CTE Software Development Lifecycle 2

Question 1

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

Accepted Answer

Requirements Analysis

Answer

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

Question 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?

Accepted Answer

System Integration Testing

Answer

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

Question 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?

Accepted Answer

Agile/Scrum

Answer

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

Question 4

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

Accepted Answer

Regression Testing

Answer

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

Question 5

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

Accepted Answer

Requirements Traceability Matrix

Answer

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