TSE Quiz

In a payment processing system, the Transaction class provides public methods such as processPayment() and issueRefund(), while hiding its internal logic. To enable detailed business analytics, a developer proposes granting a separate reporting module direct access to the internal fields of the Transaction class. Which software engineering principle is most directly violated by this proposal?

• Low coupling

• Functional independence

• Abstraction

• Low cohesion

A logistics company builds a system to optimise nationwide delivery routes. To manage complexity, the system divides the problem by planning delivery routes separately for each region using localised routing strategies. The regional plans are then combined to form a unified schedule that avoids conflicts and improves overall efficiency. Which of the following benefits does this divide-and-conquer approach provide?

• Simplifies problem solving by breaking it into smaller subproblems

• Enables parallel processing of regional routes for faster computation

• Increases coupling by tightly integrating all regional plans

• Facilitates easier debugging and maintenance through modular design

Which of the following scenarios illustrates a violation of the Separation of Concerns principle?

• A class that validates user input and connects to a database

• A module that uses different classes to log, analyse, and export user actions

• A system where UI logic is separated from the backend processing

• A controller that delegates to service classes for all business logic

Which architectural flaw is most likely to emerge when loose coupling is not enforced?

• Code duplication due to reusability

• Rigid dependencies making modules hard to replace

• Increased cohesion of modules

• Excessive use of abstract interfaces

Which of the following statements about information hiding is true?

• It hides from users the details that are relevant to them

• It hides from users the details that are not relevant to them

• It hides from users the details that may be maliciously handled by them

• It hides from users the details that are confidential

Which of the following modelling techniques is used to model the relationship between objects in an object-oriented system?

• Use case modelling

• Entity-Relationship modelling

• Class modelling

• State modelling

Which design representation would best aid in verifying class completeness and cohesion before coding begins?

• Use-case diagram

• CRC model

• Deployment diagram

• Sequence diagram

Which UI design flaws are most likely to result in abandoned e-commerce sessions?

• Checkout button shown only when the cart is full

• Displaying raw code on failure

• Inconsistent navigation patterns

• Prefilled fields for returning users

Which of these framework activities is not normally associated with the user interface design processes?

• Interface cost estimation

• Interface validation

• Interface construction

• User and task analysis

What is the correct statement about software architectural design?

• The architectural design is normally expressed as a sequence diagram presenting an overview of the system structure

• The architectural design is normally expressed as a use case diagram presenting an overview of the system structure

• The architectural design is normally expressed as a state diagram presenting an overview of the system structure

• The architectural design is normally expressed as a block diagram presenting an overview of the system structure
