A telecom software team uses Continuous Integration (CI) pipelines. Which SDLC principle does CI most directly support?
Answer: Frequent small integrations catch defects early
CI embodies the principle of integrating code changes frequently so defects are detected and resolved while context is fresh.
During which SDLC phase would a telecom architect decide between a microservices vs. monolithic architecture for a new 5G network orchestration platform?
Answer: System Design
System Design is where high-level architectural decisions, including service decomposition strategies, are made based on gathered requirements.
A telecom CTE exam scenario shows a project where end users sign off on the software before go-live. This sign-off occurs during:
Answer: User Acceptance Testing (UAT)
UAT is the final validation phase where actual end users confirm the software meets their business needs before production deployment.
Which SDLC model is characterized by a 'V' shape where each development stage has a corresponding testing stage directly opposite it?
Answer: V-Model
The V-Model pairs each development phase (requirements, design, coding) with a corresponding verification or validation testing phase.
In a DevOps-enabled telecom software pipeline, 'shift-left testing' means:
Answer: Conducting testing earlier in the SDLC
Shift-left testing moves quality activities earlier in the SDLC to detect defects when they are cheapest to fix.
A telecom OSS project uses story points to estimate effort in two-week sprints. This estimation practice is associated with which SDLC methodology?
Answer: Scrum
Scrum uses story points and time-boxed sprints as core planning and estimation mechanisms for iterative development.
When a telecommunications company retires a legacy mediation platform, which SDLC phase governs the data migration and system decommissioning plan?
Answer: End-of-Life/Retirement
The End-of-Life/Retirement phase covers decommissioning, data archiving, migration, and safely sunsetting legacy systems.
