Explanation/Reference:
You are creating a mapping of the servers, workstations, printers, and other connected devices and their purposes for an analysis of how information is input, processed, stored, and output from each system. This is a description of a data flow diagram.
B is incorrect. A data dictionary defines the key terms and data relevant to a business domain.
D is incorrect. A network topology does show the connected devices to a network, but it does not
show how the information is input, processed, stored, and output from these devices.
C is incorrect. A prototype is a mock-up or working model of a proposed solution.

The most common non-functional requirements categories include availability, compatibility, functionality, maintainability, performance efficiency, portability, reliability, scalability, security, usability, certification, compliance, localization, service-level agreements, and extensibility.

Explanation/Reference:
Assumptions and constraints are identified through elicitation from stakeholders.
D is incorrect. Assumptions and constraints are not identified through document analysis.
C is incorrect. Assumptions and constraints are not identified through risk identification, though
false assumptions may be subject to risk analysis.
A is incorrect. Assumptions and constraints are not identified through a review of project
requirements.

Explanation
The two key objectives when organizing requirements are to understand which models are appropriate for the business domain and solution scope and to identify model interrelationships and dependencies.
Answer B is incorrect. This is not a valid statement about the task of organizing requirements.
Answer D is incorrect. Each requirement will have a key performance indicator, but it's not an element for
organizing requirements.
Answer A is incorrect. There is not a structural or organizational reason to sort requirements by functional or
non-functional decomposition.
