CBAP Exam - Question 337

A business analyst (BA) is working on a payment system (PS) implementation. A set of systems which should interact with a new system has been identified. The business analyst defined that a user with role of "Supervisor" in the PS must pass a two-factor authentication before an execution of the functions: "Change system parameters" and "Set up new supervisor." A user must have the role of "Supervisor" to use the standard functions "Send mail notification" or "Send SMS notification".

The BA defined the following use cases:

"¢ "Change system parameters"

"¢ "Setup new supervisor"

"¢ "Send mail notification"

"¢ "Send SMS notification"

"¢ "Send notification"

"¢ "Pass a two-factor authentication"

The BA wants to create a Use Case diagram.

Which technique should be used to define a communications protocol between the PS and other systems?

Show Answer
Correct Answer: BD

To define a communications protocol between systems, the appropriate technique is Interface Analysis. This method involves identifying where, what, why, when, how, and for whom information is exchanged between solution components or across solution boundaries. This technique is vital for ensuring smooth interaction and interoperability between different systems, which is essential for defining communications protocols.

Ans-Concept Modelling A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any kind of variation of a physical quantity. The protocol defines the rules, syntax, semantics and synchronization of communication and possible error recovery methods. A “concept model starts with a glossary, which typically focuses on the core noun concepts of a domain.” The case study asking about communication protocol which include several rules. “It is especially important where high precision and subtle distinctions need to be made. Concept models can be effective where:… the initiative needs to capture large numbers of business rules…”

i guess i'm wrong .Ans- Interface analysis - • Clear specification of the interfaces provides a structured means of allocating requirements, business rules, and constraints to the solution.(Babok Page-290). i got carried away by word business roles in concept modelling, rules for communication can be defined in interface analysis.

The question stands for "How to define a communication protocol with others systems ?", which it's not only an interface (manual input), but also a language between 2 systems. Mail are using SMTP, protocol, SMS are using the GSM protocol. Answer D is correct. You should analyse the whole system, not only the interface between the supervisor and the PS system.

D. System Analysis: - Focuses on studying the requirements, components, and functionalities of a system. - Aims to understand the behavior, structure, and internal workings of the system. - Involves analyzing the system's processes, data flows, and interactions within the system itself. - Helps in identifying system requirements, constraints, and potential improvements. B. Interface Analysis: - Concentrates on analyzing the interactions and communication protocols between different systems or components. - Aims to ensure smooth integration and interoperability between systems or subsystems. - Involves defining and designing interfaces, data exchanges, and protocols between systems. - Helps in identifying compatibility issues, data format standards, and data exchange mechanisms for effective communication between systems. Answer is B.
