DIS Software Development Lifecycle 2 — Questions and Answers
Question 1: In the context of digital imaging software, which SDLC phase is responsible for defining color profile support and resolution requirements?
- Design
- Requirements Analysis (Correct answer)
- Implementation
- Testing
Correct answer: Requirements Analysis
Requirements Analysis captures functional and non-functional needs such as color profile support and resolution constraints before design begins.
Question 2: A Scrum team working on an image processing tool completes work in two-week increments. What is this increment called?
- Milestone
- Sprint (Correct answer)
- Release cycle
- Kanban board
Correct answer: Sprint
In Scrum, a Sprint is a fixed-length iteration (commonly two weeks) during which the team delivers a potentially shippable product increment.
Question 3: Which type of testing verifies that a new imaging feature does not break existing functionality in the software?
- Unit testing
- Regression testing (Correct answer)
- Smoke testing
- Acceptance testing
Correct answer: Regression testing
Regression testing re-runs existing test cases to confirm that recent changes have not adversely affected previously working features.
Question 4: In Agile SDLC, the product backlog is primarily owned and prioritized by which role?
- Scrum Master
- Development Team
- Product Owner (Correct answer)
- QA Lead
Correct answer: Product Owner
The Product Owner is responsible for maintaining and prioritizing the product backlog to maximize the value delivered by the team.
Question 5: A digital imaging company uses a change control board (CCB) to approve modifications mid-project. This practice is most characteristic of which SDLC model?
- Extreme Programming (XP)
- Kanban
- Waterfall (Correct answer)
- Scrum
Correct answer: Waterfall
Waterfall's strict sequential phases use formal change control boards to manage scope changes because altering requirements late is costly.
Question 6: What does 'Definition of Done' mean in an Agile imaging project?
- The project sponsor signs off on the final deliverable
- A shared checklist that a feature must satisfy before it is considered complete (Correct answer)
- The QA team closes all open bug tickets
- The product is deployed to production
Correct answer: A shared checklist that a feature must satisfy before it is considered complete
The Definition of Done is a team-agreed checklist of criteria (coded, tested, documented, reviewed) that every increment must meet before it can be accepted.
Question 7: During which SDLC phase would a digital imaging team produce a System Design Specification (SDS) document?
- Requirements Analysis
- System Design (Correct answer)
- Coding
- Maintenance
Correct answer: System Design
The System Design phase translates requirements into architecture and produces the SDS, detailing modules, data flows, and interfaces.
