Free Software Design and Architecture MCQs with Answers

• A. Top-down decomposition approach
• B. Divide and conquer principle
• C. Graphical representation of results using DFDs
• D. All of the mentioned

Explanation: Structured analysis breaks a system down from the whole into smaller functions, using divide-and-conquer and graphical DFD notation to…

• A. Support structured analysis and design (SA/SD)
• B. Maintains the data dictionary
• C. Checks whether DFDs are balanced or not
• D. It complies with the available system

Explanation: CASE tools can support structured analysis, maintain data dictionaries, and verify DFD consistency such as balancing.

• A. SDD
• B. SRS
• C. All of the mentioned
• D. None of the mentioned

Explanation: Function-oriented design derives its functions from the functional requirements documented in the SRS.

• A. A function such as "search-book" is represented using a circle
• B. Functions represent some activity
• C. Function symbol is known as a process symbol or a bubble in DFD
• D. All of the mentioned

Explanation: A function represents an activity or process, and in a DFD it is shown as a circle or bubble, such as “search-book.” Thus, all the…

• A. It consists of module definitions
• B. Modules represent data abstraction
• C. Modules support functional abstraction
• D. None of the mentioned

Explanation: Function-oriented design organizes modules around functions, so the modules support functional abstraction.

• A. Logical Cohesion
• B. Temporal Cohesion
• C. Functional Cohesion
• D. Coincidental Cohesion

Explanation: Coincidental cohesion is the weakest form because the elements in a module have no meaningful relationship beyond being grouped together.

• A. Functional Cohesion
• B. Temporal Cohesion
• C. Functional Cohesion
• D. Sequential Cohesion

Explanation: Temporal cohesion groups tasks because they occur during the same time period, such as startup or shutdown processing.

• A. Object oriented analysis
• B. Object oriented design
• C. Structured approach
• D. Both Object oriented analysis and design

Explanation: Object-oriented analysis and object-oriented design provide the object-oriented counterpart to the function-oriented approach.

• A. Control Coupling
• B. Stamp Coupling
• C. External Coupling
• D. Content Coupling

Explanation: Stamp coupling occurs when a module passes an entire record or data structure to another module, even when only part of it is needed.

• A. Cohesion
• B. Coupling
• C. None of the mentioned
• D. All of the mentioned

Explanation: Coupling measures how strongly modules depend on one another, while cohesion measures how closely the responsibilities within a single…

• A. Functions
• B. Modules
• C. Classes
• D. Sub procedures

Explanation: A module is a separately organized program unit that can contain related procedures or data; a Java package and a Fortran subroutine are…

• A. Control Coupling
• B. Stamp Coupling
• C. Data Coupling
• D. Content Coupling

Explanation: Data coupling is usually considered the best form because modules communicate only through the data values they need.

• A. Modules are robust
• B. Module can use other modules
• C. Modules Can be separately compiled and stored in a library
• D. Modules are mostly dependent

Explanation: Modularity aims for independent, robust modules that can be compiled separately, reused, and stored in libraries.

• A. Efficiency
• B. Accuracy
• C. Quality
• D. Complexity

Explanation: Software design provides the structure that guides implementation and helps achieve the overall quality attributes of the system.

• A. Program flowchart
• B. Structure chart
• C. Data-flow diagram
• D. Module

Explanation: A structure chart represents the hierarchical organization of modules and their calling relationships, making it a standard…

• A. Architecture
• B. Data
• C. Interface
• D. All of the mentioned

Explanation: Software design must address the system architecture, the data it manages, and the interfaces through which components and users interact.

• A. Forward engineering
• B. Reverse engineering
• C. Re-engineering
• D. Reconstructing

Explanation: Forward engineering moves from an abstract model or design toward an implementation such as source code.

• A. WINWIN Spiral Model
• B. Spiral Model
• C. Concurrent Model
• D. Incremental Model

Explanation: The concurrent development model represents activities such as analysis, design, and implementation as overlapping states, which suits the…

• A. True
• B. False

Explanation: Activity diagrams represent workflows and the flow of control or data through processing activities.

• A. True
• B. False

Explanation: Model-driven engineering can transform models into source code or executable artifacts through model transformations and code generators.
