,1. Question 1
A legacy enterprise system is being refactored into a microservices
architecture. To truly realize the benefits of scalability and
maintainability, which design principle should be most emphasized?
A. Tight coupling with a shared database
B. Modularization using loose coupling and high cohesion
C. Synchronous communication among all components
D. Centralized control via a monolithic service
ANS: B
Rationale: Breaking the system into independent, loosely coupled
modules (with high cohesion) minimizes interdependencies and allows
each service to be developed and scaled independently, which is the core
advantage of microservices.
2. Question 2
When selecting an architectural pattern to build a highly resilient and
scalable web application, which of the following is best suited for
isolating failures and accommodating independent deployments?
A. Layered (n-tier) architecture
B. Client‑server architecture
C. Microservices architecture
D. Monolithic architecture
ANS: C
Rationale: Microservices architecture partitions the system into small,
independent services that can fail without affecting the entire
application, thereby enhancing resilience and scalability.
3. Question 3
Within a modern CI/CD pipeline, which stage is least likely to be
included as a standard procedural step?
A. Automated code commit and build
B. Automated testing
C. Production deployment

, D. Final requirements elicitation
ANS: D
Rationale: CI/CD pipelines focus on code integration, testing, and
deployment automation. Requirements elicitation is a pre-development
activity and not part of the CI/CD automation process.
4. Question 4
Test‑Driven Development (TDD) is widely adopted in agile
environments. Which benefit is most directly attributable to TDD?
A. Achieving 100% code coverage by tests
B. Influencing better design decisions and modularization
C. Eliminating the need for exploratory testing
D. Reducing overall development time significantly
ANS: B
Rationale: TDD forces developers to think about the design and
interfaces of their code before implementation, resulting in more
modular and testable designs. It does not guarantee full coverage or
remove the usefulness of exploratory testing.
5. Question 5
In Agile projects, iterative development cycles are a hallmark. What is
the primary advantage of such iterations?
A. They reduce the need for formal documentation.
B. They allow for continuous feedback and adaptation to change.
C. They guarantee a perfect design from the start.
D. They postpone testing until after release.
ANS: B
Rationale: Iterative cycles promote rapid feedback from customers
and stakeholders, enabling teams to adjust and refine the product
continuously in response to changing requirements and environments.
6. Question 6
For advanced project estimation, which technique combines expert
judgment with historical data through iterative consultation?
A. Use‑Case Points Analysis

, B. Function Point Analysis
C. Wideband Delphi Technique
D. Story Point Scaling
ANS: C
Rationale: The Wideband Delphi technique leverages repeated
rounds of expert estimation combined with feedback, making it a robust
method for refining estimates by using both judgment and historical
context.
7. Question 7
In the early phases of software architecture design, quality attributes
like performance, modifiability, and security are established mainly to:
A. Determine the choice of programming language
B. Shape and guide architectural decisions and tradeoffs
C. Eliminate the need for later testing
D. Define the final user interface design
ANS: B
Rationale: Early identification of quality attributes is critical to making
informed architectural decisions and tradeoff analysis; these attributes
deeply influence design choices, independent of language or UI
considerations.
8. Question 8
Version control systems play a vital role in modern software
engineering. Which benefit best describes their contribution to ensuring
quality?
A. Preventing all coding mistakes
B. Tracking code history and enabling collaborative development
C. Automatically enforcing design patterns
D. Eliminating the need for code reviews
ANS: B
Rationale: Version control systems provide detailed histories,
facilitate collaboration, and allow rollback to known good states, all of
which support maintaining high code quality.
