Question
How does system integration create a cohesive large-scale system?
Page 1
Answer
It combines different subsystem components so they operate together effectively. Key forms include EAI, Data Integration, and EDI.
2
Question
How does system architecture support understanding of a system?
Page 1
Answer
It formally represents the system’s structure, behavior, key views, components, and relationships.
3
Question
When requirements elicitation begins, which two problems must it address?
Page 1
Answer
It identifies stakeholder needs and defines system boundaries.
4
Question
How does brainstorming contribute to requirements elicitation?
Page 1
Answer
It uses group discussion to generate new ideas and possible solutions.
5
Question
When existing manuals and business artifacts contain useful information, which elicitation technique applies?
Page 1
Answer
Document analysis reviews existing system documentation, manuals, and business artifacts to gather relevant details.
6
Question
How does interface analysis identify integration requirements?
Page 2
Answer
It examines interaction points between users and systems or between systems and subsystems.
7
Question
What distinguishes observation from interviews during requirements elicitation?
Page 2
Answer
Observation watches end users perform tasks in normal environments. Interviews use one-on-one or structured question-and-answer sessions with stakeholders.
8
Question
How does a rapid throwaway prototype differ from an evolutionary prototype?
Page 2
Answer
A rapid throwaway prototype is discarded after requirements validation. An evolutionary prototype is continually refined into the final product.
9
Question
When development is divided into progressively integrated modules, which prototype type applies?
Page 2
Answer
An incremental prototype is built in modules or chunks that are progressively integrated.
10
Question
How does extreme prototyping organize web development?
Page 2
Answer
It separates development into UI/UX wireframes, functional services, and back-end integration.
11
Question
Why do requirements workshops involve cross-functional stakeholders?
Page 2
Answer
Facilitated sessions bring different stakeholder groups together to reach agreement on scope and needs.
12
Question
How does reverse engineering recover requirements from a legacy system?
Page 2
Answer
It analyzes the existing system or application to extract design and requirement details.
13
Question
When a large user population must provide information, which elicitation method is appropriate?
Page 2
Answer
Surveying or questionnaires collect information from a large group of users.
14
Question
What makes a survey more likely to produce actionable requirements?
Page 2
Answer
Keep it short, state objectives clearly, avoid negative or defensive questions, remove overly complex concepts, and request actionable details.
15
Question
How do interfaces and messages support communication between integrated systems?
Page 2
Answer
Interfaces provide physical or logical communication connections. Messages are structured information units exchanged across those interfaces.
16
Question
Which two parts must a UML message contain?
Page 2
Answer
Event and Information.
17
Question
How does EAI coordinate applications across an enterprise?
Page 2
Answer
Enterprise Application Integration uses frameworks, methods, and tools to classify, connect, and coordinate software applications.
18
Question
How does UN/EDIFACT structure one transfer unit?
Page 3
Answer
It contains Event, Reference Data, and Control Information.
19
Question
What problem does XML address in electronic data exchange?
Page 3
Answer
XML supports structured data exchange and includes complementary standards such as XSL.
20
Question
How does a use case model connect actors with system behavior?
Page 3
Answer
It illustrates how actor types interact with a system to perform tasks or solve problems. It is formally represented using UML.
21
Question
Why does a use case model support both requirements and testing?
Page 3
Answer
It captures functional requirements, validates system architecture, and helps generate and implement test cases.
22
Question
In a use case diagram, how do the actor and system boundary differ?
Page 3
Answer
An actor is an external user or system interacting with the system. The system boundary separates internal functionality from external actors.
23
Question
Which modeling technique uses flow objects, connecting objects, swimlanes, and artifacts?
Page 4
Answer
BPMN (Business Process Modeling Notation).
24
Question
How does a DFD differ from a flowchart in its primary focus?
Page 4
Answer
A DFD maps data through processes, inputs, outputs, and storage. A flowchart uses shapes and arrows to define steps, decisions, and paths.
25
Question
Which technique maps enterprise functions through ICOM elements?
Page 4
Answer
IDEF (Integrated Definition). ICOM means Inputs, Controls, Outputs, and Mechanisms.
26
Question
How does RID represent interactions within a system?
Page 4
Answer
It illustrates interactions among roles or processes. Sequence diagrams show chronological interactions, whereas collaboration diagrams show structural interactions.
27
Question
Which three categories classify business analysis tools?
Page 5
Answer
Requirement-related tools, modeling tools, and collaboration tools.
28
Question
How does project initiation differ from project planning?
Page 5
Answer
Initiation establishes business justification and feasibility. Planning establishes the roadmap, scope, budget, and task schedule.
29
Question
Which five phases form the PMI project management life cycle?
Page 5
Answer
Initiation, Planning, Execution, Monitoring & Controlling, and Closure.
30
Question
How does a WBS transform project work into a manageable plan?
Page 6
Answer
It hierarchically and incrementally breaks project work into distinct phases, deliverables, and work packages.
