Read the first 7 Software Development Lifecycle flashcards as text

  1. In a telecommunications network management system, which SDLC phase is most critical for defining SLA performance thresholds and uptime requirements?

    Answer: Requirements Analysis

    Requirements Analysis captures stakeholder needs including SLA thresholds and uptime targets before any design or coding begins.

  2. A telecom company discovers that its billing software has a defect that surfaces only when invoices exceed 10,000 line items. This type of bug is best caught during which SDLC phase?

    Answer: System Integration Testing

    System Integration Testing validates end-to-end behavior under realistic data volumes, catching edge cases that unit tests miss.

  3. Which software development approach is most appropriate when a telecom operator needs to rapidly prototype a new IoT device management portal with evolving requirements?

    Answer: Agile/Scrum

    Agile/Scrum accommodates changing requirements through iterative sprints, making it ideal for rapidly evolving IoT portal development.

  4. During the SDLC maintenance phase, a network operations software patch causes unexpected call routing failures. This scenario illustrates the need for:

    Answer: Regression Testing

    Regression Testing verifies that new patches do not break existing functionality, which would have caught the routing failure before deployment.

  5. A CTE candidate is reviewing an SDLC document that maps each requirement to a corresponding test case. This artifact is called a:

    Answer: Requirements Traceability Matrix

    A Requirements Traceability Matrix links each requirement to design elements and test cases, ensuring complete coverage.

  6. In telecom software projects, 'technical debt' accumulated during rapid feature releases is best addressed through which SDLC activity?

    Answer: Refactoring during maintenance iterations

    Refactoring during planned maintenance iterations systematically reduces technical debt without disrupting service continuity.

  7. Which metric best indicates the quality of the Testing phase in a telecom OSS/BSS development project?

    Answer: Defect escape rate to production

    Defect escape rate measures the percentage of bugs that reach production, directly reflecting testing effectiveness.
