NEW QUESTION # 96
Which of the following requirements are NOT in accordance with the template "[] []"? (Select 2 answers.)
- A. If the user logs in, the system shall display the user's profile within 2 seconds.
- B. Within 2 seconds, the system shall notify the administrator upon receiving a critical alert.
- C. If the user selects 'Print' the printer shall generate a PDF file in less than 10 seconds.
- D. When the temperature exceeds 80°C, the control unit shall shut down the heater for 10 minutes.
- E. If the payment fails, the system shall display within 1 second.
Answer: B,E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The phrase template specifies that an optional condition comes first, then subject, action, objects and finally an optional restriction. Options A-C respect this order and provide all elements: condition ("If/When ..."), subject ("system", "control unit", "printer"), action, object and a final restriction. In D the time restriction is placed at the beginning and the condition ("upon receiving a critical alert") is embedded incorrectly, violating the template's structure. In E, the object of the action ("what" the system shall display) is missing, so the sentence is incomplete. Thus, D and E do not comply.

NEW QUESTION # 109
Which of the following prototype types are not used in Requirements Engineering? (Select 2 answers.)
- A. Experimental prototype
- B. Technical feasibility prototype
- C. Mock-ups
- D. Exploratory prototype
- E. Evolutionary prototype
Answer: A,B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
The handbook identifies three major prototype types in RE: exploratory prototypes (to establish shared understanding and validate requirements), evolutionary prototypes (early versions that grow into the final system) and mock-ups (medium-fidelity UI or interaction prototypes). These support elicitation and validation. Experimental prototypes, by contrast, are built mainly to evaluate technical solution concepts and feasibility; they belong more to design/architecture than RE. "Technical feasibility prototype" is not an official category and overlaps with experimental prototypes. Hence B and D are the ones not considered RE prototype types.
NEW QUESTION # 110

NEW QUESTION # 112
Which of the following criteria favour adopting a customer-specific RE process? (Select 2 answers.)
- A. The developing organization plans to sell the system as a product on a market.
- B. The customer wants a requirements specification that can serve as a contract.
- C. Prospective users are not individually identifiable.
- D. Requirements must match envisaged needs of broad user segments.
- E. The system will be used mainly by the organization that orders and pays for it.
Answer: B,E
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
A customer-specific process is appropriate when a single organization commissions a system primarily for its own use. In this context, a detailed specification often serves as a contractual basis between customer and supplier, making A a strong indicator. Likewise, if the principal users are within the ordering organization, tailoring requirements directly to that customer's needs (B) is typical. When users are anonymous or broad market segments are targeted (C, D, E), a market-oriented RE process-focusing on generic personas and segments-is recommended instead. Thus, A and B favour a customer-specific approach.
NEW QUESTION # 113

NEW QUESTION # 116
The scope of the system equals:
- A. The boundary between the system and its surrounding context.
- B. The range of things that can be shaped or designed while developing a system.
- C. The portion of the system environment relevant for understanding the system and its requirements.
- D. Everything that is inside the system boundary.
Answer: B
Explanation:
Comprehensive and Detailed Explanation From Exact Extract:
IREB distinguishes system boundary, system context and scope of the system. The system boundary separates the system from its environment. The system context is the relevant part of the environment needed to understand the system and its requirements. The scope describes what can be influenced or shaped during development-the range of aspects we intend to design or modify. Some elements inside the scope may lie outside the final system boundary (e.g., organizational processes); likewise not everything inside the boundary must be in scope. Hence the correct definition is option B.
