BCS PC-BA-FBA-20 Practice Test 1

Which of the following elements of a use case diagram is used to indicate those who expect to receive a service from the system?
Actors.
System boundaries.
Users.
Entities.
A use case diagram is a visual representation of how users (or systems) interact with a system to achieve specific goals. Actors represent the entities (e.g., users or external systems) that expect to receive services from the system.
Key Elements of a Use Case Diagram:
Actors: Represent individuals or systems that interact with the system to achieve a goal.
System Boundaries: Define the scope of the system being modeled.
Users: While 'users' may seem similar to actors, the term 'actors' is the correct technical term in use case diagrams.
Entities: Entities typically refer to data objects or components, not those receiving services.
Evaluation of Each Option:
A . Actors: Actors are the correct element used to indicate those who expect to receive a service from the system. Conclusion: This is correct .
B . System boundaries: System boundaries define the scope of the system but do not represent those receiving services. Conclusion: This is not correct .
C . Users: While users may interact with the system, the correct term in use case diagrams is 'actors.' Conclusion: This is not correct .
D . Entities: Entities represent data objects or components, not those receiving services. Conclusion: This is not correct .
