented decomposition of the project scope.
14. What does 'availability' mean in systems engineering? → The fraction of time a system is in a functional and ready state
15. In eliciting stakeholder needs, which technique involves observing users in their actual work environment? → Ethnographic study / contextual inquiry
16. In a trade study, 'discriminating criteria' are those that: → Clearly differentiate the performance of the alternatives being compared
17. The functionality of a system is typically expressed in terms of? → The interaction of the system with its operating environment, especially the users.
18. Which architectural trade-off is most directly addressed by selecting between centralized and distributed processing architectures? → Performance vs. fault tolerance
19. Why should the team that will use a system's output be involved in defining trade study criteria? → To ensure the criteria reflect operational needs and effectiveness from a user perspective
20. In a fault tree analysis (FTA), the top-level event represents: → The undesired system-level event that the analysis seeks to prevent
21. An IPO diagram includes the following → All inputs, predictable activities and required outputs
22. In a modular architecture, what does 'high cohesion' within a module indicate? → The module's internal elements are strongly related and focused on a single purpose
23. As more systems engineers accept and use common terminology, SE will experience improvements in communications, understanding and ultimately? → Productivity
24. During decision analysis, which of the following is the FIRST step a systems engineer should perform? → Define the decision criteria
25. Which of the following best describes a 'decision gate' in the system life cycle? → A formal review point where stakeholders authorize progression to the next phase
26. Which of the following is an example of a well-written, atomic requirement? → The system shall authenticate users against the corporate LDAP directory.
27. What is the primary purpose of a Configuration Item (CI) identification process? → To select and uniquely identify items that need configuration control
28. In systems engineering, what does 'voice of the customer' (VOC) analysis help achieve? → Translating customer statements into actionable system requirements
29. Which of the following activities is central to the Requirements Definition process, transforming stakeholder needs into a technical view of the solution? → Creating a set of verifiable system requirements
30. Other than the Leaning tower of Pisa, what other European construction is leaning? → Big Ben
